Event narrative

Corn stalks were blown over in a pattern consistent with damaging straight-line winds. Tree limbs, approximately 12 inches in diameter, were downed and power was out.

Wider weather episode

Northwest flow in the upper atmosphere allowed multiple waves to move across the area. The atmosphere had a high moisture content and was unstable. The waves interacted with the moisture and instability to produce the severe weather and heavy rain. Multiple rounds of thunderstorms moved over the same locations, creating the flooding problems. Several rounds of thunderstorms, from July 10th through the 13th, brought a tornado, damaging winds, large hail, and flooding to central Indiana. Mainly thunderstorm wind and flooding during this portion of the timeline.
