What EF3 means. On the Enhanced Fujita scale, EF3 is severe damage: whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, consistent with estimated gusts of 136–165 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 strong tornado developed in far northwestern Saline county Kansas around 744pm CDT and moved northeast into Ottawa County doing damage to several structures including a single family home. The tornado was well documented by numerous chasers and become wide with multiple vortices noted on video. The lack of DIs in this part of Kansas can be a challenge when it comes to rating tornadoes and using the traditional methodology of DIs yielded a EF3 rating. The tornado dissipated just to the southwest of Minneapolis, KS around 810 pm CDT.
