What happened

The episode as NWS GRB wrote it up.

Strong thunderstorms developed ahead of an area of low pressure riding along a cold front. Additional support was provided by the passage of an upper level disturbance. Mainly pea-size hail was reported with this event. However, as the storms approached Green Bay, the strong winds aloft became surface-based. An estimated wind gust to 60 mph was reported 3 miles SW of De Pere. Damage included: several trees and out buildings knocked down, a barn damaged, and a billboard on Hwy 41 was knocked down.
