An area of low pressure will quickly sweep across Iowa into IL during the day Monday, spreading a swath of accumulating snow across the entire area.
Right now, it appears as though the onset of the precipitation should kick off around daybreak or slightly before.
WEDNESDAY: Snow will move out after "Daybreak", and we will see quiet weather for most of the day.
After a wintry weekend, the Chicago area will see another round of snow Monday afternoon, leaving behind 3-5 inches in most locations.

One calling for heavy snow in northern CT and another for a mixed bag of snow, sleet, and rain in the south. A purely rain event is unlikely at this point for the Poconos. It looks like amounts would be light and the weather should improve again Sunday. Snow is likely everywhere before changing over to a period of ice (sleet and freezing rain) and then rain. While there could be some wintry mix at the onset, this looks like mostly rain for much of the area given the milder temperatures.
Thursday: Mostly sunny, with a high at 54.
The spot that really looks to luck out, depending how you look at it for this event, is the southern Jersey and DE areas of the region.

Wednesday, a chance of snow showers before 8 a.m.
The winter precipitation accumulations will have some impact on travel.
