UPDATE
Issued at 701 PM CDT Thu Oct 27 2016
High res near term models backed off on fog a bit for tonight,
though will stay the course for now and maintain patchy fog as
inherited over my east and north central. Models trending to be
more favorable for fog development across the western Devils Lake
Basin, Turtle Mountains, and then across portions of the Souris
River Basin, where T/Td spreads are currently low. Already see vis
restrictions over northeastern ND. The James River Valley will
see the best potential for fog through 08-10Z before winds turn
more west/southwesterly.
Remainder of the forecast remains on track, relatively mild night
with BKN-OVC upper level clouds

.SHORT TERM...(This evening through Friday)
Issued at 232 PM CDT Thu Oct 27 2016
Concerns for the short term include fog across portions of the
east tonight. At 2 pm CDT a warm front extended from low pressure
centered in southern Saskatchewan through central North Dakota
with a cold front entering central Montana.
The HRRR and RAP models show the cool moist boundary layer air
remaining in place this evening across east central North Dakota.
Areas of fog and stratus are just breaking up in the afternoon
mixing with the models forecasting a return of the clouds and fog
this evening. Some uncertainty as the NAM/GFS not as certain on
fog but will add patchy fog and clouds in the evening and early
overnight east. Lows tonight will be relatively mild in the 40s
due to the general cloudiness.
On Friday the cold front will move through bringing northwest
winds and cooler air. This will also add some clouds with
cooling northwest , Highs will be in the 50s northwest to the
lower 70s southeast.
.LONG TERM...(Friday night through Thursday)
Issued at 232 PM CDT Thu Oct 27 2016
The extended will remain mildly progressive through the period
beginning with a series of shortwave troughs Saturday with another
Sunday into Monday. A long wave eastern Pacific trough will move
onshore pushing the ridge east and eventually trending toward a
split flow aloft by Wednesday and Thursday. The chance for showers
on Saturday will be across the far south with cooler air moving
through the region. A better chance for showers will be Sunday
night and Monday with the next shortwave. Temperatures should be
mild enough for rain showers although a rain/snow mix may be
possible far northwest Monday morning. Dry and seasonable weather
the rest of the week.

Livingston has gusted over 50 mph fairly often today, with a peak
of 59 mph noted around noon at the western DOT station. This a
result of gap flow modified by mixing into increasing
southwesterly mid level flow. RAP shows mountain top winds
increasing to 50 kts early this evening, so would expect 50+ mph
gusts to continue for a while longer, with pressure rises from the
west arriving around 03z likely to signal the start of a
decreasing trend. Have issued a wx story to highlight gusty cross
winds on I-90 at Livingston into this evening.
Water vapor imagery shows moist southwest flow over the western
CONUS with a split upper trof off the coast. It should be noted
that moisture is being aided by the remnants of Hurricane Seymour,
and pwats are expected to rise to around 0.75 inches in our region
by tomorrow, an impressive number for late October. Energy off the
coast of the Pacific NW will flatten the ridge tonight and allow
for cooler Canadian air to advect into our cwa. Expect highs back
to the 50s to mid 60s tomorrow, warmest in our southeast. Southern
split shortwave currently off the CA coast will lift through the
great basin tomorrow and bring a period of ascent in our cwa into
early Saturday. This will coincide with deepened upslope winds as
Canadian high pressure settles over the northern high plains.
Model spread remains high regarding the exact track of this trof
and mid level frontogenesis, with latest GFS/NAM showing a more
southern track, while the ECMWF is further north and affects more
of our cwa. Will keep forecast as a consensus between these two
possible solutions, raising pops across our south and lowering
them a bit in our north, as even the EC shows strongest
frontogenesis along the MT/WY border. Though this system will not
be overly dynamic, moisture content will be enough to yield over a
half inch of precipitation over our southern high terrain/upslope
areas. Snow will accumulate to several inches above 8000 ft, but
model wet bulb zero heights down to 6500 ft suggest a mix with wet
snow could occur over the slopes just above Red Lodge and Story.
Otherwise this is a mild system and will bring only rain to the
lower elevations. Precipitation will taper off from west to east
Saturday morning. Mostly dry conditions will prevail Saturday
afternoon. Our western mountains may see more rain/snow showers by
Saturday night as next Pacific shortwave approaches. Temps on
Saturday will be the coolest we have seen in quite awhile, maybe
two weeks, with highs in the upper 40s to mid 50s across the lower
elevations as lee side surface high is slow to exit.
Will continue to highlight Friday night precipitation in our
weather story. Hunters should take note of this upcoming period of
wet and cooler weather.

GFS/GEFS showed increasing model disparities with the pattern
beginning on Monday. The ECMWF ensembles did not show much
disagreement, however, the deterministic GFS and ECMWF were in
poor agreement with the pattern beginning on Tuesday. Kept changes
minimal to the forecast beginning on Tuesday due to the above. The
uncertainty in the models could be a result of Hurricane Seymour
getting into the model initializations.
Upper ridging will be over the forecast area on Sunday, but energy
from the next Pacific system will ride through the ridge, as well
as moisture into the western zones. Continue the slight chance to
chance PoPs from KBIL W per the previous forecast with the highest
PoPs in the far W. Noted LI`s fell to -2 deg/c on the GFS, but
soundings did not look like they would support thunder. It will be
warm with temperatures in the 60s across the area. The Pacific
energy moves into N WY/S MT Sun. night along with good moisture.
Models develop a strong surface low over NE WY/W SD by 12Z Monday
with decent QPF wrapping around the low into the area. Thus have
raised PoPs all areas to high chance/likely, except over SE MT
where models forecasted a dry slot. A few inches of snow are
possible over the western mountains. Energy lingers over the area
on Monday, as moisture gradually lessens from W to E. Raised PoPs
for this period as well. Expect a cooler day with highs around
normal. Monday night looks drier with chances of precipitation
confined to the mountains.
The model disagreement begins when the GFS brings a shortwave
through the area on Tuesday, while the ECMWF has upper ridging.
Both models were generally dry. An upper ridge develops on the GFS
for Wednesday while the ECMWF has an elongated trough from MT to
the four-corners region. Differences continued through Thursday.
Despite the differences, models were dry Wed. and Thursday. Model
blends kept temperatures near normal through the period. Arthur

18Z water vapor imagery and RUC analysis indicated large 592 dm H5
ridge in places across southern NM and TX. At the sfc...diffuse
trough axis was present across western CWA...separating area of
rather light westerly winds and stronger southwesterly flow.
H5 ridge over the area will be dominant weather feature through
tomorrow leading to dry conditions and passing high clouds
through the period. Main forecast impact through tomorrow will be
how dry things get each afternoon and resulting fire wx impacts.
Sfc observations,satellite soundings and DNR 12z raob all indicate
very dry air to the west of the area which will gradually drift
into area overnight. With afternoon mixing would not be shocked to
see dewpoints in the west fall into the lower 20s at some point.
This will drive humidities into the critical fire wx range, but
as was the case today winds will not be located with the driest

The overall pattern looks fairly quiet over the weekend into
early next week as the current upper high over southern Rockies
gradually flattens out over the weekend. A weak cold front will
slide through the area dry on Saturday dropping temperatures from
unseasonably warm 80s back into the 70s which is still a good
10-15 degrees above normal. After that, a series of weak short
wave troughs aloft eject out of the West Coast trough and move
over the central-northern Plains. This will bring another weak
cold front south, cooling temperatures back into the 60s Tue-Wed.
The next chance of precipitation looks to be at the end of the
forecast period from Wed night into Friday as a good chunk of
energy moves over the Rockies and into the Plains. Main problem is
the system that the models bring in is currently somewhere over
the dateline and likely not sampled well. Thus, model solutions
diverge quite a bit and confidence is low in the timing, location
and amount of any precip. Lowered pops from the init in that time
frame after collaborating with neighbors.

