Day 2 Fire Weather Outlook  
NWS Storm Prediction Center Norman OK
1154 PM CDT Mon May 18 2026

Valid 201200Z - 211200Z

...Synopsis...
The active and progressive mid-level synoptic pattern responsible
for recent critical fire weather across the Southwest and southern
High Plains will begin transitioning toward a more quasi-zonal flow
regime on Wednesday. Below-normal temperatures and fairly widespread
precipitation will overspread of the central and eastern CONUS. This
incoming airmass will temporarily dampen the fire weather threat
across a broad portion of the country and support a beneficial
green-up of herbaceous vegetation in some areas, particularly across
the northern CONUS, where fire-slowing vegetation has struggled to
emerge this spring. However, dry and breezy conditions remain in
place for at least one more day across portions of the Southwest.

...Southwest...
Despite the flattening upper-level pattern, a lingering belt of
moderate southwesterly flow aloft (30-40 kts near the top of the
afternoon boundary layer due to strong diurnal heating) will remain
over the Southern Rockies. Sustained southwest winds of 10-20 mph
will align with minimum relative humidity values of 10-20%. Thus, an
area of Elevated fire weather conditions will exist as this wind/RH
overlap coincides with critically dry fuels.
