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

A brief EF-1 tornado touched down just east of Leonard and moved northeast. The tornado caused damage to farm structures, homes, and trees along its short track before dissipating just west of Highway BB.

The wider storm

Several thunderstorms developed in northeast Missouri during the late afternoon of August 9th. These thunderstorms congealed into a single, discrete cell just before moving into Knox and Shelby Counties. As the cell pushed east, it produced two tornadoes and minor wind damage.

Began near Leonard (39.8877, -92.1455).
