An unseasonably warm and moist air mass was in place across the region during the morning hours of March 1st. Showers and thunderstorms developed across the Ohio Valley during the early morning hours as a strong low pressure system lifted northeast into the Great Lakes region. These storms produced heavy rain, large hail and several tornadoes. A squall line then moved through the region during the mid morning hours ahead of an approaching cold front. These storms resulted in damaging winds and additional heavy rain.

On Kentucky 989 just west of Burtonville, the top third of a silo was destroyed and blown to the east toppling onto another structure. Also, two other barns were destroyed. Several large trees were blown down or uprooted in the southwestern part of the county. Also, a few large, very well constructed barns were shifted 6 to 8 feet off their foundations with the opposite walls severely buckled. One of these barns had the roof completely blown off and large sections of the siding missing. All the debris from the above barns was scattered in fields to the east. Several smaller barns in this same area were completely destroyed.
Numerous trees were downed along Buck Lick Branch Road, five miles south-southeast of Tollesboro. Several homes in this neighborhood had minor damage. A brick home had the roof completely blown off.

Also, on the front of this same house, a large window facing west was blown into the house along with the front door. This allowed the wind to enter the house to do further damage. The roof was lifted but not detached. The force of the wind inside the house caused the brick foundation on the north side of the house to bulge and fail over a significant area. Debris from the house and associated shed was scattered into a field to the east of the house.
