Overview
|
Hot and humid conditions were found across the Midwest on Thursday, July 21, 2016, as a warm front lifted north into the upper Great Lakes. A storm complex developed over southern Wisconsin during the evening and tracked southward into northern Illinois and eastern Iowa during the late evening of July 21 and early morning of July 22. Some of the stronger thunderstorms brought 50 to 70 mph winds over Stephenson, Jo Daviess, and Dubuque counties downing power lines and trees. Widespread rainfall was also common with most areas receiving over an inch of rain in a short amount of time. The highest rainfall amounts fell over southeast Iowa and west central Illinois. |
