This page documents notable tornadoes and tornado outbreaks worldwide in 2021. Strong and destructive tornadoes form most frequently in the United States, Argentina, Brazil, Bangladesh, and Eastern India, but can occur almost anywhere under the right conditions. Tornadoes also develop occasionally in southern Canada during the Northern Hemisphere's summer and somewhat regularly at other times of the year across Europe, Asia, Argentina, Australia and New Zealand. Tornadic events are often accompanied by other forms of severe weather, including strong thunderstorms, strong winds, and hail. Worldwide, 150 tornado-related deaths were confirmed with 103 in the United States, 28 in China, six in the Czech Republic, four in Russia, three in Italy, two in India, and one each in Canada, New Zealand, Indonesia, and Turkey.

The year started well below average with the lowest amount of tornado reports through the first two months in the past 16 years and remained below-average for most of the year due to inactivity during April, June, September, and November.^[1][2] Despite this, several intense outbreaks occurred in March, May, July, August, and October. The year ended on a destructive note, however, as December was incredibly active, more than doubling the previous record, which pushed 2021 above average. Additionally, 2021 had the most tornado fatalities in the United States since 2011.^[3]

Following a period of inactivity, the Storm Prediction Center issued a slight risk for severe weather for a broad area in northwest Alabama, northeast Mississippi, and southern Tennessee on January 25. This included a 5% risk for tornadoes.^[31] Isolated to scattered severe weather occurred throughout the afternoon into the evening, including an EF0 tornado that caused some tree damage in Fayette County, Tennessee.^[32][33] Later that evening, an isolated severe storm developed in Central Mississippi near I-55. The storm then tracked northeastward into Alabama, approaching the northern Birmingham metro area by 10:20 p.m. (04:20 UTC), exhibiting consistent, but broad, rotation. At 10:40 p.m. (04:40 UTC), the storm unexpectedly produced an intense and destructive tornado that struck the suburbs of Fultondale and Center Point. Significant structural damage occurred in Fultondale, with numerous homes, vehicles, and businesses being severely damaged or destroyed. A Hampton Inn sustained major structural damage, and Fultondale High School was significantly damaged as well. Considerable damage to homes and trees was also noted farther to the northeast in Center Point along the 10.4-mile (16.7 km) long damage path, which was up to 900 yards (820 m) wide. The tornado, which was rated mid-range EF3 with maximum winds of up to 150 mph (240 km/h), killed one person and injured at least 30 others.^[34][35]

After no tornadic activity on January 26, two weak EF1 tornadoes touched down southwest of Tallahassee, Florida, the next day.^[36][37] The second of the two tornadoes caused damage to the Tallahassee International Airport and narrowly missed the National Weather Service NEXRAD radar site at the airport, although functionality of the radar was disabled for about an hour after the tornado struck the airport grounds due to communication issues. Several planes and structures were damaged, but no injuries were reported.^[38] The tornado continued east, causing additional sporadic tree and property damage before lifting after tracking for 21.4 miles (34.4 km). It was given a rating of low-end EF1 based on tree damage in the employee lot of the airport.^[39]

On February 15, the Storm Prediction Center issued an Enhanced risk for severe weather. Multiple tornadoes, two of which were strong and destructive, struck the states of Florida, Georgia, and North Carolina. One supercell produced a tornado family of three tornadoes in the Florida Panhandle and Southwestern Georgia, with the final one being a large, strong EF2 tornado that caused major damage to homes and injured five people just outside of Damascus, Georgia. Around midnight, a destructive high-end EF3 tornado heavily damaged or destroyed dozens of homes in the Ocean Ridge Plantation subdivision near Sunset Beach, North Carolina. A community garden center and two homes were leveled at that location, one of which was swept completely away. A large metal building, several vehicles and RVs, and many trees sustained significant damage as well. Three fatalities and 10 injuries occurred as a result of this tornado. It was the deadliest tornado in Southeastern North Carolina since an F3 tornado killed eight in Riegelwood in November 2006. A total of six tornadoes were confirmed.^[40][41][42]

On the morning of March 13, the Storm Prediction Center issued a moderate risk with severe weather outlook for the Texas Panhandle, including a 15% risk for strong tornadoes.^[43] Multiple tornadoes touched down across the Panhandle, mainly areas between Lubbock and Amarillo and points eastward.^{[44][45][46][47]} A large EF2 wedge tornado moved from southwest of Happy in Swisher County to east of Canyon in Randall County, toppling a cell tower, inflicting major roof damage to homes, and snapping trees and power poles. As the tornado dissipated, a new tornado, rated EF1, formed and moved into Armstrong County, passing over Palo Duro Canyon, where several RVs were tossed and a cabin had its roof blown off. A third tornado was spawned just northeast of the second one, also crossing from Randall County to Armstrong County and lifting near Washburn, just before crossing into Carson County. Another EF2 tornado caused minor damage in Clarendon before strengthening and causing major damage to power poles and a mobile home near the Greenbelt Lake Reservoir.^[48] Farther to the north, an EF2 tornado moved through a rural area near Ensign, Kansas, snapping power poles and causing damage to grain bins and pivot irrigation sprinklers, although no tornado warning was issued for the storm. Several other tornadoes touched down very briefly and received ratings of EFU because they did not cause any damage. A total of 21 tornadoes were confirmed.^[49]

