.SHORT TERM /THROUGH FRIDAY NIGHT/...
Issued at 250 AM MDT Thu Jun 11 2026

Secondary cold front has recently pushed south into Colorado
late last night with some shower activity and embedded thunder
across western Nebraska at this hour. Pretty chilly airmass
behind this front, with temperatures continuing to lower into
low to mid 40s. High temperatures will remain near or slightly
below average for this time of the year with afternoon readings
in upper 60s to upper 70s under northwest flow aloft, warmest
over the lower elevations of western Nebraska. Remaining breezy
with winds shifting into the northwest with gusts up to 45 MPH.
Other than fire weather concerns, minimal impacts expected
through Friday night with dry conditions.

Pretty cold temperatures tonight with clear skies and pretty
good radiational cooling for mid June. Areas across the Laramie
Valley and the lower elevations of Carbon county may see low
temperatures by Friday morning nudging towards freezing, with
low to mid 40s possible across the eastern plains. Can`t rule
out some frost across the more sheltered valleys. Otherwise,
temperatures are expected to rebound Friday as low to midlevel
flow backs into the west and 700mb temperatures climb above 10c
to 14c. High temperatures Friday afternoon will generally be in
the 80s for most of the region, with a few locations below 4500
feet near 90 degrees.

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
Issued at 333 PM MDT Wed Jun 10 2026

Heading into the long term period, most of the CWA east of the I-25
corridor will have elevated fire weather concerns with dry
conditions continuing along with temperatures soaring into the mid
80s to mid 90s, warmest across the Nebraska Panhandle. This
coincides with minimum RH values tanking into the single digits by
Friday afternoon. A silver lining, winds don`t look to be all that
gusty, generally less than 25 mph. So, this may help in limiting any
fire spread for fires that are ongoing or if a new one begins. Then,
some changes are in store for over the weekend.

By Saturday evening, a 500MB shortwave takes a nose dive south, out
of Montana, into our CWA. This will bring a surface cold front that
slides across the region late Saturday into Sunday, increasing the
chances of precipitation along with bringing in a surge of cooler
air. Therefore, temperatures on Sunday will only top out in the mid
60s for many locations across the CWA, a tad cooler than what we`ve
been having as of late. This will bring an end to the fire weather
threat for the time being. The aforementioned shortwave rides on the
western peripheral of a deep trough that sets up over most of the
CONUS just to our east while a weak ridge tries to build to our
southwest. This keeps us under northwesterly flow which will bring
us a continuation of cooler temperatures through mid-week. Winds, as
of now, may pose minimal to no threat as the signal is weak within
most guidance. At the tail end of this forecast period, models are
hinting to a return of drier conditions along with a spike in
temperatures, stay tuned...
