.DISCUSSION...
Issued at 339 PM CDT Thu Oct 17 2024
The strong surface high to the east of the forecast area continues
to move eastward towards Appalachia, and a trough continues to
deeper over the northern Rockies as forecasted. These two systems
have helped to build a tight and significant pressure gradient over
the western Great Plains. As expected, the ensemble means had
underdone the sustained and gusting wind speeds. Current
observations across SW Kansas winds are between 25-35 mph with gusts
up to 45 mph. The wind forecast for the rest of Thursday and into
Friday are similar to these values as the synoptic setup is expected
to remain very favorable for strong geostrophic winds. The NBM 90th
has been the baseline for the wind forecast with intermittent tweaks
in the most conducive/sensitive areas. The very high wind speeds are
the only highlight in the near term; blowing dust and fire weather
risk are by-products of the wind and worth monitoring. The very dry
ground surface paired with the high winds could create areas of
blowing dust, temporarily reducing visibilities. Transportation
services should be cognizant of the potential and take the
appropriate precautions. The winds have also resulted in the SPC
placing the northern most forecast zones in a critical fire weather
day. With higher RH values than yesterday and continued water vapor
transport, SW Kansas will not reach Red Flag Warning criteria.
Despite this, caution is still advised as fires that are able to
start may be unpredictable and very hard to control. Highs across SW
Kansas will fight to reach the 80s Thursday and ensembles are giving
the farthest NW edges of the CWA the best chances as the majority of
SW Kansas will peak in the high 70s. The strong south winds will try
to prevent overnight temperatures from dropping into the 40s with
Friday highs bouncing back into the 70s with ensembles means
blanketing low 70s across all of SW Kansas.
Models and ensembles alike have held firm over the last few days
that the low pressure system of the northern Rockies will continue
to deepen and develop into a closed low centered near the Four
Corners states before stalling out on Friday. There has also been
wide agreement that a largely north/south oriented band of heavy
precipitation will form in front of the low along eastern Colorado.
Unfortunately for the forecast area, model disagreement is largest
regarding when and how much rain SW Kansas will see. Some models
like the NAMNST and HRRR have precipitation developing ahead of the
main line while other models such as the ECMWF stubbornly keep
almost all precipitation inside Colorado until the later half of the
weekend. When the main line of heaviest precipitation arrives is
predicated on when the closed low gets ejected. Ensemble means has
this occurring during the Saturday/Sunday overnight. Deterministic
models have around a 24 hour range of solutions on when exactly it
occurs. Before sunset on Saturday, ensembles >50% for 0.25" remains
west of highway 83. The likely outcome is that east of highway 83,
the CWA sees less than 0.25" in the form of discreet and scattered
storms before Sunday. Once the low and main band of precipitation
moves east, the forecast area will see its` best chance for
accumulations. If the low or main band stalls to the east of model
consensus, areas along the Colorado/Kansas border could receive up
to 3" in total. While this is a fairly low probability (~25% per the
NBM) it is worth mentioned due to the potential flash flooding
impacts. WPC has the farthest edge of west Kansas in a slight risk
for their excessive rainfall outlook. Highlighting the higher end
outcomes is not representative of the confidence in that solution,
but rather the potential for higher end impacts. Ensemble means
range from 2.5"-0.75" for the entire forecast area, but inevitably
some places will receive less especially in the eastern zones if the
low takes a slower or more stubborn reality.
After Monday, by the time the low and precipitation has left the
forecast area, another prolonged period of dry and warm weather is
expected. Behind the trough, models/ensembles have a zonal flow
regime taking over across the majority of the CONUS. The entirety of
next week after Monday has ensembles keeping accumulation chances at
or below 5%. Highs in the forecast are primarily in the 70s with
Tuesday having a 50% chance to reach the 80s via ensembles.

.AVIATION /00Z TAFS THROUGH 00Z SATURDAY/...
