Illinois Weather Trivia for August 6th

8/6/1977
Severe thunderstorms produced nearly 20 tornadoes in Sangamon and Christian Counties. Many of these only affected open fields. However, one tornado did cause extensive damage near and east of Chatham. One tornado just south of Lake Springfield was unusual in that it had a clockwise rotation, in contrast to the usual counter-clockwise rotation found in tornadoes. The thunderstorms that produced these tornadoes caused a large swath of destruction from strong winds extending from southwestern Morgan County east to far southwestern Macon County.
