The National Weather Service in Milwaukee/Sullivan will be conducting a survey of the southern Washington County area on Thursday.  Radar and spotter reports confirm a likely tornado touchdown in the area between Monches in far northern Waukesha County to the Hubertus area.  

Minor structural damage and tree damage was reported in the vicinity. 

The below image depicts the Milwaukee/Sullivan radar imagery at 4:53 pm.  The reflectivity is on the left and the likely tornadoes circulation is on the right. The circulation measured on radar was about 1300 ft above the ground.  This was about the time a Tornado Warning was issued for southern Washington County.
