More snow expected with bitter cold Monday

The deep freeze expected to hit the Chicago region later today, dropping temperatures well below zero and wind chills to dangerously low levels, could be accompanied by more than six inches of snow beginning Monday night, forecasters said Sunday.

The National Weather Service issued a hazardous weather outlook Sunday predicting that some parts of the area would see more than a half foot of snow that, combined with high winds, could make for dangerous travel conditions Tuesday and Wednesday.

The weather service also issued an advisory Sunday calling for wind chills to fall between 20 and 30 degrees below zero beginning around midnight and continuing through Monday afternoon. Frostbite can occur in a matter of minutes under such conditions, according to the weather service.

A snowstorm is expected to begin Monday night and continue into early Tuesday, dumping a half foot or more of snow on some areas, the agency predicts.

Wind chills of 20 to 35 below are forecast late Tuesday night through Wednesday night, and strong winds could result in significant blowing and drifting snow Tuesday afternoon through Wednesday, especially in open areas where visibility could be severely reduced, the weather service outlook predicts.
