Day 1 Fire Weather Outlook

0112 AM CST Sun Feb 08 2026
Valid 081200Z - 091200Z
...Synopsis...
Broad upper ridging will overspread the western and central CONUS
today, with multiple pronounced, embedded impulses poised to
traverse the upper ridge through the day. One mid-level impulse,
accompanied by a 70 kt 500 mb jet streak, will overspread the
northern Rockies, encouraging surface low development north of the
Canadian border, with lee troughing expected over the High Plains.
The strongest westerly surface flow is likely over eastern Montana
(i.e. 15-25 mph), in closer proximity to the surface low. However,
RH will likely remain too high for Elevated highlights, though the
stronger winds and drying fuels may promote localized wildfire
spread potential. The better chance for Elevated fire weather
conditions will be along the Wyoming/Colorado/Nebraska border. Here,
15+ mph sustained west-northwesterly surface winds may overlap with
RH dipping to 20 percent for a few hours Monday afternoon, atop
drying fuels that have not received any precipitation for at least a
few weeks.
Localized wildfire potential exists over the Florida Peninsula,
where dry fuels and 20-35 percent RH are expected Sunday afternoon.
However, the lack of an appreciable surface wind field precludes
fire weather highlights.

...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE SOUTHERN HIGH
PLAINS...
...Synopsis...
A mid-level trough will overspread the Great Lakes as another upper
trough impinges on the California coastline tomorrow (Monday). The
progression of the northern U.S. trough will encourage surface low
development over the central Plains Monday afternoon, with dry
downslope flow over portions of the High Plains. Widespread Elevated
conditions are expected across parts of the central High Plains into
Nebraska immediately behind a surface cold front accompanying the
aforementioned surface low. 15-20 mph sustained west-northwesterly
surface winds will overlap with 20-25 percent RH atop dry fuels for
at least a few hours.
Farther south across the southern High Plains, dry downslope flow
will be stronger compared to points farther north. By afternoon peak
heating, southwesterly surface winds may sustain over 25 mph amid
10-15 percent RH, warranting Critical highlights given dry fuels.

Day 3-8 Fire Weather Outlook

Mid-level flow over the CONUS is forecast to intensify and shift
southward as upper troughing over the East weakens. As stronger
zonal flow aloft becomes established, several shortwave
perturbations will move over the Rockies and into the Plains next
week. Periods of stronger westerly flow will likely support more
active fire-weather conditions in the High Plains early next week.
general amplification of the pattern should continue into next
weekend, likely with an increase dry conditions and fire danger over
the central and Southwestern US.
...High Plains...
Several perturbations within the increasingly zonal flow regime will
pass over the Rockies next week. A southern stream trough moving out
of northern Mexico will allow for modest lee cyclogenesis D3/Monday
over parts of NM and southern CO. Dry and breezy downslope
conditions are possible south of the low with RH below 20% expected
across portions of eastern NM and west TX D3/Monday. This will
likely support a few hours of elevated fire-weather potential
despite fuels that are only modestly receptive to fire spread.
Farther north into parts of the central High Plains, a stronger
upper trough will move over the northern Rockies also supporting
strong downslope winds. A surface cold front will also move south
bolstering surface winds over parts of CO/WY and NE. Downslope winds
of 20-30 mph are possible. However, uncertainty exists on how dry
surface conditions will be given the cooler temperatures and cloud
cover associated with the front. Still, unusually dry fuels and a
few hours of strong winds and lower RH should support elevated
fire-weather conditions D3/Monday.
Episodic troughing will continue over the Rockies and Plains next
week with the overall pattern gradually amplifying into next
weekend. Ensemble spread increases by mid week but does hint at
strong troughing and increasing fire-weather potential into week two
across the Plains and Southwest. For now confidence in dry/windy
conditions and the return of Gulf Moisture/precip precludes any
additional probabilities.
