Severe thunderstorms developed in unstable air in the vicinity of an east to west warm front that stretched across northern Wisconsin.  These storms produced large hail, wind damage and two tornadoes.  Hail to golf ball size covered the ground in the Minocqua area (Oneida co.) and golf ball to tennis ball size hail fell from Arbor Vitae (Vilas co.) to St. Germain (Vilas co.).  The most significant wind damage was in southern Oneida county.  In the Woodboro area (Oneida co.) a tree that was downed by high winds smashed a pickup truck.A tornado touched down in southeast Florence county.  It destroyed a pole barn, a garage that was under construction and 6 to 10 outbuildings in its path.  It caused minor damage to a farm home and downed 150 to 250 trees and power lines, causing numerous power outages.  The tornado tracked east-northeast across the Menominee river into upper Michigan where it continued to do damage.Another tornado that touched down 8 miles west of Tomahawk (Lincoln co.) did significant damage, uprooting or snapping off thousands of trees along its path.  A house in the path of the tornado sustained major structural damage.  All outbuildings on the property were destroyed, a camping trailer was thrown 300 feet and a car was thrown into a tree, coming to rest at least 15 feet above the ground.  Two barns were also destroyed.The storms knocked out power to around 3,000 customers in the Tomahawk area (Lincoln co.) and about 600 customers in the Rhinelander and Crandon areas.
