A series of severe thunderstorms moved southeast through southeast Wisconsin wtih powerful winds that toppled trees and power lines, as well as damaging some structures.  Damage to power lines resulted in the loss of electrical power to 12,000 customers in the Milwaukee area.  Northwest of Beechwood (Sheboygan Co.), the winds destoyed one small metal shed, and rolled over a propane tank.  Northeast of Ootsburg (Sheboygan Co.), the powerful winds toppled dozens of trees near Kohler/Andrea State Park, and damaged a couple homes.  In Washington County, a car and boat in Hartford were damaged by toppled trees, and a shed near Jackson was blown down.  Heavy rains associated with training thunderstorm cells created urban flooding in the city of Kenosha when .71 inches of rain fell in only 11 minutes (at the rate of 5.07 inches per hour).  Likewise, urban flooding developed in the city of Sheboygan when 1.81 inches of rain fell in 70 minutes ending at 1910CST (...and 3.57 inches in past 5 hours).  Synoptically, a mesoscale convective system moved southeast through Wisconsin overnight on the 7th and in the early morning hours of the 8th.  The trailing edge of this system brushed Sheboygan county with isolated severe weather at mid-day.  The outflow boundary left over from the MCS focused new thunderstorm development between Fond du Lac and Milwaukee as the low-level jet intensifed while a short-wave aloft moved through the area.
