From the Associated Press:
Swarms of tornadoes killed at least 10 people across the Midwest, shut down the University of Kansas and caused so much damage in Springfield that the mayor compared it to the aftermath of Hurricane Katrina.
The violent weather started during the weekend with a line of storms that spawned tornadoes and downpours from the southern Plains to the Ohio Valley.
On Monday, a second line of storms raked the region, with rain, hail and fierce wind tearing up trees and homes from Kansas through Indiana. To the northwest, the vast weather system pulled cold air in Canada, generating snowstorms that cut off power to thousands and shut down schools in South Dakota, Minnesota and Wisconsin.
Illinois' capital was hit hard twice in 24 hours, first by a tornado and then strong wind early Monday that blew debris through the city. Power lines were down across Springfield, trees uprooted and windows blown out.
