A Thursday Morning Update for Today’s Showers and Storms

Posted: 9:17 AM EDT 08/22

We will see two rounds of showers and thunderstorms today. The first is a line moving in from the southwest this morning. The Valley should start to see rain moving in from this first system by 11:00 AM or so.

This first round is from a decaying storm system. By the time it arrives here in the Valley, there should not be much left in the way of thunderstorms. Most neighborhoods will end up with light rain but a few pockets of moderate rainfall might still hold together, though.

The main concern for stronger thunderstorms then shifts to later this afternoon. A cold front over Lake Erie this morning will sink southward later today. This will spark off another round of showers and thunderstorms.

While this morning’s activity and cloud cover are likely to limit the potential for severe weather later today, there still is a low-end threat for a strong gusty thunderstorm.

The highest concern with this afternoon’s thunderstorms is the potential for training storms and heavy rainfall. Areas that see repeating cells of heavy rain will have an increased risk for flash flooding through this evening.

This morning’s high-resolution computer guidance brings the risk for heavier thunderstorms into the Valley from 2:00 PM through around 6:00 PM.

Showers and thunderstorms will continue this evening as the front makes its way south. The cold front should exit east-central Ohio late tonight and this will bring an end to showers and thunderstorms.
