Winter Weather Advisory for 1 to 3-inches of snow Wednesday across northern Illinois counties adjacent to Wisconsin

A Winter Weather Advisory (purple-shaded area on the highlighted map) 1 to 3-inches of snow from 10AM Wednesday to 1AM Thursday in northern Illinois counties along and adjacent to Wisconsin has been issued by the Chicago National Weather Service Forecast Office.  Counties under the Advisory are Winnebago, Boone, McHenry, Lake and also Ogle.

Initially a band of rain and sleet will spread over the area from the west Wednesday forenoon. Then as colder air follows across northeast Illinois, precipitation will change over to a moderate accumulating wet snow. Temperatures will fall through the 30s and the sleet/snow will begin to stick on pavement, creating hazardous/slick travel conditions mainly during the afternoon/evening commute.

While heaviest snowfall will occur in the northernmost Advisory area, sticking snow will likely make for slick/hazardous driving/travel conditions in the City of Chicago and as far south as the Interstate-80 corridor.
