Storms that spawned possibly dozens of tornadoes have killed at least 18 people in the South and Midwest, including at a heavy metal concert in Illinois where the theater's roof collapsed. Possibly dozens of tornadoes touched down into the night in at least seven states. The dead included seven in McNairy County, Tennessee, four in the small town of Wynne, Arkansas, and three in Sullivan, Indiana. Other deaths were reported in Alabama, Illinois, Mississippi and the Little Rock area. Tens of thousands lost power because of the sprawling storm system that also brought wildfires to the southern Plains and blizzard conditions to the Upper Midwest.
