The path drawn at its surveyed width of 100 yards (0.06 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

Several outbuildings were damaged or destroyed. A dog kennel was picked up and destroyed. Several shallow-rooted trees were uprooted, and one tree was snapped. A carport was destroyed. There was minor roof damage to some homes, mostly shingles blown off. Porch columns on a home were shifted. There was light damage to a total of nine homes along State Route 94. Two car windows were broken by falling tree limbs. A power pole was snapped at the intersection of Highways 94 and 783. The average path width was 50 yards. Peak winds were estimated near 80 mph.

The wider storm

A line of thunderstorms intensified as it moved east from Missouri. The storms increased as they moved into slightly more unstable air associated with a strengthening low level jet. The storms were aided by the approach of a strong upper level trough. Despite weak instability, winds of 90 knots in the lowest 3 kilometers coupled with extreme shear values resulted in damaging winds and isolated tornadoes with the strongest storms. Ahead of the thunderstorms, strong southerly gradient winds gusted up to 45 mph, mainly along and southeast of a line from Owensboro to Murray.

Began near Lynn Grove (36.5927, -88.4261).