.DISCUSSION...See updated information for land areas below.
&&
.UPDATE...Upper air analysis this evening shows trof pivoting
eastward across the northeast US and Appalachians with mid-level
ridge building from the Baja to across Texas. With the upper trof
axis having passed the area, so goes what appears to be the final
chance of showers for the remainder of the month as an upper ridge
builds over the central Gulf coast over the next few days. With that
being said, October 2016 is poised to rank at the top of the
climatological record for Mobile and Evergreen as the driest.
Pensacola will likely come in as the 4th driest.
Drought conditions have worsened, becoming moderately to severely dry
over the area with rainfall over the past 30 days trending 3 to 6
inches below normal. Unfortunately, latest long term climatological
outlooks heading into the month of the November are not promising
much in the way of relief. A large area of below normal
precipitation is outlooked across the entire southern US from
California to Florida and the Mid-Atlantic. /10

DISCUSSION...Updated for latest aviation discussion below.
AVIATION...
00Z issuance...VFR conditions forecast this evening. Patchy late
night fog development possible which could lower vsby at MVFR levels
by and after 28.09Z. Light to calm winds overnight. /10
PREV DISCUSSION... /issued 331 PM CDT Thu Oct 27 2016/
NEAR TERM /Now Through Thursday night/...A weak shortwave trough
moving from northern AL into northern GA continues to dampen early
this afternoon, while an upper level ridge of high pressure over the
Desert Southwest and Southern Plains states slowly continues to build
eastward toward the Mississippi Valley region. Deep layer moisture
ahead of the shortwave trough axis remains very meager across our
forecast area this afternoon, and regional radar imagery shows no
precipitation developing in our area as of 3 PM CDT. This trend
places us on track to have zero rainfall at the Mobile Regional
Airport and a trace at Pensacola International Airport for the month
of October. See the Climatology section below for additional
details.
There is little change to the overall forecast reasoning through the
next 24 hours. The upper level ridge of high pressure will remain
centered over Texas through Friday afternoon, with the associated
ridge axis expected to gradually build eastward toward the Gulf Coast
region into Friday. Deep layer subsidence and dry air will support
keeping a dry forecast tonight and Friday. Decreasing cloud cover and
very shallow moisture profiles will favor potential for at least some
patchy fog development late tonight and early Friday morning,
particularly over southeast MS where the latest SREF and HRRR are
indicating potential for some locally dense fog. Later shifts will
monitor trends. Otherwise, we expect lows tonight to range from the
mid 50s to around 60 over interior areas to the lower to mid 60s near
the coast. Highs Friday are forecast to range from the mid to upper
80s over inland locations, and in the lower 80s near the immediate
coast and beaches. /21
SHORT TERM /Friday Through Saturday night/...Strong upper level
ridging over the Great Plains will become more zonal into the
weekend before redeveloping late Sunday into early Monday as a
series of low pressure systems dig from the Gulf of Alaska into the
Pacific northwest. At the surface, high pressure currently situated
over the lower Ohio River Valley will drift south into the southeast
U.S. into the weekend. Thus, strong subsidence over the region will
continue our pattern of dry weather and above seasonal temps. Highs
are expected to reach the mid to upper 80s inland and around 80
along the coast this weekend. Overnight lows will dip into the mid
to upper 50s inland to around 60 near the coast each night. /49
LONG TERM /Sunday Through Wednesday/...Upper level ridging builds
back into the eastern CONUS early to mid next week as a large region
of high pressure develops over the Florida peninsula and drifts west
across the Gulf of Mexico. Meanwhile, high pressure at the surface
will build from the mid-Atlantic coast southwest into the central
Gulf states. With this pattern, can expect to see a redevelopment of
weak onshore surface flow by early to mid next week. However, it
doesn`t look like moisture return will be sufficient enough to
warrant including any long term POPs...especially given the continued
strong mid and upper level subsidence over the forecast area. Expect
daytime highs to run above seasonal next week, with temps reaching
the mid 80s inland and low 80s near the coast each afternoon.
Overnight lows will range from mid to upper 50s inland to around 60
near the coast each night. /49
MARINE...A surface ridge of high pressure will continue to extend
across the Southeast states and the Central Gulf Coast region through
early next week. This pattern will support a light to moderate
northeast to east flow at night, and light to moderate east to
southeast during the day through the period. Seas will continue to
range from 3 to 5 feet well offshore through the weekend before
gradually subsiding into early next week. /21
CLIMATOLOGY...Our meteorologists have taken a closer look at the
climatology records for Mobile and Pensacola and have determined that
Mobile has officially only recorded one October with 0.00"
precipitation in 1874. There was a trace of precipitation recorded at
Mobile in October 1978. It is looking very likely that Mobile will
end the month of October 2016 with 0.00"
For Pensacola, there has only been a trace of precipitation recorded
this month. A trace of precipitation for the month of October was
last recorded at Pensacola in 1971. There have been 3 recorded years
of 0.00" October precipitation at Pensacola: 1952, 1963, and 1978.
Pensacola will likely end this month with only a trace of
precipitation. 34/21

.SHORT TERM...(This evening through Friday)
Issued at 318 PM CDT Thu Oct 27 2016
Main concern in the near term is timing of any clearing across the
region tonight and how warm to go Friday afternoon.
Pesky narrow band of light showers/sprinkles exiting west central
WIsconsin late this afternoon. It should remain dry the remainder of
the period. Lower clouds remain over most of the CWA this
afternoon...as moist lower level southeast/south flow continues.
Still anticipate overall lower cloud clearing trend to occur during
the night. Latest RAP showing lower level relative humidity clearing
to the northeast...along and north of I94 through about 07z. Slower
to clear into western Wisconsin. Southerly winds will remain up
overnight...so this will preclude significant fog from forming. Did
mention some patchy fog to the far east...where winds will be
lightest.
Warming ahead of the incoming cold front should warm temperatures
into at least the lower 70s to the southwest...record for MSP is 75
in 1948...with mid/upper 60s common elsewhere. The front will
contain a fair amount of high clouds...but we expect the lower
clouds to gradually break up over the far eastern areas into Friday
morning. They may return in the afternoon with the approach of the
cold front and lower level begin to saturate again. Will likely see
some wind gusts around 30 mph into the afternoon...mainly into south
central MN as the gradient tightens vicinity of the front.
.LONG TERM...(Friday night through Thursday)
Issued at 318 PM CDT Thu Oct 27 2016
A progressive weather pattern will set through next week with
several upper level waves brining areas of surface high pressure and
low pressure though the region. This will bring windy conditions
across the Upper Midwest. The best chance for rain will be Saturday
afternoon across central MN/WI, and again on Monday across northern
MN/WI. At this time no heavy precipitation is expected.
On Friday night a cold front will move through the region. H850
temperatures at forecast to go from 15C to around 0C between 00Z
Saturday and 00Z Sunday. This cold air advection will keep the
boundary layer mixed and Saturday will be cool and blustery with
northerly winds of 10 to 20 mph. An Upper Level shortwave will skirt
west to east across the region and lead to mid level clouds along
with some light rain, but accumulations should only be around a
tenth of an inch or less since this system will be weakening, not
strengthening.
Sunday will be the nicer day of the two this weekend as high
pressure builds across the region and then tracks eastward during
the day. Therefore expect light winds to start off the day, but then
a warm southerly breeze will ensue during the afternoon. Monday
winds will increase once again, and in fact will likely end up
higher than currently forecast, especially if there is some sun in
the warm sector across southern MN. Most of the precipitation will
stay north of I-94 on Monday.
Looking ahead, a cold front will push well south of the area Monday
night, but there is not much temperature advection. The rain will be
focused along this frontal boundary while high pressure brings dry
weather for the Upper Midwest.

