LIVE: Severe outbreak begins to unfold near Chicago

Violent thunderstorms have started to develop in eastern Iowa and northern Illinois and will track eastward through Wednesday night.

"Thunderstorms capable of threatening lives and property will target parts of Iowa, Illinois, southern Wisconsin, Indiana, Ohio, Kentucky, West Virginia and western Pennsylvania on Wednesday and Wednesday night," AccuWeather Senior Meteorologist Kristina Pydynowski said.

As a result, the storms could lead to travel delays, property damage and power outages particularly around Chicago, Indianapolis, Detroit, Cincinnati and Pittsburgh.

People in these areas should take cover as storms approach as they will be capable of producing wind over 70 mph, hail as large as baseballs and damaging tornadoes.
