Overview
A strong upper level storm system overspread the region during the afternoon of July 20th resulting in rapid scattered thunderstorm development across northwest Indiana and southwest Lower Michigan. These storms increased in coverage as they moved across the remainder of northern Indiana during the afternoon and early evening. Pockets of damaging wind gusts were observed with the stronger storms, along with localized flooding. The thunderstorms eventually weakened across northwest Ohio where earlier day storms resulted in more stable conditions.Tornadoes: Page will be updated as new information becomes available
