Heavy Rain and Flash Flooding in the West; Heat Expands in the Central U.S.

Monsoonal moisture will produce showers and thunderstorms with heavy rain over parts of the Southwest, Great Basin, and Central Rockies through Monday. Flash flooding is possible, especially in and around burn scars and in areas of steep terrain. Heat will persist across the Central U.S. early this week, spreading into the Ohio Valley and Mid-Atlantic later this week. Read More >

Isolated to widely scattered thunderstorms may occur tonight. An isolated strong storm or two could not be ruled out, but otherwise, lightning and downpours are expected to be the main hazards with any storms. After one more humid day on Saturday, humidity levels will come down for Sunday and Labor Day. Temperatures won’t be as hot as they were earlier this week either, but they will still be seasonably warm.
