Overview

Intense severe thunderstorms produced large hail, severe winds, and two tornadoes across central Minnesota and west-central Wisconsin during the daytime hours on Friday. Discrete supercells began in west-central Minnesota and traveled eastward before eventually growing upscale into a bowing mesoscale convective system. A highly anomalous summertime environment containing both extreme thermodynamic instability and strong vertical wind shear allowed for explosive, long-lived thunderstorms. Baseball to three-inch size hail was reported across central and east-central Minnesota while wind gusts in excess of 80 mph were reported across west-central Wisconsin. Cushing, WI had a notable wind gust of 84 mph.
