Here is what you can expect for the rest of the evening and overnight
6PM to 10PM: Strengthening northeast winds will continue to tap into Lake Michigan moisture and produce bands of heavy “lake enhanced” snow across Lake (IL), Cook and DuPage Counties. Some of these snow bands will venture as far west as McHenry, Kane, Will, Kendall and Counties . Periods of severely limited visibility are likely in the heavier snow bands. The most impressive snow totals will occur within 10 to 12 miles of Lake Michigan.
10PM to 3AM : As winds turn northerly, the snow will quickly taper or end over the western suburbs, but will continue over portions of Lake (IL), Cook, Du Page, and northern Will Counties. Winds will increase to 20 to 35mph, resulting in considerable blowing and drifting of the light, fairly fluffy snow. Travel may become downright dangerous in open or rural areas with near blizzard conditions possible.
6AM Wednesday: Any leftover snow in northeast Illinois will quickly come to an end. Periods of snow will continue across northwest Indiana through at least mid morning. Total storm accumulation for most areas of 7″ to 12″. A few locations in Lake(IL) and Cook Counties may see up to 14 inches.
