Area Forecast Discussion
National Weather Service Cheyenne WY
452 AM MST Sun Feb 8 2026

.KEY MESSAGES...

- A multi-day Red Flag Warning has been issued for the western
  Nebraska Panhandle and portions of southeast Wyoming through
  5PM Monday. Very dry conditions and gusty winds will combine
  to produce critical fire weather conditions in these areas,
  with relatively poor overnight humidity recoveries.

- High winds return to region tonight into Monday morning with
  wind gusts up to 80 mph possible.

- Progressive pattern expected through the week, with model
  uncertainty rising late in the period.

.SHORT TERM /THROUGH MONDAY NIGHT/...
Issued at 449 AM MST Sun Feb 8 2026

Mid-level water vapor shows a mostly occluded low moving southeast
into Northeast Wyoming and into South Dakota to slightly compress
our pressure gradient to give us breezy conditions through this
afternoon. Model soundings remain dry in the lower levels with more
moisture advecting in the mid to upper levels. No precipitation is
expected to develop from the system passing right past our forecast
area. Late tonight an upper level trough pushes across the
Canadian/US Border. This pushes a shortwave through the
Intermountain west tightening the 700mb pressure gradient even more.
The most severe winds look to be early in the morning as the 700mb
jet intensifies to 75 knots between 12 and 15z over the Northern
Laramie Range. Subsident flow also increases during this time to mix
down these faster winds to the surface. The 00z run for our in house
algorithm paints a 40 to 60 percent probability for Converse county
near Douglas and the Bordeaux wind prone area. It also paints a 60
to 80 percent probability of High winds for the Arlington and
Shirley Basin/ Muddy Gap area. To further the confidence of a high
wind event the Craig to Casper Height gradient also increases to
above 50 meters at 03z with peak height gradients near 70 meters at
06z. Later in the morning the 700mb jet looks to shift south
slightly placing weaker 50-60 knot winds over the Southern Laramie
Summit and Foothills area. With the GFS omega fields showing
sufficient subsident flow, its possible those winds could mix down
and develop high winds for the Summit and Foothill areas in addition
to the wind prone areas. The 700mb jet looks to shift back north
around 18z before decreasing in strength through the afternoon and
evening. Another reinforcing trough will push through the
Intermountain West. There looks to be a little moisture accompanying
this reinforcing trough to develop some precipitation chances early
Monday evening and into the overnight period.

&&

.LONG TERM /TUESDAY THROUGH SATURDAY/...
Issued at 449 AM MST Sun Feb 8 2026

Long term is a messy forecast period that starts with good model
agreement, but by the end of the period falls apart under a
progressive pattern that should see at least a few chances at
precipitation, albeit more rain or a mix into snow as
temperatures remain above normal. Monday begins as a the jet
sets in over the region for the day alongside a passing
shortwave. For winds, pressure gradients have continued to rise
across the region, while 700mb forecast winds are promoting a
70+ knot jet with a favorable and impressive downward forcing
component. In house guidance also favors high winds for our
wind prone locations, with probabilities up to 60-70%, leading
to highlights becoming likely for at least our usual locations.
Moisture begins to increase as this system moves across, and
while forcing won't be the best and downsloping does produce a
drier near surface layer moving further east of the mountains,
guidance is beginning to favor at least some scattered
precipitation extending into Tuesday with highest probabilities
for the mountains and intermountain region. Finally Monday
should be our last day of significantly warmer than average
highs, with 50's to upper 60's still possible for the day.

While temperatures will then drop moving into the middle and
end of the work week, without a strong cold airmass in the
region, we'll only see conditions drop back to several degrees
above normal, with another chance at 40's to 50's on Wednesday
in between passing systems. Analysis of models and their
ensembles show some agreement remaining through Wednesday and
Thursday as the transient ridge passes across with a Pacific
trough moving into the southwestern US, but by Friday guidance
falls off the rails again and ensembles are unsure on how to
resolve the multiple features we'll see influencing the forecast
area. For now, expectation is that we'll have our quick cool
down with a brief rise again on Wednesday, but moving into the
end of the week it becomes a bit more uncertain on how much of a
second cool down we'll see as the NBM shows anywhere from near
normal to 10 degrees above for the region, and how these systems
evolve also affects our precipitation chances. Nonetheless, it
appears that the strong ridging that we've been seeing for the
past several weeks may finally be on the decline, hopefully
allowing us to catch up on precipitation and, for those who
enjoy it, more winter-like conditions.

.AVIATION /12Z TAFS THROUGH 12Z MONDAY/...
Issued at 445 AM MST Sun Feb 8 2026

VFR Conditions will prevail through TAF period. Winds will
remain gusty through the day with winds dropping off around 00z
for our Nebraska Terminals. Low level windshear will develop
around 06z through the morning as a 700mb jet develops from a
passing shortwave. Winds will slowly increase through the
morning and the windshear will increase as well as the jet
strengthens. Shear between 40 to 60 knots will be possible after
06z for almost all the terminals.
