500 FNUS56 KSEW 302243 FWFSEW Fire Weather Planning Forecast for Western Washington National Weather Service Seattle WA 343 PM PDT Sat Aug 30 2025 .DISCUSSION...A slight chance of dry thunderstorms is forecast for the North Cascades tomorrow (10-15%) as low pressure remains offshore. Steep lapse rates offer plenty of downdraft potential, but there is insufficient moisture and weak lift, leading to dry lightning strike concerns. Later in the week, temperatures warm up and dry out with hot, dry and unstable conditions by late week. Forecast for 20 foot wind speed (valleys and ridge tops) are 10 minute averages reflecting RAWS winds.
