From Smithville to Smithville Muni Arpt, this EF1 tornado ran 3.2 miles across DeKalb County on May 6, 2024, touching down at 4:23 PM CDT and reaching 150 yards wide. It killed nobody, and did $300,000 of property damage.
The rating scale
Tracks are drawn in the color of the rating. The Enhanced Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.
EF065 to 85 mph
Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.
EF186 to 110 mphthis tornado
Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.
EF2111 to 135 mph
Considerable damage. Roofs torn off well-built houses, frame homes shifted on their foundations, mobile homes destroyed, large trees snapped or uprooted, cars lifted off the ground.
EF3136 to 165 mph
Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.
EF4166 to 200 mph
Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.
EF5over 200 mph
Incredible damage. Strong frame houses swept off their foundations, car-sized missiles thrown more than 100 meters, steel-reinforced concrete badly damaged, high-rise buildings deformed.
Unrated
The survey recorded a tornado but could not put a number on it, most often because it crossed open country and damaged nothing a rating can be read from.

What the Weather Service recorded
A broken line of thunderstorm tracked eastward across Middle Tennessee on May 6, 2024. With plenty of instability and modest shear, these thunderstorms became strong to severe, especially across eastern Middle Tennessee. Several reports of wind damage and large hail up to two inches in diameter were received. Two tornadoes were also confirmed. One was an EF-0 near Lebanon, and the other was an EF-1 near Smithville.
An EF1 tornado touched down east of Highway 70 in northwest Smithville then moved east paralleling Allen Ferry Road. Numerous trees were broken, snapped, and uprooted along the road, and several farm buildings lost roofing. The tornado then curved southeast and caused the worst damage along Highway 56 north of Smith Road where dozens of trees were snapped and uprooted and a couple homes suffered significant roof, garage, and exterior wall damage. The tornado then lifted east of the highway. Damages are a rough estimate.

What this means
Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
