CHICAGO — A Winter Storm Warning for heavy snow up to 8 to 10-inches (pink-shaded area in map) is in effect for the Chicago area from 9PM CST this Friday evening until 3PM CST Saturday afternoon. A Winter Weather Advisory for a lesser 3 to 6-inch snowfall total (purple-shaded area on map above) will be in effect along and just south of the Interstate 80 corridor into northwest Indiana.

Snowfall amounts will likely vary from 8 to 10 inches west and north to 3 to 6 inches along the Interstate 80 corridor to 1 to 2 inches far south. In Chicago due to the slightly warmer temperatures of the city and the close proximity of the 50-degree waters of Lake Michigan, amounts could vary from 6-inches or more to 2 to 4-inches in the Loop and along the immediate lakefront.

Low pressure moving east out of the central plains will approach our area with rain reaching western portions late this afternoon/early evening. As the evening wears on, rain will become mixed with and change over to a wet snow that will accumulate overnight into Saturday. The center of low pressure will pass to our south moving into Indiana with the snow gradually ending from the west on Saturday.

Travel will be increasingly difficult and hazardous tonight into Saturday as the snow builds up — take precautions to prepare for this early-season storm.
