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

NWS storm survey concluded an EF-1 tornado touched down in southern Jefferson County. The tornado mostly produced tree damage and minor structural damage. The highest degree of damage occurred at its beginning where it caused two homes to slide off their foundations. The tornado had max winds of 105mph, was 4.9 miles long, and had a maximum width of 300 yards.

The wider storm

Ample instability paired with 50 kts of effective shear created a favorable environment for severe weather during the afternoon on June 7th. Convection that did develop came in the form of supercells, two of which produced tornadoes in southeast Missouri.

Began near Vineland (38.1141, -90.6799).
