318 FNUS28 KWNS 082151 FWDD38 Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0449 PM CDT Tue Jul 08 2025 Valid 101200Z - 161200Z ...Day 3/Thursday... A mid-level short wave with associated stronger deep layer westerly flow will bring a fire weather threat to a corridor from the Arizona Strip to the Western Slope. The stronger westerly flow in concert with a dry/well-mixed boundary layer will promote a dry and breezy setup amid an increasingly dry fuelscape. ...Days 4-8/Friday-Tuesday... Model guidance consensus indicates a broad mid-level ridge centroid slowly propagating westward from AZ on Day 3/Thursday to off the southern CA coast by Day 7/Monday. Primary impact will be increasing temperatures to above seasonal normals along with dry conditions across the majority of the West, aiding in drying of fuels. Stronger west-northwesterly flow across the Northern Tier states could provide for elevated surface winds at times, but overlap of a low relative humidity/dry fuel environment is not likely with the exception of southern ID/Snake River Plain over the weekend (Days 5-6/Saturday-Sunday). Overall thunderstorm threat will be limited to the eastern U.S. (along and east of the Continental Divide) through early next week. ..Williams.. 07/08/2025 ...Please see www.spc.noaa.gov/fire for graphic product... $$