The pesky deck of low clouds failed to erode for the most part
this afternoon. Therefore think the more pessimistic scenario for
tonight is the most likely to occur, despite the clearing that
some of the guidance continues to show. Have leaned toward the hi-
res models and what would normally happen climatologically-
speaking in this type of scenario. Have included low-end MVFR cigs
through the overnight hours (with the exception of KRWF), with
reduction to IFR cigs at northern/eastern sites. Could also see
some vsby reductions of the MVFR variety, but that to some extent
depends on what happens with the cloud cover. If we do stay
clouded in overnight, expect we would see scattering out during
the late morning hours Friday about the time we see the increase
in south/southwest winds, with VFR conditions for the remainder of
the period. Expect gusts to between 20 and 25 kts to develop by
the afternoon hours.
KMSP...
Confidence is low, but right now the more likely scenario is for
the site to stay clouded in with sub-1700 ft cigs through the
morning push. Anticipate scattering to VFR around 16z when
southerly winds also begin gusting to around 20kts.

.SHORT TERM...(tonight through Sunday)
Issued at 320 PM CDT Thu Oct 27 2016
Early-afternoon water vapor imagery revealed a mid-level ridge
edging east from the Rockies into adjacent High Plains, downstream
from a trough approaching the Pacific Coast. In the low levels, a
lee trough was deepening over the High Plains as of 18z with a
diffuse warm front that stretched from central South Dakota into
eastern parts of Nebraska and Kansas. The warm front will
gradually shift east/northeast tonight in concert with a migratory
cyclone tracking across North Dakota. Some vertical mixing
associated with a nocturnal LLJ will promote stronger surface
winds than last night, which should limit the potential for
widespread fog development. Model guidance does does hint at some
fog formation late tonight/early Friday over southeast Nebraska
into southwest Iowa where surface winds will be a bit lighter.
Friday, the mid-level ridge over the north-central U.S. will be
temporarily dampened by a short-wave trough translating along the
International Border. This disturbance will be associated with a
surface cold front which will advance southeast into the mid
Missouri Valley. Since this boundary will not reach northeast
Nebraska until afternoon, seasonably warm temperatures and breezy
conditions are expected across much of the forecast area.
Currently, we are forecasting highs in the lower 80s which will be
close to the record values of 84, 84, and 85 at Omaha, Lincoln,
and Norfolk, respectively.
The cold front will move slowly south through the area Friday
night and Saturday with highs in the mid to upper 70s Saturday
afternoon over southeast Nebraska and southwest Iowa. We will see
cooler temperatures areawide on Sunday as the cold front stalls
across Kansas and Missouri.
.LONG TERM...(Sunday night through Thursday)

Monday and Tuesday, 12z medium-range guidance is now in much
better agreement in the timing and amplitude of a short-wave
trough which will translate from the northern High Plains into
upper Great Lakes. The associated surface low will pass to our
north with the trailing cold front moving into the mid Missouri
Valley on Monday, before stalling over eastern Kansas and western
Missouri Tuesday. Ahead of the front, well-above-normal temperatures
and gusty winds are expected with cooler conditions anticipated by
Tuesday.
The stalled surface front may lift north into the area toward the
middle of the upcoming work week as southerly low-level winds
strengthen ahead of an upper trough moving through the Interior
West. This pattern evolution will support an increasing chance of
showers and thunderstorms in the Tuesday night to Thursday time

1007 PM EDT Thu Oct 27 2016
.SYNOPSIS...
A cold front will settle south into NC late tonight through early
Fri. High pressure will follow and extend across the Carolinas
through the weekend.
&&
.NEAR TERM /TONIGHT/...
As of 1000 PM Thursday...
00Z RAOB and VWP data across the Carolinas this evening depict
pronounced veering of the wind in the lowest 500 mb, and implied WAA
and contribution to QG forcing for ascent. This WAA regime is
occurring on the SRN periphery of a pronounced shortwave trough
moving E across far SERN Ontario, whose focused height falls aloft
will continue to pass well N of central NC. Within the WAA regime, a
narrow ribbon of low-mid level moisture and associated transport,
capped above by an inversion around 12 k ft, and sampled well by
both the RNK and GSO RAOBs, will progress steadily E across central
NC during the next several hours, then offshore by 12Z.
This moist axis will maintain a chance of a few (widely scattered)
showers over the NE Piedmont and Coastal Plain through around 06Z,
with dry conditions otherwise and elsewhere. Since the surface cold
front accompanying the aforementioned shortwave trough remained
along and west of the Appalachians from ERN WV to ERN TN and NRN AL
at 02Z --and it will likely not settle into even the NRN NC Piedmont
until around daybreak-- it will be a relatively mild night. Lows
mainly in the middle 50s to lower 60s.
A steady light SSW surface wind will limit the potential for fog
development tonight, despite otherwise favorable conditions that
include clearing behind the aforementioned low-mid level moist axis
and seasonably high pre-frontal surface dewpoints around 60 degrees.
&&
.SHORT TERM /FRIDAY THROUGH FRIDAY NIGHT/...
As of 245 PM Thursday...
In the wake of the trough crossing the area today, the cold front
will settle south into SC as brief cold advection pushes
thicknesses down to around 1360. This will offset what is
otherwise full heating with high pressure building across the
central Appalachians. Prefer a blend of MOS values here - 69 to 76
from northeast to southwest.
High pressure will settle overhead Friday night, yielding optimal
radiational cooling conditions. Most of the blended guidance looks
a little too warm given thicknesses and cooling potential, so
will opt for MOS values here as well - 44 to 49.
&&
.LONG TERM /SATURDAY THROUGH THURSDAY/...
As of 245 PM Thursday...
Primary storm track will follow the main belt of westerlies that
will shift northward along the US/Canada border as upper level ridge
over the Central Plains expands eastward into the Southeast US.
This will favor a continuation of dry conditions with temperatures
well-above normal, averaging a good 7 to 12 degrees above normal
through next week, potentially peaking Sunday with the potential for
near record warmth in the lower to mid 80s possible in advance of a
dry and weak back-door cold front late Sunday night. After a brief
cool down to more seasonable temps on Monday, temperatures will
quickly warm back into the mid 70s to lower 80s by Wednesday.
Significant discrepancies begin to show up in both the probabilistic
and deterministic model guidance late next week, with the GFS
retrograding the upper level ridge far enough west to allow a back-
door cold front to push south into the area late Thursday, while the
ECMWF keeps the upper ridge in place over the region and keeps the
front north of the area.
&&
.AVIATION /00Z Friday through Tuesday/...
As of 815 PM Thursday...
VFR conditions will dominate for the next several hours and into the
overnight hours at all sites, although a period of sub-VFR
conditions is possible 08z-12z. A band of showers currently crossing
northern portions of the forecast area may bring a brief shower to
RDU/RWI through 04z, although cigs and vsbys should remain mostly
VFR. Winds will remain light from the SW at speeds under 7 kts
through much of the night, ahead of a cold front dropping into the
area from the NW. Lingering low level moisture and light winds ahead
of this front will bring about a chance for IFR vsbys and low
shallow stratus late tonight. Models are quite variable in depicting
any such sub-VFR conditions, leading to lower than usual confidence.
The GFS favors late-night/early-morning stratus/fog at RDU/RWI,
while the HRRR hints at such conditions confined to the INT/GSO
areas, and the NAM indicates just MVFR fog at all locations. Based
on the steady stream of mid and high clouds heading into the area
from the WNW which could inhibit radiational cooling and limit fog
development, will lean toward the HRRR, with IFR conditions
restricted to INT/GSO, as the front is only expected to drop into
the VA border counties toward daybreak. All clouds will clear out
Fri morning, with VFR conditions highly likely thereafter, and
surface winds becoming light from the north as the front drops
through.
Looking beyond 18z Fri, high pressure will build in Fri through Sun,
leading to a high confidence in VFR conditions and light surface
winds, although there is a small chance of shallow fog Sat and Sun
mornings near dawn, especially near bodies of water. A weak front
will drop through late Sun night/Mon morning, which may bring a
period of MVFR cigs Mon into Mon night, but this risk appears low at
this time. -GIH

