A much drier airmass will move into northern California, Inland Northwest, northwest Great Basin, and Northern Rockies west of the Divide, with afternoon relative humidity of 5-20% and poor recovery of 20-40% for mid-slopes and ridges. Portions of southeast Oregon into southwest Idaho may have dry and breezy conditions as well. Isolated to scattered mixed wet and dry thunderstorms are likely to be ongoing across portions of central and eastern Idaho into southwest and central Montana in the morning, with scattered to widespread showers in eastern Montana throughout the day. Isolated mixed wet and dry thunderstorms are possible across portions of northern California, southern Oregon, and northwest Nevada. Scattered monsoonal thunderstorms will develop across much of the Southwest, eastern Nevada, southeast Idaho, Utah, Colorado, and Wyoming. Hot, dry, unstable, and breezy conditions are likely across north Texas into the central Plains, with the most critical conditions across north Texas into southwest Oklahoma. A brief surge of Gulf of Mexico moisture is expected for central and south Texas, with minimum relative humidity near or above 30%, but increased stability will limit chances for thunderstorms except near the Gulf Coast. Showers and thunderstorms are expected across the portions of the northern Plains into the western Great Lakes ahead of a cold front while scattered showers and thunderstorms develop along the Gulf Coast.