Issued at 556 PM CDT Thu Oct 17 2024
A surface tough of low pressure over the eastern Colorado
Plains in combination with a huge eastern CONUS high pressure
has set the stage for windy conditions across western Kansas for
a bit of a prolonged period. Southerly winds can be expected no
less than around 18-10 knots and gusting from 25-32 knots
overnight on a area wide basis. Look for VFR conditions as the
moisture content of the atmosphere remains low, precluding any
ceilings or fog development. By the daytime hours on Friday ,
cloud ceiling probablistic models indicate around a 50 percent
chance for sun 3000ft ceilings approaching Liberal from the
southwest after about 21z.
&&
.FIRE WEATHER...
Issued at 339 PM CDT Thu Oct 17 2024
Strong winds have been the focus of Thursday/Friday. Current RH
values are between 20-30% for the entire forecast area and is not
expected to drop much lower. Therefore, there is no Red Flag Warning
despite the winds reaching up to 35 mph and even higher gusts. The
SPC has the far northern zones in a critical fire weather day, and
fire weather precautions should be advised as the strong winds can
make fire unpredictable and hard to control even without the
warning.

.MESOSCALE UPDATE...
Issued at 913 PM CDT Thu Oct 17 2024
Clear skies and mostly calm winds tonight should allow for temps
to cool pretty close to where they registered early this morning.
Have lowered min temps to near this morning`s lows. The rest of
the forecast remains on track. Expect another dry day tomorrow
with low RH mixing out through the afternoon. /NF/
&&
.DISCUSSION...
Issued at 136 PM CDT Thu Oct 17 2024
Today and tomorrow...
An upper ridging pattern over east/southeastern CONUS will leave the
Lower Miss quiet and dry during the near term period. E/NE flow will
leave very little opportunities for incoming moisture as the bone
dry airmass hovers over the region. RAP analysis has PWATS sitting
below 0.5 inches, which will continue to enable critically low minRH
values. RH looks to remain between 20-30% the remainder of today and
tomorrow. Dur to this, a "Limited" for dangerous fire conditions
will continue through the end of the week. Luckily, winds have
calmed after the frontal passage and look to remain calm through
tomorrow. Highs today will top out in the upper 60s to low 70s.
Overnight, clear skies and light winds will promoted efficient
evaporational cooling. Lows are expected to be cooler than last
night, with temperatures in the upper 30s near the Golden Triangle
Region and lower 40s elsewhere. By sunrise, diurnal warming will be
fairly efficient, with clear skies once again. Highs are expected to
top out in the low to middle 70s. Similar to today, fire danger will
continue to be a concern. Otherwise, quiet conditions are expected
across the ArkLaMiss region. /AJ/
This weekend through next work week: We will remain in a very dry
pattern through the remainder of the forecast period. Broad surface
ridging will persist over the eastern CONUS into early next week.
With cold advection no longer occurring, temps will begin to trend
back upward within this regime, with highs returning to above normal
Sunday into Monday. Lows will still remain below normal to near
normal over the next few days. A midweek upper shortwave will bring
another reinforcing dry cold front southward toward our region
around next Thursday, but it is unclear how far south this front
will make it before stalling out. Nevertheless, given the continued
lack of atmospheric moisture, the forecast remains rain free.
With respect to ongoing fire weather concerns, conditions will
remain quite dry this weekend, with RHs potentially dropping into
the 20 to 30 percent range again on Saturday and Sunday. Generally
light winds should help mitigate major fire weather concerns, but we
may ultimately need to extend the current limited fire danger
outlook into this time period. /DL/

845 PM EDT Thu Oct 17 2024
.SYNOPSIS...
Canadian high pressure will build across the mid Atlantic through
the end of the week, then remain in place while gradually warming
through early next week.
&&
.NEAR TERM /THROUGH TONIGHT/...
As of 845 PM Thursday...
* A Frost Advisory remains in effect for much of the Piedmont, the
western Sandhills, and the northern Coastal Plain of North Carolina
from midnight to 9 AM EDT Fri.
