.SHORT TERM /THROUGH THURSDAY NIGHT/...
Issued at 255 AM MST Wed Mar 4 2026

With the upper-level shortwave responsible for yesterday`s
precipitation moving out, shallow ridging will build over the CWA
for mid-week. 700 mb temperatures under the ridge will warm to about
0C, leading to above average highs at the surface. Sunny skies will
help temperatures east of the Laramie Range climb into the 50s and
60s, which is about 10 to 15 degrees above average for early March.
Did bump high temperatures down west of the Laramie Range as snow
cover will likely lead to cooler conditions than what most models
are forecasting. Highs out west will most likely stay in the 40s
during the day. Subsidence under the ridge will keep precipitation
away. Expect calm and cool conditions Wednesday night.

Thursday will feature the last mild day of the week as warm air
aloft stays in place ahead of the next storm system. High
temperatures will roughly be the same as Wednesday, with highs in
the 50s and 60s east of the Laramie Range and 40s to low 50s west of
the range. Hi-Res guidance does show some showers developing during
the afternoon hours as the next upper-level trough swings into
Wyoming. Given then warmer temperatures in the afternoon,
precipitation is expected to start as rain. As the trough progresses
into the CWA overnight, precipitation will become more widespread
and ultimately transition to snow as the cold front moves across the
area.

.LONG TERM /FRIDAY THROUGH TUESDAY/...
Issued at 255 AM MST Wed Mar 4 2026

The main concern in the long term forecast will be an incoming
winter system as well as a return to windier conditions behind said
system. As mentioned previously, the trough and associated cold
front will move into the CWA Thursday night. As a result,
precipitation will become more widespread, with rain transitioning
to snow behind the front. Models still show some discrepancies
between each other, mainly with snowfall amounts. Positioning and
track of the surface low show similarities between cluster analysis
of the GFS and ECMWF ensembles. Based off current model data, most
snow will fall and accumulate during the day Friday. Snowfall totals
still need some ironing out, but it is likely that winter headlines
will be needed at least across southeast Wyoming. Prolonged
northerly flow will provide good upslope flow for places like
Laramie, Cheyenne, Rawlins and the Arlington area. This could lead
to higher snowfall totals in these areas. Accumulations are still
likely in Nebraska, but totals will be less than in Wyoming. Snow
will taper off Friday night.

Cooler temperatures are expected behind the system on Saturday.
This will definitely be true depending on the amount of snow
cover left behind. With the trough out of the area, drier
conditions are expected through the weekend and into the
beginning of next week. Warmer temperatures aloft will move in
by Sunday, leading to the return of above average temperatures
once again. The return of warmer temperatures will also see the
return of windy conditions. As winds turn more westerly, high
winds will become increasingly more likely for the wind prone
areas of southeast Wyoming Sunday through Tuesday. A pattern
change is possible towards the end of the long term which could
lead to cooler temperatures and a chance for precipitation.

.AVIATION /18Z TAFS THROUGH 18Z THURSDAY/...
Issued at 1020 AM MST Wed Mar 4 2026

will prevail for the duration of this TAF period. Winds, other than
KRWL, will remain generally less than 10 knots. Speaking of KRWL,
