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

A NWS Nashville Storm Survey concluded that an EF-1 tornado down southeast of Adairville, traveled 1.5 miles, and then lifted approximately 2.5 miles east of Adairville. Along its path, the tornado did minor roof damage to a house near Martin Rd. A home and an outbuilding had minor damage near Barnes Rd, along with several downed trees. The most significant damage happened just before the tornado lifted near Prices Mill Road, where a large barn lost a significant portion of its roof structure. Maximum estimated winds were 90-95 mph, and the max width was 50 to 75 yards.

The wider storm

The combination of a moist and unseasonably warm air mass and an approaching low pressure system and cold front brought multiple rounds of severe weather to central Kentucky during the early morning hours on March 1. In the end, there were 4 tornadoes across central Kentucky. In addition to the tornadoes, there were several areas of intense straight-line winds estimated up to 100 mph in places. The impacts included numerous areas of structural damage and downed trees. The widespread rain also brought several rivers into minor flood.

Began near Adairville (36.6590, -86.8350).
