What EF2 means. On the Enhanced Fujita scale, EF2 is considerable damage: roofs torn off well-built houses, mobile homes destroyed, large trees snapped or uprooted, consistent with estimated gusts of 111–135 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

This tornado intensified rapidly after development, and there was a visual from a farmstead to the north of the tornado developing. A dozen large trees at the first homestead hit were downed, some thrown, and heavy outbuilding, garage, and home roof damage. Further there were other homesteads/farmsteads that had outbuilding damage, utility poles downed (in one case thrown), and many trees snapped.