Forecast is in good shape. The vast majority of surface obs across
the area have already gone calm beneath the heart of the surface
ridge. With clear skies tonight amidst a dry column both in situ (as
seen on the 00z GSO sounding) and upstream (noted on satellite
imagery), radiational cooling conditions will remain excellent.
Despite this, temps so far have been falling at a slightly slower
pace than expected. But the latest guidance (including the bias-
corrected RAP and HREF probabilities of temps less than 36F)
continues to support temps bottoming out a bit beyond current
dewpoints, in the mid 30s to near 40, with isolated lower 30s
possible in the typically cooler and outlying areas, so will hold
the frost advisory as is. Note that low temps across any particular
county could vary by several degrees. -GIH
Previous discussion from 250 PM: Forecast rationale remains
unchanged through tonight. In slowly progressive mid/upr-level flow,
a cyclone just east of the NC Outer Banks will fill while drifting
newd and away from the middle Atlantic coast, while an anticyclone
over the mid MS Valley will strengthen while migrating across the OH
Valley and Great Lakes. A prominent subsidence inversion based
around 6000 ft AGL in the 12Z-observed GSO sounding will further
warm and lower amid strong, 100-150 meter mid-level height rises and
subsidence that will follow the departing cyclone across and
offshore the srn middle Atlantic and Carolinas through tonight. 1030
mb, cP surface high pressure centered over the lwr OH Valley will
likewise migrate ewd, strengthen, and become centered over the cntl
Appalachians at 1034-1035 mb by 12Z Fri. Associated, occasionally
breezy nly flow over cntl NC this afternoon will diminish and become
calm and frosty tonight over the Piedmont, and lightly stirred and a
little less chilly (mostly upr 30s to around 40 F) in the Coastal
Plain.
&&
.SHORT TERM /FRIDAY AND FRIDAY NIGHT/...
As of 220 PM Thursday...
Surface high pressure will be centered over the mid-Atlantic states
and will move little over this 24 hour period. After some frost
around sunrise, another sunny day is expected. Upper level heights
will be rising slightly, and this should allow for highs to rise
about 5 degrees warmer than today`s values, although these numbers
will still be below normal. Low temperatures will rise about 3-5
degrees higher than tonight`s values. Cannot rule out the potential
for some frost, however temperatures are expected to be warm enough
that this will not be a widespread concern.
&&
.LONG TERM /SATURDAY THROUGH THURSDAY/...
As of 135 PM Thursday...
Aloft, the longwave ridge should remain over the eastern US Sat/Sat
night, shifting slightly westward but still ridging ewd into the mid-
Atlantic Sun and Mon. Meanwhile, a deep cutoff low will sit over the
Four Corners over the weekend, blocked by the ridge to the east.
This low will then lift newd through the Rockies and into the n-ctl
Plains Sun night/Mon. The medium-range guidance continues to vary
with the subsequent speed, strength, and track of this low as it
continues generally ewd. Regardless, this low will gradually
suppress the ridge swd as it moves through the Midwest and into the
OH Valley or Great Lakes early next week. The best chance for the
low/trough to clip or move through the mid-Atlantic/NC will be
sometime Tue night/Wed. The forecast for central NC will depend on
what happens with this low, resulting in continued forecast
uncertainty for Tue through Thu next week. A northern stream s/w
could swing through the area behind the initial low/trough on Thu.
At the surface, cool high pressure over the Northeast US on Sat will
gradually weaken as it slides sswwd along the Appalachians through
Sat night, while continuing to extend into central NC. The high
should settle over the TN Valley Sun/Sun night before progressing
ewd through the mid-Atlantic mid-week Mon/Tue. While it is unclear
how long the high will continue to ridge wwd into the area after it
moves offshore, model guidance does suggest a pre-frontal trough
will move through the area on Wed/Wed night, ahead of a cold front
passage possible sometime Thu/Thu night.
For now, the weather is expected to remain dry through the extended
forecast period. However, cannot rule out some precipitation with
the s/w Wed night/Thu, mainly across the north. Temperatures will
gently moderate through mid-week, then fall again behind the front.
