In a week that has produced hundreds of reports of severe weather and over 60 reports of tornadoes, the threat for more damaging storms will continue Thursday across the Plains and the Midwest.
The threat of severe storms will extend over a large area from North Texas northward into Wisconsin and Minnesota, including Minneapolis, Des Moines, Omaha, Wichita and Oklahoma City. The greatest threat for tornadoes will extend from northern Missouri southwestward into northeastern Oklahoma, including Kansas City, Springfield, Mo., and Tulsa, Okla.
By Thursday night, strong to severe storms will move eastward, potentially impacting Milwaukee, Chicago and St. Louis.
