A weekend storm will dump a fresh layer of snow over the Stateline, and could create slippery roads tonight. Adjust your travel plans, especially if driving into Chicago or Indiana for the weekend.
The snow showers will last until midnight tonight. The worst of the storm will be in Chicago and northwest Indiana, so the Stateline will only be grazed with a couple inches of snow. Amounts west of Freeport will be under 1", with areas in between Freeport and Rockford picking up 1" to 2", including Oregon, Byron, Dixon, and Rochelle. Between Rockford and McHenry County, amounts will be between 2" and 3". Chicago and the suburbs pick up 3" to 5", with areas along the Lake Michigan shoreline southeast of Chicago potentially seeing over 6".
Despite the lighter amounts for Rockford and surrounding areas, beware of slippery roads overnight. It doesn't take much to make the roads slick, so don't be in a hurry to get anywhere starting this evening. Strong winds will kick in overnight, with wind gusts over 30 mph. This will create blowing snow, which will be a driving hazard in open areas and the countryside.
Once the snow wraps up after midnight, the temperature will plummet. Highs on Sunday will only be in the teens, or some 15 degrees below average. With wind gusts between 30 mph and 40 mph, the wind chill values will stay below zero. If you are outside long enough, frostbite may become an issue, so try not to be out for over an hour without the proper winter clothing on Sunday.
