.DISCUSSION.../Tonight through Saturday/
Issued at 358 PM CST Sat Dec 10 2022
Forecast Highlights:
- Patchy widespread fog expected late tonight through Sunday morning
- Quiet and mainly Dry Sunday into Monday with mild temperatures
- Large system continues to signal more active weather, with mixed
ptypes and breezy/windy conditions late Monday through much of the
work week
Dreary and foggy conditions continued across Iowa throughout the
day, with patchy fog still being reported this afternoon over most
of the region, along with widespread stratus outside of some
clearing over parts of western Iowa. Drizzle continued mainly over
eastern and portions of central Iowa through much of this morning as
the upper level shortwave moved across the upper Midwest, though has
since ended. Temperatures largely due to the dominant cloud cover
has kept temperatures on the cooler side today with values in the
low to mid 30s north and in the upper 30s further south. Therefore
knocked highs down a few degrees to account for these trends. Model
soundings continue to overall highlight the potential for returning
patchy to locally dense fog tonight into Sunday morning. The NAM and
RAP soundings favor more saturation in the lowest half to 1
kilometer space with subsidence and light winds, though the GFS
keeps a drier column overall though other parameters looks
favorable. HREF guidance paints an area of relatively widespread fog
over much of the state, leaning with the more saturated solutions.
Will continue to include fog in the forecast into Sunday before
eventually dissipating later in the day. Use extra caution and take
it slow on the roads if traveling late tonight into Sunday. Stratus
looks to be a bit slower to move out tonight, especially east, which
could limit dense fog potential but cannot rule it out completely,
especially north. Overall, western Iowa could see some clearing this
evening while the rest of the state continues to see lingering cloud
cover. Temperatures are expected to be cooler in the upper teens
through the 20s tonight, as winds turn more northwesterly with weak
CAA bringing in cooler air.
With an narrow upper level ridge and associated surface high
pressure system pushing through behind the departing shortwave
trough Sunday, quiet and dry weather is expected. Low level flow
will remain northwesterly through the afternoon before shifting more
southerly, which will allow for mild temperatures with highs in the
30s north and in the low 40s further south. Cloud cover will largely
hang on over much of the state through the afternoon, before
clearing from southwest to northeast into the evening. Dry weather
should remain for the most part Monday, though increasing moisture
with the increasing southerly flow will quickly bring returning
cloud cover ahead of a large system expected to impact the region
over the following several days. Temperatures will remain mild in
the upper 30s north to mid 40s south.
A very strong upper level trough and developing low pushing out of
the Rockies Monday into Tuesday continues to signal a longer term
active weather period through much of the next work week. A longer
band of more widespread lift just ahead of the system with
increasing moisture looks to bring in increasing precipitation
chances Monday evening into Tuesday. Deterministic models continue
to generally remain in agreement on the general track of the system
, but again strength remains somewhat different as the GFS and Euro
favor a slower onset of precipitation not arriving until Tuesday,
though the NAM and Canadian models are more robust with an earlier
start Monday afternoon to evening in western Iowa. A much colder NAM
solution however paints a broad area of freezing rain Tuesday
morning into the afternoon suggesting ice accumulations down into
central Iowa, before switching over to rain. With warmer air more
favorable over the region from the rest of the model solutions, all
precipitation will more likely fall as rain throughout Tuesday
across the state. More efficient rain production continues to also
be evident with overall totals looking to range upwards of an inch
in parts of the state, though the strength differences among models
do introduce more uncertainty given the timing out ahead of the
system, as the GFS ensembles also indicate a wider range of
solutions in the most recent runs. Freezing rain cannot be ruled at
times Tuesday mainly over northern Iowa with minor ice accumulations
still looking possible. Gusty winds continue to look rather
concerning as NBM guidance in recent runs has favored stronger
values in the 30 to 40 mph range, isolated to 45 mph especially
north Tuesday as the tighter pressure gradient travels across the
state. Advisory potential continues to look more certain but will
have to continue and watch if the trend remains consistent in the
coming days, as adjustment are expected to occur.
Into Wednesday as cooler air moves in, a transition mainly to a
rain/snow mix to snow is expected as the system lifts northeast,
largely impacting northern into portions of central Iowa while dry
air further south could allow for a short period of dry weather.
