Some northern areas could see three to six inches of snow, while areas further south could see a mix of precipitation that could create icy road conditions for travelers during the morning and evening commutes.
Even after that weather system moves out of the area, residents will have to deal with a different threat: bitter cold. Temperatures will plunge on Tuesday and into Wednesday, with wind chills potentially dropping to 35 to 50 degrees below zero in some locations.
In fact, Wednesday has the potential to be one of the coldest days in Chicago history with a projected high temperature of -8 degrees.

The lowest high temperature in Chicago history came in January 1994, when the mercury only rose to -11.
The coldest high temperature on January 30 in Chicago history is three degrees above zero, so the area could smash several cold-related records in the coming days.
