CHICAGO — A Blizzard Warning is now in effect for Cook County and the Chicagoland area, as well as DuPage, Will, Grundy, Lake, McHenry, DeKalb, Kane, Kendall and LaSalle counties Sunday evening into Monday morning.
The storm is expected to ramp up between 6 p.m. and 9 p.m. Sunday. Snowfall totals are expected to range from about 12 inches north and west of the city to 2 to 4 inches well to the south and east.
During this time, travel could be very difficult due to reduced visibility, as snowfall rates of more than 2 inches per hour are possible. These heavy snows hold potential to cause blackouts, as branches fall from trees and onto power lines.
North to northeast winds will be increasing to as high as 40 to 50 mph, causing whiteout conditions along with blowing and drifting of the snow, prompting the blizzard warning issuance. The strong northeast winds will also generate high waves on Lake Michigan that will result in lake shore flooding.
Strong wind gusts in excess of 50 mph could potentially continue for several hours Sunday night.
