How Low Did Temps Go Overnight? / More Bitter Cold This Weekend / Snow Possible Monday

It’s been cold and that cold is here to stay -- at least, through the weekend.

The National Weather Service this morning reported the lowest wind chill reading for a suburban town just before 9 a.m. on Friday at O’Hare Airport, -16, with several other towns, including West Chicago, DeKalb and Wheeling, reporting wind chills as low as -14. Meanwhile, temperature readings over the past 24 hours have been … very cold. The DeKalb Airport reported a temperature of -2 while the Waukegan and DuPage airports recorded a low temp of -1.

Coming off a bitterly cold start to the New Year, it will be much of the same this weekend.

Wind chills are expected to remain at or below zero throughout the day on Friday. An elevated risk for “excessive cold” is in the forecast for the Chicago suburbs for Saturday and Sunday as well.

A “warm up” is expected for the start of the work week with temps reaching into the 30s on Monday and into the 40s on Tuesday.
