.SHORT TERM /THROUGH MONDAY NIGHT/...
Issued at 325 PM MST Sun Dec 28 2025

Gusty winds continue across most of the forecast area this afternoon
as the CWA sits in strong northwest flow on the backside of the
upper-level trough that brought the arctic air. High Wind Warnings
continue for Arlington and the South Laramie Range and foothills
with gusts of 60 to 65 MPH. Blowing snow has been observed along
Interstate 80, mainly along a 20 miles stretch of highway near
Arlington. Visibilities have dipped below a half mile at times.
Isolated blowing snow has also been seen at Pumpkin Vine near the
Colorado border on US-287, reducing visibility. Winds will ease this
evening as the trough pushes further east into the Great Lakes
Region. Clear skies and calmer winds overnight will cause
temperatures to tank from radiational cooling. Since the NBM doesn`t
usually have temperatures cold enough after an arctic front on
clear, calm nights, decided to drop low temperatures well below NBM
guidance. Went ahead and lowered temperatures in the high valleys
out west below zero due existing snowpack. Wind chills
overnight will be below zero, with the coldest wind chills
expected in the northern Nebraska panhandle. Thought about
issuing a Cold Weather Advisory for this area, but held off as
wind chills will be marginal for a Cold Weather Advisory with
wind chills just touching -20F for a brief window.

Those heading out early on Monday will find a frigid morning as
temperatures are slow to warm. Sunny skies and light winds will help
conditions warm up during the afternoon hours. Highs will be warmer
than today, with temperatures hovering around average for late
December. Precipitation is not expected as upper-level ridging
begins to move onto the west coast.

.LONG TERM /TUESDAY 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 /06Z TAFS THROUGH 06Z TUESDAY/...
Issued at 1050 PM MST Sun Dec 28 2025

diminishing slowly overnight. Quiet weather expected on Monday to
start out the week.

HAZARDS/WEATHER TRENDS: VFR conditions will prevail over the next 24
hours with low impact weather. Remnant gusts of 25 knots out of the
northwest will end by 09z this morning.
