Overview

The last day of June and into the first day of July, saw a line of severe storms form out over the plains that quickly raced east across Iowa, Southern Wisconsin, Northern Illinois, Northern Indiana, and into Southern Lower Michigan.  These storms produced widespread wind damage, with reports of 60-90 mph winds; along with reports of hail and tornadoes back out in Iowa.  Southeast Michigan saw these damaging winds move through between 2:30 am and 5:30 am on the morning of July 1st.  Southwestern Oakland, southeastern Livingston, and parts of Washtenaw counties saw the most extensive damage as numerous trees and power lines were taken down.  The highest wind gust was reported in Wixom, MI at 74 mph!  These storms were later classified as a derecho by the Storm Prediction Center (SPC).  More information about the entire derecho event, along with the definition, can be found in the additional resources section below.
