What happened
The episode as NWS MKX wrote it up.
Scattered severe thunderstorms popped up over parts of south-central and southeast Wisconsin, resulting in scattered damage reports. Downburst winds gusting to around 60 mph leveled large trees in parts of Green, Rock, and Walworth counties. The tree debris brought down more power lines in Janesville (Rock Co.), causing the loss of electrical power to another 500 customers. This was on the heels of the major macroburst which raked Janesville the day before. The main cluster of thunderstorms which developed over Green County displayed supercell characteristics and had a hook echo/BWER/mesocyclone as it moved east into Rock County. Funnel clouds were noted over Orfordville and Hanover (Rock Co.), but no tornado spin ups were reported. Low-level inflow into the storms was from the southwest/west. Synoptically, the storms developed ahead of a cold front found from eastern Iowa into southwestern Wisconsin. Air temperatures were in the lower to mid 80s with surface dewpoints in the lower to mid 70s. LI's were -5 to -8 and CAPES were 1500-2000.
