More bad weather could hit Iowa, where 3 powerful tornadoes caused millions in damage
A deadly tornado that wreaked havoc in the small city of Greenfield, Iowa, left four people dead and nearly three dozen injured, officials said, while a fifth person was killed elsewhere. The twister that tore through the city on Tuesday was rated at least an EF-3 by the National Weather Service and was so destructive that it took authorities more than a day to account for the area's residents.
