Temps drops below zero in Chicago for first time in nearly a year

CHICAGO - A wind chill advisory was issued for some areas of the Chicago area Friday morning as the temperature dropped below zero for the first time in almost a year.

The official reading at O’Hare International Airport hit minus-1 at 8 a.m., the first time the temperature has been below zero since Feb. 14, when it got down to minus-5 , according to the National Weather Service.

Chicago typically logs about 8 mornings each year with lows below zero.

The Wind Chill Advisory remains in effect for mainly western and far southern portions of our area until mid-morning. Wind chills will be -15 to -25 in those areas and not much better anywhere in Chicagoland. 

Highs will only reach the mid teens-just like yesterday. Skies will be mostly sunny anyway.

Tonight, temperatures will dip a few degrees before leveling off then actually beginning a rise toward dawn.  

Highs tomorrow will be close to freezing but won’t be reached until very late in the day or evening.  

Some light freezing rain seems the most-likely type of precipitation but quite frankly there could be a mix across our area. Just enough to make for slippery spots tomorrow night. 

A cold front slides through early Sunday morning and temperatures will fall through the day even as skies clear. 

There are growing signs of some light snow (inch or so) for some of us on Monday. Something to monitor for possible commute impacts.
