FNUS28 KWNS 202041 FWDD38 Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0339 PM CDT Fri Mar 20 2026 Valid 221200Z - 281200Z Upper ridging is poised to overspread the CONUS through the extended (Days 3-8) period. Embedded mid-level impulses will traverse the upper ridge, encouraging a surface cold front to sweep across the CONUS (east of the Rockies) early in the week. Thereafter, surface lee troughing will become established across the Plains, promoting occasional bouts of dry downslope flow across portions of the High Plains. ...Day 3/Sunday... A surface low will encourage dry downslope flow across the southern High Plains as an approaching cold front sweeps southward across the central and southern Plains on Sunday. The best chance for critically dry and windy conditions will be across portions of the Texas Rolling Plains per latest guidance consensus. However, at least Elevated-equivalent dry/windy conditions are expected across the remainder of the southern High Plains due to dry downslope flow, and across northern Oklahoma into Kansas behind the cold front. While temperatures (and thus RH) will be lower in Oklahoma/Kansas compared to points farther south, very strong northerly surface winds, potentially exceeding 30 mph in spots, will encourage rapid wildfire-spread potential given dry fuels. ...Day 4/Monday... The surface cold front will sweep across the East Coast while surface lee troughing continues across the High Plains on Monday. 40 percent Critical probabilities remain in place across southern Virginia into northern South Carolina, where guidance consensus continues to show a dry and breezy post-cold-frontal environment over dry fuels. Dry downslope flow will also promote dry and windy conditions across southern Wyoming, warranting the continuation of 40 percent Critical probabilities here as well. ...Day 6/Wednesday... The next chance for appreciable wildfire-spread potential will be on Wednesday across portions of Wyoming and immediate surrounding areas. A mid-level impulse will traverse the region, enhancing downslope flow and supporting dry/windy conditions for several hours Wednesday afternoon. 70 percent Critical probabilities were introduced given multiple preceding days of no rainfall and dry/windy conditions, which will further cure fuels that are already receptive to fire spread. ..Squitieri.. 03/20/2026 ...Please see www.spc.noaa.gov/fire for graphic product... $$
