Folks from parts of Missouri to the Ohio Valley states and Virginia will be in a zone for potentially strong thunderstorms into Wednesday evening.
A humid air mass and heating from the day will provide the fuel for scattered showers and thunderstorms to form. Cool air aloft will will allow some of the storms to become strong to briefly severe.
Cities at risk for adverse weather and disruptions to travel and outdoor activities include St. Louis; Indianapolis; Cincinnati and Columbus, Ohio; Louisville, Kentucky; Charleston, West Virginia; and Richmond, Virginia.
The biggest threats with these storms will be gusty winds and hail. Due to the slow nature of these storms, some areas may experience flash flooding as heavy downpours focus on a particular area longer.
Motorists caught out in a heavy downpour will experience poor driving conditions and may need to slow down or pull over until the heavy rain passes.
Remember never to drive through a flooded roadway. The water may be much deeper than it appears and the road could be washed out beneath. To do so will not only put you and passengers at risk but also your would be rescuers. Turn around and find an alternate route if you encounter flooding.
Major highways that may face delays include I-64, I-65, I-70, I-71 and I-75.
Although the weather pattern doesn't favor a widespread severe outbreak, some of these storms could pack a punch.
