A slow-moving supercell thunderstorm developed in southern Kalamazoo County, Michigan, on Wednesday afternoon, dumping hail as large as ping-pong balls as it moved slowly southeast. Hail drift accumulation reached at or nearly to 18 inches in some isolated sections of Vicksburg just after 4:30 p.m. Wednesday resulting in the destruction of large sections of soybean and corn fields near the small southwestern Lower Peninsula of Michigan community.
