047 FNUS28 KWNS 222156 FWDD38 Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0455 PM CDT Thu May 22 2025 Valid 241200Z - 301200Z An upper-level trough will support breezy and dry conditions across portions of the Southwest through Day 4/Sunday, promoting an Elevated to locally Critical fire weather threat with dry fuels in place. An upper-level trough will bring cooler temperatures and some precipitation to the Pacific Northwest and Northern Rockies for the Day 5-6/Monday-Tuesday time frame. An overall ridging pattern sets up over the Western U.S. by the middle of next week supporting above normal temperatures but light winds for much of the region. Residual mid-level moisture under the ridge combined with daytime heating/instability should support convection/isolated thunderstorms in higher terrain across the Central and Northern Rockies Day 6-8/Tuesday-Thursday, although higher terrain fuels should remain largely unavailable for significant fire spread, limiting ignition efficiency. ...Southwest... Primary fire weather concern remains across the Southwest U.S. through at least Day 4/Sunday. An upper-level trough with associated accelerated mid-level southwest flow will bring another period of dry and breezy conditions to portions of the Southwest on Day 3/Saturday. Given the rather diffuse and broad mid-level flow, a 40 percent Critical probability was maintained for portions of the Upper Colorado River Basin, Mogollon Rim and southwestern New Mexico. The fire weather threat shifts farther south and east into southern New Mexico and far West Texas by Day 4/Sunday as the trough ejects into the Great Plains by Day 5/Monday. ..Williams.. 05/22/2025 ...Please see www.spc.noaa.gov/fire for graphic product... $$
