CHICAGO (CBS)– After two days of snow, the winter weather continues with a deep freeze taking effect overnight.

Monday evening into Tuesday morning, First Alert weather models forecast lows in the single digits. Wind chills are expected to fall to minus 10 to minus 20 below zero.

The temperature drop could bring the coldest temperatures of the year.

Black ice will also be a concern due to snow accumulation on streets and sidewalks.

Cook County officials are warning residents to use space heaters with caution. The heaters should be unplugged when not in use and turned off before going to bed. It is also important to place heaters away from any flammable items.

It can be dangerous to stay outside as the temperatures drop.
