Some of the snow may linger for the Wednesday morning commute, creating some slippery conditions or poor visibility, especially in the early part of the commute, ABC7 Chicago meteorologist Larry Mowry said.

Temperatures Wednesday will be milder, with highs in the upper 20s to near 30. There will be another chance of some scattered snow showers during the evening commute as an Arctic cold front arrives.

Thursday will turn colder, with a high of just 20. But the core of the cold air arrives Thursday night and Friday morning and throughout the day on Friday.

Friday morning windchills could be as cold as 35 below zero.

Friday's high temperature may not get above subzero readings.

Saturday will also be very cold. Below-average temperatures are expected for the rest of the month, Mowry said.
