EF1 tornado in Graves County, Kentucky

This tornado crossed into Graves County from Weakley County, Tennessee. The tornado initially paralleled the state line, where mainly tree damage occurred. Along Kentucky Highway 303, a home was damaged. The side porch was lifted. A gazebo and a playhouse were destroyed. A garage at the north end of the house sustained major damage. Small portions of nearby grape vines were impaled in the roof of the porch, and a stick was impaled in the house. As the tornado moved northeast, mainly tree damage occurred, with uprooted trees and large limbs down. There was some tree damage south of the path near Lynnville, which was from straight-line winds. Peak winds were estimated near 100 mph. The average path width was 75 yards.

A pronounced mid-level shortwave trough and associated 70 to 80 knot mid-level jet progressed northeastward from the southern Plains across Arkansas and Missouri. An associated surface low developed northeastward from southwest Missouri toward northwest Illinois. A gradual increase in the warm sector southerly low level jet occurred as the surface low deepened. Increasing vertical wind shear in the moist and unstable warm sector resulted in organized severe storms. The storms were organized into bowing lines with embedded supercell structures.
