The first city on the list where the yearly average low dips below 30, Grand Forks is home to the University of North Dakota and an Air Force base and sits along the Red River, which flooded the town in 1997. The town rebounded despite the nippy temps and 41.6 inches of snow on average each year. The lowest temperature on record is -46.
