EF1 tornado in Muhlenberg County, Kentucky

This fast-moving tornado touched down near two older mobile homes, tearing parts of the roof off both homes and toppling trees. The tornado then moved east-southeast up a knoll, where it buckled the west-facing door of an attached garage. The side walls of the garage were blown out, including part of the cinder block foundation. Several large trees around the home were either uprooted or snapped. Patio furniture was scattered up to 100 yards to the east. The tornado continued over open pasture before tearing the roof and two walls off a metal outbuilding and uprooting several trees. Just before crossing Highway 189, the patio roof of a brick home was torn off and blown 100 yards to the northeast, along with tree damage. The tornado continued 200 yards east of Highway 189, where it snapped several tree trunks. Peak winds were estimated near 100 mph. This tornado was spawned by a supercell that originated over southeast Missouri and produced a 42-mile long EF-3 tornado from the Paducah area to Lyon County, Kentucky.

Clusters of supercell thunderstorms moved rapidly east around 50 knots across western Kentucky during the afternoon. Some of these storms produced tornadoes. Low level wind shear was very strong, with 0 to 1 km bulk shear near 50 knots. This shear was present amidst decent instability for late fall, with mixed-layer capes of 500 to 1000 j/kg. One supercell cluster moved east from the Paducah area along the Western Kentucky Parkway. The other supercell cluster moved east across the far northwest counties of Kentucky, passing south of Evansville and then across the Owensboro area. The storms initiated over Missouri along a pre-frontal low pressure trough, then moved east across the Lower Ohio Valley. Strong southerly surface winds ahead of the storms gusted up to 50 mph during the early morning hours. An off-duty meteorologist measured a gust to 50 mph in Calvert City in Marshall County.
