A cold front pushed east into Wisconsin during the afternoon and evening hours of April 10th. Severe thunderstorms developed along the cold front and produced large hail and damaging winds over portions of southeast Minnesota. Trained spotters and law enforcement reported hail up to three inches in diameter along with barns, trees and power lines blown down in the counties of Fillmore and Houston. In Houston County, two swaths of straight-line wind damage occurred.  The damage paths were just north of Caledonia, crossing State Highways 76 and 44.  Radar estimates on wind speed were upward of 70 mph. An estimated fifty to sixty trees and a wind mill were knocked downed.
