Day 1 Fire Weather Outlook  

NWS Storm Prediction Center Norman OK

0157 AM CDT Mon Aug 24 2026



Valid 241200Z - 251200Z



...Synopsis...

A subtle/low-amplitude midlevel wave will move northeastward across

parts of the northern Great Basin today. Farther south, a separate

shortwave trough will track southeastward across the

central/southern Plains -- along the northeastern periphery of an

expansive upper ridge centered on the southern Rockies. In response

to this feature, a surface low will evolve slowly eastward across

parts of OK.



...Dry Thunderstorms - Northern Great Basin...

Diurnal heating/boundary-layer mixing beneath a well-established

midlevel moisture plume will contribute to weak surface-based

destabilization across parts of the northern Great Basin today. As

large-scale forcing for ascent accompanying the midlevel wave

overspreads this instability, isolated high-based thunderstorms will

track northeastward across the area. The deeply mixed boundary layer

(inverted-V profiles) and 25-30 mph storm motions will favor dry

thunderstorms capable of lightning-induced ignitions -- given

receptive fuels. 



...Southern Plains...

Along/behind the evolving surface low, a dry air mass (15-20 percent

RH) will develop amid 15-20 mph sustained west-southwesterly surface

winds. These dry/breezy conditions atop increasingly dry fuels

(95th+ percentile ERCs) will yield elevated fire-weather conditions

during the late morning and afternoon.
