.SHORT TERM /THROUGH TUESDAY/...
Issued at 145 AM MST Sun Nov 15 2026

Current KCYS radar loop shows the sprinkles and flurries last
night dissipating early this morning as the poorly organized
Pacific storm system redevelops over the Texas and Oklahoma
panhandle...with any remaining energy with the northern portion
of the shortwave trough dissipating as well. Fog is still
observed across the high plains, mainly along the I-25 corridor
and the Cheyenne Ridge as it extends eastward into Kimball and
Sidney Nebraska. Otherwise, some light drizzle is possible in
this area, but should brief and end well before sunrise. Surface
winds are already starting to shift into the southwest over
Cheyenne with increasing winds out of the southwest expected for
the I-25 corridor from 100 AM to sunrise. Fog and low CIGS will
gradually lift with low clouds and fog remaining over the
Nebraska Panhandle and far eastern Wyoming until mid morning.
Kept the Dense Fog Advisory out for now, but may need to tweak
the areal coverage with fog expected to lift along I-25. Will
continue to monitor and adjust as need this morning.

For today and Monday, models show lingering morning cloud cover
early Sunday before give way to mostly sunny skies by the
afternoon with high temperatures trending back into the 50s to
low 60s. Portions of the western Nebraska Panhandle will likely
remain in the low 50s due to lingering low clouds. Even warmer
for Monday as a Pacific shortwave ridge axis translates eastward
into the Intermountain West and amplifies over the Front Range
Monday morning. Surface winds will remain out of the south as
the ridge axis moves into the Front Range, which is enough low
level upslope to hold onto some low clouds, and possibly fog,
Sunday night over Box Butte, Morrill, and Cheyenne Counties.
Further west, should be enough of a westerly wind component and
dry air intrusion to prevent fog development. Added some fog
into early Monday morning from Sidney to Alliance. Otherwise,
pleasant mid-November day expected with highs in the upper 50s
to mid 60s.

All models show the next Pacific storm system rapidly moving
onshore, producing rainfall as far south as southern Calif and
mountain/Great Basin snowfall Tuesday. This will be our next
weather maker which is forecast to impact the region late
Tuesday and Wednesday. As of right now, models are not
indicating a closed storm system and still show an open wave
trough ejecting northeast over Wyoming and Montana. This storm
track favors mountains snow, cooler temperatures, and windy
conditions across southeast Wyoming (strong winds possible
across the wind prone areas). Will continue to monitor this
system over the next few days.

.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
Issued at 129 PM MST Sat Nov 14 2026

The majority of the long term will feature relatively benign weather
with a return to more seasonable temperatures and breezy
conditions.

A pattern change will arrive on Wednesday as a
trough swings into the Rockies. A cold front will move across
the area, late Tuesday night or early Wednesday morning, leading
to high temperatures in the 40s and 50s--roughly average for
this time of year. This front will be mostly dry, with
predominately west winds promoting a dry downslope environment.
The mountains, however, could see a quick shot of snow, with the
Sierra Madre Range picking up a few inches of accumulation. The
Snowys will likely be shadowed and not see much in the way of
accumulations. The bigger concern with the frontal passage will
be strong winds. Marginal high winds will be possible as MSLP
gradients compress from the front. Winds aloft will increase up
to about 50 kts with decent subsidence, so cannot rule out 60
MPH gusts during the day in the typical southeast Wyoming wind
prones.

Seasonal temperatures will stick around on Thursday with little to
no weather impacts expected. Some lingering breezy conditions are
still likely west of the Laramie Range on Thursday, but the rest of
the forecast area will see a quiet day. Friday into the weekend,
things could get interesting with a potential impactful winter
storm. Of course, its still over a week away with plenty of time for
models to come to a solution, but there is a chance for accumulating
snow and windy conditions.

.AVIATION /18Z TAFS THROUGH 18Z MONDAY/...
Issued at 1045 AM MST Sun Nov 15 2026

Low stratus and fog are gradually clearing out of the southeast
Wyoming and western Nebraska late this morning. Once clouds
dissipate, mostly sunny skies are expected for the remainder of the
day with breezy conditions. Fog and low stratus are likely to return
to western Nebraska terminals once again early Monday morning.
