We're under a Winter Weather Advisory for some snow this afternoon into the overnight hours. The heaviest snow will be in a narrow band to our SE -- there was some uncertainty overnight as to the exact track but it does look like we're only going to get sideswiped in Chicago. The most likely situation is an inch or two this afternoon/evening and another inch or two overnight for areas from the southern suburbs into the city. Amounts will be light to the north and west, so the north side of the city, northern burbs and far western burbs may only see an inch or less total. Some lake enhancement is possible along the lake (especially SE Chicago toward the IN border) so 4-6" is possible there.
The snow this afternoon and tonight will be heavy and wet due to temps in the low 30s. It could also fall heavily at times, dropping visibility to low levels. Roads and airports will be affected.
The snow should end by daybreak Sunday. It will be windy though, and temps will drop through the day. Another shot of snow arrives Monday -- it will be light but potentially disruptive to the evening commute.
Behind that will be some cold air. It will be nothing like recent winters' cold outbreaks but it will still be much colder than anything we've had yet this season. Highs will be in the teens Sun-Wed, but beyond that the pattern moderates. There are no extended cold-air invasions on the immediate horizon beyond midweek.
