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

Tornado developed in the northeast corner of Andover and continued north-northeast into the southeast portion of Oak Grove, where it dissipated. Hundreds of trees were broken or uprooted, some of which fell on houses, sheds, and vehicles. In addition to performing a storm survey, drone video from the Sheriff's Office was viewed.
