Violent thunderstorm blasts Stockton in far northwest Illinois Friday evening

National Weather Service Coop Observer Fred Demeter sent us these pictures of a violent storm that hit near Stockton in Jo Daviess Couny in far northwest Illinois Friday evening around 6:10 p.m. Hail was up to 2 inches in diameter and dented the top of a trailer and a truck. High winds downed a large willow tree that smashed a fence as it fell.
