Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0111 AM CST Sun Jan 04 2026
Valid 041200Z - 051200Z
...Synopsis...
A broad mid-level ridge will be located across the central United
States on Sunday. To the west of this ridge axis, westerly winds
will develop across the Front Range early in the forecast period
before slowly backing late to west-southwest in the period. This
westerly flow will contribute to warm, dry conditions across much of
eastern Colorado, northeast New Mexico, and the surroundings Plains
of Texas and Oklahoma Panhandles.
Forecast minimum relative humidity percentages across this region
will support fire weather conditions, meaning that it will fall
below the 20-25% range. The biggest question about fire weather
concerns will be the strength of the low-level flow. High-resolution
guidance this evening confines the strongest winds (those in excess
of 15 mph) to the higher terrain of central Colorado and the lower
relative humidity farther east across the Plains.
Given the tendency for guidance to underdo the strength of downslope
winds, have opted to maintain the elevated from central Colorado
into northeast New Mexico and the adjacent Plains of the Oklahoma
and Texas Panhandles for elevated to locally critical fire weather
conditions.

Day 2 Fire Weather Outlook

...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE TEXAS PANHANDLE
AND FAR EAST-CENTRAL NEW MEXICO...
...Synopsis...
The mid-level ridge across the central United States will flatten
during the forecast period as a short-wave trough ejects out of the
Rockies and into the central Plains. As this mid-level wave moves
into the Plains, westerly mid-level flow across the Southern Plains
will correspondingly increase. This will result in another day of
elevated fire weather conditions across much of southeast Colorado,
northeast New Mexico, the Texas and Oklahoma Panhandles, far
southwest Kansas, and western Oklahoma. Here, relative humidity
percentages will fall into the teens to locally high single digits.
The biggest question for critical fire weather conditions will be
the strength of the afternoon surface winds. High-resolution
guidance this evening yields increasing confidence in a belt of
stronger surface winds from far east-central New Mexico into the
southern portions of the Texas Panhandle. Here, afternoon winds will
increase into the 15-20 mph range, with locally higher gusts. These
winds, coupled with minimum relative humidity percentages in the
teens will yield a critical fire weather threat.

U.S. Day 3-8 Fire Weather Outlook

Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0440 PM CST Sat Jan 03 2026
Valid 051200Z - 111200Z
...Synopsis...
By early next week, an upper-level ridge over the central CONUS will
precede a shortwave trough moving into the Four Corners region. West
to southwesterly increasing mid-level flow will impact the Southern
Rockies. This shortwave trough will continue eastward into TN Valley
and Midwest into D4/Tuesday, with quasi-zonal flow anticipated
thereafter. By late into next week, the pattern will become more
amplified as a longwave trough replaces the ridge over most of the
CONUS.
...D3/Monday...
A lee trough will deepen Monday afternoon in response to increasing
orthogonal flow and an approaching mid-level shortwave trough. The
resulting surface pressure gradient, and momentum transfer of
stronger flow aloft, will yield breezy westerly downslope flow from
the High Plains of CO, TX, and NM into the OK and TX Panhandles.
Current uncertainties regarding the duration of critical wind
speeds, especially across the southern TX Panhandle, do not warrant
the introduction of higher probabilities at this time. This overall
pattern, however, does suggest the possibility of more widespread
near critical fire weather conditions given the increasing mid-level
height gradient, orientation of such, and position of the low-level
thermal ridge. The latter should extend southwest to northeast from
the Western Low Rolling Plains into northwest TX/the southeastern TX
Panhandle. Locations just west of this axis within the higher wind
speeds will be investigated in subsequent forecasts for the
potential inclusion of a D2 Critical area.
