Elevated to critical fire weather conditions are expected from northeast California and the Sierra Front through central Idaho into western, northern, and eastern Montana and the western Dakotas. West-southwest sustained winds of 15-20 mph gusting 25-40 mph amid minimum relative humidity of 5-20% are likely from northeast California into western Montana, and southeast sustained winds of 15-20 mph gusting 25-35 mph are likely across eastern Montana into the western Dakotas amid minimum relative humidity of 8-25%. Higher humidity will move into portions of the Pacific Northwest, including better overnight recovery in portions of the Inland Northwest, northern Rockies, and northern Great Basin. Isolated to scattered high-based thunderstorms and showers are likely across portions of central and eastern Washington and northern and eastern Oregon into northern Idaho and northwest Montana. Isolated to scattered thunderstorms are likely across the higher terrain of the Southwest, southern California, and Colorado Rockies, including some severe to strong thunderstorms. Scattered to widespread thunderstorms are likely across much of Texas and the Southeast, and isolated to scattered thunderstorms are possible from Oklahoma through the Ohio Valley into the Appalachians and eastern Great Lakes ahead of a cold front.
