An extended period of tornado activity occurred between April 20–27, 2007. The outbreak sequence is best known for producing a deadly tornado that struck the border cities of Piedras Negras, Coahuila, and Eagle Pass, Texas, along the United States-Mexican border on April 24, 2007, killing ten people. Other strong tornadoes also caused damage and injuries in or near the towns of Moorefield, Nebraska, Gothenburg, Nebraska, Cactus, Texas, and Tulia, Texas. In all, 91 tornadoes were confirmed causing 10 fatalities and injuring at least 270 others.
An unseasonably strong tornado outbreak began on January 7, 2008, and continued for nearly four days across the Central and Southern United States, with the hardest hit area being southwestern Missouri, northwestern Arkansas, and the surrounding area. In addition, a strong supercell in northern Illinois and southeastern Wisconsin produced that region's first January tornadoes since 1967.
A destructive and deadly tornado outbreak that took place across the Southern and Central United States from May 1 to May 3, 2008. The outbreak was responsible for at least seven fatalities and 23 injuries in Arkansas. There were at least 29 tornado reports from Iowa to Oklahoma on May 1 and 67 more in Arkansas, Missouri, Mississippi, Tennessee, Louisiana and Texas on May 2. A total of 60 tornadoes were confirmed by weather authorities.
The tornado outbreak of March 28–29, 2010 affected the Southeast United States and The Bahamas on March 28-29, 2010.
On March 2 and 3, 2012, a deadly tornado outbreak occurred over a large section of the Southern United States into the Ohio Valley region. The storms resulted in 41 tornado-related fatalities, 22 of which occurred in Kentucky. Tornado-related deaths also occurred in Alabama, Indiana, and Ohio. The outbreak was the second deadliest in early March for the U.S. since official records began in 1950; only the 1966 Candlestick Park tornado had a higher death toll for a tornadic system in early March.
On November 17, 2013, the deadliest and costliest November tornado outbreak in Illinois history took shape, becoming the fourth-largest for the state overall. With more than 30 tornadoes in Indiana, it was that state's largest tornado outbreak for the month of November, and the second largest outbreak recorded in Indiana. Associated with a strong trough in the upper levels of the atmosphere, the event resulted in 77 tornadoes tracking across regions of the Midwest United States and Ohio River Valley, impacting seven states. Severe weather during the tornado outbreak caused over 100 injuries and eleven fatalities, of which eight were tornado related. Two tornadoes—both in Illinois and rated EF4 on the Enhanced Fujita scale—were the strongest documented during the outbreak and combined for five deaths. In addition to tornadoes, the system associated with the outbreak produced sizeable hail peaking at 4.00 in (10.2 cm) in diameter in Bloomington, Illinois, as well as damaging winds estimated as strong as 100 mph (160 km/h) in three locations.
On December 23, 2015, an outbreak of supercell thunderstorms produced tornadoes across northern Mississippi and middle Tennessee, resulting in 13 tornado-related deaths and numerous injuries. Other tornadoes occurred as far north as Indiana and Michigan. Scattered tornado activity continued over the next two days before the outbreak ended. This was the first of two deadly tornado outbreaks to impact the southern United States during December 2015 with the other occurring just a day after this one ended.
An unusually prolific and very destructive late-winter tornado outbreak resulted in significant damage and numerous casualties across the southern and eastern half of the United States between February 23–24, 2016. Lasting over a day and a half, the outbreak produced a total of 61 tornadoes across eleven states, which ranked it as one of the largest February tornado outbreaks in the United States on record, with only the 2008 Super Tuesday tornado outbreak having recorded more. In addition, it was also one of the largest winter tornado outbreaks overall as well. The most significant and intense tornadoes of the event were four EF3 tornadoes that struck southeastern Louisiana, Pensacola, Florida, Evergreen, Virginia, and Tappahannock, Virginia. Tornadoes were also reported in other places like Texas, Florida, and Pennsylvania. Severe thunderstorms, hail and gusty winds were also felt in the Northeastern United States and Mid-Atlantic states on February 24 as well.
A prolific and deadly winter tornado outbreak struck areas across the Southeast United States between January 21–23, 2017. Lasting just under two days, the outbreak produced a total of 81 tornadoes, cementing its status as the second-largest January tornado outbreak and the third-largest winter tornado outbreak since 1950. Furthermore, it was the largest outbreak on record in Georgia with 42 tornadoes confirmed in the state. The most significant tornadoes were three EF3 tornadoes that heavily damaged or destroyed portions of Hattiesburg, Mississippi, and Albany and Adel, Georgia. A total of 20 people were killed by tornadoes—mainly during the pre-dawn hours of the outbreak—making it the second-deadliest outbreak in January since 1950, behind the 1969 Hazlehurst, Mississippi tornado outbreak that killed 32 people. In addition, the tornado death toll was higher than the entire previous year. In the aftermath of the outbreak, relief organizations assisted in clean-up and aid distribution. Total economic losses from the event reached at least $1.3 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 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.
A significant severe weather and tornado outbreak affected multiple regions of the Eastern United States in mid-April 2019. Over the course of 40 hours, 75 tornadoes touched down. The outbreak produced numerous strong tornadoes throughout portions of the Deep South, while additional significant tornadoes occurred as far north as Ohio, Pennsylvania, and Delaware. The most significant tornado of the event was a long-tracked, high-end EF3 tornado that struck Alto, Texas and killed two people. Numerous weak tornadoes were also confirmed, along with numerous reports of hail and damaging straight line winds.
