The path drawn at its surveyed width of 15 yards (0.01 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

What EF0 means. On the Enhanced Fujita scale, EF0 is light damage: shingles and siding peeled, gutters torn, branches broken, consistent with estimated gusts of 65–85 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

Someone driving along HWY 210 near Missouri City filmed a brief tornado in the field to the north of the highway. The visual appearance of the tornado was similar to a landspout, and with it being associated with a new updraft near a boundary, it was determined to be a landspout.

The wider storm

During the evening of June 11, a complex of thunderstorms ripped through eastern Kansas and western Missouri, including through the Kansas City Metro area. While the severe weather was fairly widespread, impacts were pretty low. There were some sporadic areas of enhanced wind where several reports of 80+ mph wind was received with wide swaths of tree destruction. The area with the highest concentration of the worst damage was in the Excelsior Springs area, where tens to hundreds of large healthy trees were destroyed, including at nearby Watkins Mill State Park. No injuries were reported, but the widespread nature of the damage and magnitude of the highest wind reports made this the biggest event of the severe weather season in the area.

Began near Missouri City (39.2434, -94.2713).
