More than 35 million people will be at risk for severe thunderstorms on Tuesday and Tuesday night from the Plains to the Midwest.
A few of the major cities that could have damaging winds and large hail include Chicago, Ill., Madison, Wis., Milwaukee, Wis., Omaha, Neb., Minneapolis, Minn. and Cedar Rapids, Iowa.
The timing of these storms may cause headaches for commuters as they could move through heavily populated cities, like Chicago, during rush hour. This would lead to major traffic delays as well as an increased number of accidents due to the blinding downpours that these storms produce.
To add to the traffic delays, powerful wind gusts that blow trees across roadways will force traffic to be diverted while emergency crews clear the debris.