Specific snow totals are not known at this time, as this will
largely depend on the evolution on this system which continues to be
more uncertain this far out, but overall QPF totals looks rather
light in comparison to Tuesday`s projected values. Model guidance
continues to largely depict lingering snow over much of the state
Thursday as another system over the northeastern CONUS traveling
southwest blocks this large system from making a quicker exit, which
again looks to remain on the lower side for any additional
accumulations. Colder air behind the departing system Friday into
the weekend will allow for slightly cooler highs in the 20s to low
30s and lows mainly in the teens.

.AVIATION.../For the 00Z TAFS through 00Z Sunday evening/
Issued at 548 PM CST Sat Dec 10 2022
Clearing has moved into western Iowa but the cloud level steering
flow will shift from the west to the north/northwest overnight
which will eventually stop the eastward movement and draw even
more stratus south out of MN. KDSM/KFOD are the most likely to
have a few periods of VFR overnight otherwise MVFR/IFR cigs will
remain common. Some fog is possible in the clear regions which
could help fill in cigs as well overnight. Cigs should finally
break later Sunday afternoon if the eastward push is halted
tonight. The wind will be mostly light through the period.

...New UPDATE...
.UPDATE...
Issued at 725 PM CST Sat Dec 10 2022
Lowered the PoPs slightly across the Hill Country into the overnight
as the latest HRRR runs and the WRF-NSSL indicate that majority of
the activity develops along and east of the I-35 corridor where the
southward advancing front is expected to meet an ongoing region of
surface convergence extending from around I-35 into the Houston CWA.
SPC with the recent 01 UTC update of the Day 1 Convective Outlook
adjusted the marginal risk for tonight into coastal plains where the
models blossom the strongest convection in that region of stronger
surface convergence. WPC introduced a marginal risk as well this
afternoon for excessive rainfall for areas mainly along/east of I-35
and north of I-10 as these storms could be capable of producing a
quick 1 to 2 inches of rain with a few localized higher amounts
possible. Additionally, expanded patchy fog for across much of the
region into Sunday morning once the storms ends given lingering low-
level moisture levels with small dew point depressions and modest
post-frontal northerly winds.
&&
.SHORT TERM...
(Tonight through Sunday night)
Issued at 140 PM CST Sat Dec 10 2022
Synopsis/Mesoanalysis: 12 PM CST surface observations depict a slow-
moving cold front extending from the DFW Metroplex southwest into
the Edwards Plateau and Big Bend region. Warm, moist air is
entrenched to the south of the boundary, with most stations
reporting air temps in the mid 70s and dew points in the middle 60s.
Lower 80s have been noted over portions of the Coastal Plains.
Combined with low-level convergence along the slowly-progressing
frontal boundary, this air mass should help fuel scattered
thunderstorm development primarily to our north through the early
and middle afternoon hours. Augmented further by encroaching height
falls and DPVA affiliated with a shortwave trough currently centered
over Sonora, this activity should persist through the overnight
hours tonight, impacting locations primarily along and east of US
281 between midnight and daybreak Sunday morning. Despite a weak
northerly wind shift behind the departing front, warm and muggy
conditions will continue through the duration of the short term
period.
This Afternoon: Although the encroaching cold front will still be
situated to our north, showers and isolated thunderstorms can`t be
ruled out along and east of I-35 and I-37. Recent radar and
satellite trends have indicated several attempts at convective
initiation over this portion of the CWA, each being thwarted by a
capping inversion evident in the 12Z DRT RAOB and composite
soundings from AUS and SAT Intl Airports. Nevertheless, short term
model guidance suggests that the cap will erode with continued
surface heating, boundary layer moistening, and approaching pre-
frontal convergence through the late afternoon and early evening
hours, likely explaining the development of isolated convection just
ahead of the front in these solutions. Have thus accounted for this
potential in the afternoon update. Though certainly not widespread,
an isolated strong/severe storm is possible with this prefrontal
activity, with damaging wind gusts in excess of 60 MPH and hail
exceeding quarter size being the primary concerns.
Tonight: Anticipate a gradual increase in thunderstorm coverage
along/east of US 281 as the Sonora shortwave begins to overspread
the region. Like this afternoon, an isolated severe thunderstorm is
possible as this activity moves through. Given a predominantly
linear convective mode arising from parallel alignment between the
deep layer flow and advancing surface front, damaging wind gusts
reaching/exceeding 60 MPH will be the primary hazard in any severe
storm. While secondary to damaging winds, an isolated tornado can`t
be ruled out, particularly in any location where surface winds can
back out of the east-southeast. The Storm Prediction Center has thus
continued to carry a marginal (level 1/5) risk for severe weather
over the eastern CWA in light of this potential.
