.SHORT TERM...(Today through Monday night)
Issued at 305 AM MST Sun Dec 4 2022
Current surface observations across the area show temperatures not
quite as cold as yesterday morning with readings in the teens to
mid 20s across the eastern plains of western Nebraska and
southeast Wyoming. Further west, cloud cover from mountain wave
clouds, and the retreating arctic cold front, has kept
temperatures relatively mild and generally in the 30s. Expect lows
to eventually drop into the 20s to near 30 in these locations
once the cloud cover dissipates a little towards dawn. Otherwise,
quiet day today with increasing winds for the Wind Prone areas by
this afternoon.
Primary forecast concern today and tonight will be locally strong
winds for the Wind Prone areas. Not the best set up this season
with marginal low level pressure gradients present ahead of the
next Pacific disturbance and associated jet energy. However,
models still show impressive low level subsidence and evidence of
strong mountain wave activity. 700mb winds continue to be around
55 to 60 knots for a time tonight. In-house models and NBM 4.1
have been consistent with showing winds around or slightly above
60 MPH. Therefore, upgraded the High Wind Watch to a Warning for
the most favorable locations including the Arlington/Elk Mountain
area and the I-80 Summit. The overall pattern favors these
locations a bit more than the other due to persistent westerly
flow and the best low level pressure gradients. Not nearly as
confident with the Bordeaux area with in-house models trending
lower with probabilities, but still kept the High Wind Watch out
for now. Added the southern Laramie Range foothills to the Watch
since peak subsidence and a breaking mountain wave are possible in
this area towards early Monday morning. Winds and downslope flow
should keep low temperatures in the upper 20s to mid 30s for most
of the night along and west of the I-25 corridor. The arctic front
across the Dakotas is expected to return to east central Wyoming
and the northern Nebraska Panhandle tonight with temps dropping
into the teens overnight. This front will eventually lower the
winds across the Wind Prone early Monday as it moves south across
the eastern plains.
For Monday and Monday night, possibly a tricky forecast setting up
for mainly the eastern plains, but also in the mountains. Upper
level disturbance and strong 125 kt jet will interact with the
arctic front moving southward across the eastern plains of far
eastern Wyoming and western Nebraska. These arctic boundaries tend
to be tricky in this area and tough to predict movement and
location. Although models are showing this front only clipping the
I-25 corridor, would not be surprised if this airmass moves into
the Laramie Range and stalls for a time Monday night. Models have
trended higher on QPF and snowfall as this disturbance interacts
with the front, so increased POP and added light accumulations of
snow to the I-80 corridor from Arlington eastward towards the
southern Nebraska Panhandle where model Omega shows the best lift
and some WAA aloft. Not expecting much accumulation from this
system, but with the arctic airmass nearby and the potential for
icy roads due to daytime temperatures in the low 40s on Monday,
wanted to add something to alert of possible travel impacts.
Otherwise, the Sierra Madre Range should do pretty well with this
persistent light to moderate upslope snowfall, so issued a Winter
Weather Advisory for 5 to 10 inches of snow and locally higher
amounts. Included the Snowy Range, but mainly the northern
portion of the zone which tends to do well in westerly flow. Will
have to monitor the foothills (Arlington/Elk Mountain) and the
I-80 Summit since 1 to 2 inches of snow are possible, but not
expecting anything more than minor impacts at this time.
.LONG TERM...(Tuesday - Saturday)
Issued at 200 AM MST Sun Dec 4 2022
Looking ahead into the middle of next week, should see fairly
steady temperatures near to slightly below normal for early
December along with a windy pattern, through maybe not necessarily
high winds. Zonal flow aloft will continue Tuesday as the
moisture stream steadily shifts south into CO as an upper level
low off the CA coast digs southeast. This should reduce the chance
of mountain snowfall for the Sierra Madres, though cannot rule
out additional light accumulations. 700mb flow will reach around
40 kt for the area leading to breezy conditions across southeast
WY. While not expecting high winds, gusts 40-50 mph will still be
possible for the wind-prone locations. The upper level low off the
CA coast earlier in the week will quickly eject across the
central plains headed into Thursday as another system approaches
the Pacific coast late in the week. Should see MSLP gradients
tighten up across the Laramie Range with increasing 700mb flow
resulting in another chance for elevated winds for the wind-prone
locations and areas east of the South Laramie Range. Precipitation
chances look minimal at this time for Saturday, with portions of
Carbon and Albany Co having the best chance to see some snowfall.
However, west/northwest flow will dry out precipitation for areas
farther east. Did trend temperatures slightly downward for the
weekend as 700mb temps drop towards -15C behind this system per
the latest GFS/GEFS.

.AVIATION...(For the 18Z TAFS through 18Z Monday afternoon)
Issued at 1038 AM MST Sun Dec 4 2022
Mostly VFR expected for the forecast period, though KRWL and KLAR
have a possibility for CIG/VIS reductions with light snow showers
developing in the vicinity Monday morning. Elsewhere, increasing
mid-level cloud cover is likely overnight, but should remain VFR.
Otherwise, mostly a wind forecast with stronger winds in Wyoming.
Expect gusts around 25 to 30 knots this afternoon in WY, which
will decouple from the surface after sundown. However, strong
winds are expected to develop just above the surface overnight, so
significant LLWS is likely at KLAR and KCYS. Strong westerly
winds could occasionally breach the shallow surface inversion at
KCYS and KLAR, bringing overnight gusts in, but the timing of this
is uncertain since this will likely be related to mountain wave
activity. Nebraska panhandle terminals can expect winds to shift
to the N or NE early Monday as a weak front slides through.
