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

The National Weather Service in Louisville, Kentucky conducted a storm survey in Scott County, Kentucky of storm damage that occurred early Monday morning.

The survey team determined that a tornado touched down just southwest of the Parkers Mobile Home Park in Stamping Ground. The initial touchdown was in a wooden fenced area with uprooted trees and significant damage to the wooden fence. Wind speeds were estimated to be between 80 and 85 mph initially.

The tornado increased in speed and diameter, striking the mobile home park causing

significant damage. Trailers were lifted off their foundation, some trailers were flipped

over and or turned in a different direction. Insulation and metal siding from the trailers

were thrown up into the trees. Deck pieces were thrown and impaled into the ground, trees were twisted and snapped, and numerous air conditioner units were thrown several feet. The tornado increased to around 95 mph with a width of 60 yards.

The most obvious signs of a tornado were outbuildings were picked up and thrown upwind, with insulation on both sides of the buildings.

The damage direction from the trees, and insulation from mobile homes ranged north to southeasterly.

The tornado became more of a skipping tornado as it moved to the east with the last damage being some power poles and trees at the corner of Edgewood Way and 227.

Just east of Stamping Ground, the survey team found a significant area of straight line winds along Duvall Station Road. A third of a mile swath of concentrated wind damage occurred 2 miles east of Stamping Ground.

It started out in a grove of trees with large branches and trees knocked down all facing from the southwesterly to the east northeast direction. Wind speeds were estimated initially to be 65 to 70 mph. A well constructed barn had its roof panels ripped off and doors blown in. Metal sheeting from the barn was thrown up to 500 yards down wind. Two other barns on the other side of the road had similar damage. Shingles from two family homes were thrown a hundred yards. Wind speeds from the well constructed barn, were determined to be 80 mph. The damage area was about a quarter mile by a third of a mile.

The National Weather Service would like to thank Scott county emergency manager Mike Hennigan for his assistance with the survey.
