Another cold blast will hit the suburbs after a snowstorm tapers off early Sunday, forecasters say, and wind chills could dip to as low as 20 degrees below zero Monday morning.
The bitter temperatures are coming on the heels of a snowstorm that dumped about two to five inches for much of the area.
The National Weather Service issued a winter weather advisory that remains in effect until 9 a.m. Sunday.
A mix of heavy snow -- falling at a rate of up to an inch an hour before midnight -- and blistering wind on Saturday meant low visibility for drivers.
Some lake effect snow could blanket the far northeastern suburbs through Sunday night, according to the National Weather Service website.
The region has reached a brutal milestone: This winter is now the third coldest and snowiest on record.
