.KEY MESSAGES...

  throughout the week, with the strongest shot of cold air
  expected Friday. Precipitation chances will be minimal with
  each front.

.SHORT TERM /THROUGH THURSDAY/...
Issued at 337 PM MST Tue Jan 20 2026

Current observations show the cold front beginning to drop into the
northern reaches of the CWA. Observations along US-20 show winds
turning out of the north with gradually falling temperatures. The
front should continue to make its way south over the next few
hours, with it completely through the CWA by this evening.
Precipitation looks possible behind the frontal passage.
Observations in northern Wyoming do show light radar returns
with ASOS stations confirming precipitation. Given the origin of
the front, moisture will be minimal, however, lift provided by
the front will likely be enough to produce light snow showers.
Hi-Res guidance keeps most of the shower activity in Wyoming,
but those in Nebraska should not be surprised to see a few
flakes fly this evening. Accumulating snow is not expected.
Luckily, the effects of this fast moving cold front will only be
felt tonight with low temperatures in the teens and single
digits.

Cold air aloft will quickly be ushered out Wednesday morning with
winds turning more westerly. 700 mb temperatures will be in the
negative single digits which will lead to highs roughly near-average
for most of the CWA. With the more westerly winds and jet energy
aloft, Wednesday will be another breezy day, however the threat of
high winds will be low. Drier air aloft will also move in leading to
mostly sunny skies throughout much of the day. Another cold front
will move into the area Wednesday evening, bringing more cloud cover
and colder temperatures. High temperatures on Thursday will be much
cooler, with highs anywhere from 5 to 15 degrees cooler than
Wednesday. Cloud cover will help keep temperatures below
average, but luckily winds will be on the light side so apparent
temperature should be close to the actual temperature. Once
again, precipitation chances will be minimal.

.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
Issued at 337 PM MST Tue Jan 20 2026

Chilly days expected to start the long term behind a stout
arctic airmass. Overnight temperatures into Friday morning will
range between the single digits to negatives, with highs only
peaking into the teens, and some low 20`s for our western
zones. Meanwhile the passing system should bring a shot of snow
that currently doesn`t look insignificant - probabilities for
0.1 inch or more over 24 hours are at 40-60%, and 1 inch or
greater 15-30%. While these probabilities aren`t a certainty or
spectacularly high, they`re higher than most of what we`ve seen
this season, giving hope for at least a little bit of
precipitation during our drier than normal winter. Saturday
morning will bring another cold morning as lows descend into the
low single digits and negatives, thankfully winds will not be
breezy saving us from cold weather products for the day. Sub-
freezing highs persist through Sunday, with ridging bringing a
warming trend back by Monday and bringing us to near to above
normal for highs. Some breezy winds are also expected with
pressure gradients tightening, primarily on Sunday into Monday,
but upper level winds aren`t expected to be supportive of
stronger gusts and in house guidance struggles to produce
probabilities greater than 25% for high wind warnings (58+ mph).
Overall while active, chilly, and getting a small chance at
some snow, the long term shouldn`t be too busy for this time of
year.

.AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/...
Issued at 420 PM MST Tue Jan 20 2026

High clouds are rolling through; however, they pose no threat to
aviation operations, so VFR conditions will prevail across all
terminals for the duration of this TAF period. Breezy winds
impacting all terminals should decrease rather rapidly through the
evening to less than 15 knots by 07Z Wednesday. This calmness is
short lived as they will ramp up once again Wednesday morning.
