The historic Groundhog Blizzard that's been pummeling Chicago since late Tuesday has finally drawn to a close in the Windy City.

The Groundhog Blizzard now ranks third among the greatest snowstorms in Chicago's history, exactly what AccuWeather.com Expert Senior Meteorologist Alex Sosnowski predicted on Tuesday.

A total of 20.2 inches of snow has buried Chicago's O'Hare International Airport (the city's official weather observation site) through 10:30 a.m. CST.

The storm from late January 1967 sits atop the list of Chicago's biggest with 23.0 inches.

The 13.6 inches that fell alone on Tuesday made that day the snowiest February day on record. The previous record was held by Feb. 18, 1908, and its 11.5 inches.
