Severe Weather and Heavy Rainfall from the Midwest to the Ohio Valley; Mid-Summer Heat Continues

Severe thunderstorm and heavy rainfall threats will persist from the Midwest to Lower Great Lakes through Monday, shifting into the Ohio Valley and Central Appalachians Monday evening into Tuesday.

Multiple rounds of thunderstorm potential are in place today and tomorrow. Confidence in storm formation is lower today than it is expected to be tomorrow. The primary threats from severe thunderstorms, if they can survive, will be gusty winds (+50mph) and hail up to 1”. Additionally, stronger storms can produce frequent lightning and localized downpours that can create dangerous conditions for outdoor activities. Make sure to stay weather aware!
Temperatures will stay warm through the first half of the week. A busy upper-level pattern will support chances for afternoon thunderstorms for the next few days. Model data has struggled to pinpoint where and when these may form, thanks to the detrimental warm air that has sat over the area. Regardless, stay weather aware during outdoor activities!
