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

The tornado touched down in a subdivision southwest of Eureka in rural St. Louis County where it caused minor tree damage.

The wider storm

During the afternoon and evening of April 18, 2024, discrete supercell thunderstorms developed along a cold front moving through the bi-state area. These storms were initially capable of producing large hail and damaging wind gusts, but became tornadic as additional thunderstorms formed along the front. Due to the additional thunderstorms, storms congealed into a QLCS that impacted the St. Louis metro area. The QLCS was responsible for a tornado and straight line wind damage in this area. Fortunately, no injuries or fatalities were reported with these thunderstorms.

Began near Allenton (38.4640, -90.6650).
