The final in a series of upper level disturbances propagated northeastward across southern Wisconsin during the afternoon and evening of June 19th.  This impulse, combined with strong upper level jet dynamics and a very moist, unstable atmosphere, allowed for storms to redevelop across southern Wisconsin.  Bulk shear values of 50-60 kts, MLCAPE values near 2500 J/kg, and PW values near 1.8 allowed for a series of short thunderstorm lines to move through southern Wisconsin.  The result was wind damage, a tornado in Kenosha County, and widespread flash flooding.  Due to the heavy rainfall from earlier storms, some locations received 3 to almost 7 inches of rain in less than 24 hours.  Flash flooding occured in Kenosha, Walworth, Waukesha, Milwaukee, and Racine counties.

Compounding the  flooding problem was the loss of electrical service which meant sump pumps in homes didn't operate.  Basement flooding was a major issue.  WSR-88D Doppler radar rainfall estimates on top of a wet ground were on the order of 3 to 6 inches for a 24-hour period ending 2000 CST.  Some farm fields were probably flooded, per newspaper articles, but no direct loss estimates were available.  Therefore, a nominal $200K was estimated for the purpose of this documentation.
