.SHORT TERM /THROUGH WEDNESDAY NIGHT/...
Issued at 154 PM MST Mon Dec 9 2024
Cloud cover continues to increase across the CWA this afternoon as a
cold front drops into the area from the north. With the frontal
passage, scattered snow showers are expected to develop this
afternoon. Snow showers will mainly be confined to Wyoming, however
would not be surprised to see some flakes in the northern Nebraska
panhandle. Will have to keep an eye on the snow showers this
afternoon, especially west of the Laramie Range. The RAP shows
about 100 J/kg of CAPE out in Carbon and Albany Counties by mid-
afternoon. Each new run of Hi-Res guidance that comes in shows
increasing values of the snow squall parameter. Although these
values are still moderate, the increased frontogenesis from the
cold front could lead to snow squalls this afternoon. The
limiting factor for squall development this afternoon will be
wind speeds. Guidance is not too keen on strong winds. However,
the HRRR is hinting at increased wind speeds within snow
showers. With these ingredients, would not be surprised to see a
snow squall or squall like shower or two. Shower activity will
wrap up this evening, but a stray shower could still be possible
overnight.
Another cold day is expected Tuesday as the upper-level trough that
brought the secondary cold front exits to the east. Expect
temperatures to be a few degrees below normal with highs in the
20s and 30s. Lingering cloud cover will add to the cold
temperatures, as well as the potential for a stray shower or
two, mainly east of the Interstate 25 corridor. High winds
return to the wind prones Tuesday evening. A strong surface high
will build over the Colorado Rockies with a strengthening
surface trough east of the Laramie Range. This will cause a
rather strong MSLP gradient to develop over and west of the
Laramie Range, leading to a gradient driven wind event. CAG-CPR
850 mb height gradients are also rather impressive, maxing out
at 80 meters late Tuesday night. 700 mb height gradients are
also within the range that would likely lead to high winds in
the Arlington/Elk Mountain zone. Winds aloft will be about 50 to
55 kts over the wind prones. Coupled with strong subsidence
over these areas and these winds will likely make it down to the
surface. In-house guidance is pinging the usual wind prones for
high winds with this coming event. It shows especially high
probabilities for the Arlington and Interstate 80
summit/foothills zones. As a result, did go ahead and issue a
High Wind Watch for these zones starting Tuesday afternoon and
continuing until Wednesday evening. Also issued a High Wind
Watch for Bordeaux, starting later Tuesday night and running
through mid-Wednesday afternoon.
High winds will continue into the day Wednesday, but gradually
weaken as gradients relax from a weak upper-level ridge over the
Great Basin. Winds will ease over the wind prones by the evening,
but blustery conditions can still be expected through Wednesday
night as winds aloft stay elevated. Aside from the wind, warmer and
drier conditions can be expected during the day Wednesday.

.LONG TERM /THURSDAY THROUGH MONDAY/...
Issued at 154 PM MST Mon Dec 9 2024
The upper level pattern remains rather tranquil in terms of
precipitation for the High Plains of SE WY and Nebraska
panhandle through the remainder of the week into the weekend. A
couple of the deterministic models (ECMWF/GFS) are showing a
slight perturbation moving through northern Wyoming on Thursday
which may trigger a trigger a few snow snow showers along an
elevated boundary near the northern fringes of Converse and
Niobrara counties, but with limited moisture it most likely not
bring much more than a dusting of snowfall. Another open upper
level wave is progged to quickly transverse across the area late
Thursday night into Friday. This feature initially shows a
pretty good fetch of Pacific moisture moving into western
Wyoming on Thursday night with even a hint of higher than normal
PWAT's for this time of year. However, this moisture quickly
dries out as it crosses the the higher terrain. It may be enough
to bring an inch or two to the Sierra Madre's on Friday
morning, due to some favorable upslope flow. However, the
700-500mb flow begins to turn more towards the west Friday which
will tend to limit accumulations. Temperatures will also be a
tad cooler (5-10 deg) on Friday as a frontal boundary crosses
the area.
This weekend still looks rather dry with the potential for some
weak upper level ridging. This will all be factored on the strength
of the upper level trof along the west coast. As a result, we
will continue to lean toward the blends in keeping temperatures
seasonably cool.

.AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/...
Issued at 431 PM MST Mon Dec 9 2024
Cold front well south of Wyoming and Nebraska this afternoon
with a brick north to northeast wind behind the front. These
winds will ease over the next hour or so. Strong winds return
Tuesday across southeast Wyoming and Nebraska Panhandle with
gusts 35 plus knots. Will need to keep an eye on lower ceilings
tonight in these northeast winds. For now...will keep lower
ceilings out of the forecast. But may need to amend TAFs if they
do occur.
