Area of snow is beginning to shift south and eastward early this morning. Motorists should expect areas of sharply reduced visibility and quick light snow accumulations resulting in slick road surfaces. Allow extra travel time and increase following distances this AM. pic.twitter.com/t9EKuZSYMG

To further emphasize the poor travel conditions in portions of northern & central IL overnight, check out webcam image from I-39 SB over Lincoln Bridge between Oglesby & LaSalle.
