Chicago is preparing for its first significant snowfall of the season, with a Winter Storm Watch in effect for Cook, Will, Porter, and Lake counties in Indiana. The weekend weather forecast indicates a mix of rain and snow is likely, especially on Sunday, as colder temperatures move in. Residents can expect blustery conditions and possible lake-effect snow, with projections for intense snow rates overnight into Monday. As we head into the weekend, temperatures are set to drop, leading to accumulating snow in the region. The National Weather Service alerts that this could be the first major snowfall across the Midwest and that people should brace themselves for an early taste of winter.
