August 18 Damage Survey Results

Scattered thunderstorms will diminish as they track across south central and southeast Wisconsin this morning. Then isolated to scattered storms should develop this afternoon and exit southeast WI by this evening. Depending on how much clearing we get between the two systems, a few strong to severe storms will be possible later today. Stay weather aware!

Damage surveys from the August 18 severe thunderstorms found multiple areas of 70-80 MPH straight line wind damage from western Washington County southeast into Waukesha County and the city of Milwaukee. One brief tornado was confirmed near the villages of Colgate and Richfield in southern Washington County, and was rated EF0 with maximum wind speeds of 80 MPH.
