US National Weather Service Chicago Illinois
A strong storm system is expected to spread moderate to heavy snow across the area tonight into Saturday. It still appears the precipitation will start as rain by early this evening, before changing to snow by mid to late evening over far northern Illinois. The heaviest snow will fall north of the interstate 80 corridor and inland from lake Michigan. A total of 7 to 12 inches is forecast for north central Illinois, with amounts tapering off to only an inch or two across east central Illinois. The snow will abate from west to east Saturday afternoon, though strong northwest winds in the afternoon could still produce some blowing snow.
Significant snowfall expected for parts of Midwest
The first significant snow storm of the season is expected to develop across parts of the Midwest on Friday, from Nebraska to Michigan. Widespread amounts of 4 to 8 are expected, with as much as 6 to 12 inches possible for some locations.
Snow predicted to hit Des Moines, Milwaukee and Chicago. Cold rain is expected to change to snow Friday evening.
A snow storm is also making its way to Northern Michigan this weekend.
A Winter Storm Watch will go into effect late Friday night for all of the Central Lower Peninsula counties and Alpena, Alcona and Arenac counties on the Lake Huron shoreline.
This watch will be upgraded to either a “winter weather advisory” or a “winter storm warning” this afternoon per the National Weather Service. More likely than not, it will be a winter weather advisory, which means inconvenient travel is likely Saturday.
