Minnesota and parts of southeast Wisconsin are preparing for significant snowfall this week, with the heaviest accumulations anticipated on Thursday. Snow showers are expected to move in late Tuesday, leading to a dusting before a larger winter storm arrives. Residents in the Twin Cities area could see accumulations of 3 to 5 inches by Thursday, marking the first substantial snowfall of the season. Weather alerts have been issued due to the potential for slick travel conditions and significant snow, as meteorologists indicate the possibility of plowable snowfall. The weather pattern is expected to bring colder temperatures along with multiple chances for snow throughout the week, potentially affecting travel plans ahead of the holiday season.
