The 1974 Super Outbreak was the second-largest tornado outbreak on record for a single 24-hour period, just behind the 2011 Super Outbreak.
 It was also the most violent tornado outbreak ever recorded, with 30 F4/F5 tornadoes confirmed.
 From April 3 to April 4, 1974, there were 148 tornadoes confirmed in 13 U.S. states and the Canadian province of Ontario.
 In the United States, tornadoes struck Illinois, Indiana, Michigan, Ohio, Kentucky, Tennessee, Alabama, Mississippi, Georgia, North Carolina, Virginia, West Virginia, and New York.
 The entire outbreak caused more than $600 million (1974 USD) in damage in the United States alone, and extensively damaged approximately 900 mi2 along a total combined path length of 2,600 mi .
 At one point, as many as 15 separate tornadoes were ongoing at the same time.
The tornado outbreak sequence of May 21–26, 2011 was a deadly series of tornado activity across the Midwestern and Southern regions of the United States.
 It was one of the largest tornado outbreaks on record.
 Most of the tornadoes developed in a corridor from Lake Superior southwest to central Texas; isolated tornadoes occurred in other areas.
 An especially destructive tornado destroyed one-third of Joplin, Missouri, resulting in 162 deaths and 1000 injuries.
 The Joplin tornado is the deadliest in the US 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 184 deaths, 6 of those non-tornadic, making it second only to the 2011 Super Outbreak as the deadliest since 1974, and the second costliest tornado outbreak in US history behind that same April 2011 outbreak, with insured damage estimated at $4–7 billion.
The June 2010 Northern Plains tornado outbreak was one of the most prolific summer tornado outbreaks in the Northern Great Plains of the United States on record.
 The outbreak began on June 16 with a several tornadoes in South Dakota and Montana.
 The most intense storms took place the following day across much of eastern North Dakota and much of Minnesota and North Dakota.
 The system produced 93 tornadoes reported across four states while killing three people in Minnesota.
 Four of the tornadoes were rated as EF4 on the Enhanced Fujita scale, the most violent tornadoes in a 24-hour period since there were five within 15 hours on February 5–6, 2008.
 This was the region's first major tornado outbreak of the year and one of the largest on record in the region, comparable to a similar outbreak in June 1992.
 The 48 tornadoes that touched down in Minnesota on June 17 marked the most active single day in the state's history.
 June 17 was the second largest tornado day on record in the meteorological summer, behind the most prolific day of the 2003 South Dakota tornado outbreak on June 24, 2003.
The tornado outbreak of January 21–23, 2017 was a prolific and deadly winter tornado outbreak that occurred across the Southeast United States.
 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 EF3s 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 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 (2017 USD).
The tornado outbreak of April 14–16, 2011 was among the largest recorded tornado outbreaks in U.S. history, producing 178 confirmed tornadoes across 16 states and severe destruction on all three days of the outbreak.
 A total of 38 people were killed from tornadoes and an additional five people were killed as a result of straight-line winds associated with the storm system.
 The outbreak of severe weather and tornadoes led to 43 deaths in the Southern United States.
 This was the largest number of fatalities in an outbreak in the United States since the 2008 Super Tuesday tornado outbreak.
 However this outbreak was soon surpassed no less than two weeks later by the 2011 Super outbreak, which killed 324 people.
The November 1992 tornado outbreak was a three-day tornado outbreak that struck large parts of the Eastern United States and the Midwestern United States on November 21–23.
 Also sometimes referred to as the Widespread Outbreak (as was the 1974 Super Outbreak initially), this exceptionally long lasting and geographically large outbreak produced over $300 million in damage, along with 26 deaths and 641 injuries in Alabama, Georgia, Indiana, Kentucky, Maryland, Mississippi, North Carolina, Ohio, South Carolina, Tennessee, Texas, and Virginia.
