A potent cyclone crossed northern Illinois, bringing central Indiana into its warm sector.  This allowed very strong vertical wind shear courtesy of the system's strong low-level jet stream to combine with the warm sector's adequate instability, producing several severe thunderstorms.  Near the greatest shear and instability, small supercell thunderstorms produced severe straight line winds, with one supercell spawning two EF-1 tornadoes in Hancock County.
