Area Forecast Discussion
National Weather Service Riverton WY
1041 AM MST Tue Feb 24 2026

.KEY MESSAGES...

- Mountain snow is forecast across western Wyoming Tuesday and
  Wednesday, with the heaviest snowfall rates between 5 AM
  Tuesday and 5 AM Wednesday. Mountains within Winter Storm
  Warnings have a 80 to 90 percent chance of one foot or more of
  snow.

- Western Wyoming valleys will receive precipitation Tuesday,
  but confidence has risen (70%) that snow will change over to
  rain in the afternoon and remain as rain through the overnight
  hours tonight. Rain will change back to snow by Wednesday
  afternoon, as the storm begins to wane.

- Very windy conditions continue along and east of the
  Continental Divide today, with the highest winds Tuesday
  occurring over South Pass/Red Canyon. Wednesday will be the
  windiest day of the week with widespread 35 to 45 mph wind
  gusts, and lower elevations of central Wyoming topping 50 mph.

&&

.DISCUSSION...
Issued at 158 AM MST Tue Feb 24 2026

Light snow has already started over northwestern portions this
morning. Snow will continue to increase through 12Z this morning,
becoming likely and spreading across the western mountains through
18Z. Gusty winds also continue for wind prone locations. Piney
Creek, near the Johnson/Sheridan County line, already gusted to 63
mph around 1130pm. Chief Joseph Highway is currently (as of 1225am)
blowing around 60 mph and had a 78 mph gust around 945pm. Wind gusts
of 40 to 50 mph are also occurring over South Pass/Red Canyon and
the south side of Casper. Due to the complex nature of this storm,
we will once again split the discussion between the snow and the
wind.

Snow...

The overall forecast remains on track will not many changes. Pacific
moisture from an atmospheric river (AR) will continue to move over
the Cowboy State today. Precipitable water (PWAT) values will
rapidly increase, with values of 0.35" to 0.4" becoming widespread
by 12Z this morning. This is well above the 90th percentile and
toward the climatological maximum. This, coupled with strong
isentropic lift, will lead to heavy snow. This afternoon looks to be
the period of the heaviest snow, with 2"/hr snowfall rates possible.
Snowfall totals of 18 to 24 inches is still in the forecast for the
mountains, with locally higher amounts up to 3 feet possible in the
Tetons. The forecast challenge continues to be the Jackson and Star
Valleys. However, guidance has shifted to snow changing over to rain
by early afternoon for both locations. Snow levels will be above
6000ft by this time and increase close to 7000ft before midnight.
Precipitation will change back to snow by midday Wednesday, as an
incoming Canadian system drops southward. Temperatures will
eventually drop back to freezing by mid to late afternoon, as snow
begins to end. Areas of ice will likely become a hazard Wednesday
night, as standing areas of water freeze overnight. Winds will also
increase Wednesday morning, as the main Canadian storm system drops
southward. Wind gusts of 35 to 55 mph will be widespread and the
snow will become drier (not as heavy and wet). This could lead to
very hazardous travel conditions over Teton/Togwotee Passes, as
blowing snow will lead to poor visibility conditions.

Wind...

Winds will decrease through the rest of the morning over the warned
areas with the threat for high winds (gusts of 58+ mph) ending
around sunrise. Thus, will likely expire the warnings for northern
Johnson County and the Cody Foothills. Wind gusts of 35 to 45 mph
will become more widespread by 18Z from southern Lincoln County to
Natrona County and continue through the afternoon. Additionally,
will extend the warning for Red Canyon/South Pass through 00Z. These
winds will decrease slightly after sunset, with gusts of 30 to 40
mph continuing through the overnight hours Tuesday night. The winds
over the Absaroka and Wind River Mountains will increase to 55 to 60
mph through the early morning hours Wednesday.

A Canadian system will rapidly drop southward across the forecast
area through the day Wednesday. Strong to high winds are still
expected across much of the CWA as a result. The main reason will be
due to a 140kt jet max associated with the PFJ and an elongated
vorticity axis that will shift southward across Wyoming. This will
translate to 700mb winds of 45 to 60kt, which will mix down to the
surface. Most areas can expect wind gusts of 40 to 60 mph through
the day on Wednesday, with winds increasing by 15Z. Will keep the
High Wind Watches in place for the Wind River Basin, Natrona,
Sweetwater and southern Lincoln counties. These winds will decrease
for most areas after sunset Wednesday evening, but gusts of 25 to 40
mph will continue through the overnight hours for wind prone
locations.

The gradient will remain tight enough across the CWA for wind gusts
of 30 to 45 mph Thursday afternoon from southern Lincoln County to
southern Johnson County, as well as over the mountains. Strong to
high winds look to return to the Clark areas and Chief Joseph Pass
Thursday night, as a tight temperature gradient of 10C at 700mb
develops along the east slopes of the Absarokas. This will result in
700mb winds increasing to 50 to 70kt, producing a significant gap
flow wind event. Will keep track of this possible event, as winds
could gusts as high as 80 mph. Otherwise, conditions are expected to
remain dry Thursday with above normal temperatures remaining in
place east of the Divide and over southern portions. Similar
conditions return for Friday, as models continue to keep the next
Canadian system to the north and only clipping northern
portions/Johnson County.

&&

.AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/...
Issued at 1024 AM MST Tue Feb 24 2026

West of the Divide...KBPI/KJAC/KPNA/KRKS Terminals.

A weather system will continue to bring rounds of precipitation
along with gusty winds to western terminals through the TAF
period. MVFR to IFR conditions will be periodic through at least
the first half of the TAF period at KJAC, KPNA, and KBPI.
Temperatures will play a role in determining impacts as warmer
temperatures are forecast to lead to some snow mixing or a full
transition over to rain. Showers will persist at KJAC, KPNA, and
KBPI through the early morning hours Wednesday. Some VCSH may
linger nearby KPNA and KJAC through the mid to late morning.
Winds will be gusting at KJAC this afternoon and evening with
speeds around 20 to 30 knots with some decreasing speeds for the
overnight. Winds return across all western terminals by the mid
to late morning hours Wednesday. Winds of 25 to 35 knots will
return to KJAC, KPNA, and KBPI with stronger gusts of 40 to 50
knots likely at KRKS by the end of the TAF period. Mountain
obscuration will prevail through nearly all of the TAF period
especially across western mountains.

East of the Divide...KCOD/KCPR/KLND/KRIW/KWRL Terminals.

The weather system entering the region will bring little to no
precipitation to terminals east of the Divide. KCOD, KWRL, and
KCPR may see some chances for showers near the end of the TAF
period. Otherwise the main concern will be strong gust winds
across nearly all terminals. Winds increase at KCOD and KCPR
through the afternoon and evening with speeds around 20 to 30
knots. Breezy winds persist across these terminals through the
overnight but will once again increase by the mid to late
morning Wednesday. Winds increase to 20 to 30 knots at KLND,
KCOD, and KWRL by the mid morning Wednesday. Stronger winds of
35 to 45 knots will develop at KRIW and KCPR by the end of the
period and continue through the end of the TAF period. Mountain
obscuration will be persistent over central and northern ranges
with periods of obscuration over more eastern ranges.

Please see the Aviation Weather Center and/or CWSU ZDV and ZLC for
the latest information on icing and turbulence forecasts.