Tomorrow-Tomorrow Night: Conditions will remain muggy despite the
passage of the front. Many locations in the Coastal Plains, Winter
Garden, and portions of the I-35 corridor will see patchy fog
through the mid morning hours Sunday. Some of said fog could become
dense. Sunday highs should be a touch cooler than today with pesky
cloud cover sticking around into the late afternoon hours. Mild lows
and additional patchy fog will be possible Sunday night into early
Monday morning.
&&
.LONG TERM...
(Monday through Saturday)
Issued at 140 PM CST Sat Dec 10 2022
Southerly flow will return quickly on Monday as lee side surface
cyclogenesis develops ahead of a deep slow-moving low level trough
in the western CONUS. 850mb winds near 25-30 knots will lead to weak
ascent from warm-air advection. Forecast soundings show a decent
moist layer with adequate lapse rates for some isolated light rain
showers or perhaps some drizzle Monday afternoon. Will forecast 10-
20 PoPs for areas mainly east of the Highway 281 corridor. Things
should dry out for Monday night, but a Pacific front will move east
into the areas late Monday night into Tuesday morning and will bring
with it a chance for deeper convection. Should see a decent coverage
of showers and thunderstorms along and just behind this frontal
boundary for areas mainly north of a Kerrville to New Braunfels to
Cuero line. The best areas of forcing will be well to our north and
therefore not expecting much in the way of strong storms or heavy
rainfall from this activity. Rainfall amounts will generally average
less than a quarter of an inch.
Things will dry out Tuesday night with a dry forecast then expected
for the remainder of the long-term forecast period. Temperatures in
the extended will begin warm with highs in the upper 60s to near 80
on Monday and Tuesday. Should see slightly cooler temps behind the
front on Wednesday with highs in the 60s to near 70. A stronger
front is expected on Thursday and highs Friday and Saturday should
be in the upper 40s to 50s across the area. No rain is expected with
this front. Low temperatures in the period will follow the same
trend as the highs, starting off well above normal, before returning
back into the 30s to lower 40s Friday and Saturday.

.AVIATION...
(00Z TAFS)
Issued at 518 PM CST Sat Dec 10 2022
VFR flight conditions are in place this evening but expect for
conditions to deteriorate tonight into Sunday as a cold front will
advance into and across the region. Convection will be expected to
develop along and out advance of this boundary as it moves into the
region. The greatest storm potential for the I-35 TAF sites (KAUS,
KSAT, KSSF) where a solid line of convection is likely to develop
occurs by around the midnight hour and likely should continue for a
few hours. Activity then gradually wanes into the morning where I
have kept VCSH in the TAF package at those sites. MVFR ceilings and
visibility could accompany these storms. Flight conditions will
remain poor behind the storms through Sunday morning as lingering
low-level moisture will yield to patchy fog and early morning
ceilings as low as IFR to LIFR. Gradual improvement back to MVFR
levels can be expected into and through Sunday afternoon. The winds
become north to northeasterly behind the front but speeds should
remain below 10 knots.
As mentioned in the previous 18Z aviation discussion, no storms are
expected with the approaching front at KDRT. Additionally, expect
VFR conditions to continue through the majority of the night before
deteriorating with MVFR to IFR ceilings and visibility. Winds will
trend northeasterly at around 5 knots through Sunday morning before
becoming more variable as winds at KDRT will gradually shift more
east then east-southeasterly in direction during the afternoon.

646 PM EST Sat Dec 10 2022
.SHORT TERM...(This evening)
Issued at 318 PM EST SAT DEC 10 2022
Radar returns are starting to intensity across Upper Michigan as a
negatively-tilted trough continues its eastward propagation into the
Upper Midwest. Light snow is currently being reported across the
western half of the UP, and this is expected to become more
widespread over the next several hours during a period of
frontogenetical forcing. A lack of moisture and significant forcing
should limit snowfall amounts with projections still in the 1 to
2 inch range through the evening. Meanwhile, temperatures across
the area are generally in the upper 20s/low 30s with light and
variable winds.
