.SHORT TERM /THROUGH TUESDAY NIGHT/...
Issued at 151 PM MST Mon Nov 9 2026

Benign weather continues in the short term with mostly sunny skies
and mild temperatures expected for the remainder of Monday
afternoon. Quiet conditions will carry on into the overnight hours,
with low temperatures once again staying on the mild side for early
November.

The weather gets *slightly* more exciting on Tuesday. A dry upper-
level shortwave will move into the CWA from the northwest bringing
with it wind and some cloud cover. MSLP gradients will tighten along
and west of the Laramie Range, helping to increase winds aloft. 800
to 700 mb winds will max out around 40 kts with decent subsidence
over the typical wind prone areas of southeast Wyoming. Gusts up to
50 MPH can be expected, with an occasional gust to 55 MPH possible.
In-house guidance gives about a 40 percent chance of high winds at
Arlington, Bordeaux, and the South Laramie Range, however, marginal
events like this tend not to verify in El Nino conditions. The
shortwave will also bring increased cloud cover, likely in the form
of high clouds and some mountain waves from strong winds. The windy
conditions will also lead to a warm day across the eastern half of
the CWA. Downsloping winds will help raise temperatures into the 60s
and low 70s, which is about 10 to 15 degrees above average for this
time of year. Winds will ease during the evening hours, once again
leading to quiet overnight conditions.

.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
Issued at 151 PM MST Mon Nov 9 2026

Wednesday...Dry northwest flow aloft prevails, with slightly cooler
temperatures compared to Tuesday based on 700 mb temperatures.
Breezy to windy conditions based on the low and mid level gradients.

Thursday...As a ridge aloft moves further eastward across Wyoming
and 700 mb temperatures rise to near 6 Celsius, a warming trend will
begin with high temperatures from the upper 50s to upper 60s.

Friday...Ridging aloft moves overhead centered from western North
Dakota to eastern Colorado, with maximum temperatures similar to
those of Thursday.

Saturday...A progressive negatively tilted shortwave trough aloft
moves into western Wyoming, spreading increasing mid and high level
cloudiness across our counties, with low POPS across southern Carbon
County, for rain and snow showers, including the Snowy and Sierra
Madre Ranges. Slightly cooler with the increase in cloud cover.

Sunday-Monday...West to southwest flow aloft prevails, and with
minimal low and mid level moisture, chances for precipitation will
be limited. Maximum temperatures will be similar each day, from the
mid 50s to mid 60s.

.AVIATION /06Z TAFS THROUGH 06Z WEDNESDAY/...
Issued at 1040 PM MST Mon Nov 9 2026

A potent upper level trough across the Pacific Northwest will
quickly move eastward into the high plains Tuesday afternoon. Dry
conditions will continue with intervals of mid to high clouds. Windy
conditions expected ahead of this trough for all terminals late
Tuesday morning through Tuesday afternoon.

HAZARDS/WEATHER TRENDS: VFR conditions will continue through Tuesday
afternoon. Winds will be the primary Aviation concern with west to
northwest winds increasing by 16z to 18z. Wind gusts between 25 to
35 knots after 17z, highest gusts across the southeast Wyoming
terminals.
