.SHORT TERM /THROUGH THURSDAY/...
Issued at 250 AM MST Tue Jan 20 2026

High Wind Warnings look on track early this morning for the wind
prone areas of southeast Wyoming. Arlington area has gusted up
to 62 MPH already with winds increasing further to the east over
the southern Laramie Range the past hour or two. Current high
res guidance shows a somewhat lower chance for strong winds for
the Bordeaux area/I-25 south of Wheatland. In-house wind
guidance suggests this as well with probabilities below 25% to
30%. Will keep the Warning going for now and will also monitor
the southern Laramie Range foothills west of Cheyenne.
Otherwise, current forecast for today looks on track. Surface
cold front will dig south out of Canada through this afternoon.
Should see late morning/early afternoon highs near 50 degrees
for far southeast Wyoming and the central/southern Nebraska
Panhandle. However, once the front moves across the area...expect
afternoon temperatures to quickly drop back into the 30s by
sunset or shortly thereafter. Periods of light snow and/or
flurries expected along and immediately behind the cold front
this afternoon and this evening, mainly over southeast Wyoming.
Any snow accumulations should remain below a half an inch
outside of the mountains, with most places seeing a dusting
between 3 PM and 9 PM.

Seasonably cold temperatures are expected Wednesday and Thursday
as another reinforcing shot of colder air moves into the area
later Wednesday and into Thursday. Most of Wednesday will not be
too bad closer to the I-80 corridor as surface winds shift a
little more out of the west, allowing some downslope component
to the wind direction through the day. Bulk of the colder air
begins to arrive late Wednesday night and Thursday with high
temperatures struggling to reach freezing across much of the
area. No precipitation expected with the secondary shot of
colder air on Thursday, with the bulk of the arctic airmass
remaining just to our northeast. Thankfully, winds should ease
by Thursday ahead of the next cold front later this week.

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
Issued at 252 PM MST Mon Jan 19 2026

The long term has a stronger signal for a more active end to
the month but that may not necessarily equate to significant
snow events. The ridge over the West Coast is preventing a lot
moisture from advecting into the Intermountain West often leading
to moisture starved systems and little snow accumulations. A
more favorable chance of snow likely is going to be Friday into
Saturday. The upper level trough pushing through will be a lot
stronger as that low pressure system over the Hudson Bay wobbles
a little more south. However, the question becomes how much
moisture will we have to be able to utilize as the trough moves
through. The models still retain a little moisture ahead of the
trough moving through just like in previous runs however, the
intermountain west has a habit of drying out faster than models
projected. Another caveat, is the ridge over the West coast
looks to be rebuilding later in the week which may also lead to
drier conditions and less available moisture that originally
modeled. Low Pops were kept for this potential scenario however,
if we do have a slower building ridge than we can reasonably
expect higher snow totals and more widespread snow showers in
the lower elevations. The probabilities for 1 inch of snow for
the high plains is still about 10 to 20 percent.

.AVIATION /12Z TAFS THROUGH 12Z WEDNESDAY/...
Issued at 505 AM MST Tue Jan 20 2026

Surface cold front will push south across the region today and into
Colorado by this evening. Gusty West to northwest winds will shift
out of the north with brief snow flurries or snow showers possible
this afternoon through this evening.

HAZARDS/WEATHER TRENDS: VFR conditions will prevail over the next 24
hours with intervals of midlevel clouds. LLWS will continue over the
next few hours for mainly KCYS and KLAR. Winds will then increase
after 15z with west winds shifting into the northwest with gusts of
25 to 35 knots. Some light snow will accompany the front, but kept
out of the TAF for now due to low confidence and questionable areal
coverage.
