The path drawn at its surveyed width of 1,000 yards (0.57 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

What EF3 means. On the Enhanced Fujita scale, EF3 is severe damage: whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, consistent with estimated gusts of 136–165 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

This was the fifth of five tornadoes spawned by the same supercell thunderstorm. This tornado passed through the south side of Shoffner. A church was destroyed and a power substation was damaged. A hangar at a flying service was destroyed and an aircraft used for agricultural application was damaged. A mobile home was overturned and destroyed. Significant roof damage occurred to homes. A grain elevator was badly damaged. An irrigation pivot was overturned. Outbuildings were destroyed or damaged. Trees were blown down.

The wider storm

Moisture from the Gulf of Mexico surged into Arkansas at the end of April, so conditions in the state became warm and humid. On the 30th, a strong area of low pressure aloft approached from the west, resulting in the development of thunderstorms. Wind shear, a change in wind direction and speed with height, was present. This created a favorable environment for the formation of tornadoes.

Began near Weldon (35.4460, -91.2711).
