245 FNUS28 KWNS 231932 FWDD38 Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0230 PM CDT Sat Aug 23 2025 Valid 251200Z - 311200Z Upper ridging will prevail across the western and central CONUS through much of the upcoming week, before a mid-level trough attempts to impinge on the West Coast by next weekend. Through much of the period, deep-layer mid-level moisture will continue to progress northwestward across the northern Great Basin and eventually toward the Pacific Northwest. The chances of isolated to scattered thunderstorms will increase across these regions through early next week. However, there are uncertainties pertaining to the efficiency of lightning-based ignitions given the degree of available moisture (i.e. potentially greater than 1 inch precipitable water values) and appreciable rainfall accumulations from thunderstorms in the Days 1-2 time frame. Isolated dry thunderstorm probabilities have been withheld, though dry thunderstorm highlights cannot be completely ruled out by early next week. ..Squitieri.. 08/23/2025 ...Please see www.spc.noaa.gov/fire for graphic product... $$
