Day 1 Fire Weather Outlook  
NWS Storm Prediction Center Norman OK
0102 AM CST Fri Dec 02 2022

Valid 021200Z - 031200Z


Critical fire weather conditions are expected today across portions
of the central High Plains. Early-morning surface observations show
robust troughing in the lee of the central to northern Rockies ahead
of a progressive upper-level wave. A surface cyclone consolidating
across the northern High Plains will shift east through the day with
a trailing cold front surging south/southeast in its wake. Strong
winds ahead of and behind this front will support fire weather
concerns across eastern CO and much of western KS.

...Central High Plains...
Strong downslope flow is already evident in the lee of the CO
Rockies where RH is falling into the 20-30% range. This dry air mass
will spread east into eastern CO and western KS by early afternoon
behind the surface trough. Continued downslope warming, coupled with
clearing skies, will allow temperatures to warm into the low 70s
with RH values falling into the 15-25% range. Sustained gradient
winds at 20-25 mph will see frequent gusts to 30-40 mph amid deep
boundary-layer mixing. The greatest fire weather concern will likely
emerge across portions of west-central KS where critical wind/RH
will overlap with the greatest 14 and 30-day rainfall deficits.

The cold front will most likely move into northwest KS by late
afternoon, bringing a shift to northwesterly winds gusting to 40-50
mph. While RH is expected to quickly recover behind the front, the
strong post-frontal winds may support spread of any ongoing fires.
