Hail in Bay County, Michigan

A powerful upper-level low pressure system dropped southward into the Great Lakes on Sunday July 27, sparking a good deal of severe thunderstorms in the warm, moist, and unstable air in advance of the system. Between 2 p.m. and 8 p.m., severe weather affected nearly all of southeast Michigan. The initial storm that affected portions of Midland and Bay counties from around 2:15 to 3:15 p.m. was a prolific hail producer, with hail up to 3 diameter (greater than baseball size) recorded near Midland. Later, another particularly strong storm moved across Oakland County between around 4:30 and 5:15 pm, dropping hail up to 2.50 diameter (tennis ball size) near the Highland/White Lake area, with wind damage reported over central and eastern portions of the county. The storms produced heavy rainfall as well, with a swath of 1-2 recorded over southern Oakland County. Wyandotte, in southern Wayne County, picked up 2.67 in 4 hours. Total damage across Southeast Michigan was estimated to be 100 million dollars from the severe wind and hail.
