Event narrative

Thunderstorm winds blew over large tree.

Wider weather episode

A meandering frontal boundary slowly advanced northward in the early pre-dawn hours on March 7th. This brought a near-record moist environment and adequate instability across southern central Indiana, which combined with a low level jet stream from the southwest to produce an eastward advancing line of thunderstorms with locally severe winds. Damage was most severe in Sullivan, Shelby and Jackson Counties where winds likely gusted to 90-100 mph amid small downbursts. Insufficient evidence was present to suggest any tornadoes occurred.
