Severe thunderstorms formed over west central Wisconsin and moved east across central and east central Wisconsin during the late evening and overnight hours.  As the storms moved east they dropped quite a bit of penny to quarter size hail, before producing three microbursts in Calumet county that caused significant damage.The most severe of three microbursts created a damage path from 4.5 miles southwest of Hilbert to 3.5 miles south of Hilbert.  The straight-line winds associated with this microburst reached an estimated 95 to 100 mph, damaging or destroying three barns and numerous agricultural buildings.  One of the destroyed barns was made of 12 inch by 12 inch timbers.  This storm also damaged roofs and downed trees and power lines.  Two large oak trees with no leaves were uprooted in the microburst area.  Hail the size of half dollars was reported shortly after the strong winds moved through.The second microburst resulted in a damage path from 3.5 miles south of Chilton to New Holstein.  The winds associated with this microburst were estimated at nearly 70 mph.  This storm damaged at least three barns, blowing the west end out of one of them and blowing a portion of a barn through a house.  It also knocked a tree onto a house and downed other trees that caused damage to power lines.  A park in New Holstein had several trees snapped off 6 feet or more above the ground.The third microburst moved out of Fond du Lac county and into far southern Calumet county, about 4.3 miles south of New Holstein, with winds estimated at approximately 80 mph.  This storm downed or damaged multiple barns, toppled trees, tore the roofs from garages, upended boats and campers and damaged a shed and a silo.
