The path drawn at its surveyed width of 75 yards (0.04 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

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

Brief EF1 tornado touched down near I-65. The survey crew found a mixture of straight line winds and a small area of a tornado embedded within. The tornado hit the Salem Rd area hard with extensive tree damage. A wheat field had distinct circulations quite visible.

This line continued south and southeast through Kentucky causing widespread damage and a loss of life. In the end, 3 tornadoes were confirmed with many other reports of downed trees, severe hail, property damage, and power outages.
