| Episode Narrative | On the evening of Friday, December 10, 2021, a potent storm system moving across the central United States resulted in significant long-track tornadoes. A violent EF-4 tornado began in far northwest Tennessee, and moved across western Kentucky, resulting in dozens of lost lives and a swath of destruction. The tornado was on the ground for 128 miles within the NWS Paducah forecast area, and the total path length was about 165 miles from Obion County, TN to Breckinridge County, KY. Another long-track EF-3 tornado started in Dyer County, TN, and traveled about 125 miles through northwest Tennessee and into Christian and Todd Counties in western Kentucky. A strong upper-level trough over the western Plains induced a deepening surface low that tracked northeast across the Iowa/Illinois border. A very strong and deep southwest wind flow brought moist and unstable air into the Tennessee and lower Ohio Valleys. Record high temperatures were recorded, including a high of 73 at Paducah. The combination of very strong winds aloft, unseasonably warm conditions, and a strong low pressure system were ideal for this tornado outbreak. |
| Event Narrative | This historic EF-4 tornado was associated with a very long-track supercell that originally formed over eastern Arkansas. The supercell produced a nearly continuous tornado damage path from northeast Arkansas across western Tennessee and western Kentucky. The starting point of this particular tornado was in northwest Tennessee, northwest of Union City (see Storm Data, Tennessee, Western for information on this and other tornadoes associated with the supercell). This tornado crossed from Caldwell County into Hopkins County near the city limit of Dawson Springs, which straddles the county line. The tornado produced catastrophic damage and some fatalities in Dawson Springs. About two-thirds of the city's homes were destroyed, and about a dozen fatalities occurred. There were at least 200 injuries. The core of the tornado narrowly missed the downtown Dawson Springs business district, but a large residential neighborhood on the north side of downtown was destroyed. This neighborhood is where the tornado obtained its maximum EF-4 rating in Hopkins County. A two-story apartment building was almost totally destroyed. Only a few first-story interior walls remained standing (DI 5, DOD 6). This apartment building is where the damage was assigned a wind speed estimate of 180 mph, the highest in the county. On the northern edge of town, over a dozen duplexes suffered complete roof loss. All exterior and interior walls of one of the units collapsed (DI 2, DOD 9). Most of the single-family homes suffered complete roof loss and the loss of most exterior walls (DI 2, DOD 8). In a few cases, there was complete destruction of residences (DI 2, DOD 10). On Highway 109 on the northeast side of town, a large retail structure with a long-span roof was destroyed (DI 12, DOD 7). Nearby, about a half dozen other smaller homes and businesses were demolished, including the loss of all walls (DI 9, DOD 9). Once the tornado exited the Dawson Springs area, it crossed Interstate 69 (formerly the Western Kentucky Parkway) about three miles northeast of Dawson Springs. A clearly defined wide path of nearly total tree destruction crossed the interstate. A house near the interstate suffered the loss of the roof and most walls, except for a few walls of small interior rooms (DI 2, DOD 8). Where the tornado crossed Highway 112, a few single-family homes were demolished, including the loss of the roof and all or most walls (DI 2, DOD 8-9). The tornado continued across heavily forested land until reaching Barnsley, a small community between Earlington and Mortons Gap on U.S. Highway 41. Several houses were demolished, including the loss of all walls (DI 2, DOD 9). In addition, a train was derailed and a 55-foot tanker car was thrown 20 yards from the railroad tracks (DI 29, DOD 1). The tornado then continued through a long swath of forest before crossing Interstate 69 midway between Madisonville and the Western Kentucky Parkway. Hundreds of trees were snapped at this interstate crossing (DI 27, DOD 4). A number of vehicles were thrown and destroyed across the county. The total number of affected structures countywide was estimated near 1000. A little over 500 structures were completely destroyed. Nearly total tree destruction was observed all along the path. The average path width was a mile. The tornado exited Hopkins County across the Pond River into Muhlenberg County about 6.5 miles east-southeast of Madisonville. |
