Wider weather episode

During the afternoon hours a complex of thunderstorms crossed into Indiana from Illinois. A widespread swath of 65 to 75 mph winds occurred from central Terre Haute as far south as Sullivan, with the southeastward path then continuing into Clay, Owen, Greene, and Brown Counties before gradually beginning to weaken as it entered Lawrence and Jackson Counties.

The southern side of Terre Haute saw numerous large trees and power poles snapped or uprooted with widespread property damage to cars and homes along with thousands of power outages. Clay City and Jasonville also were areas of more concentrated damage with additional trees downed. The Bloomington ASOS measured 78 mph, which lined up with the town of Bloomington seeing the most significant damage from this event with a large swath of the town seeing widespread tree, power pole, and property damage.

Spotters later measured a 75 mph wind gust in far southern Brown county where additional tree damage was found but after this point the storm complex gradually weakened with the last damage noted in the Seymour area as the complex moved into an air mass that was more stable following weaker thunderstorms that had occurred earlier in the afternoon. The storm complex exited south central Indiana around 4:45 PM for a total event time of 2 hours between Terre Haute and Seymour.
