FARGO — How much snow could we potentially get from a single snowstorm in the Northern Plains? The heaviest single-storm snow records usually come from mountainous regions or downwind from the Great Lakes where local geography can contribute to ridiculous snowfalls of more than 4 feet. The record for one storm in the Black Hills is 114.6 inches in Lead over five days in 1998. Finland, Minnesota, got 47 inches of lake-effect snow over three days in 1994.
Away from the mountains and Great Lakes, records suggest that snowfalls of up to 4 feet are possible, although rare. A snowstorm dumped 45 inches on Gettysburg, South Dakota, in 1994. Another dropped 47 inches across northwest Iowa in 1965. The Blizzard of 1966 dropped 27.5 inches on Grand Forks and 30.5 inches on Devils Lake. Fargo's record snow is 24.5 inches in January of 1989.