.SHORT TERM...(Today and tonight)
Issued at 309 AM CDT Fri Oct 28 2016
The main impactful weather concerns for today are on breezy
southerly winds that could gust to around 35 mph at times in open
areas. Focus then turns to rain chances late Saturday afternoon into
Saturday night.
Breezy south to southwest winds develop across the region today in
response to a tightening pressure gradient ahead of an approaching
cold front. The main question for today is how deeply will we mix.
This will have a direct impact on how windy and warm we may get
today. RAP and NAM Forecast soundings across southeast Minnesota,
northeast Iowa, and portions of southwest Wisconsin suggest we will
mix to just above 950 mb, maybe as deep as 925 mb. This should
result in high temperatures climbing into the mid to upper 60s, and
possibly to around 70 in southern areas. It will really depend on
how much sunshine is seen today. It appears areas along and west of
the Mississippi River will see some filtered sunshine at times
through high clouds. Sustained winds today will likely be in the 18
to 23 mph range, with gusts to around 35 mph possible in the open
areas of southeast Minnesota and northeast Iowa. If we mix just a
little deeper, closer to 925 mb, we could see a few gusts closer to
40 mph. Further to the northeast across central into northern
Wisconsin, thicker cloud cover should limit mixing and keep high
temperatures in the lower 60s, still very pleasant for this time of
year.
The surface front edges across the area late tonight into Saturday
morning and looks to stall out across portions of central Iowa
through northern Illinois. Winds will switch to the north in the
wake of the front but will be on the light side. Considerable
cloudiness will linger across the area in the wake of the front.
.LONG TERM...(Saturday through Thursday)
Issued at 309 AM CDT Fri Oct 28 2016
A shortwave trough will slide through the region late Saturday
afternoon into Saturday night and interact with the front.
Frontogenesis looks to increase across the region mainly in the 900 to
600 mb layer. This will result in a period of light rain, but the
concern is exactly where. Forecast models paint light rain across
much of the forecast area. The NAM is showing more concentrated
area of light rain positioned mainly along and south of the
Interstate 90 corridor. The GFS shows a broader swath of rain and
meanders it south across the region. The bottom line is that all of
the models are indicating rain across much of the area, it`s really
a matter of where the best frontogenesis zone sets up for a more
concentrated band of light rain. Forecast models have slowed the
arrival of the rain down slightly and has shifted the axis of rain
slightly south. Will lean toward a model consensus blend for rain
chances but if trends continue we will likely need to increase these
chances along and south of Interstate 90.
After a quiet day on Sunday, another windy and potentially milder
day is in store for the region on Monday. Again, cloud cover and how
deeply we can mix will be a big player in wind speeds and high
temperatures. There is the potential for some light rain across far
northern Wisconsin on Monday as a shortwave trough moves in from the
northern plains. Temperatures then remain on the milder side for
early November as we go through next week with west to southwest
flow aloft in place with highs in the 50s to around 60. The next
chance for rain arrives late Tuesday into Wednesday as a weak
boundary sets up across the region. Considerable uncertainty in
the forecast models regarding these rain chances so it`s difficult
to nail down any specific details on timing and rainfall amounts
at this time. Weak upper level ridging looks to remain in place
across much of the conus through the end of next week with no
major cool downs on the immediate horizon.

The low clouds have continued to make slow progress to the
northeast and now look like they will clear both airports
overnight. The 28.03Z RAP looks to have the best handle on these
clouds and takes them out of both sites right around 09Z.
Satellite imagery shows lots of high clouds in place and these
will keep streaming in overnight and should limit any fog
potential to primarily MVFR at KRST with just a small potential
for a dip to IFR. The winds still look to be rather gusty Friday
ahead of the approaching cold front, but the depth of mixing will
be shallow enough to keep these gusts around 20 knots for KLSE and
in the 25 to 30 knot range for KRST until the mixing gets cut off
about sunset Friday evening.

