Well above normal temperatures are expected across much of the Northwest, northern Rockies, and portions of northern California and northern Great Basin, but a weakening upper-level ridge, cloud cover, and smoke will likely decrease temperatures slightly from recent days, except along and east of the Divide in Montana. Gusty west-southwest winds amid relative humidity of 8-25% will result in elevated to critical fire weather conditions along and east of the Divide in Montana, across northern Wyoming into the western Dakotas, and in central and eastern Washington. Overnight humidity recovery will improve across northern California, the Pacific Northwest, northern Great Basin, and into the northern Rockies due to increasing moisture. Isolated to scattered mixed wet and dry thunderstorms are expected across much of northern California, Oregon, and into the northern Great Basin, central Washington, southwest Montana, and western Wyoming. Greater coverage of thunderstorms is likely in southern Oregon and far northern California, where chances of isolated wetting rain are higher. Scattered to widespread mostly wet thunderstorms are expected in the eastern Sierra, south of Lake Tahoe, across central Nevada into portions of eastern and northern Nevada, and in the greater Four Corners region, especially southern Colorado into northern New Mexico. Well above normal temperatures are forecast for the Plains, with hot, dry, and unstable conditions in portions of west, central, and north Texas into southwest Oklahoma. Dry and windy conditions are expected on leeward sides of the Hawai’ian Islands. Strong to severe thunderstorms are possible from the Missouri Valley through the Ohio Valley, with heavy rain and flooding likely again in portions of the southern and central Appalachians. .
