The Upper Midwest is preparing for a significant drop in temperature as Arctic air descends from Canada late Friday. Residents should expect daytime highs to plummet well below seasonal norms, ushering in a noticeably cold weekend. Areas across the Dakotas and Minnesota may experience light snowfall, particularly north of the approaching low-pressure system. Strong winds will exacerbate the cold, creating a substantial wind chill factor. This Arctic blast signifies one of the first true winter-like conditions of the season for the region.
