Severe Storms and Tornadoes Threaten Midwest and South.

A dangerous storm system is expected to hit the Upper Midwest and South, bringing with it fast-moving storms that could produce damaging winds, tornadoes, and large hail. Widespread and damaging thunderstorms are likely, and flash flooding is also possible. The storms could affect an area stretching from Louisiana to Wisconsin, including Little Rock, Ark., Memphis, St. Louis, Des Moines, Chicago, and other major cities. Crews worked to clear debris from drains in areas prone to flooding, and officials encouraged residents to have a plan to take shelter, prepare for possible power outages, and have multiple ways to get weather alerts.
