A foot of heavy wet snow fell in a band northwest of Chicago

Occurring in two surges, about a foot of snow fell northwest of Chicago and just south of the Illinois-Wisconsin state line Sunday. Six to 7-inches of snow fell from Lee and Ogle Counties across the southern half of Winnebago, Boone into McHenry Counties for a couple hours mid-afternoon and then a more extended snow laid down another 6-inches over that area Sunday evening.

In McHenry County, Bull Valley reported 13-inches of snow on the ground this morning and Wonder Lake measured 12-inches. To the west Ashton in Lee County observed 12-inches, while nearly a foot was reported in northwest Ogle County at Oregon, Forreston and Mount Morris.  The cutoff to the north was quite sharp with Freeport noting only 2-inches and South Beloit 5-inches on the ground this morning. Amounts tapered off more gradually to the south with 8 to 10-inches across northern DeKalb and Kane Counties into northern Cook.

Snowfall tapered off rapidly in Chicago/Cook County from 9-inches in Arlington Heights, 7-inches at O’Hare to 4-inches at Midway and just an inch or two along the lakefront.
