The path drawn at its surveyed width of 100 yards (0.06 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

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

A tornado was embedded within a large bow echo (curving line of thunderstorms shaped like a backwards C). The tornado knocked down trees and power lines.

The wider storm

Unstable air, fronts meandering in the state, and areas of low pressure aloft contributed to severe weather, including a few tornadoes.

At Arkansas Post (Arkansas County), the rain contributed to making it the wettest May ever recorded.

Began near Rose Hill (33.6790, -91.8181).
