Along the northwestern periphery of an amplified large-scale ridge extending from the Southwest to the Pacific Northwest, monsoonal moisture will continue spreading northward from the Great Basin into northern CA and OR. This will contribute to sufficient buoyancy for diurnally driven thunderstorms during the afternoon into the evening -- likely aided by a convectively augmented/generated midlevel vorticity maximum/MCV emerging from the northern Sierra. A mix of wet/dry thunderstorms are expected, and given receptive fuels across the region, lightning-induced ignitions will be possible away from any heavier precipitation cores that evolve. ..Weinman.. 08/23/2025 ...Please see www.spc.noaa.gov/fire for graphic product... $$
