Severe thunderstorms erupted along the I-94 corridor during the late afternoon on Friday, July 23rd. These storms continued into the evening hours as they sagged south into Indiana and Ohio. A National Weather Service survey confirmed one EF0 tornado in Augusta Township in Southeast Washtenaw County. A National Weather Service storm survey was also conducted from Saline to Milan, in Washtenaw County. The result of this survey concluded that the damage in this region was due entirely to strait line winds. Based on the damage, wind gusts were estimated between 70 and 75 MPH. This caused extensive tree damage, especially in Saline. There were many reports of high winds and associated wind damage across the rest of Washtenaw County and across portions of Wayne and Northern Lenawee Counties. Some of the highest wind gusts were estimated or measured to 80 mph south of Dexter, Augusta Township and in Taylor. 1 to 3 inches of rain also fell near the I-94 corridor which also brought a few localized flash flood events.
