What happened

The episode as NWS PAH wrote it up.

A bowing line of thunderstorms raced eastward across Illinois and Indiana at 45 mph. The trailing southern end of the bow crossed southwest Indiana, accompanied by locally damaging winds. The line of storms may have been initiated by a weak upper level disturbance entering northern Illinois. As it moved east, the line gained strength as it fed on a very moist and unstable air mass.

What forecasters said that day
