If you've been putting off buying a real winter coat or perhaps a sassy balaclava, it's officially time to bundle up, Chicago.

Temperatures in the Chicago area again plunged below zero overnight Thursday, with morning lows hitting as low as -16 degrees in west suburban Aurora and -5 degrees at O'Hare International Airport, ABC Chicago reports.

The weather was even more brutal when the wind chill was factored in -- as wind chill readings dipped as low as -31 degrees at Aurora and Rochelle, according to the Chicago Weather Center. In the city, the wind chill at Midway Airport hit as low as -16 degrees and a wind chill advisory for the area expired at 5 a.m.

Whenever the temperature plunges below 32 degrees, the city opens up its six warming centers, which are open from 9 a.m. until 5 p.m., and libraries and park district buildings are also options for those looking to avoid the cold. The Chicago Sun-Times notes residents are urged to call 311 to locate the warming center closest to them.

Meanwhile, there is another chance for snow in Chicago's near future as temperatures rise slightly with expected highs of 28 on Friday and 32 on Saturday, CBS Chicago reports.

WGN's Tom Skilling offered this glance at what could be coming the city's way Friday night into Saturday:
