What happened

The episode as NWS IND wrote it up.

Early in the afternoon of July 8, an squall line developed over northwest Illinois and accelerate southeastward across the IND CWA . Dew points in the mid 70s were pooled south of a stationary front that was located across Northern Indiana and the upper dynamics were strong for July with strong uni-directional shear present. These ingredients resulted in a derecho event during the late afternoon and evening across Central Indiana. Trees were down across most of the counties in the IND CWA. Structural damage was not widespread, however as it was limited to trees falling on cars and houses and broken windows at the Kokomo Courthouse. An 18 year old girl had her neck broken as a tree fell on her car.

What forecasters said that day
