The Winter Weather Advisory for heavy snow has been updated to include counties adjacent to the Illinois-Wisconsin state line – thus all Chicago-area counties are now under the Winter Weather Advisory until 3AM CST Sunday morning. Latest reports indicate several observations of 2-inches-plus snowfall will likely occur over in the northernmost counties by the time snow ends from the west later tonight.
Late reports indicate S. Jacksonville in Morgan County (west-central Illinois) has received 14-inches of snow and Warsaw in Hancock County (also west-central IL) 11.1-inches. Mason City in Mason County has measured 12.5-inches.
A Chicago National Weather Service map forecasting possible additional snowfall before the storm ends here is posted below.
Following are a few recent snowfall reports in the Chicago area…

Map indicating additional snow fall expected this evening…
Snow will continue through the evening, then gradually diminish and end from west to east overnight. A Winter Weather Advisory for an additional 1 to 4-inches this evening – higher totals south of Interstate-80 will be in effect for all counties, except those adjacent to the Illinois-Wisconsin state line (see purple-shaded area on the headlined map).
Travel will be slick and hazardous over the entire area with deeper snow and more difficult conditions the farther south you go. Storm totals will likely range from about an inch or so along the Illinois-Wisconsin state line to nearly a foot as you approach central portions of Illinois.
Maps depicting projected snow totals across the area and the west-east extent of the Winter Storm warnings (pink-shaded areas calling for up to a foot of snow) and Winter Weather Advisories are shown below.