&&

As of 645 PM Thursday...
VFR conditions will continue through the TAF period.
Outlook: A prolonged period of high pressure will favor fair weather
and VFR conditions through Wednesday.

the I-49 corridor, with a Red Flag Warning in effect for
portions of western Missouri and far southeast Kansas until
7PM tonight.
- Elsewhere, elevated to locally significant fire weather
conditions today, which continue into Friday.

.SHORT TERM /THROUGH TONIGHT/...
Issued at 258 PM CDT Thu Oct 17 2024
Current conditions and synoptic overview:
A surface high sits to our east over the central Ohio River Valley,
and a westward tilt with height is evident as the center of the
ridge aloft sits nearly overhead. A tight southwest-to-northeast-
oriented pressure gradient extends from our beloved Missouri Ozarks
through the Plains to a developing system in central Colorado.
Amidst southerly winds, weak temperature advection is bringing a
small increase in low-level temperatures that is translating to
warmer surface temperatures than the past couple days. Moisture
advection is also minimal-to-nonexistent; despite the upstream air
originating from the Gulf, there is no moisture transport associated
with this southerly flow pattern. Skies are clear and the air is dry.
The surface high pressure and associated ridge will continue to
slide northeast through the day tomorrow, while the system in the
Rockies pushes southeast through the High Plains. A persistent low
just off the mid-Atlantic coast will push the high into New England
and the pressure gradient over our area will weaken through the
overnight hours tonight and through the day tomorrow.
High temperatures this afternoon will range from the mid-60s in the
eastern Ozarks and the low 70s in the high terrain and areas north
of I-44. Lows tonight will dip into the mid-30s in the eastern
Ozarks and the low 40s through the rest of southwest MO/southeast
KS. Tomorrow will look similar but a few degrees warmer- upper 60s
in the eastern Ozarks, mid-70s through the rest of the region.
One item of note: after two nights of temperatures well-below
freezing in the eastern Ozarks, we are considering the growing
season over after a hard freeze. No more freeze products will be
issued for the season.
&&
.LONG TERM /FRIDAY THROUGH THURSDAY/...
Issued at 258 PM CDT Thu Oct 17 2024
This weekend will see weaker winds and a little higher RH
values, decreasing fire weather concerns. Highs will be in the
70s.
An upper level system is shown moving north of the area early
next week, which may lead to some rain on Monday. The airmass
is fairly dry though, which limits chances for rain to 15-40%
(highest northwest) and amounts should be light. NBM
probability of >=0.5" of rain is less than 20%.
Highs Monday through Wednesday will be in the mid 70s to around
80.
&&
.AVIATION /00Z TAFS THROUGH 00Z SATURDAY/...
Issued at 555 PM CDT Thu Oct 17 2024
High confidence in VFR conditions prevailing through the TAF
period. South-southeast winds at 5 to 10 knots with mostly clear
skies.
&&
.FIRE WEATHER...
Issued at 258 PM CDT Thu Oct 17 2024
Fire weather is the name of the game in the short term, with
significant fire weather concerns both today and tomorrow, though
concerns are a little higher today than tomorrow. Generously-
positioned satellite mesosectors have been helping us detect fires,
and hotspots have been popping for several hours at the time of
writing. Fire detection that early in the day usually bodes for an
active afternoon.
A Red Flag Warning is in effect for our southeast Kansas counties
and three of our western Missouri counties until 7 PM tonight. A Red
Flag Warning seems unlikely to be issued again tomorrow due to wind
speeds remaining below threshold. It is worth noting that fuel
moistures are below 10% in many areas, which provide ample burning
material. This morning`s update of the Drought Monitor indicates an
expansion to the northeast of D3 (Extreme) drought, and with no rain
in the forecast, fuels will likely remain ripe for burning.
