The National Weather Service is confirming Monday's thunderstorms spawned six confirmed tornadoes in the state. Weather service teams surveyed damage in southern and eastern Iowa and determined Muscatine saw an EF-2 tornado with winds peaking over 115-miles-an-hour and carving a path nearly two-miles long. Centerville also measured an EF-2, while people in Knoxville are cleaning up after an EF-1 tornado. EF-0 tornadoes rumbled through the Harcourt and Dayton areas. Damage estimates are still being figured.
