2021 Tri-State tornado

Last updated May 29, 2024

11⁄2 hours later; additional clusters of thunderstorms developed over southwestern Missouri (forming between Bolivar and Carthage, eventually back-building into northeastern Oklahoma) and central Arkansas (forming southwest of Hot Springs) between 5:00 and 5:30 p.m. CST (23:00–23:30 UTC).^[8] Though this activity lacked much vigor at its onset due to a strong capping inversion,^[9] the convective cells began to show organization as they progressed eastward.

One such storm—which formed from the initial mid-afternoon activity near Arkadelphia, Arkansas—matured into a long-lived supercell as it progressed in an unstable, deeply moist, and highly sheared environment;^[10] this cell ultimately persisted for longer than 550 miles (890 km) over several hours from eastern Arkansas to northeastern Kentucky, producing two large and intense tornadoes along its track, among eleven tornadoes in total.

Tornado summary

Northeast Arkansas

This violent, long-tracked, and deadly EF4 wedge tornado was the fifth of eleven spawned by the Quad-State supercell, and the first of two violent tornadoes produced by the storm. It first touched down in Craighead County, Arkansas, just north of Bay, at 7:07 p.m. CST (01:07 UTC) on the evening of December 10, initially causing minor EF0 tree and outbuilding damage. As it moved through the south side of Bowman, it caused EF0 to EF1 damage as roofs were damaged, power poles and tree limbs were downed, and a radio antennae at a residence was bent. The tornado quickly intensified to EF2 strength as it crossed AR 18 and passed northwest of Lake City, downing trees and damaging or destroying some metal outbuildings. A house also sustained minor damage in this area. It grew to a width of 800 yards (730 m) as it crossed County Road 505 and tracked to the northeast, snapping power poles and unroofing a house along County Road 10. Another house sustained major roof damage in this area, an irrigation pivot sprinkler was overturned, and a silo was damaged. The tornado reached low-end EF3 strength as it moved through the western and northern fringes of Monette at 7:23 p.m. CST (01:23 UTC), resulting in significant damage. Two industrial buildings were destroyed at the west edge of town, and many trees and power poles were snapped. The Monette Manor nursing home was struck by the tornado, killing one person and trapping 20 other residents and employees. The building sustained major structural damage, losing much of its roof and sustaining collapse of some masonry exterior walls.^[11] Multiple homes and mobile homes were damaged or destroyed in a neighborhood near the nursing home, and several large grain silos were torn apart.^[12]^[13] In addition to the fatality, five people were seriously injured in Monette. AR 135 and AR 139 were also shut down near the town due to downed power lines on the roadways.^[14] Maximum wind speeds in the Monette area were estimated at 143 mph (230 km/h).

The tornado continued at low-end EF3 intensity as it crossed into northwestern Mississippi County, striking the northern part of Leachville at 7:30 p.m. CST (01:30 UTC). As the tornado crossed AR 77, it completely destroyed a local Dollar General store sweeping a portion of it off its foundation, killing the store's assistant manager. A few metal-framed warehouse buildings across AR 77 were badly damaged or destroyed, cars and semi-trailers were tossed, and multiple homes and mobile homes were damaged or destroyed in town. Extensive tree damage also occurred, and businesses in downtown Leachville had roofing blown off. Maximum wind speeds in the Leachville area were estimated at 145 mph (233 km/h). The tornado continued northeast for six miles (9.7 km) and grew larger as it passed near the rural community of Buckeye, and very intense tree damage was noted along West County Road 38. An entire row of large trees were completely debarked and denuded at this location, and an EF3 rating was applied. Power poles were snapped and an outbuilding was also destroyed by the tornado in this area.

Missouri Bootheel

As it crossed the state line into Dunklin County in the Missouri Bootheel at 7:40 p.m. CST (01:40 UTC), high-end EF2 damage occurred as multiple outbuildings, mobile homes, and houses were damaged or destroyed, and many power poles and trees were snapped, with some low-end debarking noted. It continued south of Hornersville and over the Hornersville Swamp Conservation Area, briefly weakening to EF1 intensity. Trees and power poles were damaged in this area, and a mobile home also sustained minor damage. Farther to the northeast, the damage became more severe again as multiple metal truss transmission towers were twisted or collapsed near County Road 722, and damage in this area was rated EF3. A house along the periphery of the circulation sustained minor damage, and some power poles were pushed over as well. High-end EF2 damage occurred as the tornado then crossed into Pemiscot County west of Steele. Trees were snapped and denuded, power poles were downed, a couple of homes were heavily damaged, and a pickup truck was tossed along this segment of the path.^[15] The tornado became weak again as it passed just south of Braggadocio at EF1 intensity, damaging or destroying some barns and outbuildings, and inflicting roof damage to homes. However, the tornado abruptly became violent as it moved through the intersection of State Highway J and County Highway 407 to the east of town, causing EF4 damage as two homes were swept from their foundations and scattered across fields. A nine-year-old girl was killed, and her parents and two younger sisters were injured in the destruction of one of the homes. As it crossed I-55 just south of Hayti, the large wedge tornado weakened back to EF2 strength and blew multiple semi-trailer trucks and a car off the highway into a field. Several semi-truck drivers were injured here, and the driver of the car was killed. In addition to the two fatalities, at least nine people overall were injured in the county.^[16]^[17]^[18]