Following isolated tornado activity on March 16, a rare high risk outlook was issued by the SPC for March 17 in Mississippi and Alabama, including a 45% risk area for tornadoes, the first of which since May 2019.^[50] Forecasters noted the potential for violent, long-tracked tornadoes to occur in the risk area, though this did not occur. However, a few strong tornadoes did touch down and cause significant damage, though none exceeded EF2 intensity. The first tornado of the day touched down west of Waynesboro, Mississippi, just after 12:00 p.m. CDT and caused EF2 damage to chicken houses and trees.^[51] Other strong EF2 tornadoes caused damage in and around Silas, Billingsley, and Burnsville, Alabama.^[51] More severe weather occurred on March 18 along the Atlantic coast from Florida to Southern Maryland, and a moderate risk was issued from Eastern Georgia to North Central North Carolina on March 17.^[52] The moderate risk was downgraded to enhanced on March 18 due to a lack of buoyancy in the atmosphere, but numerous strong to severe thunderstorms still tracked through the area during the afternoon.^[53][54] Several more tornadoes were confirmed before the storms moved offshore that evening. Overall, this outbreak produced 51 tornadoes and no fatalities.^[54]

After isolated tornado and widespread hail activity in Texas the previous day, March 25 brought another severe weather outbreak to the Deep South, where a high risk outlook was issued for the second time in eight days. This included a 30% risk for tornadoes, with the potential for multiple strong and long-tracked tornadoes noted in the outlook discussion.^[55] The first supercell of the day produced three low-end EF3 tornadoes in central Alabama with the second one prompting a tornado emergency—the first of three issued during the outbreak—in Shelby County, Alabama.^[56][57] That tornado damaged or destroyed many homes in the southern suburbs of Birmingham. The home of broadcast meteorologist James Spann was one of the residences damaged by this tornado.^[58][59][60] The third tornado destroyed a manufacturing facility and a church, and badly damaged or destroyed many homes in and around Ohatchee, Alabama, killing six people. A long-tracked EF3 wedge tornado also tracked over 80 miles (130 km) across five counties in central Alabama for 98 minutes, causing significant damage near Sawyerville, Greensboro and Brent while injuring 13. The most intense tornado of the event was a low-end EF4 tornado that caused major damage in Newnan, Georgia, during the overnight hours, leveling homes and resulting in one indirect death due to a heart attack.^[61]

An EF2 tornado ripped the roofs off several homes near Waynesboro, Tennessee, as well.^[62] Tornado activity on March 26 was limited to a high-end EF1 tornado that damaged a house and flipped a car near Middlebury, Vermont, injuring two people. However, the SPC issued an enhanced risk for parts of the Southern United States for March 27, including a 10% hatched risk area for tornadoes. More strong tornadoes were reported that evening, and several PDS tornado warnings were issued in Texas, Arkansas, and Tennessee. One person was killed by an EF2 tornado that badly damaged or destroyed multiple homes near Carthage, Texas. An EF2 tornado also severely damaged a rice mill near De Witt, Arkansas, and another EF2 tornado struck the north edge of Monticello, tossing multiple vehicles and damaging a construction company. A final EF1 tornado that destroyed outbuildings and downed trees was confirmed near Fairview, Alabama, on the morning March 28 before a squall line produced widespread wind damage in the Delaware Valley that afternoon. The severe weather ended that night as the storms moved offshore into the Atlantic Ocean. Overall, 43 tornadoes were confirmed throughout the outbreak sequence, which led to seven fatalities, plus one indirect and numerous injuries.^[63]

