.SHORT TERM /THROUGH TUESDAY NIGHT/...
Issued at 116 AM MST Mon Jan 26 2026

Very cold temperatures are ongoing tonight behind an arctic front
that passed through Sunday. Temperatures in the Panhandle are
currently in the -15 to -5F range, with Scottsbluff as the coldest
point as of 08Z tonight, sitting at -16F. Across southeast Wyoming,
temperatures are anywhere from -15F to 8F in the warmer locations.
Unfortunately, winds are non-zero, leading to current wind chill
temperatures anywhere from -40 to -20F across much of the region.
Cold Weather Advisories and Extreme Cold Warnings will remain in
effect through the morning hours, ending between 5AM and 8AM. Until
then, bitter cold temperatures will continue with clear skies
further exacerbating the cold.

For today, upper-level flow will remain mostly northwesterly with a
slow transition towards westerly overnight tonight into the early
morning hours Tuesday ahead of a shortwave approaching the region
from the northwest. Further down at 700mb a low will move southeast
across central and southern Canada into the northern CONUS near
Minnesota and Wisconsin. A strong jet is expected to develop with
this low, with strong 700mb winds from the CWA northeastward into
North Dakota and Minnesota. This low will traverse just close enough
to the CWA to increase 700mb height gradients and produce a
secondary jet streak across the Laramie Range and points west and
east. As these winds kick up, the GFS omega fields suggests stronger
downward motion developing, leading to very strong winds in the
typical wind prone locations of southeast Wyoming, as well as the
Laramie Valley and central Laramie County. Craig to Casper height
gradients are expected to be in the upper-80s to low-90s, leading to
increased confidence for very strong winds near the Arlington/Elk
Mountain wind prone zone, where a gust over 80mph cannot be
completely ruled out. Additionally, surface pressure gradients
skyrocket later this morning into the afternoon hour. A gradient of
4 to 6mb is expected across the Arlington wind prone zone, with
surface pressure gradients around 4 to 5mb across the Laramie Range
near the Bordeaux wind prone zone and 2 to 3mb near the I-80 Summit.
The High Wind Warnings for the typical wind prones will remain in
effect through early Tuesday morning. Additionally, expanded the
High Wind Warning to include the Laramie Valley and central Laramie
County. Confidence is lower in these zones as the 700mb flow is a
bit weaker than is expected across the wind prone, but ample
downward omega values should promote downward acceleration of the
winds. Gusts between 60 and 65 mph will be possible in these two
zones through the late morning and evening hours. These zones should
see decreasing winds by 00Z this evening. Expect temperatures this
afternoon to increase back into the 30s and low-40s as downslope
warming takes over the region with the strong winds.

The shortwave pushing into the CWA early Tuesday morning throughout
the day should be fairly dry, leading to no precipitation with this
system. Behind this system a strong upper-level ridge is developing
and will move into the Intermountain West. As a result, warming
temperatures and dry conditions are expected to return to the
region. Elevated winds look likely during the day Tuesday as 700mb
height gradients remain elevated. High winds do not look likely for
Tuesday afternoon at this time. Temperatures will increase back into
the 30s and 40s for much of the area.

.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
Issued at 116 AM MST Mon Jan 26 2026

No major changes, see previous discussion below.

At the start of the long term period, the synoptic pattern is
dominated by a ridge up the West Coast and a deep trough across the
Upper Midwest and Great Lakes region. As we progress through the
forecast period, the ridge slides into our CWA while the trough
pushes ever so slightly to the east. So, expect a relatively benign
week. An embedded shortwave dives south into our area Wednesday,
which may bring an uptick in surface winds, especially in our wind
prones across southeast Wyoming. However, most locations will remain
below the high wind threshold with Arlington having the best chance
with probabilities between 60-80%. Thereafter, ridging quickly
builds back in and controls weather conditions across the region to
round out the extended. With dry conditions, what about
temperatures, will any additional cold surges make into our CWA?
Well, the wintertime temperatures that we had this weekend will be a
distant memory by Tuesday with temperatures soaring back to near or
just above normal. Progressing through the work week, 700mb temps
warm into next weekend as highs will soar into the mid 40s to mid
50s across the CWA. But first, at the start of this forecast period
highs are expected to top out in the mid 30s west of I-25 and low to
mid 40s east of the corridor, highs increasing ever so slightly
through the work week. Low temps will reflect a similar pattern,
increasing nightly, with Tuesday night lows dipping into the teens
and by next weekend, only bottoming out in the low to mid 20s.

.AVIATION /12Z TAFS THROUGH 12Z TUESDAY/...
Issued at 402 AM MST Mon Jan 26 2026

VFR conditions expected through the 12Z TAF period. Clear skies
overnight wil continue throughout the day. Gusty winds are starting
to develop at KRWL, KLAR, and KCYS, and will continue through the
day. Low-level wind shear is possible early this morning, especially
across the Panhandle where surface winds are lighter. Low-level wind
shear dissipates by 16 to 18Z.
