A hot, dry, and unstable air mass will continue to build across the West. Daytime RH will drop to 3-15% with poor overnight recovery across much of California, the Northwest, Great Basin, northern Rockies, West Slope, and central High Plains. Temperatures are forecast to exceed 100°F in lower elevations of these regions and peaking near 110°F in inland California, the southern Great Basin, and western Arizona. Locally breezy west winds of 12-20 mph (gusts to 35 mph) are expected in the Cascade gaps, northern Sierra Front, northern Great Basin, and northern Rockies. Monsoon moisture remains limited in the Southwest. Isolated to scattered wet thunderstorms will favor the Mogollon Rim, southeast Arizona, and southwest New Mexico, while isolated dry thunderstorms are possible in southeast California, the southern Great Basin, and the southern Sierra. In the East, showers and thunderstorms will briefly diminish in Florida but will continue along the Gulf Coast into the Lower Mississippi Valley. Temperatures will remain near normal east of the Mississippi River, except in parts of New Hampshire, Vermont and Maine, where persistent dry coastal conditions will keep temperatures about 15°F above normal. It will be quite warm and dry over Alaska’s eastern Interior, particularly near the Al-Can border, with increasing potential for new ignitions from isolated lightning. Hot, dry, and breezy conditions will result in moderate potential across Puerto Rico and the U.S. Virgin Islands.
