Severe thunderstorms and heavy rain are expected across portions of the mid-Mississippi Valley into the Ohio Valley and portions of Arizona.

Overnight lows will be so warm that, when combined with oppressive dew points, little-to-no relief from the scorching daytime highs will be available. Read More >

Last Map Update: Wed, Aug 19, 2026 at 5:38:21 am CDT

Very warm to hot conditions return today with highs in the 90s, and heat index values to 107. A return of moisture and resultant instability from hot conditions, will help lead to shower/thunderstorm development this afternoon primarily over NW Alabama. More thunders are expected tonight and on Thursday and Thursday night. Drier conditions and near seasonable conditions will return Saturday.
