Event narrative

Thunderstorm straight-line winds caused significant damage at Kasting Park. Baseball dugout had roof lifted off and cinder block wall knocked down. Aluminum bleachers were blown into stadium's fence. Only minor siding damage to onsite building. Damage was all laid out to the north and northeast.

Wider weather episode

Ample instability and low-level vertical wind shear across central Indiana combined with a warm frontal boundary approaching from the south to produce several rotating, supercell thunderstorms. These storms produced large hail within a two hour late day period over several of the region's southwestern to south-central counties

Soon after, a rotating cluster of thunderstorms crossed southern central Indiana during the evening and early morning hours. This relative small, yet intense, complex of storms produced a long-track EF-1 tornado from Illinois into Gibson and Knox Counties in Indiana, as well as isolated, locally intense, damaging winds that were mainly in southeastern central Indiana.
