A winter weather advisory is currently in effect across parts of the Great Lakes and Upper Midwest, as a multi-hazard storm system threatens to disrupt post-holiday travel. According to the National Weather Service (NWS), the storm is expected to bring a mix of freezing rain, sleet, and snow from Wisconsin and Michigan into parts of northern Illinois, Indiana, and Ohio. Snowfall totals are forecast to vary widely, with the Upper Midwest expected to receive 1 to 3 inches, while areas closer to the eastern Great Lakes could see 3 to 6 inches, with locally higher amounts possible. Ice accumulation is a primary concern, with up to a quarter-inch expected in some areas, potentially leading to hazardous driving conditions and isolated power outages.