Several rounds of intense severe thunderstorms brought significant damaging winds, very large hail, and several tornadoes primarily across the Southern United States from April 9 into the evening of April 11.^[68] April 9 started with several clusters of multi-cells, supercells, and bowing segments across much of the Deep South. Strong straight-line thunderstorm winds in Shreveport, Louisiana, toppled a tree onto a mobile home around 6:30 p.m. (23:30 UTC), resulting in a fatality.^[69] Several large hail-producing supercells then formed and moved through areas from Oklahoma to North Texas before merging into a large squall line and surging southeastward into Arkansas and Louisiana, producing widespread wind damage. Meanwhile, several tornado-producing supercells formed ahead of the line. A weak EF0 tornado was recorded by several storm spotters near Pelahatchie, Mississippi, causing intermittent tree damage. Just after midnight on April 10, a large EF1 tornado ripped roofs off of sheds and carports and knocked down trees, including some that fell on homes, near Columbia, Mississippi. To the southwest, a low-end EF3 tornado tossed vehicles and damaged or destroyed several homes and mobile homes in the rural community of Waxia near Palmetto, Louisiana, just after 2:00 a.m. CDT (07:00 UTC), resulting in one fatality and seven injuries.^[70][71] Later that morning, the squall line produced multiple tornadoes in the Florida Panhandle. A strong tornadic waterspout came onshore in Laguna Beach, Florida, causing severe EF2 damage to a business and damaging several homes. Another tornadic waterspout struck Gulf Lagoon Beach, located at the southeastern edge of the Panama City Beach city limits and caused EF0 damage to beach furniture. In Lynn Haven, an EF1 tornado caused considerable damage to an automotive business.^[72][73] That afternoon, isolated to widely scattered severe storms formed from the Great Lakes to the Carolinas, producing sporadic wind and hail damage as well as isolated tornadoes into the overnight hours. An EF1 tornado also caused damage to businesses and a radio tower, and flipped a car near Seneca, South Carolina.^[73] A brief EF0 tornado damaged a few homes near Cutlerville, Michigan, and another EF0 tornado damaged a home near Reidville, South Carolina.^[74][75] Early on April 11, another EF1 tornado caused damage to homes and outbuildings near Belvoir, North Carolina.^[76] That afternoon, another squall line pushed southeastward down the entire Florida panhandle, producing mainly wind and hail damage, although a brief EF0 tornado that caused minor tree damage was confirmed near Eagle Lake.^[77] Another non-tornadic fatality occurred near Spring Hill when a person got out of their car after it was struck by a fallen tree and was electrocuted when they came in contact with downed power lines.^[78] Overall, the outbreak generated 20 tornadoes, resulting in one fatality. Two other non-tornadic deaths also occurred as a result of the severe weather. There was also at least $635 million in damage.^[67]

On July 14, an outbreak of mostly weak tornadoes struck the state of Iowa, with at least 26 tornadoes being confirmed in the state.^[63][128] A tornado watch was issued for northern Iowa at 2:35 pm CDT, and numerous tornadic supercells moved through central and eastern portions of the state. The most significant tornado of the outbreak was a large multiple-vortex EF3 tornado that destroyed a farmstead near Lake City, Iowa, and caused damage to a bus shed, trees, power lines, and the roofs of homes in the town itself. An EF2 tornado caused substantial damage to trees, power lines, and farm buildings near Waverly.^[82] An EF1 tornado destroyed outbuildings and inflicted roof damage to homes in the town of Dysart, and other EF1 tornadoes caused minor to moderate damage to crops and farms as they passed near Readlyn, Shell Rock, and Stanhope, Iowa.^[82] An EF0 tornado caused tree, roof, and siding damage in Oelwein as well.^[129] The next day, the weather system moved northeastward into Canada and produced six EF2 tornadoes and one EF1 tornado in Ontario, along with one EF1 tornado in Quebec. The most significant tornado of the day was a high-end EF2 tornado that impacted Barrie, where significant damage to many homes occurred in residential areas of town. Multiple homes had their roofs torn off, and a few sustained some loss of their second floor exterior walls. Trees were downed and cars were flipped by the tornado as well. A total of 71 homes were left uninhabitable due to the tornado. Ten people were injured in Barrie, a few seriously. An EF1 tornado was confirmed between Chalk River and Petawawa, causing tree damage along its path, while another EF1 tornado was confirmed near Sheenboro, Quebec.^[130] A strong EF2 tornado injured one person and severely damaged a brick farmhouse near Little Britain, which had its roof ripped off and also sustained some collapse of its upper exterior walls. Near Lorneville, another EF2 tornado carved a 13 km long damage path, downing trees and destroying barns and farm outbuildings. Two EF2 tornadoes also tracked through remote areas near Dwight and Lake Traverse, snapping and uprooting numerous trees.^[131] The sixth EF2 tornado was confirmed near Sunbeam Lake in Algonquin Provincial Park, downing a swath of trees and injuring two campers.^[132] A total of 32 tornadoes were confirmed as a result of this outbreak, which caused 13 injuries.^[133][134] The tornadoes in Canada caused $100 million in damage.^[135] Meanwhile, the tornadoes in Iowa caused $4.183 million in damage.^[136]

