Across Northern Illinois where the coldest conditions are expected, daily high temperatures during this period will likely be limited to the single digits, potentially slightly below zero for some areas at times. Nightly low temperatures will regularly be below zero, potentially well below zero at times.

In addition to the actual temperatures, very cold wind chills are expected daily/nightly. Wind chills by day will generally be between -10F to 5F, while wind chills by night will generally be between -30F to -5F. Colder wind chills are possible at times.
