Part of the tornado outbreak of December 10–11, 2021 and tornado outbreaks of 2021

During the late evening of Friday, December 10, 2021, a violent, long-tracked, EF4-intensity tornado, sometimes referred to as the Western Kentucky tornado,[3] Mayfield tornado,[4] or The Beast,[5] moved across Western Kentucky, United States, producing severe-to-catastrophic damage in numerous towns, including Mayfield, Princeton, Dawson Springs, and Bremen.[2] This tornado was the second significant tornado in an exceedingly long-tracked tornado family; it began just inside northern Obion County, Tennessee – a few miles after another long-tracked tornado that traveled through northeast Arkansas, the Missouri Bootheel, and northwest Tennessee – and dissipated in western Obion County.[6] After crossing into Kentucky, the tornado moved through eleven counties of the Jackson Purchase and Western Coal Field regions, at times becoming wrapped in rain during its almost three-hour lifespan that covered 165.6 miles (266.5 km). It was the deadliest and longest-tracked tornado in an outbreak that produced numerous, strong tornadoes in several states; this tornado caused 57 deaths.[2]

Early estimates suggested the tornado family, which some media outlets described as a "Quad-State tornado" due to the storm's long track and similarity to the 219-mile (352 km) Tri-State tornado of 1925, might have traveled 250 miles (400 km) on the ground, making it the longest-tracked tornado in history.[7][8][9] Storm surveys found the majority of the storm's path consisted of two separate EF4 tornadoes, and three weak, short-lived tornadoes in between them in northwestern Obion County, Tennessee. The parent supercell that produced the two EF4 tornadoes, and eleven tornadoes in total, later became known as the Quad-State supercell.
