What happened

The episode as NWS IND wrote it up.

Several supercell thunderstorms and a squall line moved across Central Indiana during the afternoon and early evening of October 24. There were numerous reports of large hail and downed trees as well as a brief tornado touchdown near Williams. Notable damage reports included semi's blown off the highway at several locations, a mobile destroyed at Wesport and several barns destroyed and roofs blown off homes at various locations. A very strong cold front and negatively tilted trough combined with very unstable conditions and strong wind shear allowed many of the storms to develop rotating wall clouds, however only 1 brief touchdown occurred.
