A Winter Weather Advisory for additional 3 to 5 inches of snow over the Chicago area is in effect this New year’s Day.
A Lake-Effect Snow watch continues for additional snow accumulations in counties adjacent to lake Michigan later tonight and Thursday.
At 7 a.m., weather radar indicates an eastward-moving, slowly expanding band of light to moderate snow along and south of the Illinois-Wisconsin state line. Two to three inches of snow could accumulate primarily to our north as this area of snow works it’s way east, while expanding south over Chicago by mid to late morning.
Another significant area of snow to our west is associated with a center of low pressure developing in Missouri. As that low pressure moves east into southern Illinois this afternoon, the large area of snow now over Iowa will spread east into Chicago and northeast Illinois/northwest Indiana. Significant accumulations of an additional 2 to 4 inches will probably be associated with this action – centering along and either side of Interstate-80.
As this Wednesday afternoon/evening system snow recedes east, the strong northeast winds are expected to strengthen the potential for lake-effect snows later tonight into Thursday.
