Another Round Of Snow Friday Night Before 'Bitter Cold' Hits Illinois

ILLINOIS — Several inches of snow has already fallen across the Chicago area on Friday, and another round of snow is expected on Friday night, according to the National Weather Service.

Before the second round of snow, a rain and snow mix is expected north of I-90, and primarily rain for areas south of I-90.

There will be a transition back to all snow across the area later Friday afternoon and evening.

"Travel remains hazardous as roads are still partially snow and slush-covered from this morning's first round of snow," the weather service said.

A winter storm warning remains in effect for areas mostly west and north of Chicago until noon on Saturday. The winter storm warning that was in effect for Kendall, Grundy, southern Cook and Will counties has been cancelled, and a winter weather advisory will be in effect from 9 p.m. Friday until noon Saturday.

Wintry weather will continue after the winter storm ends Saturday, as "bitterly to dangerously cold temperatures" are expected through the weekend and into next week, the weather service said.

The cold will begin Saturday night through Tuesday night, and wind chills as low as 30 below zero are possible. At those wind chills, frostbite on exposed skin can happen in as little as 15 to 30 minutes, the weather service said.

Temperatures aren't expected to rise out of the single digits. The high for the day on Sunday and Monday is 6 degrees, and the high for the day on Tuesday is 5.

There will be a slight warm-up on Wednesday, but temperatures will still be below normal for the rest of the week, the weather service said.
