Event narrative

Tree blocking State Road 3 in Hartford City.

Wider weather episode

Weak shortwave trough moving through upper Michigan combined with retreating outflow boundary from morning/early afternoon storms, which moved through northern Indiana/northwest Ohio, spurned new storm development from southern Wisconsin southeast through northeast Illinois by later afternoon. Storms were initially sub-severe and disorganized, but two main bowing segments, one along and north of the Interstate 80/90 corridor and another along the US-30 corridor, developed as cold pool strengthened, causing widespread damaging winds and flooding.
