Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1148 PM CDT Tue Mar 31 2026
Valid 011200Z - 021200Z
...Synopsis...
A mid-level trough will eject into the Plains states today, with a
surface low expected to develop in Kansas by afternoon. Gradient
flow due to surface low intensification, along with some downslope
component of flow, will foster windy and modestly dry conditions
across the southern High Plains. The latest guidance consensus shows
widespread west-southwesterly surface winds exceeding 20 mph amid 20
percent RH across eastern New Mexico into western Texas, warranting
Elevated highlights. Widespread clouds and potential showers will
hinder widespread Critical conditions, though locally Critical
conditions are possible.

Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1158 PM CDT Tue Mar 31 2026
Valid 021200Z - 031200Z
...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF SOUTHEASTERN COLORADO
INTO NORTHEAST NEW MEXICO...WESTERN TEXAS PANHANDLE...WESTERN
OKLAHOMA PANHANDLE...AND FAR SOUTHWESTERN KANSAS...
...Synopsis...
A second mid-level trough will impinge on the central Rockies
tomorrow (Thursday), resulting the development of another surface
low over the central Plains. Both gradient and downslope flow will
promote dry and windy conditions supportive of wildfire spread
across portions of the central and southern High Plains. By
afternoon peak heating, widespread 15-20 mph sustained southwesterly
surface winds will overlap with 15 percent RH for several hours,
warranting Elevated highlights across the central and southern High
Plains. Critical highlights have been introduced where guidance
consensus depicts the highest likelihood of 20+ mph sustained winds
overlapping very dry fuels.

U.S. Day 3-8 Fire Weather Outlook

Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0502 PM CDT Tue Mar 31 2026
Valid 021200Z - 081200Z
...Synopsis...
Amplified upper-level flow will progress from the western U.S. into
the Great Plains initiating a lee-surface low in eastern CO/western
KS on D3/Thursday. The negatively tilted shortwave trough will
traverse the northern High Plains on D4/Friday and shift northeast,
bringing cooler temperatures, much needed rain, and higher elevation
snow to much of the western U.S., with precipitation expanding
eastward east of the Continental Divide through the remainder of the
week. This should reduce broader fire weather concerns across parts
of the High Plains into the Midwest. However, fire weather concerns
will remain for areas that do not see appreciable rainfall on Day
3/Thursday and Day 4/Friday in the central and southern High Plains.
An upper ridge builds back across the western U.S. thereafter,
bringing warm and dry weather through the end of the forecast
period.
...Day 3-4/Thursday-Friday - Southern High Plains and far West
Texas...
Strong westerly mid-level winds and lee surface troughing will
continue to support dry, downslope favored flow across the southern
High Plains for both D3/Thursday and D4/Friday. With the
intensification of a surface low and deepening upper trough, a tight
surface pressure gradient will develop in southeastern CO and
northeastern NM on Day 3/Thursday. 70% Critical fire weather
probabilities have been introduced for this region to account for
south-southwesterly winds of 20-30 mph and RH of 10-20 percent atop
receptive fuels. For Day 4/Friday, 40% probabilities of Critical
have been maintained across the southern High Plains, though will
likely need to be adjusted as confidence increases in the location
and timing of a cold frontal passage in the TX Panhandle. Model
guidance is hinting at a potential downslope wind event in the
northern CO Front Range on Day 4/Friday, but have withheld from
introducing highlights until there is better ensemble member
agreement.
Upper ridging builds back in this weekend across the western U.S.,
persisting through early next week. Given the overall pattern,
locally elevated fire weather conditions may arise as dry conditions
prevail across parts of the central and southern High Plains.
