FNUS28 KWNS 192125 FWDD38 Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0424 PM CDT Tue May 19 2026 Valid 211200Z - 271200Z A shortwave trough and associated mid-level jet streak located over the Intermountain West on Day 3/Thursday will gradually drift across the High Plains and Upper Midwest Day 4/Friday before entering south-central Canada this weekend. Longwave ridging will build across the West on Day 5/Saturday, sliding towards the Central U.S. as extended guidance introduces the potential for a robust upper trough to enter the Pacific Northwest early next week. An Atlantic ridge over the Eastern Seaboard is likely to persist through the forecast period, with multiple rounds of mid-level perturbations promoting repeat opportunities for precipitation. The overall upper pattern suggests dampened fire weather conditions on a broader scale through the forecast period, with the exception of localized breezy conditions across parts of the West. With minimal to no rainfall forecast across the Intermountain West and portions of the Desert Southwest through early next week, and a subsequent warming/drying trend beneath the upper ridge, fire weather concerns may emerge where drying fuels and locally enhanced winds align. ..Elizalde-Garcia.. 05/19/2026 ...Please see www.spc.noaa.gov/fire for graphic product... $$
