Day 1 Fire Weather Outlook  

NWS Storm Prediction Center Norman OK

1250 AM CDT Sat Jul 18 2026



Valid 181200Z - 191200Z



...Synopsis...

Along the northwestern periphery of an expansive upper ridge over

the West, a midlevel trough will advance eastward across BC and the

Northwest during the day. Within the base of the trough, strong

midlevel southwesterly flow will overspread WA, OR, northern CA, and

northwest NV. Associated downslope flow in the lee of the Cascades

and northern Sierra will aid in deep boundary-layer mixing into the

strengthening flow aloft. This will yield a broad area of 15 mph

sustained west-southwesterly surface winds (with higher gusts) amid

10-15 percent RH. Locally stronger surface winds can be expected in

terrain-favored/gap-flow areas through the Cascades. Given

dry/receptive fuels across region, elevated fire-weather conditions

are expected. 



Farther east, lee troughing over the northern High Plains will

promote 10-15 mph sustained easterly surface winds across parts of

southeastern WY during the afternoon. These winds, combined with

15-20 percent RH and dry fuels, will favor elevated fire-weather

conditions.

Day 2 Fire Weather Outlook  

NWS Storm Prediction Center Norman OK

1251 AM CDT Sat Jul 18 2026



Valid 191200Z - 201200Z



...NO CRITICAL AREAS...



...Synopsis...

An upper ridge will build over the Northwest in the wake of a

departing midlevel trough. While a continuation of warm and dry

conditions are expected, weaker surface winds will limit

fire-weather concerns regionally compared to previous days. However,

locally elevated conditions are still possible in wind-prone areas,

given the continuation of warm/dry conditions and receptive fuels.
