[11:44 AM] Most of the area woke up on Monday with a fresh coating of snow on the ground. By Tuesday morning, rumbles of thunder likely woke some up as multiple rounds of heavy rain/thunderstorms created widespread flooding throughout parts of the area. By the afternoon, severe storms developed producing large hail, damaging winds, and even a few tornadoes. Last night and this morning, strong winds behind a cold front gusted in excess of 40 MPH and now much of the area is experiencing scattered snow showers with reduced visibility. Just another weather stretch in the Ohio Valley!
