Winter storm moves into Chicago area

CHICAGO -- A Winter Weather Advisory is in effect for the Chicago area beginning Friday at noon until Sunday at 6 a.m.

A little light snow is possible early this afternoon, but then the potential for snow increases from there.

Unfortunately, moderate snow is expected to arrive during the afternoon/evening commute.

This could very well lead to treacherous conditions on area roads. Snow could be heavy at times this evening with accumulations of 1-4" possible by midnight.

The lighter amounts are expected to be south of I-80 with highest amounts near the IL/WI state line.

After midnight. the snow should decrease in intensity, but late in the overnight hours a chance for wintry mix arrives, mainly south of the city.

The chance for snow, sleet and freezing rain continues through Saturday morning. The precipitation should be lighter Saturday morning and could end for a time being. Minor ice accumulation could occur and cause slick roads, especially south of I-80.

The wintry mix is expected to change back to all snow Saturday afternoon and continue into the overnight hours.

Another 1-4" of snow are possible Saturday. Snow accumulation totals of 2-8" are possible. The lesser amounts are expected south of I-80 with the highest totals near the IL/WI. 4-6" are expected in Chicago.

On the heels of our latest winter storm, the temperatures will tumble. Highs in the mid to upper teens at midnight Sunday will be replaced with temperatures near zero for much of day. Wind chills of -15 to -30 are expected Sunday.

Brutally cold temperatures early Sunday night should rise slightly by Monday morning.

We should see highs return to the 30s by mid-week next week.
