Expansion was given to the Elevated across the Front Range in
Colorado and into northern Kansas with this outlook in alignment
with recent trends in hi-res data. Within the broader Elevated,
locally Critical conditions will be possible, primarily in the
foothills outside of the Denver metro. See previous discussion below
for more information.

...Synopsis...
Weak surface lee troughing beneath zonal flow aloft will support
relatively quiescent fire weather conditions for most of the central
CONUS today. The one exception will be over portions of the central
High Plains, where locally stronger downslope flow is expected as a
small mid-level impulse overspreads the region during the afternoon.
15-20 mph sustained westerly surface winds amid 20-25 percent RH
will overlap with drying fuels for several hours, warranting the
continuance of Elevated highlights.

...Synopsis...
A mid-level trough will eject into the southern Plains tomorrow
(Wednesday), supporting surface low development over the southern
High Plains. While moisture return is anticipated over the southern
Plains, some dry downslope flow is expected across portions of
western Texas, as well as the central High Plains. In these
aforementioned areas, sustained westerly winds may briefly exceed 15
mph. However, guidance varies in terms of how low RH will dip by
afternoon peak heating, with some guidance showing RH reaching 20
percent in some spots, with other members showing RH only dipping
into the 25-30 percent range on a widespread basis. Given dry fuels,
locally Elevated conditions are possible, but do not seem widespread
enough to warrant highlights at this time.

Day 3-8 Fire Weather Outlook

0342 PM CST Tue Jan 06 2026
Valid 081200Z - 141200Z
A longwave trough will begin to progress out of the western US on
D3/Thursday, with a surface low developing across the Oklahoma/Texas
Panhandles into western Kansas. As this occurs, southerly flow will
increase with moisture advection into the western portion of the
Southern Plains and into the Mississippi and Missouri River Valleys.
Widespread rain/thunderstorm activity can be expected across some
portions of the central/eastern Southern Plains into the
Mississippi/Missouri River Valley. Less precipitation is likely
across portions of western Texas into western Oklahoma, where fire
concerns are possible D4/Friday and 5/Saturday.
...(D4/Friday - D5/Saturday) Southwestern/West-Central Texas...
Model guidance has been consistent in forecasting a steep gradient
in precipitation amounts extending from central
Oklahoma/north-central Texas, with the heaviest amounts eastward.
Confidence is increasing that portions of western Texas into western
Oklahoma will receive little to no precipitation. Latest fuels
guidance suggests grass loading is high with freeze cured grasses
present and ERCs around the 80th percentile. Strong and dry post
frontal northwesterly flow will overspread the Plains behind the
departing low. Overlap of relative humidity reductions to 15-20
percent are expected to overlap sustained northwesterly flow around
20 mph. A 40 percent area was included at this time given some
uncertainty still in where the gradient of higher precipitation will
be. Should precipitation totals exceed or not meet expectation,
some reduction or expansion of this area may be needed in upcoming
outlooks.
Lingering Elevated to Critical conditions may be possible again
across portions of southwestern Texas into far southwestern Oklahoma
on D5/Saturday. For now confidence is too low to include any areas
at this time.
