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 formed near 143rd and Antioch doing damage to trees in residential neighborhoods in that area. The tornado then did damage to Overland Trail Middle School, blowing out over 20 windows at Mission and 133rd there were several power poles down, and the tornado likely dissipated near the Kansas Missouri state line near 130th Street.

The wider storm

On the evening of May 2, 2018 a line of strong storms moved through eastern Kansas. While strong storms occurred across the entire eastern part of the state, the strongest impacts were felt within the Kansas City Metro area, where a EF-1 tornado formed in Overland Park, causing a fair amount of damage in the form of widespread tree damage, some structure damage to local schools, and numerous power lines and power poles were destroyed. The line of storms continued into western Missouri, where they went on to produce more tornadoes and scattered wind damage.

Began near Morse (38.8740, -94.6922).
