About Tornadoes in Norman
This overview was written August 10, 2026. The tornado counts and notable-event figures elsewhere on this page reflect the latest data and may differ from this summary.
Calm weeks and volatile afternoons sit side by side in Norman's weather story. Much of the year passes quietly over central Oklahoma's open terrain, yet dry air sliding east off the high plains, humid Gulf of Mexico air streaming north, and the sharp dryline where they meet can turn a placid morning into an outbreak by evening. Fittingly, the NOAA Storm Prediction Center, keeper of the national severe-weather record, forecasts from Norman itself.
The archive reflects those sudden turns. September 14, 1957 brought an F4 tornado that ran 67.5 miles and killed 2 people, and on May 3, 1999 an F5 up to 1,430 yards wide carved a 37-mile path through the area, killing 36 people and injuring 583. EF4 tornadoes swept the vicinity on May 10, 2010, again on May 24, 2011, and once more on May 19, 2013, when 2 people died along a 23-mile track.
The rhythm is strongly seasonal. April, May and June form the prime window, when shear and instability align, and May recurs throughout the event list. Autumn brings a quieter echo — an F3 tornado on November 20, 1973, killed 5 people and injured 36 as a cold front crossed the state. For the present-day picture, the live tables and maps elsewhere on this page follow the documented record for the surrounding area as new storm surveys arrive.
