It is the one-year anniversary of the Groundhog Day Blizzard in Chicago.

The storm brought the area from central Oklahoma to the lower Great Lakes and central New England between 1 and 2 feet of snow spanning Jan. 31 to Feb. 2, 2011, affecting over 100 million people along its path.

The area from northeastern Missouri to northeastern Illinois was hit the hardest.

Wind gusts to 60 mph in the Chicagoland area brought travel to a standstill with haunting images of stranded vehicles in waist-deep snowdrifts along the Lake Michigan shoreline. The storm resulted in power outages, school closings and halted mail service for a time.

Chicago was buried under 20.2 inches of snow from the storm.

Hundreds of cars were stranded on Lake Shore Drive Wednesday, Feb. 2, 2011, in Chicago. A winter blizzard of historic proportions wobbled an otherwise snow-tough Chicago, stranding hundreds of drivers for up to 12 hours overnight on the city’s showcase lakeshore thoroughfare and giving many city schoolchildren their first ever snow day. A year later, temperatures are in the mid-50s and flirting with record highs for this date. (AP Photo/Kiichiro Sato)
