002 FNUS22 KWNS 211854 FWDDY2 Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0153 PM CDT Mon Sep 21 2026 Valid 221200Z - 231200Z ...NO CRITICAL AREAS... Ahead of an approaching upper trough currently in the eastern Pacific, stronger southwest winds will overspread the Pacific Northwest on Day 2/Tuesday. As a cold front passes through the Columbia Basin on Tuesday morning/afternoon, high temperatures will be about 5-10 degrees cooler amid 25-35% RH values. Given the favorable orientation of stronger upper-level winds, wind gusts of up to 35 mph are possible in terrain-favored areas; however, a marginal fuelscape limits a broader fire weather threat. The rest of the forecast remains on track, please see the previous discussion for more information. ..Elizalde-Garcia.. 09/21/2026 .PREV DISCUSSION... /ISSUED 0158 AM CDT Mon Sep 21 2026/ ...Synopsis...

Elsewhere, a cold front will continue to stretch across the far southern Plains bringing shower and thunderstorm activity across portions of western and south-central Texas. Mid-level heights will begin to rise again across the central US with warming temperatures but generally light winds. ...Please see www.spc.noaa.gov/fire for graphic product... $$
