The episode as NWS IWX wrote it up.
A frontal boundary worked north into northern Indiana during the afternoon. A moderately unstable atmosphere was located south of the front with favorable freezing levels and shear. An upper level system moved through the area interacting with this boundary, providing the forcing for thunderstorm development. Some of these became severe with hail, wind damage and some reports of flooding.

NWS Northern Indiana wrote its last area forecast discussion before the first event at Jun 10, 2:09 PM EST, 3 hours 37 minutes earlier.
