Severe thunderstorms developed in the vicinity of a front that was stalled across northeast Wisconsin.  Bowing lines of thunderstorms and supercell thunderstorms produced considerable wind damage, some hail, street flooding and a brief tornado touchdown.  Strong winds downed numerous trees and power lines.  Some homes were damaged when trees fell on them.  About 25,000 customers lost electrical power due to the storms.  A tornado touched down briefly at Lake Tomahawk (Oneida co.) resulting in tree damage.  Heavy rainfall caused street flooding at several locations.
