ALYZAThe Chicago radar (KLOT), 83 km away, was scanning. The volume nearest the first event began at 21:44 UTC.
1 lightning. Local standard time, as filed.
A 57 year old man was riding a bicycle on Road 700 East, about one quarter mile north of Road 3100 North when he was struck by lightning. The man was pronounced dead at the scene a short time later.
As the offices recorded each death: direct deaths were caused by the weather itself, indirect ones by something it set in motion.
