The upper-level ridge will shift east due to an upper low moving into Oregon. Temperatures will continue to run well above normal for much of the western US, especially in the Pacific Northwest where more record daily temperatures are possible. The heat will also spread more into the High Plains. High temperatures over 105°F are expected from southern Arizona through the California Central Valley, with highs approaching 100°F in the Inland Northwest. Low relative humidity of 4-20% will continue as well, with poor overnight recovery of 10-30% for mid-slopes and ridges across the Intermountain West. Isolated dry thunderstorms will continue across central and eastern Oregon into Nevada, with breezy afternoon southwesterly winds gusting to 30 mph across southeast Oregon, the eastern Sierra Front, and the western Great Basin. Limited moisture will remain in eastern Arizona and east towards the Divide. Isolated mixed wet/dry thunderstorms are still possible along the Mogollon Rim and into much of New Mexico and southwest Colorado. Farther east, a cold front will continue to move across Appalachia and the Northeast, but little rainfall is forecast outside the Northeast. Most of the thunderstorm activity along the Gulf Coast will remain off the coast, with a chance for rain across the Florida Peninsula. North to northwesterly winds from the southern Plains and into the Tennessee and Ohio Valleys will be gusting 15 to 25 mph behind the cold front.
