The path drawn at its surveyed width of 35 yards (0.02 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

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 blew down a few trees and snapped limbs off in a couple of areas, but most of the tornado's track was across open farm fields.

The wider storm

A large storm system in the Rockies headed through the Plains into the upper Midwest on the 29th. Rain increased ahead of the system, and became widespread in Arkansas. Meanwhile, a cold front arrived from the west. Because the system was so far to the north, it did not give the front much push. The front slowed down, which prolonged the rain. The result was widespread flash flooding, which gave way to areal flooding and river flooding. Winds changed direction and speed up through the atmosphere, a favorable condition for tornadoes. However, instability was sufficient only in southern Arkansas for the development of tornadoes.