A significant severe weather and tornado outbreak severely impacted portions of the Northern United States in late July 2021. On July 28, the SPC issued moderate risk of severe weather for parts of the Great Lakes region, highlighting the potential for a major damaging straight-line wind event. A secondary threat for embedded tornadoes was also present, and a 10% risk area for tornadoes was outlined. An intense linear mesoscale convective system formed during the overnight hours of July 28 into the early morning hours of July 29, producing widespread damaging winds across Wisconsin before moving south into northern Illinois and Indiana. Countless trees and power lines were downed, structures were damaged, and more than 130,000 homes and businesses were without power in Wisconsin and Illinois following the passage of the damaging line of storms. A motorist near Ripon, Wisconsin, was killed after crashing into a fallen tree and power line. The severe weather forced a nighttime airshow at the Experimental Aircraft Association's EAA AirVenture Oshkosh to be postponed until Thursday, and most activities at the event shut down earlier than planned on Wednesday.^[137] 14 weak tornadoes embedded within the line of storms touched down in Wisconsin overnight, causing extensive tree and roof damage along their paths. Two of these tornadoes caused EF1 damage in the Madison suburbs of West Middleton and Verona. An EF1 tornado also caused considerable damage to homes, trees, and power poles in and around the small community of Concord. Two other EF1 tornadoes occurred near Dousman, where docks and boats were damaged at a small lake, and trees and homes were damaged as well.^[138][139] Later on July 29, 2021, the SPC issued an enhanced risk for portions of the Mid Atlantic with a slight risk extending back through the Ohio Valley. This included a 5% risk of tornadoes, as a moderately sheared but extremely moist and unstable airmass was in place across the region. Multiple tornadic supercells formed in the Ohio Valley during the afternoon, and spread eastward across the Mid-Atlantic later that evening, producing numerous tornadoes. Some of the tornadoes were strong and damaging, including an EF2 tornado that caused heavy damage to homes, outbuildings, power poles, and trees in New Athens, Ohio. Another EF2 tornado destroyed a metal shed, caused major tree damage, and completely deforested a wooded hillside near Salineville. In Wintersville, an EF1 tornado damaged a church, one business, and 23 homes.^[140] An EF2 tornado snapped and uprooted many large hardwood trees, and triggered a PDS tornado warning as it tracked from near New Hope, Pennsylvania, to Titusville, New Jersey. In the Philadelphia suburbs, a destructive low-end EF3 tornado struck Trevose and Bensalem, Pennsylvania, causing major damage to multiple car dealership buildings and a mobile home park, flipping cars, and injuring five people. An anticyclonic EF0 tornado also briefly touched down in the Philadelphia neighborhood of Bustleton, causing minor damage to trees, an apartment building, and a few other structures.^[141][142] A damaging EF2 tornado moved through High Bar Harbor, New Jersey, later that night, tearing the roofs off of multiple homes, tossing boats and a boat trailer, snapping many trees and power poles, and causing eight minor injuries.^[142] Many other weak tornadoes were confirmed in Illinois, Indiana, Ohio, Pennsylvania, New Jersey and Maryland. Overall, 46 tornadoes were confirmed as a result of this outbreak.^[140]

During the early evening hours of August 7, an isolated supercell thunderstorm produced a tornado that touched down and moved through the southern edge of Boscobel, Wisconsin, causing minor to moderate roof and tree damage in town. The tornado strengthened and widened significantly as it moved east of town, reaching high-end EF3 intensity and damaging or destroying multiple homes, barns, and outbuildings. Power poles were snapped, and many trees were snapped and denuded by the tornado. After the tornado dissipated, the same parent supercell spawned an EF1 tornado that caused damage to trees and two barns near Highland.^[143][82]

An outbreak of weak tornadoes, associated with Tropical Storm Fred, impacted the Eastern United States.^[146][147] Eight tornadoes struck Georgia and thirteen struck the Carolinas on August 17, causing mostly minor property damage. An EF1 tornado caused shingle and tree damage in Americus, Georgia, while trees were downed and homes sustained roof and siding damage from another EF1 tornado in Mauldin, South Carolina. Homes were severely damaged by falling trees and outbuildings were destroyed by two EF1 tornadoes that passed near Carey and Danielsville, Georgia, as well.^[82][148] Eight more weak tornadoes touched down in Pennsylvania and New Jersey on August 18 and in the early morning hours of August 19. This included an EF1 tornado that downed many trees, some of which landed on cars, and damaged the roof of a house in Tilden Township, Pennsylvania. An EF0 tornado also caused minor roof damage in Valley View.^{[149][150][151][152]} Later on August 19, a few more EF0 tornadoes touched down in Connecticut and Massachusetts before the outbreak came to and end. A total of 31 tornadoes were confirmed.^[153]

