Brief Description: A tornado touched down just northwest of Lewiston (Winona County), then moved into the middle of town and intensified. Numerous homes along Main Street had extensive damage with broken windows, damaged roofs and downed trees. One home had the entire roof taken off, while at least 4 cars were demolished from debris landing on them. A farm southeast of town had every building destroyed, except the house. Of the 1,300 population in Lewiston, only two people sustained minor injuries. Elsewhere across southeast Minnesota, spotters and law enforcement officials reported hail up to 2 inches in diameter along with trees and power lines knocked down. | |||||||||||