Fog will be the forecast challenge through the early morning hours
of Friday. The 07Z RAP and HRRR are indicating patchy fog
primarily in eastern and north central areas, supported well with
current obs. Increasing west/northwest winds should limit
widespread dense fog.
For the rest of today, surface low pressure and a trailing cold

seasonably warm weather is expected with highs nearing 20 degrees
above average in southern and central areas. Breezy northwesterly
winds will accompany the surface low as it scoots eastward.
.LONG TERM...(Saturday through Thursday)
Issued at 408 AM CDT Fri Oct 28 2016
A return to seasonable temperatures marks the start of the long term
forecast.
The 00Z ensemble and deterministic models are projecting progressive
flow aloft through the period, as a series of mid/upper level
troughs propagate across North Dakota.
On Saturday high pressure moves in at the surface; though aloft a
sagging low pressure system over the eastern Northwest Territories
will bring cooler Canadian air into the state. Highs will be in the
40s. The flow will also split on Saturday, as a short wave
transverses the northern plains creating favorable chances for rain
across the south. Much of the rain will stay in South Dakota.
The next trough is projected to start moving into the state Sunday
night through Monday, eventually closing over southern Manitoba.
Widespread chances for rain is in the forecast. Another trough is
depicted in the ensemble and deterministic models towards the end of

311 AM CDT Fri Oct 28 2016
.SHORT TERM.../Today/
Issued at 310 AM CDT Fri Oct 28 2016
The primary sensible weather concerns today will be temperatures and
winds. A short wave, associated forcing and surface low pressure
reflection will ride the nose of the jet across the northern Plains
into the Great Lakes by 00z. Warm advection will be fairly strong
through the morning until the thermal ridge reaches Iowa by early
afternoon, but this lift will be moisture starved with only mid and
high level cloudiness. The 07z surface analysis shows low level
moisture has returned to eastern KS with stratus and fog development
and most high resolution models suggest this will reach southern and
possibly central IA before dissipating and lifting by noontime.
The 07z analysis also shows a warm front NNW-SSE across Iowa,
roughly from Spencer through Des Moines to Keokuk. This should lift
north and east through the state as the surface low reaches
northwest MN by 18z bringing much of the forecast area into the warm
sector. This will boost highs well through the 70s in most areas,
and possibly touching 80 in spots from Des Moines toward the MO
River. This will be quite warm but still several degrees off
records. Mixing to reach these levels would suggest a depth to
around 600m with soundings showing a brief period of wind gusts to
35 mph or more. Confidence in both temps and wind gusts is only
medium however as the NAM is less aggressive with mixing due to
effects from low level moisture, while recent HRRR and RAP runs
suggest even higher. Thus have raised wind gusts this afternoon, but
this will need to be monitored as it could go in either direction.
.LONG TERM.../Tonight through Thursday/
Issued at 310 AM CDT Fri Oct 28 2016
Tonight through Tuesday...Confidence Medium to High...Few changes
expected in the near term through Tuesday. Cool front expected to
move south into north central Iowa overnight tonight and
temporarily take unseasonably warm air with it for the moment
across the north. Tomorrow...per previous discussions an area of
precipitation will develop well behind the boundary over Wyoming
then moving east toward Iowa by late Saturday afternoon and
evening. This is associated with both an upper H850 to H700
boundary as well as a short wave over Idaho /Montana at 06z
Friday. This will result in sufficient lift to produce an area of
light rain that will translate east southeast into northern Iowa
to eastern Iowa by 12z Sunday. Over the past several days the
NAM/GFS have come around to the Euro solution of slowing the cool
front down enough that from about the I80 corridor south
temperatures will recover enough to bring a warm day to much of
southern Iowa...but not quite as warm as today. High pressure will
settle across the region on Sunday with pleasant afternoon
conditions...and more fall like readings in the 50s and 60s. With
the active weather pattern continuing over the CONUS...another
vigorous system will be hitting the west Coast. Aloft a western
H500 mb trough will induce ridging over the Rockies and
Plains...lifting heights and thickness values. By Monday lee side
troughing will quickly result in another surface low over the
western Dakotas. This will keep a warm front and precipitation
well north of Iowa... leaving us in the warm sector. Another warm
and breezy day is expected...with high confidence again that
Monday will see highs well into the 70s. Once the Monday system
passes east...temperatures will again cool off into Tuesday. The
cool front is expected to stall south of the state and become
stationary by Tuesday evening.
Tuesday Night through Thursday...Confidence Medium...Models
coming into better agreement with regard to return flow and
potential for showers and elevated convection overnight Tuesday
night into Wednesday. This will be along a boundary that will
again move southeast of the area as low pressure tracks northeast.
The chances for convection will continue into Wednesday along the
receding boundary finally exiting by Thursday morning as high
pressure builds across the state. A return of cooler temperatures
will accompany the front.

.AVIATION.../For the 06Z TAFS through 06Z Friday night/

VFR cigs expected through the forecast period for the most part.
There is some potential for patchy fog but mixing should be strong
enough that vsbys will not drop much. There is also some hint that
stratus will move back in but confidence is low that anything more
than a sct low deck will develop. Warm advection moves in on Friday
setting up a strong inversion but winds in this shallow mixed layer
are 25 to 40 kts so it will become windy in the late

Dry and warmer weather is expected through Saturday as the Ohio
Valley remains under the influence of high pressure. A cold front
will drift into the region on Sunday bringing clouds and scattered
showers before stalling then lifting back north on Monday. Warm and
dry conditions will resume for the first half of next week with
cooler weather to follow late week as a cold front brings rain
showers to the region.
&&
.NEAR TERM /Today/...
Issued at 331 AM EDT Fri Oct 28 2016
Low stratus lingers in pockets generally focused over the northeast
half of the forecast area with mid level clouds above early this
morning. Where skies had cleared patchy fog had developed as
well...especially over the Wabash Valley. 07Z temps ranged from the
upper 30s to mid 40s.
A dry and warmer day coming for central Indiana as high pressure
centered over the region this morning moves away to the east with
back side southerly flow developing. Primary focus early this
morning is the gradual diminishing of the lower stratus. RAP 925mb
RH progs and sounding data indicating the inversion may take until
mid morning to completely erode over far northeast portions of the
forecast area. Likewise patchy fog will likely take until 13 or 14Z
to completely diminish.
Once all of the stratus and fog has dissipated...expect a really
nice autumn day with plenty of sunshine and just some passing high
clouds. The arrival of a low level jet into the western Great Lakes
by late day combined with a tightening surface pressure gradient
across the Midwest will support increasing southerly flow by late
day. Most gusts however should hold off until tonight as the low
level jet passes by to the north.
Temps...warm advection will commence with the southerly flow
developing later today. Trended at or just above warmer MAVMOS
guidance for highs in the mid and upper 60s.
&&
.SHORT TERM /Tonight through Sunday Night/...
Issued at 331 AM EDT Fri Oct 28 2016
Forecast challenges focus on precip chances Sunday and temps
throughout the forecast period. Wavy upper flow highlighted by
ridging aloft will promote warm and dry weather through much of the
short term. The passage of a weak wave aloft and an associated cold
front moving into the region on Sunday will provide a brief period
of cooler and potentially unsettled weather before ridging aloft
reestablishes for early next week.
The aforementioned cold front will sag into the lower Great Lakes on
Saturday but will be unable to move any further south into central
Indiana...blocked by ridging aloft and at the surface focused over
the Ohio and Tennessee Valleys. With the core of the low level jet
over the Great Lakes and tight gradient between the cold front to
the north and the surface ridge to the south...expect warm and
breezy southwest winds Saturday.
The approach of the upper wave into the region from the west late
Saturday night and early Sunday will buckle heights aloft and enable
the frontal boundary to make a more concerted push south into
northern portions of the forecast area. The combination of forcing
aloft and weak isentropic lift will likely be enough to generate
scattered light showers in the vicinity of the frontal boundary on
Sunday...focused primarily over areas near and north of I-70 before
transitioning into eastern Indiana by the afternoon as the wave
aloft moves east. Anticipate a fairly cloudy day for most of the
area except perhaps the far south as model soundings favor moisture
becoming trapped beneath a sharp inversion.
The boundary will become quasi-stationary over the forecast area by
Sunday evening before lifting back north towards daybreak Monday in
response to strong low pressure tracking into the Dakotas. Despite
the front remaining in the area Sunday night...lack of appreciable
forcing aloft with the return of upper ridging will limit any
rainfall. The inversion however will only gradually weaken with
cloud cover slow to diminish as well through the night.
Temps...low level thermals support a general model blend for highs
both Saturday and Sunday. Expect upper 70s to potentially lower 80s
for Saturday from north to south. The clouds and the front will keep
temps cooler on Sunday for much of the area...ranging from the mid
60s north to mid 70s far south. Lows will remain primarily in the
50s through the period.
&&
.LONG TERM /Monday Through Thursday/...
Issued at 224 AM EDT Fri Oct 28 2016
Models are close enough that the SuperBlend initialization was
accepted for most items.
Upper ridging will keep central Indiana warm and most of the area
dry until mid week, when an upper trough pushes into the area from
the northwest. Models still differ a bit on timing, but the
uncertainty that far out leads to sticking with the model blend.
Temperatures will remain well above normal into mid week, then cool
some (but still above average) for Thursday.

