The Chicago area was slammed Tuesday with its most significant snowfall of the winter so far.
As of late Tuesday afternoon, snowfall totals ranged from 1.5 inches at Midway International Airport all the way to 5.5 inches in northwest suburban Bull Valley and 5 inches in Lake Bluff in the north suburbs, according to the Chicago Tribune.
The National Weather Service is forecasting up to 7 inches of heavy, wet snow will fall by later in the evening, accompanied with wind gusts approaching 40 mph that will make for reduced visibilities on roadways.
In Lake and McHenry counties, a winter storm warning is in effect through 6 a.m. Wednesday as a total accumulation of snow in the double digits is possible in Chicago's northern suburbs, ABC Chicago reports. In Cook County, a winter weather advisory is in effect through 9 p.m., according to NBC Chicago.
The snow has meant the cancellation of more than 330 flights at O'Hare International Airpot and 170 at Midway International Airport, according to ABC. All Chicago Public Schools after-school activities were cancelled.
The city of Chicago sent out its full fleet of 284 snow plows to clear the streets -- including additional resources to the city's Far South Side, where residents were heading to the polls to vote in the special primary election to choose former Congressman Jesse Jackson Jr.'s successor.
Additional snow is expected to continue into the early Wednesday hours.
