The path drawn at its surveyed width of 400 yards (0.23 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

At a large farming operation, a shed was thrown over the top of a farm shop, damaging the roof of the shop. In addition, an empty 12,000 gallon fuel tank was overturned and rolled out into a flooded farm field. Nearby, the foundation of a concrete block house was damaged. Along U.S. 65, limbs were blown down next to a church. At the Arkansas River levee, an irrigation pivot was overturned and torn apart.

The wider storm

The day of the 22nd began cloudy, chilly, and foggy across most of Arkansas. During the day, however, much warmer air surged northward across much of the state. In the evening, a cold front plowed into the warmth and moisture, triggering severe thunderstorms and seven tornadoes.

Began near Linwood (34.1347, -91.8409).
