 Storms spawning multiple tornadoes blew through Iowa, Illinois, including Chicago and Indiana Monday, downing trees and power poles and cutting power to more than 460,000 customers and businesses. The National Weather Service confirmed a tornado hit Des Moines, Iowa, and storms rolled through Monday afternoon into the night. Des Moines police were responding to calls about utility poles that apparently snapped in half. The storms then moved east into northern Illinois, including the Chicago area, which saw multiple tornado warnings, wind and drenching rain.