Moisture:
The low-levels have been incredibly efficient in mixing
unusually dry air (mid-level dew point depressions around 45
degrees) down to the surface, and most models have been
significantly overestimating surface dew points. The 12Z sounding
recorded the record lowest precipitable water value on record for
the date of October 17. The HRRR seems to be doing the best, picking
up on a pocket of dry air in the higher terrain around the Branson
area. We`ve gone with a special in-house superblend for dew points,
which are reflecting the widespread relative humidity values of 30%
or less, which will decrease further through the afternoon
(potentially as low as 10% in some areas).
Winds:
With the strong pressure gradient across the Plains, winds
are gusty, especially in the west. There`s been recorded gusts
between 20-25mph through the late morning and early afternoon hours
at Pittsburg, Fort Scott, and Joplin. However, the strongest winds
are certain to remain west of our area since we`re located right on
the edge of the high and the fringes of where the pressure gradient
tightens. Sustained winds of 15-20 mph will continue into this
evening, and may reappear in our Kansas counties tomorrow. Winds
have also been a little gusty in south-central Missouri, with
consistent 15-20mph gusts in Osage Beach and Rolla. Winds will
weaken tomorrow as the high moves to the east and the pressure
gradient weakens some.

Area Forecast Discussion
National Weather Service Salt Lake City UT
348 PM MDT Thu Oct 17 2024
.SYNOPSIS...A winter-like storm will impact the region through
Saturday morning. A strong cold front will cross the region
Thursday evening into Friday morning. Significant mountain snow
is expected, along with widespread valley rain. High pressure
will build back into the region Sunday into early next week.
&&
.SHORT TERM (Through 00Z Sunday)...A significant winter-like storm
system will impact the forecast area through the short term
period. Presently, the cold front which pushed through northern
Utah/southwest Wyoming overnight stretches across central Utah,
with the trailing 700mb baroclinic zone stretching from the Uintas
back to near Ely NV. Scattered convection along and ahead of this
baroclinic zone has produced small hail along with occasional
lightning, and this will likely persist into the evening hours.
Looking upstream, a vigorous shortwave trough is digging into the
western Great Basin, with the associated cold front accompanied by
widespread precipitation noted across northern NV. As this wave
digs through NV tonight, the associated frontal zone will surge
across the forecast area, bringing widespread valley rain and
mountain snow. The best forcing and low level cold air will track
through west central and southwest Utah this evening into the
overnight hours, where the heaviest precipitation is expected to
bank up against the terrain along/east of I-15. 700mb temps across
southwest/west central Utah will fall to -8C overnight, and
combined with high precip rates anticipate snow levels to fall to
the valley floors from Fillmore to Cedar City. Although surface
temperatures remain quite warm for mid October, snowfall rates
will likely allow for slushy accumulation at times along roadways,
as well as considerable accumulation on grassy/elevated surfaces
and could result in tree damage to trees which still have leaves.
As such have expanded the Winter Weather Advisory into these
locations for tonight through Friday morning.
With much colder air spreading over northern Utah and the GSL (and
other lakes) running roughly 10F above normal, expect lake
enhanced snowfall primarily impacting locations south of the GSL
and potentially Utah Lake as well. This would mainly impact
far western Salt Lake Valley into the Oquirrh range. Heavier
precipitation could drag snow levels down to the west benches
with some accumulation possible on grassy/elevates surfaces.
Otherwise, 12Z guidance was in good agreement with previous
forecasts, so not much change to the overall forecast snowfall
totals, and going winter headlines seem to cover the situation
well.
With the upper low eventually closing off and tracking across
northern AZ late Friday into Saturday, A period of easterly to
east-northeasterly flow will likely become established across
northern Utah. Previous guidance was in strong agreement with this
scenario, however some 12Z guidance including the GFS has trended
much weaker with the low level cold advection and keeps a more
northerly component to the wind field. That said, as we move into
the hi-res window all 12Z HREF members indicate at least advisory
level downslope winds develop along the northern Wasatch Front,
with some members including the HRRR producing warning level
winds. As such have gone with a High Wind Watch for this area,
with the peak winds expected Friday evening.
