The 23 Storm Team is busy tracking the first winter storm of the season for the Rockford region. Not only will this system bring heavy, sticking snow, it will also affect post-Thanksgiving travel.

A winter storm warning has been issued through 6 a.m. Monday by the National Weather Service for Winnebago, Stephenson and Jo Daviess counties in Illinois. Green, Rock and Walworth counties in Wisconsin are also under a winter storm warning. That one starts at 3 p.m. Sunday and goes through 6 a.m. Monday.

A blizzard warning will take effect at 6 p.m. Sunday for Boone, McHenry, DeKalb, Ogle, Lee, Carroll, and Whiteside counties in Illinois. This will go through midnight Monday.

For the majority of northern Illinois, 7- to 9-inches of snow is likely to fall. The area affected ranges from just east of Freeport, through Rockford and Winnebago County. This same accumulation will extend to Chicago's northern suburbs. Around Rockford, some places could see closer to 11" of snow, especially to the south and west.

We are also monitoring a line closer to Freeport in Stephenson County, where spots northwest of Freeport could receive between 2- to 3-inches of snow, while others receive much more.

Places near the Quad Cities could catch the brunt of this system, getting close to a foot of snow.

SNOW ARRIVAL: As the afternoon progresses, precipitation will turn to snow, with the heaviest falling in the mid-afternoon or evening. Drivers on Sunday will face slick spots, snow-covered roads and low visibility levels. The system will move out overnight and should be gone for the Monday morning commute.

HIGH WINDS: Winds will pick up on Sunday, gusting between 25 and 40 miles per hour.

POSSIBLE POWER OUTAGES: The heavy, wet snow could stick to power lines and trees, causing some power outages.

After the snow moves out, be ready for a temperature drop into the 20s for the next few days.
