PLAINFIELD, Ill. -- On Aug. 28, 1990, Chicago’s southwest suburbs were slammed by a freak of nature; a rain-wrapped, EF-5 tornado -- still the most powerful to ever strike the Chicago area. WGN Chief Meteorologist Tom Skilling covered the killer storm in 1990 that shook up Plainfield, Joliet, and Crest Hill, as well as the entire weather profession.
The Aug. 28, 1990 tornado was very unusual. That day was miserable; temperatures in the 90s, dew points in the low 80s and unstable air moving in a strange direction, northwest to southeast. It was a cataclysmic weather concoction that claimed 29 lives.