Lastly, with the much colder airmass moving into the region many
locations which have yet to experience a freeze this year will see
their first sub-freezing temperatures. Going Freeze warnings for
west central/southwest Utah along with the Sevier/Sanpete Valleys
remains in effect, and these locations should see their first
freeze tonight and particularly Friday night. Temperature guidance
has trended a bit warmer, particularly across Castle Country,
where it`s looking less likely min temps reach the freezing mark
Friday night. Have maintained the Freeze Watch for these areas,
although it appears cloud cover may keep some of these locations
from reaching the freezing mark.
.LONG TERM (After 00Z Sunday)...The upper low remains over
Arizona at the beginning of the long-term forecast period. It will
then slowly eject across the Four Corners region through the day
Sunday before exiting across Colorado Sunday night. Cluster
analysis of model ensembles show good agreement with this timing
and track, with only very subtle differences between the clusters.
As such, expect some lingering precipitation wrapping around the
low (in the form of valley rain and mountain snow), affecting
mainly eastern Utah, through the day Sunday. Temperatures will
warm slightly from Saturday as cloud cover gradually decreases.
Heading into the early through middle part of the week, a low-
amplitude ridge will build into the area. However, there are some
indications that a shortwave trough will pass by to the north,
bringing more zonal flow to the area. Any impacts to the weather
should remain relatively minor, most likely bringing some additional
cloud cover to the area while briefly slowing down an otherwise
warming and drying trend. Speaking of the warming trend, afternoon
max temperatures are forecast to reach around 5-10 degrees above
normal by Tuesday or Wednesday. However, overnight mins, while
generally above normally, will remain cold enough for frost or a
light freeze in some of the normally colder valleys.
Thereafter, models indicate a storm will be brewing off the West
Coast near 130-135W by Thursday morning. Depending on how far east
this storm will be positioned, southwest flow could potentially
increase over Utah by Thursday afternoon. Most models do want to
weaken this storm before moving it inland next weekend.
&&
.AVIATION...KSLC...VFR conditions are expected to prevail during
the remainder of the afternoon at the SLC terminal with ceilings
near 7000 feet AGL. Rain will become more widespread as the front
approaches between 03Z and 05Z, bringing a return of prevailing
MVFR conditions through the overnight hours. West to northwest
winds will prevail, becoming stronger with the front. However, in
the vicinity of showers the terminal will see some erratic wind
directions, with speeds generally expected to remain at or below
seven knots. There is a 30 percent chance of IFR conditions
developing for a time in rain or a mix of rain and snow in heavier
rates with the passage of the front.
.REST OF UTAH AND SOUTHWEST WYOMING...Currently seeing prevailing
VFR conditions across the airspace with some pockets of MVFR/IFR
conditions in scattered rain and snow showers. Rain and snow will
increase over northern and western Utah early this evening as a
stronger cold front moves through, resulting in more widespread
rain and snow with lowering snow levels, and thus more widespread
MVFR and IFR conditions. Overnight, as the front continues
southeast, the precipitation will spread into much of central and
southern Utah, further increasing coverage of MVFR and IFR
conditions. West to northwest winds will prevail over northern
Utah and southwest Wyoming, increasing for a time with the front.
Over southern Utah, occasionally gusty southerly winds will shift
to the northwest with the frontal passage.
&&
.FIRE WEATHER...A cold Pacific storm system moving into the Great
Basin will bring much colder temperatures along with widespread
valley rain and mountain snow across much of Utah through the
remainder of the week. The main cold front currently crossing
northern Nevada will push through Utah tonight, ushering much
colder air into the region and dropping snow levels to near 5000
feet. Widespread valley rain and mountain snow will develop along
and behind this front, persisting overnight and through much of
the day Friday. Precipitation will linger across portions of
southern Utah into the day Saturday before the low pressure system
exits the area. A drying and warming trend will follow for the
early to middle portion of next week as temperatures return to
near normal.