A tornado outbreak occurred from Mississippi to Massachusetts due to Hurricane Ida. It started in the Southeastern United States as numerous weak tornadoes touched down between August 29–31. On August 30, an EF1 tornado in Saraland, Alabama, caused considerable damage to two hotels and an industrial building, injuring two people.^[155] The most significant day of the outbreak was September 1, as 10 tornadoes struck the Northeastern United States, a few of which were strong. New Jersey, Maryland, and Eastern Pennsylvania were particularly hard-hit, a region that had sustained significant damage from another outbreak that occurred just over a month prior. An EF2 tornado caused severe damage in Annapolis, Maryland, where homes and businesses had their roofs torn off and many trees and power lines were downed. Another EF2 tornado moved through a residential neighborhood in Oxford, Pennsylvania, causing extensive damage to homes.^[82][156] One person was killed and at least five others were injured due to a strong rain-wrapped EF2 tornado that moved through the Philadelphia suburbs of Fort Washington, Upper Dublin, and Maple Glen, flipping vehicles and leaving a path of significant damage to trees and structures. The strongest and most destructive tornado of the outbreak was a large EF3 tornado that struck Mullica Hill, New Jersey, destroying multiple homes and a large dairy farm. The same storm later dropped an EF1 tornado that prompted a tornado emergency for Burlington, New Jersey, and Croydon, and Bristol, Pennsylvania, the first of its kind in the Northeast, as well as the first such alert associated with a tropical cyclone.^[157] On September 2, a final weak EF0 tornado caused minor damage in Dennis, Massachusetts, before the outbreak came to an end.^[156] A total of 35 tornadoes were confirmed as a result of this outbreak, causing one fatality and 7 injuries.^[82]

A few tornadoes, two of which were strong, impacted parts of Ontario in early September. On September 6, at 4:05 am EST (08:05 UTC), an EF0 tornado hit Port Albert, damaging trees. The next day, two large EF2 tornadoes caused considerable damage in Southern Ontario. The first, and most significant, was a large, multiple-vortex EF2 wedge tornado that occurred near Lucknow, and grew to a peak width of 1.3 kilometres (1,400 yd) wide. This strong rain-wrapped tornado was spawned by a large high-precipitation supercell thunderstorm, and first developed over Lake Huron before moving ashore, causing extensive tree and structural damage from Kingsbridge to south of Lucknow. Many large trees were downed along the path, and outbuildings were destroyed, with sheet metal debris from the structures scattered across fields. A second EF2 tornado was confirmed near Kenilworth. It grew to a width of 1.2 kilometres (1,300 yd) wide as it impacted a farm, took the top off of a silo, and caused severe tree damage. The last two tornadoes of the day were both given an EF0 rating, and they occurred near Goderich and in the city of Vaughan, causing tree damage. A total of five tornadoes were confirmed. In addition to these tornadoes, straight-line winds from downbursts caused considerable damage in several other communities in Ontario as well.^[158]

A long-lasting outbreak of mainly weak tornadoes affected the Great Plains and Midwest beginning on October 9, when a few weak tornadoes touched down in North Dakota and Minnesota. During the early morning hours of October 10, an EF2 tornado snapped and uprooted numerous trees as it moved through heavily forested areas of Cook County, Minnesota, before crossing the border into Canada, causing additional tree damage at EF1 intensity near Mountain Lake. Also in Canada, an EF2 tornado caused significant tree damage near Dryden, Ontario.^[159] Later that day, a shortwave trough moved over the Great Plains, prompting the Storm Prediction Center to issue a moderate risk for portions of Oklahoma and northeastern Texas.^[160] 13 tornadoes touched down in Oklahoma that evening, most of which were weak. However, one EF2 tornado caused considerable damage in Anadarko, where several structures were damaged, and a few were destroyed. Another tornado caused EF1 damage to homes, businesses, and a school building in Coweta. The towns of Warwick and Johnson sustained minor damage from EF0 tornadoes. In addition to the tornadoes, a destructive hailstorm moved through the Oklahoma City metropolitan area just 5.5 months after another hailstorm damaged the southern part of the same area.^{[82][161][162][163]} More tornadoes developed on October 11, most of them in Illinois, including an EF2 tornado that destroyed a couple of large outbuilding structures in Wrights.^{[82][164][165]} Another round of tornadoes struck Oklahoma and Kansas on October 12, continuing into the early morning hours of October 13. Some of these tornadoes were large and may have been strong, but remained in remote areas. An EF1 tornado tracked from Mustang to the southeast side of Oklahoma City, damaging homes, trees, and vehicles. Another EF1 tornado caused tree damage near downtown Oklahoma City.^{[82][162][166]} Two more EF1 tornadoes touched down in Traverse County, Minnesota, later that day, causing damage to trees and farm outbuildings.^[167] Overall, 68 tornadoes were confirmed as a result of this outbreak.^[82]

