Thunderstorm Wind — Decatur, Indiana

2022-05-20 · near Milford, Decatur, Indiana

Event narrative

Thunderstorm winds snapped a utility pole about halfway up at West Base Road and North County Road 500 West.

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.
