From the morning of January 28th through late that night, a winter storm brought impactful snow and freezing rain to parts of northern Illinois. Rain and snow began moving into the area during the predawn hours of the 28th and continued into the overnight with the heaviest snow falling during the afternoon and evening. The hardest-hit areas wound up with 5 to 8 inches of snow in extreme northern and northeastern Illinois and up to a tenth of an inch of ice accumulation across portions of the Chicago metropolitan area. Both the snow and ice made for hazardous travel conditions with local media reporting several automobile accidents as a result. A winter weather advisory had been issued for most of the CWA with the area's northern-most counties later upgraded to a winter storm warning prior to the event. O'Hare Airport measured 2.3 inches of snow and 0.04 inches of ice accumulation. Rockford Airport measured 5.1 inches of snow.
