Southeast Wisconsin is bracing for a significant snowstorm, leading to widespread school closures and travel disruptions. Heavy snow, accompanied by wind gusts up to 45 mph, is expected to create hazardous conditions overnight into Monday morning. The storm is causing snow to fall diagonally, severely impacting visibility and making driving extremely difficult. Roads are already covered, and snowplows are actively working to clear them. The snow, described as light and fluffy, combined with strong winds, is exacerbating the challenging conditions.
