An amplified large-scale ridge will continue over the western CONUS on Day 2/Saturday. ...Dry Thunderstorms... Along the western periphery of the ridge, monsoonal moisture will continue spreading northward from the Sierra into the Northwest. Sufficient buoyancy will support isolated mostly dry thunderstorms during the afternoon/early evening time frame. Given dry/receptive fuels, isolated lightning-induced ignitions will be possible. Farther south, isolated thunderstorms are also expected across parts of southern CA into the Great Basin. However, deep monsoonal moisture will promote mixed wet/dry thunderstorms. Nevertheless, lightning-induced ignitions will be possible away from any heavier rain cores, along with gusty/erratic outflow winds. ..Weinman.. 08/22/2025 ...Please see www.spc.noaa.gov/fire for graphic product... $$
