.KEY MESSAGES...
- The long duration wind event continues, with wind gusts
expected to peak today. While some breaks or lulls will occur,
high winds will be a concern every day through Saturday.
- Damaging winds are expected near and in the lee of southeast
Wyoming mountain ranges through Tuesday afternoon. Gusts up
to 90 mph are expected.
- Cheyenne, Laramie, Rawlins, Wheatland, and Douglas can expect
wind gusts up to 75 mph through the day today.
- Wind gusts up to 65 mph are expected to spread into High
Plains mid morning into the afternoon.
- A cold front will bring a banded rain and snow showers late
this afternoon through the evening. This will also bring a
brief reprieve from the wind into Wednesday morning.

.SHORT TERM /THROUGH WEDNESDAY NIGHT/...
Issued at 415 AM MST Tue Dec 9 2025
Current GOES satellite imagery shows plentiful mid to upper level
cloud cover racing inland across the northwest CONUS towards our
area this morning. The powerful 150 knot jet streak aloft is nosing
into our area this morning, supporting the ongoing high wind event.
A strong upper level shortwave is riding along the north side of the
jet streak, but has developed a potent lee cyclone over the Canadian
Prairie. A surface trough trails south of this feature down to our
area, which is dropping surface pressure over our plains and
enhancing the MSLP gradient across the barrier. We have already been
seeing gusts to around 75 mph in the typical wind prone areas so far
this morning, but it is really just beginning. Gradients are
expected to continue to climb through the morning, maximizing
between about 9AM and noon or so. The plentiful cloud cover moving
in makes it a little difficult to ascertain how much mountain wave
activity is ongoing via satellite imagery, but forecast models
continue to show a stable inversion layer developing around the
mountain top height this morning. This should promote increasing
mountain wave activity and wave breaking into the early afternoon
hours. These breaking waves will be what will be needed to realize
the 80 to 95 mph gust potential from this event. Overall, the event
looks on track. As we head into the late morning and afternoon
hours, 50 to 60 knot winds at 700-mb will spread over the High
Plains. Forecast soundings show fairly well mixed boundary layers
developing for a few hours during the afternoon, which should help
mix these winds down to the surface and get the strong winds
spreading into the Nebraska panhandle.
The temporary reprieve from the wind is also still on track for
this evening. The aforementioned upper level shortwave trough
will race eastward this afternoon. Behind it, surface high
pressure will fill in over the plains just in the lee of the
Rockies. The front will reach our northernmost forecast zones by
mid afternoon (a slight acceleration from previous forecast
packages), reaching Cheyenne around 8PM or so. Once pressure
starts rapidly rising over the plains, we should see a rapid
drop off in the high winds across the area. That's not to say it
will be calm, as the front will be accompanied by 35 to 50 mph
northwest wind gusts, but the potential for 60+ mph winds will
likely decrease behind the initial gusts along the front. We
might have a gap even in the wind prone areas beginning around
midnight. In addition to the break from the wind, this front
will bring a brief window of lift and increased moisture
content. Expect to see some banded rain and snow showers
developing north of the North Platte River valley between 2PM
and 5PM, then spreading south to the I-80 corridor this evening.
Neither the lift nor the moisture looks impressive by any means
though, so forecast precipitation totals are modest at best.
That being said, these are expected to organize into a banded
structure along a temperature gradient, so there is the
possibility for quick visibility reductions. Temperatures will
be shockingly warm ahead of this, such that most of the activity
could be rain. However, confidence in remaining all rain is not
very high, and this is worth a discussion since a flip to snow
could certainly cause travel problems. In the mountains, moist
orographic lift will resume midday today, and continue into
Wednesday morning. The higher peaks could pick up several more
inches of snow accumulation, so a Winter Weather Advisory has
been issued.
The surface high will translate across the area into Wednesday
morning. By around sunrise though, expect to see surface pressure
falling once again right along the crest of the Laramie Range. Wind
speeds will pick up again first in Carbon and Albany counties, and
then gradually spread eastward through the afternoon. This time, the
surface trough is not expected to advance much further east than I-
25, which should confine the second phase of this high wind threat
to southeast Wyoming along and west of I-25. Pressure and height
gradients will be impressive once again, but probably won't get
quite as high as they are expected to today. Therefore, the wind
gust potential during phase two Wednesday afternoon and Wednesday
night is not quite as high, but still at least a middle tier high
wind event for our area. Currently, we are looking at another round
of 70 to 80 mph gusts for the wind prone areas, and 60 to 70 mph
gusts spreading into the adjacent zones. This will continue into
Wednesday night and possibly Thursday. With this forecast package,
the High Wind Watch for the remaining wind prone areas was upgraded
to a warning and extended out through Thursday night. The other
watches in southeast Wyoming were left as is with this update,
mainly due to uncertainty in the end time of this phase of the
event. Since we are still 30 hours or more away from the start of
phase 2, we can let the watch continue for another cycle to get some
better precision on the end time.
&&
.LONG TERM /THURSDAY THROUGH MONDAY/...
Issued at 415 AM MST Tue Dec 9 2025
Active northwest flow will continue into the upcoming weekend,
creating forecast headaches all through the period. Expect the upper
level ridge to amplify on Thursday, nudging the baroclinic zone and
associated stationary front off to our northeast. Mild temperatures
will flood into the area south of the boundary. Another shortwave
trough aloft will pass north of the area sometime Thursday or
Thursday night, and this will be followed by a surface high, wind
shift, and cold front. This should nudge the stalled frontal
boundary back to the southwest into Friday morning. Ensembles have
come into better agreement keeping most of the frontogenesis off to
our northeast Thursday night and Friday, but PoPs still creep into
our northern and eastern zones. The front will also do the same
thing as tonight's front and pause the high wind threat temporarily.
Unfortunately, model guidance has recently been trending more
aggressive with winds Friday into early Saturday as the ridge
fluctuates overhead once again. While forecast uncertainty remains
considerable during this period due to our proximity to the arctic
front, it is looking more likely that we may have to tack on another
day or two to this very long streak of high winds.
&&
.AVIATION /12Z TAFS THROUGH 12Z WEDNESDAY/...
Issued at 441 AM MST Tue Dec 9 2025
Very strong winds will impact aviation through the forecast
period. This morning, expect significant LLWS at all terminals.
Wyoming terminals are already seeing gusts approaching 50 knots,
which will continue through much of the day. Gusts may exceed 60
knots mid morning into the early afternoon. In Nebraska, gusts
will gradually increase this morning with potential for gusts
between 40 and 50 knots between about noon and sunset.
A cold front will sweep southward beginning with CDR around 21z
and reaching CYS and LAR last 03z. Expect to see winds shift to
the northwest behind this boundary. In addition, scattered
banded rain and snow showers will be possible along and for
about 2-3 hours after the frontal passage. Brief IFR could occur
especially at RWL and LAR where precip type is more likely to be
snow. In Nebraska, rain is the more likely precip type, but a
quick shot of snow cannot be ruled out. Most terminals should
get a break from the wind after midnight.
