Records taken from the Storm Prediction Center archive data, "Storm Data", and data from the National Weather Service office in Norman. Data modified as described in NOAA Tech Memo NWS SR-209 (Speheger, D., 2001: "Corrections to the Historic Tornado Database").

Historic data, especially before 1950, are likely incomplete.
