An unseasonably strong upper-level disturbance interacted with a warm, moist airmass to spark scattered thunderstorms across Southeast Michigan between 3 and 8 pm July 8. These storms became severe across the Saginaw Valley and Thumb regions, with hail up to golf ball size, scattered wind damage, and localized rainfall amounts near 3 inches.  An EF0 tornado occurred near Pinconning.  The storms weakened upon spreading southward, but re-intensified over the western suburbs of Detroit. A concentrated swath of wind damage occurred from western Wayne County through the Downriver area, with numerous reports of trees down.
