Summary of May 6, 1965 Twin Cities Tornadoes

Overview

May 6, 1965 was one of the worst tornado outbreaks in Minnesota history. Six tornadoes affected six counties around the Twin Cities with 13 fatalities and over 500 injured. The tornado outbreak lasted three hours and caused $51 million in damage. There were four F-4s, one F-3, and one F-2. Two of the F-4s crossed paths, causing even more damage. These tornadoes developed due to low pressure in North Dakota/Canada and unstable air behind a warm front over the Twin Cities region.
