Upper ridging will build over the West, with temperatures rising to above normal west of the Continental Divide. Relative humidity will fall to 5-15% across portions of California and the Great Basin but winds will be light. A cold front will move through the Great Lakes and Mid-Mississippi Valley into the Lower Mississippi Valley and southern Plains. Hot, dry, and breezy conditions are expected ahead of the front across the southern Plains as south-southwest winds 10-20 mph with gusts 20-30 mph develop amid relative humidity of 15-25%. Very dry conditions will continue over much of the Southeast as well, as relative humidity falls below 30%, with locally elevated conditions possible across portions of Virginia and North Carolina due to west winds of 10-15 mph. Scattered showers and thunderstorms are likely near the front from the Great Lakes through the Ohio Valley into the Lower Mississippi Valley, but amounts are expected to be light. Scattered wet thunderstorms are likely over south Florida, while isolated wet thunderstorms remain possible over far southern Arizona and New Mexico.
