Hot, dry, and unstable conditions will continue across the Northwest extending into northern California, the northern Rockies, and northern Great Basin. Temperatures up to 110°F will occur in the lower valleys, with widespread temperatures in the 90s in the higher elevations. Relative humidity will fall to 10-25% with poor overnight recovery below 30% for many mid-slopes and ridges. In addition, gusty westerly winds will develop in the Cascade Gaps, while isolated to scattered mixed wet and dry thunderstorms develop over northern California into southwest and central Oregon with several new ignitions likely. Monsoon moisture will remain across the southern Sierra and Southwest into the greater Four Corners, with scattered wet thunderstorms in the afternoon and evening. Cooler temperatures are forecast across much of Texas into the Lower Mississippi Valley, but dry and gusty post-frontal northerly winds will create locally elevated conditions in north and central Texas into Louisiana. Scattered thunderstorms will develop near the stalled front in south Texas and along the Gulf Coast with potential new ignitions, while scattered to widespread thunderstorms will develop along the East Coast. Cooler, moisture conditions are forecast for Interior Alaska.
