Overview

Damaging winds and small hail resulted from a cluster of thunderstorms that organized into a line and tracked through central and southeast Wisconsin early Sunday evening. The storms formed along the leading edge of an upper level disturbance. They ended up being stronger than expected because there were large breaks in the clouds during the afternoon. This helped to warm the temperatures and allow for greater instability. 

Wind gusts up to 60 mph knocked down branches, trees and power lines across portions of east central and southeast Wisconsin between 4 and 7 pm. There were a few reports of small hail as well.
