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 occurred on the south side of Benton. The tornado crossed the old two-lane U.S. Highway 641. Peak winds were estimated near 105 mph. A tire business was destroyed. A large portion of a block wall collapsed, and much of the roof was blown off. Two outbuildings sustained loss of roofing material and damage to a wall. Two homes had fascia, siding, and shingle damage. Two garages lost some shingles. Windows were cracked at a church. Several trees were snapped. The average path width was 110 yards.

The wider storm

Numerous thunderstorms preceded a cold front as it moved east across the Mississippi Valley. A 500 mb trough over the southern Plains advanced east-northeast, providing support for thunderstorm development. Isolated to scattered damaging wind gusts accompanied the well-organized line of thunderstorms. A couple of brief tornadoes accompanied the quasi-linear convective system.

Began near Walnut Grove (36.8302, -88.3529).