temperatures are much lower due to the fog. Adjusted clouds and
temperatures somewhat. However...based on sounding, do expect
maximum temperature forecast today to be in the ballpark enough
not to change at this time although temperatures may be a degree
or two cooler in some locations due to the sustained east flow and
lingering clouds. Showers continue to develop near the coast and
some of these may move inland later this afternoon...especially
south. HRRR and NSSL showing some sea- breeze activity this
afternoon...so maintained rain chances. No other changes needed at
this time. Products have been updated. No change to the marine
package.
&&
.PREVIOUS DISCUSSION... /Issued 629 AM CDT Fri Oct 28 2016/
DISCUSSION...Please see the discussion below for more details.
AVIATION...Patchy MVFR/IFR conditions across mainly northern
areas will dissipate by 14-15Z this morning. Otherwise, most areas
will remain at VFR through the day. Isolated showers will be
possible today, mainly between 17Z and 22Z across the southern
Coastal Bend. More widespread MVFR/IFR conditions are expected to
develop after 08Z Saturday across inland areas, especially
Victoria and Alice.
PREVIOUS DISCUSSION... /Issued 419 AM CDT Fri Oct 28 2016/
SHORT TERM (Today through Saturday)...Sufficiently deep boundary
layer moisture, steep low level lapse rates, and boundary layer
convergence will produce isolated showers across portions of the
CWA today. This is in line with the past few runs of the SREF and
HRRR. Dry and capped air aloft should mostly limit activity to
just showers. Moisture advection will continue through Saturday
as a mid/upper low approaches from the east on Saturday. The
result will be PWATs rising to around 1.5 inches across the
Coastal Bend and adjacent waters by Saturday. Will therefore
maintain slight chance to low chance PoPs across mainly the
southern and eastern areas on Saturday. Aftn highs will be
tempered slightly by the increased moisture but will still remain
above normal through the pd.
LONG TERM (Saturday Night through Thursday)...Models have
consistently shown a mid/upper level high pressure system tracking
east across TX Sat night through Mon. This will allow increasing low
level moisture to advect across the gulf waters and into S TX. By
Tue, the upper level high pressure is progged to be located across
the NE gulf while a long wave trough swings across the western U.S.
This allows moisture in the mid and upper levels to move across the
region from the Pac. This could lead to PWATs of near 2 inches by
Tue. In a nutshell, waves of moisture are progged to approach S TX
during the extended with rain chances expected to be the highest Tue
and Wed. The increased moisture/clouds will result in slightly
cooler mx temps and warmer mn temps through the middle of next week,
but remaining above normal. Winds will generally be onshore through
the period with moderate speeds at times. Models also continue to
show longer swell periods and elevated seas Sun-Wed. This may lead
to minor tidal overflow and an increased threat of rip currents at
times through the extended period.
MARINE... A moderate gradient due to broad high pressure
anchored across the Deep South and broad low pressure in the
Caribbean will persist through the weekend. These conditions will
maintain persistent 8-9 second period swells of 3-5 ft to affect
the coastal waters through Saturday. The result will be a moderate
to high risk of rip currents along with minor tidal overflow. For
now, it appears that tides will remain below 2 ft MSL. However,
the wave run-up due to these long period swells may warrant a
coastal flood advisory for this weekend mainly from Port A
southward. Will continue to monitor. At the minimum, a rip
current statement will be needed on Saturday given the high risk
of rip currents.

AREA FORECAST DISCUSSION
National Weather Service Des Moines IA
630 AM CDT Fri Oct 28 2016
.SHORT TERM.../Today/
Issued at 310 AM CDT Fri Oct 28 2016
The primary sensible weather concerns today will be temperatures and
winds. A short wave, associated forcing and surface low pressure
reflection will ride the nose of the jet across the northern Plains
into the Great Lakes by 00z. Warm advection will be fairly strong
through the morning until the thermal ridge reaches Iowa by early
afternoon, but this lift will be moisture starved with only mid and
high level cloudiness. The 07z surface analysis shows low level
moisture has returned to eastern KS with stratus and fog development
and most high resolution models suggest this will reach southern and
possibly central IA before dissipating and lifting by noontime.
The 07z analysis also shows a warm front NNW-SSE across Iowa,
roughly from Spencer through Des Moines to Keokuk. This should lift
north and east through the state as the surface low reaches
northwest MN by 18z bringing much of the forecast area into the warm
sector. This will boost highs well through the 70s in most areas,
and possibly touching 80 in spots from Des Moines toward the MO
River. This will be quite warm but still several degrees off
records. Mixing to reach these levels would suggest a depth to
around 600m with soundings showing a brief period of wind gusts to
35 mph or more. Confidence in both temps and wind gusts is only
medium however as the NAM is less aggressive with mixing due to
effects from low level moisture, while recent HRRR and RAP runs
suggest even higher. Thus have raised wind gusts this afternoon, but
this will need to be monitored as it could go in either direction.
.LONG TERM.../Tonight through Thursday/
Issued at 310 AM CDT Fri Oct 28 2016
Tonight through Tuesday...Confidence Medium to High...Few changes
expected in the near term through Tuesday. Cool front expected to
move south into north central Iowa overnight tonight and
temporarily take unseasonably warm air with it for the moment
across the north. Tomorrow...per previous discussions an area of
precipitation will develop well behind the boundary over Wyoming
then moving east toward Iowa by late Saturday afternoon and
evening. This is associated with both an upper H850 to H700
boundary as well as a short wave over Idaho /Montana at 06z
Friday. This will result in sufficient lift to produce an area of
light rain that will translate east southeast into northern Iowa
to eastern Iowa by 12z Sunday. Over the past several days the
NAM/GFS have come around to the Euro solution of slowing the cool
front down enough that from about the I80 corridor south
temperatures will recover enough to bring a warm day to much of
southern Iowa...but not quite as warm as today. High pressure will
settle across the region on Sunday with pleasant afternoon
conditions...and more fall like readings in the 50s and 60s. With
the active weather pattern continuing over the CONUS...another
vigorous system will be hitting the west Coast. Aloft a western
H500 mb trough will induce ridging over the Rockies and
Plains...lifting heights and thickness values. By Monday lee side
troughing will quickly result in another surface low over the
western Dakotas. This will keep a warm front and precipitation
well north of Iowa... leaving us in the warm sector. Another warm
and breezy day is expected...with high confidence again that
Monday will see highs well into the 70s. Once the Monday system
passes east...temperatures will again cool off into Tuesday. The
cool front is expected to stall south of the state and become
stationary by Tuesday evening.
Tuesday Night through Thursday...Confidence Medium...Models
coming into better agreement with regard to return flow and
potential for showers and elevated convection overnight Tuesday
night into Wednesday. This will be along a boundary that will
again move southeast of the area as low pressure tracks northeast.
The chances for convection will continue into Wednesday along the
receding boundary finally exiting by Thursday morning as high
pressure builds across the state. A return of cooler temperatures
will accompany the front.

