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

This tornado exited Van Buren County northeast of Rubek and entered Stone County east-southeast of Old Lexington. One house had its roof damaged and a window blown out, and another house had roof damage. The porch and the roof of a mobile home were damaged. Sheds were destroyed and barns were damaged. Trees and power lines were blown down. The city park at Fox suffered considerable damage.

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 Old Lexington (35.7152, -92.3778).
