Wisconsin Tornado Extreme Weather

A tornado has swept through Wisconsin, damaging homes, downing trees and knocking out power to thousands of people. The National Weather Service confirmed a tornado in Winnebago County, about 90 miles northwest of Milwaukee. Officials say the twister moved over Lake Winnebago and moved southward toward Fond du Lac County around 12:25 p.m. Images posted to social media showed extensive damage in Appleton, including homes stripped of roofs and siding, cars flipped over and streets littered with tree limbs. In Menasha, the electric utility said the entire city of about 18,000 people is believed to be without power because of a downed transmission line.
