This Date in Weather History

1987 - A major winter storm hit the Great Lakes Region, intensifying explosively as it crossed northern Illinois. High winds and heavy snow created blizzard conditions in southeastern Wisconsin. Winds gusted to 73 mph, and snowfall totals ranged up to 17 inches at LaFarge. The barometric pressure at Chicago IL dropped three quarters of an inch in six hours to 28.96 inches, a record low reading for December. Up to a foot of snow blanketed northern Illinois, and winds in the Chicago area gusted to 75 mph. O'Hare Airport in Chicago was closed for several hours, for only the fourth time in twenty years. High winds derailed train cars at Avon IN. Light winds and partly sunny skies were reported near the center of the storm, a feature typical of tropical storms.