In mid-October, a small outbreak produced several tornadoes in Arkansas, Indiana, Ohio, Pennsylvania, and Quebec, most of them weak.^[168][169] The outbreak first produced a few weak tornadoes on October 15, including an EF0 tornado that caused minor damage in Lexington, Indiana. More tornadoes touched down on October 16, a majority of which were spawned by a very long-tracked cyclical supercell that formed in southwestern Indiana, and dissipated in western Pennsylvania. A brief but damaging EF2 tornado caused heavy damage in New Salem, Ohio. A well-built outbuilding structure was destroyed, many trees and power lines were downed, a house sustained roof and exterior wall loss, other structures had roof damage, and debris was scattered throughout the small town.^[170] A secondary EF0 tornado also touched down outside of town, damaging outbuildings, blowing the roof off of a manufactured home, and injuring one person.^[171] An EF0 tornado also downed trees and damaged a pavilion in the town of Shippingport, Pennsylvania. Farther to the north in Quebec, three EF0 tornadoes near Sainte-Séraphine, Melbourne, and Cowansville caused minor tree and structural damage. The weather system also brought forth a cold front, ending a warm spell in the Northeast, as temperatures dropped by around 20 °F (11 °C).^[172] This allowed New York City to get below 50 °F (10 °C) for the first time since late May on October 18, the second latest on record. Altogether, 20 tornadoes were confirmed.^[82][173]

For the second time in a week, a small outbreak of mostly weak tornadoes impacted the Ohio Valley region. In Ohio, an EF1 tornado damaged several homes in Wickliffe, including one that sustained considerable damage. A high-end EF1 tornado also moved through Jackson Township, heavily damaging a large garage, recreational buildings, trees, and some businesses. Another EF1 tornado struck Mecca, causing damage to some homes in a subdivision. The strongest tornado of the outbreak produced EF2 damage as it tracked through Buffalo Township in Washington County, Pennsylvania, and dissipated near Houston. The tornado ripped the roofs off of two homes, one of which sustained partial collapse of some exterior walls. Other homes were also damaged, barns and outbuildings were destroyed, and many trees were snapped or uprooted along the path.^[174][175] A total of 19 tornadoes were confirmed.^[82]

Ahead of an advancing cold front, several supercells developed within an enhanced risk area for severe thunderstorms across central and southeast Missouri and southern Illinois,^[176] producing several tornadoes during the afternoon and evening hours.^[177] Just before 5:00 pm CDT, an EF2 tornado passed near the town of Purdin, Missouri, ripping the roof off of a house, destroying an office trailer at a propane company, destroying outbuildings, and snapping or uprooting numerous large trees. Later that night, a long-tracked EF3 tornado touched down and severely damaged or destroyed several homes near Farmington, before striking the town of St. Mary, where several more homes sustained significant damage, a large antique mall had its roof ripped off, and vehicles were flipped.^[178] A tornado emergency was issued for the town of Chester, Illinois, before the tornado crossed the Mississippi River into Illinois and struck the town, where many trees were downed and homes, businesses, and a nursing home were damaged. The tornado also caused minor to moderate damage in the small community of Bremen before dissipating.^[179] Farther to the south, another strong and destructive EF3 tornado moved through the northwestern fringes of Fredericktown, destroying multiple homes and businesses in the area. The tornado caused additional damage to trees, homes, and businesses in Junction City as well.^[82] Several other weak tornadoes occurred across the region that evening as well, including two EF0 tornadoes that touched down in the Sedalia, Missouri, area, one of which caused minor damage to trees and houses along the eastern outskirts of town. An EF1 tornado damaged a school building in Zalma, and another EF1 tornado blew the roof off of a house, damaged a barn, and downed trees near Camden as well. A lower-end severe weather threat occurred farther east the next day, with an EF1 tornado touching down and causing tree damage near Turbeville, Virginia. A total of 18 tornadoes were confirmed, resulting in at least two injuries.^[82] Damage was at least $160 million.^[180]

