...CRITICAL FIRE WEATHER AREA FOR SOUTHEAST COLORADO INTO PARTS OF
THE SOUTHERN HIGH PLAINS AND TEXAS SOUTH PLAINS...
...Morning Update...
No changes were made to the previous forecast. Elevated and Critical
fire weather conditions are still expected this afternoon as a
surface low emerges in the lee of the southern Rockies, promoting
strong westerly to southwesterly downslope winds and decreasing RH
atop a dry fuelscape. The OUN sounding this morning features a 45-50
kt jet just above the surface, and nearby observations across OK,
northwest AR, and southwestern MO are already portraying gusty winds
of 30-40 mph mixing down to the surface. Passing high clouds are
present and will remain spotty this afternoon, though these likely
won't constrict fire weather concerns across the broader area.
Please see the previous discussion for more information.

...Synopsis...
...Southeast Colorado into southern High Plains vicinity...
Stronger mid-level flow across much of the central and parts of the
southern Rockies will promote a deepening lee trough during the
afternoon and evening today. A moderately strong pressure gradient
across the terrain will drive 20-25 mph (locally higher) downslope
winds across these regions. RH during the afternoon will fall to
near 10% in some locations with around 15% being more common.
Continued lack of precipitation and dry fuels will support Critical
fire weather in the lee of the terrain and as far east as the Texas
South Plains. Farther south into the Trans-Pecos/Big Bend, lighter
winds (15-20 mph) are expected, though locally stronger winds may
occur within the Davis Mountains. Here, elevated fire weather
concerns are expected.
...Northwest Texas...Oklahoma...Ozarks...
Ahead of a surface cold front, southerly/southwesterly winds will
increase to 15-20 mph. Winds within the lowest 2 km will also be
strong and lead to gusty winds (up to around 35 mph). RH of 20-30%
is possible by the afternoon. There is some uncertainty as to how
low RH will fall given the expected mid/high level cloud cover
increasing through the day. Even so, dry fine fuels will support an
Elevated fire weather threat.

...CRITICAL FIRE WEATHER AREA FOR PARTS OF EAST-CENTRAL AND
SOUTHEAST NEW MEXICO...
...Synopsis...
...Central/southern High Plains...
Moderately strong northwesterly mid-level winds will be maintained
across the central and southern Rockies on Wednesday. Lee troughing
will extend across much of the central/southern High Plains. Dry
downslope winds of 20-30 mph appear possible in portions of
east-central and southeast New Mexico as stronger upper-level winds
nudge farther south and align with the peak of the cross-terrain
surface gradient. With at least some connection to the mid-level
moisture plume on the West Coast, high-level cloud cover and a
modest increase in surface dewpoints are possible. Guidance is not
overly confident in RH lower than 15% for more than a short period.
However, the enhanced winds at the surface will still drive a period
of Critical fire weather during the afternoon.
Elsewhere within the High Plains, RH of around 20% should be more
common. While 15-20 mph will occur in most locations,
terrain-favored areas could see speeds of 20-25 mph.
...Edwards Plateau into parts of central Texas...
As a modest surface low evolves south and east during the day, winds
of 15-20 mph will be possible. During the afternoon RH of around
15-20% can be expected. Lack of stronger winds will preclude a
greater fire weather risk, but Elevated fire weather is probable.

Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0348 PM CST Mon Feb 23 2026
Valid 251200Z - 031200Z
...Synopsis...
Mid-level flow will remain amplified over CONUS through the extended
forecast period. The predominant pattern will feature troughing over
the eastern US while strong mid-level flow continues across the
central US. Amplified ridging over the West will support strong
downslope flow and lee troughing over the Southern and Central High
Plains. This pattern will aid continued Elevated to Critical fire
weather conditions through the forecast period.
...Day 3/Wednesday - Southern Plains and Southeastern Colorado...
Fire weather conditions are expected to continue as a lee surface
low moves southeast across the Central Plains amid northwesterly
flow. Strong mid-level flow aloft will support broad downslope
northwesterly winds of 10-20 mph and RH values below 20% , so 40%
Critical probabilities have been maintained. 70% Critical
probabilities have been introduced where a localized area in
southeastern NM may experience stronger northwesterly downslope
surface winds of 20-30 mph atop dry, receptive fuels.
...Day 4/Thursday - South Central Texas...
As the surface low continues to shift south towards the Texas Gulf
Coast, a weak dry cold front will pass through South Central Texas
late morning/afternoon bringing dry and breezy northerly surface
winds. With low humidity and warm surface temperatures across the
area on Day 3/Wednesday, fine fuels will likely have dried out some,
leading to potential receptiveness to fire. 40% Critical
probabilities have been introduced to account for fire weather
concerns.
Beneath strong mid-level flow, tight surface pressure gradients
across central Wyoming may support strong downslope winds and low RH
in the lee of the Laramie Range into far western Nebraska on Day
4/Thursday and Day 5/Friday. However, with the potential for light
rainfall across the area on Day 3/Wednesday, fire weather highlights
have been withheld for now.
Model spread increases on Day 5/Friday through the remainder of the
forecast period regarding the overlap of dry and windy conditions.
Nonetheless, as the mid/upper-level pattern persists, fire weather
conditions will likely continue across portions of the Central and
Southern High Plains into the weekend.
