The Fargo F5 Tornado of 1957 - The Science Behind the Slow-Moving Monster

On June 20th 1957, a powerful F5 tornado tore through northern Fargo North Dakota, killing 12. While a somewhat rare occurrence for a violent tornado at that northerly latitude, it was photographed and filmed by dozens of onlookers, resulting in the most well-documented violent tornado of its era. Although often overlooked in the history of violent American tornadoes, it played an important role in the development of the Fujita scale, and was critical in providing empirical evidence of mesocyclone structure, of which features like wall and tail clouds had yet to be officially named. Today we will examine the conditions that caused this tornado, the lives that it affected in Fargo and beyond, and pour over Dr. Fujita’s fantastic detailed analysis of the event that was, quite frankly, way ahead of its time.
