What EF3 means. On the Enhanced Fujita scale, EF3 is severe damage: whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, consistent with estimated gusts of 136–165 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

About a dozen homes were destroyed, and close to 150 others were damaged. An additional 20 public or commercial buildings were destroyed or condemned. Damage to commercial and public buildings, including churches and schools, was estimated near 10.5 million dollars. Residential structures sustained about 1 million dollars in damage. Two historic churches suffered severe damage. The steeple of one church collapsed into the sanctuary. About 125 people were in the church at the time of the collapse, including 25 where the steeple fell into the sanctuary. They all moved to the basement 5 or 10 minutes before the storm hit, sparing anyone from death or serious injury. On the west side of Owensboro, a man was trapped in his overturned mobile home. He received only minor injuries. A motel was heavily damaged, with nearly the entire roof blown off. Several guests at the motel were treated for injuries, mostly abrasions from falling debris. Almost every building at Brescia University was damaged, mostly to the roofs. Windows were blown out of the science building. Elsewhere, a delivery truck was overturned. Piles of debris from collapsed garages, warehouses, and roofs lined downtown streets during the cleanup. Tobacco warehouses downtown were destroyed or heavily damaged. The most serious damage was in a 12 to 15 square block area in and near downtown. Nearly all city streets were reopened and nearly all power was restored within a few days after the tornado. Peak winds were estimated at 155 mph where the EF-3 damage occurred in downtown Owensboro. The damage path began just northeast of the Owensboro-Daviess County Airport, then curved northeast through the riverfront area of downtown Owensboro. The average path width was 300 yards.
