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

An EF-1 tornado passed just to the west of the Smith Mills community in Henderson County. The tornado developed along JJ Utley Road. Traveling north-northeast along Greenlick Baptist Church Road, the tornado destroyed a farm outbuilding. The tornado crossed Kentucky Highway 359 just south of Smith Mills where several trees suffered extensive large limb damage. Continuing north-northeast, the tornado passed through a cemetery along Grandpa Jones Road where several large trees were snapped. The tornado diminished as it reached Kentucky Highway 136 just west of Smith Mills. Peak winds were estimated near 95 mph.

The wider storm

A strong storm system led to significant impacts. Heavy rainfall amounts of 3 to 4.5 inches produced areas of flash flooding, with numerous road closures. The heavy rain drove the Ohio River above flood stage at Uniontown. Very strong wind gusts occurred, ranging between 50 and about 70 mph. These were associated with both thunderstorms and gradient winds afterwards. The line of storms moved through during the late morning and early afternoon, and then very strong gradient winds continued for several hours afterwards through the afternoon. An indirect fatality occurred the following day during cleanup operations. A 69-year-old man in Calloway County was killed when a large branch landed on him while he was cutting up the tree. The magnitude and duration of this wind produced significant damage to trees, power lines, and other outdoor property such as fences. Soggy ground due to the excessive rainfall likely contributed to some trees being more susceptible to being blown over. Numerous power outages occurred, some lasting into the following day. Six tornadoes occurred along the line of thunderstorms across western Kentucky. The strongest was rated EF-2 just south of Paducah. Finally, the lowest barometric pressure of all-time was observed in Paducah (977.7 mb). The center of the record strong low pressure system tracked from the bootheel of extreme southeast Missouri northeast right along the Ohio River. Very strong southwest winds occurred on the back side of the low pressure system in the afternoon. Gusts were up to around 60 mph. A semi was blown over on Interstate 24 in Trigg County.

Began near Smith Mills (37.7700, -87.7800).