Northwest Tennessee

East of Hayti, the tornado caused additional EF2 power pole damage and then crossed the Mississippi River into Lake County, Tennessee around 8:20 p.m. CST (02:20 UTC). It briefly crossed a bend in the river back into Missouri before crossing into Lake County again. Moving through central Lake County, the tornado narrowly missed the small community of Wynnburg, producing EF3 damage in rural areas outside of town, where numerous large trees were snapped and denuded, and some were debarked. Metal high-tension power poles were bent to the ground in this area as well. The tornado reached peak intensity a second time near Tiptonville as it moved across the southern shore of Reelfoot Lake, striking the Cypress Point Resort and causing three fatalities. A bait and tackle shop sustained EF4 damage as it was swept clean from its foundation, with only a bare concrete slab remaining. Multiple cottages, houses, and cabins were also destroyed, while a couple of two-story hotel buildings sustained total destruction of their top floors and collapse of many walls on their first floors, with damage to those structures rated EF3. A gift shop and a restaurant also sustained severe damage, large amounts of debris was scattered throughout the area, and several people sustained serious injuries at the resort. The tornado crossed the southeastern part of the lake, before moving ashore again as it entered Obion County, causing high-end EF2 damage as it damaged or destroyed cabins, outbuildings, and houses along Lake Drive. Continuing at high-end EF2 strength, the tornado narrowed as it impacted the small town of Samburg, resulting in major damage along SR 22. Houses in town had roofs and exterior walls ripped off, RV campers were tossed, and mobile homes were destroyed. The city hall building, post office, a gas station, and several other buildings were damaged or destroyed as well. One person was killed in town, and others were injured. Northeast of town, the tornado began to weaken, with the roof being blown off a farm building along Old Samburg Road. Trees and tree limbs were also downed, and damage was rated EF1 in this area. It continued northeastward along the road, causing EF0 tree limb damage until it dissipated approximately 2.5 miles (4.0 km) northeast of Samburg at 8:36 p.m. CST (02:36 UTC).^[19]^[20]

Aftermath

The tornado was rated as a low-end EF4 with winds estimated at 170 mph (270 km/h), reaching a peak width of 1,800 yards (1,600 m) along an 81.17-mile (130.63 km) path through portions of three states, remaining on the ground for 89 minutes. Eight fatalities occurred, along with many injuries, some of which were serious.^[21]^[22]^[23]^[24] After the tornado dissipated, the parent supercell entered a cycling phase, producing three brief tornadoes, one rated EF1 and the other two rated EF0, in Obion County northeast of Samburg and west of Union City. As the storm passed to the northwest of Union City, it produced a stronger, longer-tracked tornado near Woodland Mills.^[19]^[25]

From May 21 to May 26, 2011, one of the largest tornado outbreaks on record affected the Midwestern and Southern regions of the United States. A six-day tornado outbreak sequence, most of the tornadoes developed in a corridor from Lake Superior southwest to central Texas, while isolated tornadoes occurred in other areas. An especially destructive EF5 tornado destroyed one-third of Joplin, Missouri, resulting in 158 deaths and over 1,000 injuries. The Joplin tornado was the deadliest in the United States since April 9, 1947, when an intense tornado killed 181 in the Woodward, Oklahoma, area. Tornado-related deaths also occurred in Arkansas, Kansas, Minnesota, and Oklahoma. Overall, the tornado outbreak resulted in 186 deaths, 8 of those non-tornadic, making it second only to the 2011 Super Outbreak as the deadliest since 1974. It was the second costliest tornado outbreak in United States history behind that same April 2011 outbreak, with insured damage estimated at $4–7 billion.

The tornado outbreak of February 28 – March 1, 2017 was a widespread and significant outbreak of tornadoes and severe weather that affected the Midwestern United States at the end of February 2017 and beginning of March. Fueled by the combination of ample instability, strong wind shear, and rich low-level moisture, the event led to 71 confirmed tornadoes and thousands of other non-tornadic severe weather reports. The most notable aspect of the outbreak was a long-tracked EF4 tornado—the first violent tornado of 2017 and the first violent tornado during the month of February since the 2013 Hattiesburg, Mississippi tornado—that tracked from Perryville, Missouri to near Christopher, Illinois, killing one person. Three EF3 tornadoes were recorded during the event, including one that caused two fatalities in Ottawa, Illinois, one that caused a fatality near Crossville, and one that heavily damaged or destroyed homes in and around Washburn. In addition to the deaths, 38 people were injured by tornadoes and an additional 30 were injured by non-tornadic impacts, mainly by fallen trees.
