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 >

The prolonged stretch of heat will continue through the weekend with highs in the mid-to-upper 90s and heat indices of 100-105+ degrees. Overnight lows will only fall into the mid-to-upper 70s, which will not provide much relief from the heat. As such, an Extreme Heat Warning has been issued for all of northern MO through Saturday evening and for central MO through Tuesday evening.
