.SHORT TERM /THROUGH TUESDAY NIGHT/...
Issued at 309 PM MST Mon Nov 2 2026

Snow began earlier this morning for areas west of the Laramie Range.
Webcams and surface observations confirmed the snow, which was
accumulating on grassy surfaces under pretty decent snowfall rates.
Precipitation rates in these areas have begun to lessen as the
surface low tracks further to the northeast, allowing some of the
snow to melt thanks to the warmer ground temperature. The surface
low tracking to the northeast is also producing some impressive wind
gusts for areas east of the Laramie Range. Frequent gusts of 50 MPH
are being observed. These strong gusts will continue into the
evening hours, with the potential for an occasional 60 MPH wind gust
through that timeframe. After midnight, winds will weaken, but still
be quite blustery. Precipitation is beginning to fill in a bit more
east of the Laramie Range. Temperatures here are predominately in
the 40s so rain is still being observed. As snow levels drop to
about 5000 feet this evening, rain will transition to snow, with the
potential for accumulation, mainly along the Pine Ridge from the
Niobrara/Converse County line to the Sioux/Dawes County line. Went
ahead and issued a Winter Weather Advisory for Niobrara County as
Lusk and the hills south of town could see between 2 and 4 inches of
snow this evening and into tonight. Will also have to keep an eye on
Harrison as they also have the potential to pick up a few inches of
snow. The other area of concern will be the northern edge of the
Cheyenne Ridge. Newer model guidance keeps placing several inches of
snow here, however uncertainty is still high with amounts as it will
largely depend on the snow levels. For now, will keep an eye on this
area to see if any short-fuse winter headlines are needed. Other
Winter Weather Advisories remain on track, with snow tapering off
around the Arlington area this evening when the Advisory
expires. The mountain zones and the South Laramie Range are also
on track, with snow expected to continue through this evening,
with additional accumulations up to 4 inches depending on location
and elevation.

The weather on Tuesday looks quieter as the surface low pushes out
of the area. Some lingering precipitation and wind could still be
possible in the Nebraska panhandle during the morning hours, but
will taper off by the afternoon. Decreasing clouds are expected
throughout the day with mostly sunny skies anticipated by the
afternoon. The increased sunshine will lead to warmer temperatures
with highs in the 40s and low 50s. However, temperatures could be
cooler based on the amount of snow cover.

.LONG TERM /WEDNESDAY THROUGH MONDAY/...
Issued at 309 PM MST Mon Nov 2 2026

Wednesday...Our region will be in between weather disturbances with
a trough aloft over central Colorado, producing some cloud cover
over our counties, but no precipitation. Temperatures slightly
warmer than Tuesday with 700 mb temperatures near 0 Celsius.

Thursday...High amplitude and well pronounced ridging aloft will
prevail across our counties, keeping the weather dry. The warming
trend will continue, and with 700 mb temperatures near 2 Celsius,
yielding maximum temperatures mainly in the 50s.

Friday...A progressive and positively tilted shortwave trough aloft
moves across eastern Montana and eastern Wyoming, though with little
if any cloud cover and no precipitation for our forecast area.

Saturday...Brisk northwest flow aloft prevails, and with decent low
level pressure gradients, look for a windy and blustery day. Maximum
temperatures should be slightly cooler than Friday.

Sunday...Transitory ridging aloft moves across our counties, with
significant height rises aloft. 700 mb temperatures near 6 Celsius
will yield high temperatures from the lower 50s to lower 60s.

Monday...The slow warming trend continues as the flow aloft backs to
westerly and with little if any cloud cover and 700 mb temperatures
near 5 Celsius suggesting maximum temperatures from the upper 50s to
mid 60s.

.AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/...
Issued at 444 PM MST Mon Nov 2 2026

An elongated surface low pressure system spanning the Great Plains
will bring a variety of hazards over the next 24 hours including
rain and/or snow, gusty winds, and low CIGs/vis.

For winds, can expect gusty conditions overnight mainly east of the
Laramie Range with NW gusts as high as 40-45 knots in the presence
of a strong leeside pressure gradient. Expecting precipitation to
become more widespread this evening into the overnight hours
especially across the Panhandle, where prevailing groups for -RA
were put in the TAFs with primarily IFR expected before 12Z as this
storm system exits our area tomorrow after sunrise. Introduced TEMPO
groups for KCYS and KLAR for snow, or a mix of rain and snow this
evening as current radar reflectivity shows has somewhat of a banded
appearance and thus moderate confidence that both terminals will be
impacted by precipitation. Expect mainly some lingering showers for
the SE WY terminals until 09Z, so kept in PROB30 groups until then
after the most widespread precipitation is expected to be located
over our NE terminals. CIGs are expected to lift to at least
MVFR criteria from west to east by 15Z, with a gradual clearing
trend expected throughout the day Tuesday.
