National Weather Service Cheyenne WY
302 AM MST Wed Nov 9 2022
.SHORT TERM...(Today and tonight)
Issued at 139 AM MST Wed Nov 9 2022
The active weather pattern continues across the area early this
morning as an initial cold front has pushed through from the
northeast, and has become stationary near the CO/NE/WY state
border. Further upstream, the potent longwave trough and
associated Upper Level Low is centered over western NE. This ULL
has become occluded, but the warm conveyor belt of moisture is
easily visible on the GOES Water Vapor satellite imagery as of
10Z this morning. Additionally, the cold front has caused some
surface forcing, and boundary layer moisture to the east of the
Laramie Range to increase. Surface observations in some locations
have decreased to 1 mile or less, thus have introduced patchy
dense fog into the short term forecast for the early morning
period.
The strong cold front further to the west will advance across
Wyoming today, resulting in snowfall west of the Laramie Range.
Localized QPF totals per the latest hi-resolution guidance over
the Snowy and Sierra Madre Mountain ranges increased slightly, so
have bumped up snow totals for both regions. This has resulted in
a new addition of the Winter Weather Advisory for the Snowy Range
as well. Additionally, the strong winds along and ahead of the
cold front is still expected as gusts up to 60-65mph are expected
for brief periods of time. With the cloud cover from the eastern
intrusion of cold air, and the western FROPA advancing eastward,
have gone with a reduction in MaxT for today, between 5-15
degrees. This will be noticed in the NE Panhandle where the cold
air will retreat temporarily today, but daytime highs will not
warm much altogether. The round of precipitation from the west
will advance over the Laramie Range this afternoon, resulting in a
switch from light rain showers to eventually an all snow
precipitation type by this evening. Areas across the Northern NE
Panhandle may see a light freezing rain/drizzle for a couple hours
near 0Z-3Z before transitioning to light snow showers. Overall,
the only region that will see moderate snowfall accumulation will
be the mountains. The remainder of the cwa will see light snowfall
accumulations.
Thursday into Friday, we will have much colder temperatures that
won't budge for the time being. Lingering clouds and light snow
showers will move out of the area by the late afternoon hours.
Blowing snow in the higher terrain is possible on Thursday. Daytime
highs in the 20s and 30s will quickly decrease late Thursday
night into early Friday morning. Most locations will see single
digits to lower teens for morning lows to start their Friday,
which is on the verge of 20 degrees below normal for this time of
November.

.LONG TERM...(Friday through next Tuesday)
Issued at 139 AM MST Wed Nov 9 2022
Long Range models continue to be in good agreement through the
weekend after the northern Great Plains storm system moves into
the Great Lakes region by early Friday. Model solutions then
start to diverge and are out of phase early next week as several
fast moving clipper-like systems dive southward out of Canada.
Models still indicate some pretty cold temperatures settling over
the region this weekend behind the Great Plains storm system,
with little, if any, warming behind it as 700mb temperatures
struggle to reach -2c on Sunday. Drier weather is expected Friday
through Sunday with highs mostly in the 30s and 40s. Saturday
might be the warmest day in the Extended portion of the forecast
with high temperatures in the 40s to near 50 across portions of
southeast Wyoming and the south/central Nebraska Panhandle.
Overnight low temperatures in the single digits and low/mid teens
will be widespread through early Monday morning, especially in
areas that end up with a light surface snowpack after the
Wednesday/Thursday event.
Models then show the fast moving upper level ridge axis quickly
weakening as north to northwest flow aloft becomes dominant over
most of the of the United States for early and mid next week. The
00z ECMWF is the only model showing some light snow associated
with a fast moving Alberta Clipper Monday night and Tuesday, with
the other models and 50% to 75% of the ensemble forecast members
remaining dry over Wyoming and western Nebraska. Bumped up PoP
across the area to mention a slight chance, mainly because this
pattern is favorable for off/on light snow shower activity.
Moderate to high confidence that temperatures will remain
significantly below average for this time of the year with highs
struggling to climb into the mid 30s.

.AVIATION...(For the 06Z TAFS through 06Z Wednesday night)
Issued at 1005 PM MST Tue Nov 8 2022
Early this morning until this afternoon we can expect widespread
IFR to LIFR cigs across areas east of the Laramie Range with the
possibility of dense fog until around 17Z. Cigs will begin to
lift late morning in southeast Wyoming, but stick around in the
Nebraska panhandle lifting to MVFR then VFR at some terminals between
17Z and 19Z. The next cold front bringing mostly snow showers and
gusty winds will begin moving across southeast Wyoming around 15Z
when snow showers will breach the KRWL area, impacts increasing
by 20Z. Through the afternoon, the primary impacts the rest of
southeast Wyoming and the Nebraska panhandle will experience will
be cigs lowering to IFR and potentially LIFR and gusty winds 25
to 35 knots.

.FIRE WEATHER...
Issued at 139 AM MST Wed Nov 9 2022
Fire weather concerns will remain low for most of the SE Wyoming and
NE Panhandle FWZs today. The only region that will be at a brief time
of elevated fire weather conditions is Laramie County in zone 430 from
the late morning to early afternoon hours ahead of a cold front moving
across the region today. Temperatures will be well below average for
the extended forecast period, leaving no additional fire weather issues.
