What happened

The episode as NWS IWX wrote it up.

Synoptic and mesoscale conditions for May 5, 1999...A warm front extending from Dubuque Iowa to Columbus Ohio became the focus for scattered...strong convection by early evening. 00Z raobs from Lincoln Illinois and Wilmington Ohio revealed marginal instability and wind shear. Storms quickly developed by early evening with pea to marble size hail reported with several of the storms. Additional storms developed over southwestern Allen county, Indiana where a storm split was observed. The left moving storm began to accelerate to the north and exhibited supercell characteristics. This storm was responsible for all of the severe hail reports that evening as it moved from Allen county, Indiana northward to Hillsdale county, Michigan, were it finally dissipated.
