Tornadoes that tore through parts of the South and Midwest killed at least 11 people, collapsed the roof of a packed theater during a heavy metal concert in Illinois, and left small towns and big cities throughout the region bewildered Saturday by the damage.
Possibly dozens of tornadoes touched down into the night across at least seven states, laying waste to homes and businesses and splintering trees, as part of a sprawling storm system that also brought wildfires to the southern Plains and blizzard conditions to the Upper Midwest.
