799 FNUS56 KSEW 051458 FWFSEW Fire Weather Planning Forecast for Western Washington National Weather Service Seattle WA 758 AM PDT Fri Sep 5 2025 .DISCUSSION...Onshore flow looks to bring a modest improvement throughout the area today, with even better RH recoveries into the weekend. Over the weekend, an upper level trough and low pressure system will move into the region to boost the chances for widespread thunderstorms and showers, but confidence in the specific timing and coverage still remains low. Isolated thunderstorms could possibly start as early as this afternoon for the southern Washington Cascades, but again, coverage seems very limited at this time. Forecast for 20 foot wind speed (valleys and ridge tops) are 10 minute averages reflecting RAWS winds.