.AVIATION.../For the 12Z TAFS through 12Z Saturday morning/
Issued at 629 AM CDT Fri Oct 28 2016
LIFR conditions should affect the KMCW area for another few hours
before lifting into VFR area wide with nothing beyond high
cloudiness. Winds will become quite gusty for a brief period this
afternoon with some gusts 30+kts. Strong SW winds just off the
surface may lead to LLWS near KFOD briefly early this morning, and
then again into tonight toward KOTM.

.SYNOPSIS...
Fair and warm conditions will continue over the weekend into next
week. A weak dry front moving through late Sunday/early Monday
will reinforce dry conditions early to mid next week.
&&
.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
Current weather analysis indicates a weak frontal boundary slowly
pushing through the CWA. Drier air will be filtering into the
area into the evening. No precip expected due to the dry
conditions. Surface winds shifting out of the northwest. The main
change with this air mass will be the additional drier air
pushing into the area. Not much difference in regards to
temperatures. Skies mostly clear through tonight. Some patchy fog
may be found near area rivers during the early morning hours.
Overnight lows in the mid 50s.
&&
.SHORT TERM /6 AM SATURDAY MORNING THROUGH SUNDAY NIGHT/...
Dry and mild weather continues over the weekend with surface high
pressure centered over the forecast area Saturday then shifting
offshore by Sunday allowing a southerly flow to develop over the
region. An upper-level ridge will move over the area Saturday
then the 500 mb flow flattens Sunday in advance of an approaching
shortwave trough which will pass by to our north off the Mid-
Atlantic coast Sunday evening allowing a weak backdoor front to
push into the region. Moisture again will be limited with this
front and no precipitation is expected.
High temperatures will continue to be some 10-15 degrees above
normal this period with max temperatures in the mid to possibly
upper 80s and approach record highs. Low temperatures will also
remain mild in the mid 50s.
&&
.LONG TERM /MONDAY THROUGH FRIDAY/...
Surface high pressure will remain entrenched over the region
through mid week while a building upper ridge over the
southeastern states will ensure continued warm and dry conditions.
Temperatures will remain above normal with highs in the 80s and
lows in the 50s.
Late in the forecast period the medium-range models show the
upper ridge over the southeastern states retrograding westward
allowing for an amplified upper trough to dig down the east coast
but there are some differences in timing between the latest GFS
and previous ECWMF leading to low confidence in possibility of
precipitation at this point. Both models hinting at a closed upper
low developing over the Southeast Friday. Latest MEX guidance
showing chance pops for late Friday. Given current uncertainties,
for now will lean towards a low pop for Friday.
&&
.AVIATION /22Z FRIDAY THROUGH WEDNESDAY/...
A weak dry cold front will continue pushing south through the area
tonight with dry high pressure returning for Saturday. Mostly
clear skies and light/calm winds are expected at the terminals
through the overnight period. The HRRR shows LIFR conditions
developing in the eastern portion of the forecast area towards
daybreak Saturday morning which would affect the OGB terminal. The
local radiation fog tool which incorporates the crossover
temperature shows MVFR fog at CAE/CUB and LIFR at OGB and AGS
toward daybreak. This appears reasonable so have continued with
restrictions at all of the terminals between 11 and 13Z. Expect
rapid improvement by 13Z with diurnal heating/mixing.

537 PM EDT Fri Oct 28 2016
.SYNOPSIS...
Dry weather can be expected today and Saturday as high pressure
builds across the area. Unseasonably warm conditions will return
by Saturday with highs in the 60s to mid 70s. A cold front will
bring a chance of showers to the northern mountains Saturday
night and to the rest of the area on Sunday.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
The sunshine will only help temps get so high with 8H temps sub-
zero to start the day. Mixing does get 8H temps to +2 or 4C. Thus
maxes will likely be in the m40s N/NE but could get in the m-u50s
in the far srn sections. Winds will probably still be breezy in
the morning and early aftn, but the sfc high builds into wrn PA by
the end of the afternoon and the wind should diminish late in the
day in the W.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY NIGHT/...
Friday night will be mainly clear with light winds under high
pressure. Mild weather will return on Saturday with 850 mb
temperatures forecast to rise back into the +10 to +13C range -
allowing surface temperatures to climb into the 60s with l70s in
the south. The next front approaching from the north may trigger a
few showers over the northern mountains late in the day. The front
will stall for a short time as it enters PA as a sfc wave forms
along the front back in the midwest. The upper short wave trough
sliding straight east over the area will help to shove the front
slightly to the south Sat Night. But the front won`t pass through
most of the CWA until late in the day Sunday.
&&
.LONG TERM /SUNDAY THROUGH FRIDAY/...
The start of the long term period will feature a progressive and
relatively weak upper shortwave and associated sfc cold front that
will move through the region mainly during the daylight hours
on Sunday...exiting the southern tier counties of the state Sunday
evening.
A brief cooldown will occur monday (under NW flow aloft with a
1026mb sfc high sliding by across upstate NY and SERN canada) with
perhaps a few morning light showers or flurries across the mtns NE
of KIPT thanks to shallow moisture streaming SE from Lake Ontario
and zero C wet bulb temps within 1 kft agl.
Warmer air floods into the region from the west later Monday night
into the midweek period with generally nothing more than periods
of mid/high-level clouds and maybe a few light showers brushing
the nrn tier of the state Tuesday as a flat shortwave aloft races
ENE across the Lower Great Lakes region.
Disjointed...nrn and southern stream waves moving through the Mid
Miss Valley and Lower Great Lakes regions Thursday/Thursday night
could bring a few showers to the region. Prior to this later week
cfropa...high temps Wed and Thursday should surge well into the
60s and lower 70s in many locations Wednesday. Temps could be
warmer than currently forecast Thursday in the SE zones if timing
on the cfropa is a bit slower.
The upper level ridge across the eastern U.S. during the early to
mid week period will retrograde to the Rockies and High Plains
late in the week and next weekend...allowing the upper flow in
the east to veer to the NW...with one or two chunks of nrn stream
energy bringing a few cold fronts and isolated to scattered
showers.
Overall, the upcoming week will be milder than normal and
reasonably quiet with 7 day QPF likely under 0.25...and almost
definitely under 0.50 inch in all areas.
&&
.AVIATION /22Z FRIDAY THROUGH WEDNESDAY/...
High pressure over the region will provide fair weather tonight
across Central Pa with just enough of a breeze to preclude any fog
issues. SREF and model RH profiles point toward a near certainty
of VFR conditions tonight.
A cold front will approach from the north on Saturday, bringing
the chance of showers and MVFR cigs to KBFD during the PM hours.
Will also be expecting increasingly gusty WSW winds preceding the
front. A combination of bufkit soundings and HRRR output supports
gusts during the afternoon to near 30kts at KBFD, near 25kts at
KJST and generally under 20kts elsewhere.
Outlook...
Sun...Showers/low cigs possible, esp N and W.
Mon-Wed...No sig wx expected.

