.SHORT TERM /THROUGH TUESDAY NIGHT/...
Issued at 240 AM MST Mon Dec 29 2025

Cold temperatures and mostly clear skies were observed early
this morning with temperatures in the single digits and teens.
Gusty west to northwest winds have kept temperatures a little
higher near the mountains, but expect these winds to diminish
further outside of the wind prone areas through sunrise. Wind
chill temperatures haven`t been too cold so far with a few areas
across western Nebraska and the more sheltered valleys of
southeast Wyoming showing wind chill readings slightly below
zero. A few areas may see readings around -10 to -15, so not
expecting to issue a Cold Weather Advisory at this time.

Slow warming trend begins today as an upper level ridge builds
into the area from the eastern Pacific and 700mb temperatures
climb above -5c. High will still be near or slightly below
average day for the day with afternoon temperatures in the 30s
to low 40s. Warming trend will continue into Tuesday as 700mb
temperatures climb above -2c and afternoon highs return to the
low 50s across most of the high plains.

Primary forecast concerns will be another round of locally
strong winds for a few of the wind prone areas of southeast
Wyoming...mainly the Arlington area and the I-80 Summit. Models
backed off on high wind potential yesterday, but have now
trended more aggressive, including in-house wind guidance. 700mb
subsidence looks a lot more favorable as well with some mountain
wave activity detected across Carbon and Albany
counties...possibly extending eastward into Laramie County early
Tuesday morning. Considering we are seeing gusts up to 52 MPH
early this morning from subpar gradients and limited subsidence
near Arlington...decided to issue a High Wind Watch for the
Arlington zone and I-80 Summit/southern Laramie Range. Brief
strong wind gusts are possible across the southern Laramie Range
foothills and the Bordeaux area, but conditions aren`t quite as
favorable in those locations leading to lower than average
confidence. With 700mb winds peaking to near 55 knots, decided
to extend the High Wind Watch into early Tuesday afternoon due
to possible boundary layer mixing and another wind max before
winds diminish during the afternoon.

.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
Issued at 325 PM MST Sun Dec 28 2025

Weather, what weather, not so much to talk about in the long term as
ridging slides in and dominates conditions across the CWA for most
of the upcoming work week. So, keep those sunglasses out as that
globe in the sky will be ever so bright under mainly clear skies.
Also, those shorts and flip-flopps might come in handy with highs
soaring into the 40s and 50s, even the low 60s for a few locations
across eastern Wyoming and the Nebraska Panhandle. Nighttime lows,
as a whole, are expected to only dip into the 20s through extended.
All this is due to upper level ridging that slides across the
Intermountain West into our region by Wednesday, weakening a bit
Thursday as energy moves in from the west. This upper level energy
will increase cloudiness and chances of precipitation, with the
greatest threat across our western forecast zones late Thursday
through Friday morning. The bulk of the precipitation will not make
it to or much past the I-25 corridor. Then, ridging makes a
triumphant return once again late Friday into Saturday morning,
ending any threat of precipitation. Finally, heading into next
weekend, the potential for another system to impact our CWA, once
again primarily west of the I-25 corridor, increases. In-house
guidance have differing solutions of timing and placement of the
precipitation, so there is plenty of time between now and then to
fine tune the forecast. Winds, which have been hammering our known
wind prone areas over the previous several weeks, will continue to
be weaker and we get a reprieve from any major events for the
duration of the long term period.

.AVIATION /18Z TAFS THROUGH 18Z TUESDAY/...
Issued at 1030 AM MST Mon Dec 29 2025

VFR conditions expected over the next 24 hours. Skies mostly
clear, perhaps an occasional high cloud in the NE Panhandle.
Winds generally 10-12 knots or less outside of an occasional
gust but overall winds expected around or under 20 knots through
the period.
