A mid-level trough will traverse the Midwest/Great Lakes Regions as upper ridging remains in place over the Interior West, but with a small but pronounced mid-level impulse impinging on the northern California coastline today. This impulse, in tandem with adequate instability, will provide enough lift to support at least scattered thunderstorms to portions of the Pacific Northwest this afternoon into the overnight hours. These storms will move atop a modestly dry boundary layer, with wet and dry storm modes both possible. Nonetheless, these storms will overspread dry fuel beds, especially from the central/northern Cascades and points east. Dry thunderstorm highlights remain in place for the possibility of lightning strikes (some dry) posing a hazard for fuel ignition. ..Squitieri.. 09/05/2025 ...Please see www.spc.noaa.gov/fire for graphic product... $$