.LONG TERM...(Sunday night through Saturday)
Issued at 409 PM EST SAT DEC 10 2022
Light snow continues to spread in this afternoon courtesy of weak
warm advection ahead of an approaching shortwave (currently analyzed
in RAP analyses over MN). ASOS sites across the far western UP and
in northwestern WI have been reporting visibility below a mile at
times, with an initial band moving through right now showing decent
reflectivity around 20 to 30dbz. So, while snow is for the most part
fairly light, with guidance continuing to come in below an inch for
most of the area, would not be surprised to see some higher embedded
totals closer to or even in excess of an inch especially across the
western UP. Snow largely tapers off west of M-95 by 06Z, and
continues to wrap up across the eastern UP through 12Z. However, as
winds shift more northerly behind the exiting shortwave, we may
continue to see some lingering lake effect flurries or light snow
showers especially across portions of Marquette and Alger
counties through Sunday.
After light snow tapers off tonight/Sunday, surface high pressure
building over James Bay will bring about dry weather at least
through early Wednesday. However, light winds and mild lake
temperatures result in a persistent marine layer (shallow
moisture to 2-3kft) and associated low-level cloudiness, except
across the far east where downslope flow limits cloud cover.
Above normal temperatures prevail through the extended forecast
period, except across the east where less cloud cover allows for
more efficient nocturnal cooling and near normal daily average
temperatures.
The overall trend toward a slower system continues with precip onset
possibly holding off well into Wednesday morning. Heights continue to
rise over our region through the beginning of the work week.
Meanwhile, a deepening low pressure system over the Plains will
become vertically stacked by Tuesday night/early Wednesday.
Guidance continues to struggle to bring this much farther east
with the ridge firmly overhead and seeming to suppress this Plains
system further southward as it tries to track towards the Great
Lakes. The low center decays slightly Wednesday and deepens again
over IN by early Thursday. This feature then slowly moves
eastward towards the Atlantic coast through the end of the work
week. Since this low pressure track is not close to our area,
several rounds of light to moderate precip seem most likely. The
first round of precip Wednesday into Wednesday night will be
forced by strong southeasterly warm air advection, but very dry
low levels (pwats ~0.10") delay onset and reduce overall amounts.
Additional rounds of lake enhanced or pure lake effect precip are
possible late next week as low level flow backs northerly.
However, 850mb temps aren`t cold (median values of -4C to -7C) so
precip amounts should remain light.

Weak warn air advection continues to spread snow across the area,
but is beginning to come to an end over the far west. Varying
conditions across the area late this afternoon with KIWD with VFR
ceilings and visibilities, while KCMX is LIFR and KSAW is low end
MVFR. Ceilings will fill back in at KIWD over the next few hours,
and there may be some minor restrictions to visibilities due to BR,
but the snowfall should be done there. KCMX will see ceilings lift a
bit into IFR/low MVFR over the next few hours as the snowfall there
also tapers off before ending around 6Z. Ceilings and visibilities
at KSAW will become IFR later this evening as the snow will persist
there into the early morning hours. not se

.PREV DISCUSSION... /issued 315 PM PST Sat Dec 10 2022/
UPDATED AVIATION DISCUSSION...
SHORT TERM...Tonight through Monday night...A challenging
forecast presents itself as guidance is struggling with the
placement of crucial mesoscale features, and still exhibits some
slight, but important, differences in the synoptic pattern.
The main upper-level, cut-off low is visible just offshore in water
vapor imagery and continues to slowly track southeast. The main
surface low is visible on both visible and Day Cloud Phase satellite
products, located offshore in the northeast Pacific and also
tracking slowly southeast. Ensemble and deterministic guidance are
in excellent agreement that these features will both track southeast
through the night with the surface and parent upper lows both
gradually filling in as they approach the southwest Oregon coast. By
06Z tonight, some subtle placement differences become apparent in
current 12-18Z deterministic guidance as well as 12Z ensemble mean
500 mb heights and vorticity. All guidance agrees on diffluent
southerly flow aloft, but exact location of the mid-level vorticity
maximum remain slightly different among guidance. Moreover,
deterministic runs are hinting at a secondary surface low forming in
south-central or southeast Oregon overnight into Sunday morning.
Model-to-model and run-to-run variances are quite significant with
the NAM favoring a more westward placement in central Oregon while
the HRRR tracks this feature much further east into southeast
Oregon. Of concern, the ECMWF EFI paints a bullseye for
climatologically unusual precipitation and snowfall right over
central Oregon with positive Shift of Tails (SoT) exceeding values
of 1 indicating some extreme outliers among ensemble members.
Indeed, delving further into ensemble members reveals substantial
uncertainty in precipitation totals and snowfall for much of central
and eastern Oregon, dependent upon where the secondary surface low
tracks and where the band of heavy precipitation sets up.
