This was a multi-round severe weather event. The first round started around 6pm with discrete cells and a few clusters moving from Knox, IN to Hillsdale, MI until around 9pm. The second round featured additional isolated development along a boundary draped across the northern CWA 9P-1A. The third round associated with the primary cold front swept across the CWA 1AM-5AM.
