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

An EF-1 tornado with winds estimated at 100 mph crossed the Missouri and Arkansas state line south of Pontiac, Missouri. Damage in Missouri consisted of the uprroting and snapping of trees.

The wider storm

An approaching shortwave trough and accompanying surface low tracked northeast of Arkansas and into southern Missouri. A modest instability and high shear environment with very moist airmass supported widespread convection and a few supercells. A tornadic supercell tracked northeast from north central Arkansas through Ozark and Howell counties in Missouri producing five tornadoes.

Began near Pontiac (36.4978, -92.5886).