The takeaway is that forecast uncertainty remains notably high for
such a short lead time, and impacts from the moderate to heavy snow
band will be moderate to high, wherever it forms. For now,
confidence in advisory-level snowfall for central Oregon has
prompted a Winter Weather Advisory for 06Z Sunday to 06Z Monday,
though other areas of north-central Oregon through the foothills of
the Blue Mountains and into the eastern mountains may also see
impactful snowfall through Monday as wraparound snow showers linger.
Monday and Monday night, the upper low is anticipated to track
southeast into the Great Basin with the heaviest precipitation
tapering off through Monday afternoon in northeast Oregon. Colder
air will be advected into eastern Oregon and eastern Washington as
flow aloft turns northerly. Plunkett/86
LONG TERM...Tuesday through Saturday... A transition back to
completely dry conditions will be well underway to start the
extended period on Tuesday as the focus shifts to a stable but cold
weather pattern through the end of the week. The ECMWF Extreme
Forecast Index highlights these below normal temperatures for the
inland Pacific Northwest, but doesn`t point to much else in the way
of unusual weather features. Primary impacts will be in the form of
low stratus and freezing fog centered over the Columbia Basin which
may lead to localized slick road conditions.
On Tuesday deterministic and ensemble guidance are in good agreement
in the overall upper-level pattern into the middle of the week as
the axis of a broad long-wave trough continues to progress eastward
through the Rockies and a ridge of high pressure amplifies off the
coast of the Pacific Northwest. Dry northerly flow aloft prevails
overhead leading to completely dry conditions across the CWA. A more
impactful byproduct of this northerly flow is the reinforcement of
cold air over the region advecting southward from British Columbia
leading to well below normal temperatures throughout the inland
Pacific Northwest midweek; -4 to -8 C 850mb temperature anomalies by
Wednesday. Expect high temperatures in the 20s across the Columbia
Basin into Central Oregon, the John-Day Basin, and Grande Ronde
valley Wednesday afternoon. Additionally the fairly tight
temperature spread between the 25th and 75th percentiles in the NBM
ensemble adds confidence to projected below normal temperatures
Tuesday through Thursday and beyond.
Outside of the cold temperatures at the surface, model soundings
from the deterministic GFS and ECMWF indicate the development of a
boundary layer temperature inversion come Tuesday/Wednesday as well,
which combined with near surface moisture would facilitate
persistent low clouds and freezing fog throughout the Columbia Basin
up into the peripheral foothill areas into the end of the week.
Where freezing fog is present slick road conditions follow. This
will be especially true in some of the aforementioned peripheral
foothill areas just above the base of the stratus deck like the
Horse Heaven Hills and portions of US-97/197 where freezing fog
appears most robust.
Guidance begins to diverge further in the progression of the upper-
level pattern towards the end of the week, having ramifications for
potential precipitation chances and temperatures changes going
forward. Come Thursday a “Rex-block” is very likely in place over
the eastern Pacific due to a strong area of high pressure off the
coast of British Columbia and vertically stacked upper-level low off
the coast of California. Although, it is worth noting there is some
ensemble disagreement on the exact placement of the above features.
Locally this should continue to keep conditions dry however a
shortwave dropping southward along the British Columbia/Alberta
boarder into Idaho and Montana Thursday is worth keeping an eye on.
Exploring the Ensemble Cluster Analysis reveals uncertainty in the
placement of this feature although most solutions keep it far enough
to our east to avoid any impacts. Still, nearly 22% of the total
grand ensemble members nudge it westward enough for light snow
shower to potentially move into the northern Blues and Wallowas. In
either case, guidance continues to trend high and low temperatures
even lower into the first half of the weekend; nearly 10-20 degrees
below normal across the region come Friday and Saturday.
Schuldt/99
AVIATION...00Z TAFs...Mostly VFR conditions continue the rest of
the afternoon into the early evening hours although YKM may see
CIGS/VSBY fall back to MVFR quicker than other sites due to
increasing low clouds and mist. As the night progresses conditions
deteriorate to MVFR and IFR at the rest of the airport sites as CIGS
and VSBY lower. At BDN and RDM, a band of snow swinging northward
from California arrives near 14z although there still uncertainty as
to the exact timing of this precipitation. LIFR can’t be ruled out
at two aforementioned airports but confidence in the
timing/placement of heavier snow in central Oregon remains low
Sunday morning. Breezy winds at KPDT, RDM, BDN, and ALW continue to
decrease this evening, becoming lighter overnight. 99
