What forecasters said that day
The local office's own words before this high wind warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Cheyenne, WY wrote its last area forecast discussion before this high wind warning went out at Apr 21, 10:50 PM MDT, 2 hours 40 minutes earlier. Its key messages:
- A Red Flag Warning remains in effect for all areas east of the Laramie Range until Wednesday evening as critical fire conditions are expected.
- There is a Marginal Risk (Level 1 of 5) for severe weather Wednesday afternoon. The primary concerns will be damaging winds gusts caused by microbursts.
- The potential for high winds will return Wednesday afternoon into Thursday. This may event spread outside of the wind prone areas. A High Wind Watch has been issued for Wednesday afternoon through Thursday evening.
- A cooler weather pattern with more frequent chances for precipitation will take over Thursday and last into early next week.

.SHORT TERM /THROUGH THURSDAY NIGHT/...
Issued at 316 PM MDT Tue Apr 21 2026
The apex of the upper level ridging is just about centered over the
Intermountain West. This ridging has help facilitate our mostly
clear skies and drier air being pumped towards the surface. Looking
across the Southeast Wyoming and Nebraska Panhandle area winds
remain rather light with RH values being around 15 percent or less
across the forecast area. As this ridge pushes off this evening an
upper level trough will slowly push eastward from the Pacific
Northwest and along the Canadian border. The pressure gradient is
expected to increase as the trough pushes into the region as well as
the dry line moving through. High winds look to start Wednesday
morning and last through the evening Thursday. WInds in and along
the wind prones look to possibly reach up to 80 mph as the 700mb jet
increases to around 70 to 75 knots late Wednesday night into early
Thursday morning. With the increasing downsloping winds Wednesday
afternoon into Thursday, its questionable as to whether the dryline
will have any moisture to lift considering the RH values being so
low. If any showers do develop along the dryline then the highest
threat would most likely be a dry microburst type setup where
precipitation falls out of the cloud and evaporates before hitting
the ground, however the weight and pressure displaced by the
precipitation is still moving towards the ground causing and
increase in wind gusts in all directions from the center point of
where this column of weight and pressure impacts the ground. The
high winds will continue into Thursday as the upper level trough
continues to push through the Intermountain West and into the
Northern Plains. There is a little bit of moisture being advected
into the region along the trough axis as it pushes eastward. The
highest chance for any measurable precipitation is in the mountains
and lower elevations of Carbon county. The dry layer near the
surface will be reinforced by the high winds east and along the I-25
corridor thus limiting the amount of any measurable precipitation
hitting the ground in the lower elevations. As the high winds start
to die down Thursday afternoon the precipitation chances will start
to increase for the lower elevations east of I-25. Even though most
of the forcing looks to be contained in the Dakota's, there are a
couple vort maxes that lagged behind the main trough and increase
the amount of synoptic forcing for our area. By Thursday evening the
High winds should be done but we will have lingering strong gusts
along I-80 and in our wind prone areas. Overnight Thursday, another
shortwave will push into the Intermountain West giving greater
precipitation chances across the forecast area moving into Friday
morning.
&&
.LONG TERM /FRIDAY THROUGH TUESDAY/...
Issued at 316 PM MDT Tue Apr 21 2026
As we head into the long term period, one thing will be very clear,
the air will feel a little crisper on your skin. Expect temperatures
to be and remain near normal, believe it or not, with highs topping
out in the 50s across southeast Wyoming and low to upper 60s in the
Nebraska Panhandle. Not only this, but we will be in an active
pattern, so precipitation chances will be elevated compared to what
we've been seeing as of late. Why, well, more on that in a bit.
Hopefully this increased chance of precipitation will make a dent in
the extreme drought (U.S. Drought Monitor) we are in and cut down
our fire weather threat. So, what is different this time around?
Well, the main player in this forecast period will be a robust upper-
level low that becomes parked over Saskatchewan with a trough
stretching south into our region. This will allow vort maxes, pulses
of energy, to feed into our CWA and kick start that increased
precipitation chance. As we progress into and through the weekend,
this upper-level low will remain quasi-stationary over Saskatchewan
through at least Monday. Thereafter, it will move off to the east
and weaken as a weak transient ridge builds across our CWA, drying
us out briefly.
What are the probabilities of seeing at least 0.10" of
precipitation? Well, there will be a weak system that slides in
Friday and ensemble guidance has probs remaining relatively low
across the CWA. However, there will be another system over the
weekend into early next week that will give us a better chance.
Probs with this one are in the 60 to 80% range of seeing 0.10" of
liquid precipitation. Most locations will see primarily rain, but in
the higher elevations this rain may mix with snow or remain all
snow, with amounts still needing a bit of ironing out. Winds in the
long term will not be much of a concern with meager mid-level
support. Friday morning has our best chances with a 50 knot 700MB
jet sliding in. Per GFS, omega will be lacking so these winds may
not mix down to the surface.

.AVIATION /06Z TAFS THROUGH 06Z THURSDAY/...
Issued at 1050 PM MDT Tue Apr 21 2026
Relatively light winds this morning as high pressure aloft slowly
ejects eastward into the plains. A cold front and associated upper
level trough will then push into Wyoming late this morning and
afternoon. Increasing winds and cloud cover expected after 15z
Wednesday with some stronger wind gusts possible.
HAZARDS/WEATHER TRENDS: VFR conditions will continue over the next
24 hours due to a very dry airmass near the surface. Winds will
begin to increase from west to east between 11z and 19z,
respectively. Gusts between 35 to 45 knots expected for the
southeast Wyoming terminals, and between 30 to 40 knots for western
Nebraska. Winds should remains this strong for all terminals through
Wednesday night with wind direction shifting into the west or
northwest. Can't rule out a shower or thunder-shower for KSNY, KAIA,
and KCDR Wednesday afternoon, but confidence and coverage are pretty
low at this time (~5% chance). Strong erratic gusty winds are
possible with any nearby shower.