Late on October 26 and just after midnight on October 27, scattered severe thunderstorms and couple of isolated weak tornadoes occurred in the Great Plains region. An EF1 tornado caused minor damage in the Norman, Oklahoma, area, and an EF0 tornado caused damage to tree tops and roof panels in Turon, Kansas. To the south of this area, a strong cold front produced a strong to severe line of thunderstorms that moved into Eastern Texas. Later that morning, a supercell ahead of the squall line produced an EF2 tornado northwest of Pinehurst, which crossed Interstate 10, heavily damaging a home and several garages at a Texas Department of Transportation maintenance facility. An RV camper was tossed, and an ATV was lofted and thrown across Interstate 10 by the tornado. The same storm produced a second EF2 tornado southeast of Mauriceville and continued northeast to near Deweyville, critically injuring one person when it flipped a mobile home near the beginning of the path. Other mobile homes were damaged or destroyed, and several site built homes had their roofs torn off.^[181] An EF0 tornado also moved through the Port Acres neighborhood in Port Arthur, causing minor damage. Later, a brief but strong EF2 tornado embedded within the squall line also caused major structural damage to homes southern Lake Charles, Louisiana, while an EF1 tornado caused additional damage to warehouse buildings on the east side of the city.^[182][183] In Mandeville, a brief EF0 tornado caused minor tree and roof damage. During the evening of October 27, a high-end EF1 tornado caused considerable damage in Picayune, Mississippi, where some mobile homes were damaged or destroyed, extensive tree damage occurred, and homes had roofing and carports torn off. In Moss Point, another EF1 tornado killed one person when it struck a car traveling along MS 63, causing the driver to lose control and be ejected from the vehicle. Trees, structures, and other vehicles were also damaged in Moss Point. Overall, this small outbreak produced 17 tornadoes, resulting in one fatality and at least three injuries, one critical.^[184] Damage amounted to ten million dollars.^[185]

An EF0 tornado moved through parts of Vancouver, British Columbia; an area where tornadoes are extremely rare. The tornado struck part of the University of British Columbia campus and a nearby neighborhood, downing power lines, trees, and tree branches. Roads were blocked by debris, vehicles were damaged by falling trees, and power outages occurred.^[186]

The deadliest December tornado outbreak in United States history caused catastrophic damage and numerous fatalities, as multiple strong to violent long-tracked tornadoes devastated portions of the Southern United States and Ohio Valley from the evening of December 10, into the early morning hours of December 11. The event came to fruition as a trough progressed eastward across the United States, interacting with an unseasonably moist, unstable, and highly sheared environment across the Mississippi Valley. The SPC had issued a moderate risk of severe weather prior to the outbreak, including a 15% hatched risk area for tornadoes. Multiple supercell thunderstorms developed, and tornadic activity began later that evening in northeastern Arkansas, before progressing into Missouri, Illinois, Tennessee, and Kentucky. A high-end EF3 tornado damaged or destroyed multiple homes near Defiance, Missouri, killing one person and injuring two others. An EF3 tornado also destroyed an Amazon warehouse in Edwardsville, Illinois, killing six employees. Several other strong EF2 tornadoes touched down in more rural areas of Illinois with one of them tearing the roof off of a house, flipping tanker trucks, and destroying buildings at an agricultural services plant near Gays. Farther south, another EF2 tornado destroyed homes, mobile homes, and a vacant grocery story building in Trumann, Arkansas, and damaged the town's fire department building.^[82]

The most significant tornadoes of the outbreak were spawned by a long-tracked supercell thunderstorm that produced a violent tornado family across four states.^[197] Initially, media reports suggested that the tornado family, which was inaccurately identified by some media outlets as the "Quad-State tornado" due to the storm's similar characteristics to the Tri-State tornado, may have actually been a single, extremely long-tracked tornado that cut a path of destruction of up to 250 miles (400 km) from near Bay, Arkansas, to Rough River Lake in Kentucky.^[198] However, a path break in Obion County, Tennessee, confirmed two separate EF4 tornadoes, one tracking 81.2 miles (130.7 km) and the other tracking 165.7 miles (266.7 km). The first of these tornadoes first caused major damage in the Arkansas towns of Monette and Leachville, as many homes and businesses were destroyed in both towns. The tornado crossed into the Missouri Bootheel, where homes were swept completely away near Braggadocio, and semi-trucks were thrown from roadways near Hayti before it crossed the Mississippi River into Tennessee. There, many other structures were completely destroyed at a resort along the shores of Reelfoot Lake, and in Samburg. A total of eight people were killed by this first tornado, and 16 others were injured. The second violent tornado, which was rated high-end EF4, caused catastrophic damage and 57 fatalities as it tore through the towns of Cayce, Mayfield, Princeton, Dawson Springs, and Bremen. Thousands of homes and businesses were destroyed along the path, many of which were leveled or swept from their foundations. Trees were debarked, vehicles were thrown and mangled, severe ground scouring occurred, and 24 people were killed in Mayfield and surrounding Graves County alone. Mayfield sustained near-total destruction of its historic downtown square, and nine of the fatalities occurred at a candle factory that was flattened in the southwest part of town.^{[82][199][200]}