A significant severe weather and tornado outbreak affected the Southern United States between December 16–17, 2019. Discrete supercells developed in the early morning on December 16 and moved northeast, spawning multiple strong, long-tracked tornadoes in cities such as Alexandria and in Laurel before congealing into an eastward-moving squall line. During the outbreak, the National Weather Service issued several PDS tornado warnings as well as a rare tornado emergency for Alexandria. In addition to this, the Storm Prediction Center issued six tornado watches for the outbreak. The event happened to take place on the same date of another outbreak in a similar area 19 years earlier.
A significant tornado outbreak sequence took place from March 24–28, 2021 in the Southern United States, just one week after another outbreak affected similar regions. There were 43 tornadoes confirmed across 11 states, with the bulk of activity primarily on March 25, which resulted in the Storm Prediction Center (SPC) issuing its second high-risk outlook for the month of March, as well as the second high-risk outlook for 2021. Several intense tornadoes touched down on that day, including ones that prompted the issuance of rare tornado emergencies near Hoover, Alabama, Brent and Centreville, Alabama, and in the Newnan, Georgia area. March 27 also saw widespread tornado activity mainly across East Texas, Southern Arkansas, Louisiana, and Western Tennessee with several strong tornadoes touching down. Scattered to widespread wind and hail damage occurred throughout the outbreak sequence, and repeated rounds of heavy rain caused widespread severe flash and river flooding across much of Tennessee.
A large tornado outbreak struck the Southern region of the United States on March 21–22, 2022, before transitioning to the Eastern United States on March 23. The outbreak started with numerous supercell thunderstorms and severe squall lines developing in central Texas and southern Oklahoma, prompting the issuance of numerous tornado warnings, including multiple PDS tornado warnings. An EF3 tornado caused considerable damage in Jacksboro, Texas while an EF2 tornado from the same storm caused a fatality in Sherwood Shores. Other strong tornadoes caused damage near College Station and in the Austin and Houston metropolitan areas. Severe and tornadic activity continued into the next day as the system moved eastward with numerous tornadoes reported in Mississippi and Alabama. On the evening of March 22, a supercell moved through the New Orleans metropolitan area, with an EF3 tornado producing severe damage in Arabi, resulting in one death and at least two injuries. Widespread flooding also accompanied the decaying squall line in Alabama. Tornadoes occurred on March 23 over the Eastern United States, associated with the same system, including EF2 tornadoes near Pickens, South Carolina, and Gladesboro, Virginia. In all, 85 tornadoes were confirmed.
From April 4–5, 2022, a mesoscale convective system and numerous discrete supercells produced a swath of severe weather and several tornadoes in the Southeastern United States, including several strong, long tracked tornadoes. An EF3 tornado damaged or destroyed several homes in Bonaire, Georgia while a large EF3 tornado prompted a tornado emergency for Allendale and Sycamore, South Carolina. A violent EF4 tornado in Black Creek, Georgia resulted in one fatality as it destroyed several neighborhoods, and another large EF3 tornado caused widespread heavy tree damage northeast of Ulmer, South Carolina. More severe storms occurred across a large portion of the Southeast ahead of a cold front on April 6–7, with more tornadoes reported in South and Central Georgia and further south into Florida, all of which were weak. Along with the one tornadic death, trees felled by straight-line winds killed one person each in Louisiana and Texas.
An early-season tornado outbreak impacted the Southeastern United States on January 12, 2023. The result of a mid-level trough moving through, moisture and the presence of a strong low-level jet aided in the development of numerous severe and tornadic thunderstorms. Early in the outbreak, a strong EF2 tornado caused considerable damage in Winston County, Alabama, while another EF2 tornado struck just south of Greensboro. A destructive high-end EF2 tornado struck Selma, causing widespread damage and two injuries. The same storm produced a long-lived EF3 tornado that moved through or near Old Kingston, Titus, Equality, and Lake Martin, resulting in seven fatalities and several injuries in Autauga County alone. Another EF2 tornado from the storm struck areas in or around Five Points and Standing Rock before crossing into Georgia. After the dissipation of that tornado, nine more tornadoes, five of which were strong, caused heavy damage across west-central Georgia, especially in LaGrange, Griffin, and Experiment, the second one of which was impacted by four tornadoes in the span of 10 minutes, including two that were rated EF2 and EF3 respectively. Another EF2 tornado from the storm caused major damage and another fatality in the Jackson Lake area as well; an indirect death from the tornado also occurred the following day. Elsewhere, other tornadoes caused damage in Sumter and Mobile counties in Alabama, as well as parts of Mississippi, Tennessee, Kentucky, Illinois, and the Carolinas. In all, 43 tornadoes were confirmed.
On March 24, 2023, a severe weather and tornado outbreak began across portions of the lower Mississippi River Valley in the United States. A slow-moving trough moved eastward across the United States and interacted with a moist and unstable airmass originating from the Gulf of Mexico, resulting in widespread heavy rainfall, severe thunderstorms, and significant tornadoes over a four-day period. A violent high-end EF4 tornado moved through the towns of Rolling Fork, Midnight, and Silver City in western Mississippi, causing catastrophic damage and many fatalities. Multiple tornado emergencies were issued for that tornado and two subsequent EF3 tornadoes from the same supercell that struck Winona and Amory.
