.SHORT TERM /THROUGH MONDAY/...
Issued at 101 PM MST Sun Dec 21 2025

The biggest story in the short term will be, one word, wind.
Yep, the winds are back, so enjoy the calmness while you can.
The surface gradient will tighten across the higher terrain
while a lee-side trough develops along the I-25 corridor. This
combined with a 65-70 knot 700mb jet and appropriate subsidence
will cause the winds to really ramp up this afternoon, especially
in the wind prone areas along I-25 and I-80. In these locations,
expect southwest winds 30-50 mph with gusts up to 75 mph, and
as a result, High Wind Warnings are in effect for Bordeaux,
Rawlins, and the Laramie Summit/Foothills from 2pm this
afternoon through 2pm Monday. Thereafter, the winds will wind
down through the overnight hours into Tuesday. The apex of the
winds should not reach the Nebraska Panhandle. Now with the wind
talk out of the way, lets look at some other stuff. Precipitation
chances across the CWA will practically be nil with an upper-
level ridge building, in fact, for a sneak peek at the long
term, minimal precipitation chances will prevail through mid-
week. What about temperatures you may ask, well, with a ridge
building in that means one thing, a warming trend. Highs today
should top out in the upper 40s to near 60, warmest east of
I-25, while lows tonight dip into the mid 30s to mid 40s. Get
out those beach shorts and flip-flops, highs Monday will soar
into the mid 50s to near 70, warmest across the Nebraska
Panhandle, while lows bottom out in the 30s.

.LONG TERM /MONDAY NIGHT THROUGH SUNDAY/...
Issued at 101 PM MST Sun Dec 21 2025

The long term forecast is mainly dominated by an upper ridge
pattern centered over Eastern Texas for the most part. An
amplified ridge axis will move over the Intermountain west
calming down the winds. The winds will be quite weak compared to
the previous week but still maintain a slight breeze Tuesday
into Wednesday. 700mb temperatures are expected to raise from
the 3 to 4C range on monday into the 5 to 6C range on Tuesday
into Wednesday. This slight increase in 700mb temperatures will
lead to surface temperatures to bu in the 50`s west of I-25 and
into the 60`s east of I-25 to continue this warm pattern. There
is a slight disturbance in the Upper levels come Wednesday
afternoon into Thursday (Christmas). Wednesday afternoon, the
upper level low dives down the Pacific Coastline sending a
shortwave across our ridge along the Canadian Border. The
shortwave will produce a cold front across Southeast Wyoming and
the Panhandle producing some possible snow showers for the
mountains and and a rain/snow mix for the adjacent areas west of
I-25. Ensemble guidance continues to be in agreement about the
surface temperatures being in the high 50`s if not breaking 60
for areas east of I-25 come Christmas day. So hopes for a white
christmas look very slim. Christmas Day and Friday does look to
be breezy as that shortwave moves across the Canadian
Providences however, the models have trended towards a weaker
jet throughout the day Thursday so its still a little bit
uncertain if we will need a high wind warning for that time
period. Our in house algorithm only gives Arlington a 40 to 60
percent chance of reaching high winds Christmas day. But the
winds will definitely be elevated and we have strong subsident
flow over the I-25 corridor for possible mountain wave activity.
The weekend looks to be a like cooler and more seasonable as
700mb temperatures cool back into the negatives for temperatures
possibly in the 40`s and 50`s.

.AVIATION /06Z TAFS THROUGH 06Z TUESDAY/...
Issued at 1031 PM MST Sun Dec 21 2025

VFR conditions expected for the forecast period. Gusty southwest winds
continue at KLAR and KRWL overnight and through the day Monday,
with occasional lulls possible. Expect LLWS when the surface
winds are light. LLWS will also be a concern through mid morning
at all other terminals with strong west to southwest winds just
above the surface. Look for gusts to around 50 knots Monday at
KRWL, with gusts of 35 to 45 knots possible for KLAR and KCYS.
Nebraska terminals can expect gusts between 20 and 30 knots.