The city of Bowling Green, Kentucky, sustained major damage as it was struck by a high-end EF3 tornado during the very early morning hours of December 11, which destroyed numerous homes, and inflicted severe structural damage to townhouses and apartment buildings as it moved through multiple neighborhoods. Many businesses also sustained severe damage or were destroyed, including the GM Corvette Assembly Plant, which had much of its roofing torn off. The main Bowling Green tornado was accompanied by an EF2 satellite tornado that caused additional significant damage in the city. The supercell that produced the two Bowling Green tornadoes also produced an EF3 tornado that destroyed a dairy farm, homes and mobile homes, chicken houses, and a metal truss tower near Russellville. Another long-tracked, high-end EF3 tornado caused severe damage to homes in Kenton, Tennessee, before destroying many homes and businesses in Dresden, where major structural damage occurred in the downtown area. It continued past Dresden and eventually crossed into Kentucky, where additional significant damage occurred in the town of Pembroke before the tornado dissipated, resulting in 34 injuries but no fatalities along its path. Yet another EF3 tornado destroyed houses, tossed vehicles, killed one person, and injured 31 others near Saloma, Kentucky, while an EF2 tornado heavily damaged hotels, restaurants, and a trailer park in Cave City. Overall, this outbreak produced a total of 71 tornadoes, resulting in 89 fatalities and over 650 injuries.^{[82][201][202]}

A large and powerful low-pressure system that had previously produced heavy rain and snow to the Western United States the previous two days rapidly deepened and contributed to a historic expanse of inclement weather on December 15. On the west side of the system, a destructive wind storm impacted Colorado and Kansas. In Colorado, a 107 mph (172 km/h) wind gust was recorded in Lamar with widespread power outages and damage to homes recorded elsewhere. In Kansas, the intense winds led to substantial amounts of dust being stirred up. The massive dust storms closed several highways and led to numerous crashes along Interstate 70, including two crashes that resulted in three fatalities. The wind storms also contributed to an outbreak of wildfires in the drought-stricken north-central part of the state with 163,755 acres (66,269 ha) of land being burned across the region.^[203] The wildfires burned numerous buildings and killed hundreds of livestock. Two men were killed as a result of being burned and three other people were hospitalized due to their injuries. (These casualties were labeled as indirect.)^[204][205]

On the warm side of the system, an intense derecho struck areas of the Midwest, including Kansas, Nebraska, Iowa, Wisconsin, and Minnesota. In Russell, Kansas, wind gusts measured at 100 mph (160 km/h) blew roofs off homes and uprooted trees while Lincoln Airport in Lincoln, Nebraska, measured peak winds of 93 mph (150 km/h). At least 57 hurricane-force wind reports were received by the National Weather Service, signaling the most prolific wind event in the United States dating back to at least 2004.^[206] A semi-truck on US 151 near Walford, Iowa, was blown over, ejecting and fatally injuring the driver who was not wearing a seatbelt.^[206][207] The derecho was also a prolific tornado producer with dozens of tornado touchdowns being confirmed in Nebraska, Iowa, Minnesota, and Wisconsin, including several strong tornadoes in the Omaha metropolitan area and across Guthrie, Greene, and Webster counties in Iowa. Although none of the tornadoes exceeded EF2 intensity, 33 of the tornadoes were given this rating, which was 10 more than the amount of EF2+ tornadoes that occurred in the outbreak a few days prior. One EF2 tornado struck Columbus, Nebraska, causing minor to heavy damage to homes, snapping power lines, and damaging trees. It was the only tornado of the event to cause casualties as two people were injured.^[208] The tornado outbreak set a new record for the most tornadoes to hit Iowa in a single day with 61, far exceeding the previous record of 35 tornadoes set on August 31, 2014. Additionally, 21 of the tornadoes in Iowa were rated EF2 which beat the previous record of 16 EF2/F2 or greater tornadoes set on June 7, 1984. Prior to this event, there had only been five December tornadoes in Iowa, all in southeast Iowa.^[209] This outbreak also marked the first time that tornadoes were recorded in Minnesota in the month of December.^[210] Additionally, it was the first time since record keeping began in 1986 that the National Weather Service Forecast Office in Sioux Falls, South Dakota, had to issue both severe thunderstorm and tornado warnings during the month of December, with 6 and 8 issued, respectively. All of the severe storms took place in their coverage area in northwest Iowa.^[211] Total damage from the tornado outbreak amounted to at least $16.6 million in damage.^[212] Although the tornadoes were not as intense as the ones produced by the outbreak a few days prior, this event produced the most total confirmed tornadoes ever recorded in a December outbreak, with 120 in total. Ultimately, this became one of the largest single-day tornado outbreaks–in terms of number of confirmed tornadoes–in recorded history.^[213] Temperatures behind the derecho also dropped tremendously across the region, leading to light snow that was accompanied by strong winds. This triggered the first issuance of snow squall warnings by the National Weather Service Forecast Office in Hastings, Nebraska. As a whole, the event caused seven total deaths and at least $1.8 billion in damage.^[214]
