What EF1 means. On the Enhanced Fujita scale, EF1 is moderate damage: roofs badly stripped, mobile homes pushed off foundations or overturned, windows broken, consistent with estimated gusts of 86–110 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

What the National Weather Service wrote

The tornado continued to move east-northeast from Canadian county. The tornado continued from the north side of Lake Overholser and crossed NW 39th street, damaging several bleachers next to the baseball field. Damage to trees was also noted at this location, with one tree falling on a gas plant. About 50 residents had to be evacuated due to the gas leak. An apartment complex was sustained some damage near NW 50th and Grove streets. Tree damage continued along the tornadoes path until it finally lifted near NW 60th and Meridian Avenue. One indirect injury was reported with the tornado. A Bethany woman broke her leg while she was running toward her storm shelter. No other injuries were reported. Monetary damages were estimated.

The wider storm

A strong upper level low pressure system moved into southwest Oklahoma, and continued moving east throughout the day. Extremely strong lift ahead of the storm system and abundant moisture allowed for widespread showers and thunderstorms to develop over much of Oklahoma. The better chances for severe convection was located along and south of a stationary boundary that setup near Interstate 44. Severe thunderstorms developed during the afternoon hours south of the boundary, with large hail, flash flooding, and tornadoes reported. Several tornadoes were reported in the Oklahoma City metro area during the evening rush hour, with damage reported from Yukon through the northern portion of the city. Other tornadoes were reported south of the city, with damage also reported in this area. The slow movement of the precipitation quickly added up, with widespread amounts of at least two to four inches of rainfall. Flash flooding became a concern as the afternoon progressed, with several reports around central Oklahoma of roads being closed. The upper level storm system moved east during the evening, with the precipitation moving east as well. Monetary damages were estimated.

Began near Bethany (35.5183, -97.6646).