704 PM EDT Fri Oct 28 2016
.SYNOPSIS...
Surface high pressure over the region will build east to the Mid
Atlantic by Saturday morning. A southerly flow will develop on the
back side of this retreating high offering a warming trend. A cold
front will push through the area on Sunday, bringing with it a
chance of showers. Slightly cooler air will briefly settle in
behind the front before another warm up for midweek.
&&
.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
Surface high pressure over the region will push off to the east,
becoming centered over the Mid Atlantic by Saturday morning. At the
same time a mid level ridge will build into the region. This will
allow high level clouds to drift in from the northwest. Lows will be
milder tonight due to the clouds and southerly winds that stay up at
speeds of 5 to 10 mph. Lows are expected to run 8 to 10 degrees
above normal, ranging from the upper 40s east to the lower/middle
50s west.
&&
.SHORT TERM /6 AM SATURDAY MORNING THROUGH SUNDAY NIGHT/...
Models solutions in general agreement with broad mid level
ridge extending north into the Ohio Valley Saturday with s/w
passing thru the Great Lakes Saturday night/Sunday, allowing a
surface cold front to drop south through the region. This setup will
bring an increase in the low level srly flow Saturday. In this WAA
pattern temperatures will warm up around 15 degrees above normal
with highs on Saturday ranging from the mid 70s north to near 80
south.
The cold front will slowly sag south into the southern Great Lakes
by Sunday morning and then south through ILN/s FA Sunday. Have
allowed for an increase in clouds and only a slight chance of a
shower far north toward sunrise Sunday. Mild lows expected in the
mid and upper 50s Saturday night.
As the front pushes into the area low level forcing and upper level
support will be maximized across the northern and central counties
during the day Sunday. Have high chance pops here mainly during the
afternoon. NAM appears overdone with instby and favor the marginal
instability that the GFS is showing. Given this marginal instby will
only mention slight chance of thunder.
High temperatures will show a good range from the lower 60s far nw
to the upper 60s far south.
The threat for precipitation will end quickly early Sunday evening.
Lows to range from the mid 40s north to the mid 50s far south.
&&
.LONG TERM /MONDAY THROUGH FRIDAY/...
High pressure will push to the east on Monday and southerly flow
will develop. This will allow for several days of well above normal
temperatures. Wind gusts will pick up for Tuesday with some gusts
around 20 to 30 mph. Models have come into good agreement on
keeping a dry forecast on Wednesday and therefore kept Wednesday dry.
A cold front will move through on Thursday and bring rain showers to
the region and slightly cooler weather. Dry conditions are expected
to return by Friday.
&&
.AVIATION /00Z SATURDAY THROUGH WEDNESDAY/...
High pressure has already moved east of the area this evening
allowing a return of southerly winds. Overnight into Saturday
morning a strengthening LLJ will push east into the region
bringing 40 kt winds near 900 mb. This is shown on both the NAM
and GFS with the core of the jet stretching along and north of
Interstate 71. The jet will then begin to weaken as the sunrises
thanks to a weakening low level pressure gradient. The jet will
still be sustained around 30 kts though and with ample mixing
winds will be gusty at times Saturday afternoon. The GFS is
showing wind gusts up to 25 kts possible (via momentum transfer)
while the NAM is showing closer to 20 kts with the RAP even
slightly weaker. Given the lack of clouds have leaned towards a
blend of the GFS/NAM solution. Saturday night winds will start to
decrease as daytime heating is lost. VFR through the issuance is
expected.
OUTLOOK...MVFR ceilings are possible on Sunday and Monday.

304 PM CDT Fri Oct 28 2016
.NEAR TERM /Now Through Saturday/...Water vapor satellite imagery
and RAP 500 mb height analysis show an upper level low translating
westward across the western Gulf of Mexico, while an upper level
ridge of high pressure meanwhile extends from west TX and eastward
across much of the Deep South. Plentiful deep layer subsidence and
dry air is in place across our area, with mostly sunny skies courtesy
of some afternoon cumulus and high level cirrus. Temperatures are
generally ranging in the lower to mid 80s, with readings even
approaching 90 around Greenville as of 3 PM CDT.
Upper level ridging will continue to stretch across the southern and
southeastern U.S. through Saturday, keeping a dry and subsident
airmass in place across our forecast area into Saturday afternoon.
POPs subsequently remain nil. There could be some patchy fog
formation across areas away from the immediate coast again late
tonight and early Saturday morning, though the latest SREF, NAM and
HRRR are not as optimistic on fog development vs. trends the past
couple of days. Lows tonight are forecast to range from the lower to
mid 50s across most inland locations to around 60 to the mid 60s
along the immediate coast and beaches. Highs Saturday should range
from the lower to mid 80s along the immediate coast to the mid to
upper 80s over the interior. /21
.SHORT TERM /Saturday night Through Monday night/...Upper level
ridging over the Plains and Midwest weakens some this weekend, though
not enough to make any impact as we stay warm and dry here across the
southern Gulf states through the weekend. High pressure at the
surface builds into the southeastern U.S., continuing our generally
light easterly winds, with a weak southerly component possible near
the coast during afternoon hours. High temperatures Sunday and Monday
will range from mid to upper 80s inland to low 80s along the coast.
Overnight lows will dip into the mid 50s inland and low 60s along the
coast each night. /49
.LONG TERM /Tuesday Through Friday/...Another upper level ridge
builds over the southeastern states early to mid next week as
troughing digs into the western CONUS. This ridge will remain over
the area for much of the week, maintaining strong mid to upper level
subsidence and thus warm and dry conditions across the forecast area.
Weather models do currently attempt to dig an upper level low into
the central Gulf states at the tail end of next week. However, plenty
of uncertainty remains at this time regarding the location, timing,
and potential impacts from said system.
Otherwise, expect above seasonal temperatures to continue next week,
with highs reaching the mid 80s inland to low 80s along the coast
each afternoon. Lows will dip into the mid and upper 50s inland to
around 60 along the coast each night. /49
&&
.MARINE...A surface ridge of high pressure will continue to extend
across the southeastern U.S. and the Central Gulf Coast region
through the middle of next week. This pattern will continue to
support a light to moderate easterly flow over our marine area
through Wednesday. Wind speeds may range within cautionary levels
well offshore late and night and in the morning through the weekend.
Seas should gradually subside through the weekend and into Monday.
