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 >

A few severe thunderstorms are possible on Saturday as a hot and humid air mass will remain in place this weekend, creating an unstable atmosphere capable of supporting these storms. Main threats will be large hail from quarter to perhaps golf ball size, along with strong wind gusts from 60 to perhaps 70 mph.
With hot and humid conditions remaining in place on Sunday, the atmosphere will be supportive of strong to severe thunderstorm potential across the region. A Marginal Risk for severe storms exists on Sunday across portions of the region.
