A cold front moving through southern Wisconsin was the focus for tornadic development through the lunch hour.  Temperatures and dew points rose enough in the late morning to help fuel the strengthening of the rain along the front.  There were numerous tornadic debris signatures that developed, many of which appeared to be extremely brief which did no damage outside of lofting leaves into the air.  The main tornado for this event was the one that went through West Allis which mainly did tree damage as it came through.  No lightning was observed through this event.
