Another round of snow is expected Saturday across most of northern Illinois, with up to 5 inches possible in some regions and accompanied by single-digit temperatures.

Some uncertainty about exact amounts remains, with the greatest potential for hazardous travel near and south of Interstate 80, the National Weather Service said.

Cold temperatures will lead to slippery conditions, even in areas with light accumulations. Amounts of snow will diminish toward the Wisconsin state line.

Saturday will start with temperatures in the mid-20s, but those will slowly fall throughout the day into single digits, the National Weather Service said.

Overnight temperatures into Sunday morning could drop below zero, and wind chills as low as 20 to 25 below zero are expected.
