Two rounds of scattered severe convection affected south-central and southeast Wisconsin on Sunday, July 6, 2003. The first round occurred during the morning hours and the second during the late afternoon hours.  Powerful, downburst, damaging, straight-line winds toppled large trees and/or power-lines, 4 weak tornadoes spun up, a separate funnel cloud was reported, and there were a couple occurrences of large hail.  Detailed descriptions of the four tornadoes can be found in separate reports.Probably the hardest-hit area extended from Middleton (Dane Co.) to Maple Bluff.  In the Maple Bluff area, 8 homes sustained minor wind damage, and a car and two boats were damaged by toppled trees or large branches during the morning round.  Wind gusts in the Maple Bluff area were estimated to briefly reach 65 knots (75 mph).  Lightning struck a home in Middleton, resulting in a roof/attic fire.  Near Clinton (Rock Co.) the powerful winds pushed a large tree on a home, resulting in minor damage.  At the Alpine Ski Resort south-southeast of East Troy (Walworth Co.), lightning struck a man holding a tent metal pole, resulting in serious injuries.  The bolt injured 7 other, adjacent individuals who were standing in ankle deep water.  Six of the eight people were hospitalized.  Near Sturtevant (Racine Co.) an apartment complex sustained major damage due to a lightning fire.  Heavy rains of 1.5 inches resulted in minor urban-type flooding in the Okauchee (Waukesha Co.) area.   All together, at least 3000 customers lost electrical power due to tree limbs falling on power-lines or lightning strikes.  Synoptically, an upper level low pressure system and vorticity maximum moved east-southeast through the Dodge County area, resulting in bands of thunderstorms.  The tornadoes occurred near the low pressure center where large-scale atmospheric circulation allowed for rotating updrafts in a few thunderstorms.This was the 3rd of five consecutive days with some kind of severe convection across south-central and/or southeast Wisconsin.  Synoptically, a series of short wave troughs in the upper atmosphere moved east across Wisconsin while a surface frontal boundary oscillated north and south across southern Wisconsin.
