Update to Friday's Wintry Weather
Still watching Friday mid to late afternoon for light accumulating snow fall across the Stateline. Ahead of a deep area of low pressure in the southwest, energy will eject across the county ahead of the main low pressure system. As moisture is drawn in from two sources, the Pacific and the Gulf of Mexico, moisture levels will increase Friday late morning. Lift in the atmosphere will move into northern Illinois and southern Wisconsin in the afternoon and will allow for light snowfall at first with a chance for a rain snow mix later in the afternoon as temperatures start below freezing and then warm into the mid 30's. It will be a slushy wet snow, that may be hard to accumulate at first. Overall one to possibly two inches is possible, with smaller amounts closer to the Chicago area. Though a few spots could see locally higher totals. While it won't be a high accumulation, roads will be slick as snow falls at an inconvenient time during the evening rush along with additional holiday travelers. The snow wraps up before midnight.
