Hail in Lawrence County, Indiana

A very favorable environment along and south of a slowly advancing warm frontal zone, included ample vertical wind shear and increasing instability, which was all ahead of a very strong cyclone slowly approaching central Indiana from the west. Three rounds of scattered to numerous thunderstorms ranged from a pre-dawn, mainly heavy rain event to a midday cluster of cells, with finally late afternoon storms over southern central Indiana. Despite several strong and at times rotating thunderstorms, each group of storms contained only 1-2 reports of severe weather, with each round of severe weather focused on Monroe County.
