The episode as NWS IWX wrote it up.
A highly unstable atmosphere was in place across the area with Most Unstable CAPES in excess of 4000 j/kg. Effective shear was sufficient, but on the lower end with 30 to 40 knots in the wake of a departing upper wave. A large elevated mixed layer helped keep most convection suppressed. A weak boundary was in place across northern parts of Indiana from earlier convection. A lake breeze from Lake Michigan developed and moved inland across LaPorte County, interacting with this the boundary and causing an isolated storm to eventually increase in intensity. Isolated large hail was noted with pockets of locally heavy rain.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