 The outbreak, with 41 continual hours of tornado activity, was one of the longest-lasting and largest fall tornado outbreaks in the United States Published studies of this outbreak report widely varying numbers of confirmed tornadoes (92, 94, 146 and 143, with the higher numbers reflected in NOAA studies).
The February 1971 Mississippi Delta tornado outbreak struck portions of the Lower Mississippi River Valley and the Southeastern United States on February 21–22.
 The two-day tornado outbreak produced at least 19 tornadoes, and probably several more, mostly brief events in rural areas; killed 123 people across three states; and "virtually leveled" entire communities in the state of Mississippi.
 Three violent, long-lived tornadoes—two of which may have been tornado families—in western Mississippi and northeastern Louisiana caused most of the deaths along 300 mi of path.
 One of the tornadoes attained F5 intensity in Louisiana, the only such event on record in the state.
 The outbreak also generated strong tornadoes from Texas to Ohio and North Carolina.
 The entire outbreak is the second deadliest ever in February, behind only the Enigma tornado outbreak in 1884 and ahead of the 2008 Super Tuesday tornado outbreak.
 February 21 was the fourth-deadliest day for tornadoes in Mississippi on record.
 At one point, the National Weather Service WSR-57 radar in Jackson, Mississippi, reported four hook echoes, often indicative of tornado-producing supercells, simultaneously.
The Mid-June 1992 tornado outbreak was one of the largest tornado outbreaks on record, affecting portions of the Central United States from June 14 to June 18, 1992.
 The outbreak began on June 14 when six tornadoes touched down in Colorado and Idaho.
 Fifty-eight tornadoes were reported across portions of the Great Plains on June 15, and 65 more were reported over much of the central U.S. on June 16.
 The 123 tornadoes that touched down on June 15–16 make that two-day span the 5th largest two-day tornado outbreak in U.S. history behind the 1974 Super Outbreak, the May 2004 tornado outbreak sequence, the April 14–16, 2011 tornado outbreak, and the 2011 Super Outbreak.
 Twenty-eight more tornadoes touched down on June 17, and 13 more touched down on June 18, giving this outbreak 170 confirmed tornadoes.
The 2011 Super Outbreak was the largest, costliest, and one of the deadliest tornado outbreaks ever recorded, affecting the Southern, Midwestern, and Northeastern United States and leaving catastrophic destruction in its wake.
 The event affected Alabama and Mississippi the most severely, but it also produced destructive tornadoes in Arkansas, Georgia, Tennessee and Virginia, and affected many other areas throughout the Southern and Eastern United States.
 In total, 362 tornadoes were confirmed by NOAA's National Weather Service (NWS) and Government of Canada's Environment Canada in 21 states from Texas to New York to southern Canada.
 Widespread and destructive tornadoes occurred on each day of the outbreak, with April 27 being the most active day with a record of 218 tornadoes touching down that day from midnight to midnight CDT (0500 – 0500 UTC).
 Four of the tornadoes were destructive enough to be rated EF5, which is the highest ranking possible on the Enhanced Fujita scale; typically these tornadoes are only recorded about once each year or less.
The 1932 Deep South tornado outbreak was a deadly tornado outbreak that struck the Southern United States on March 21–22, 1932.
 At least 36 tornadoes—including 27 killers and several long-lived tornado families—struck the Deep South, killing more than 330 people and injuring 2,141.
 Tornadoes affected areas from Mississippi north to Illinois and east to South Carolina, but Alabama was hardest hit, with 268 fatalities; the outbreak is considered to be the deadliest ever in that U.S. state, and among the worst ever in the United States, trailing only the Tri-State Tornado outbreak in 1925, with 747 fatalities, and the Tupelo-Gainesville outbreak in 1936, with 454 fatalities.
 The 1932 outbreak produced 10 violent tornadoes, classified F4 or F5 on the Fujita scale of tornado intensity, eight of which occurred in Alabama alone, and is surpassed only by the March 1952 tornado outbreak, with 11 violent tornadoes; the 2011 Super Outbreak, with 15; the 1965 Palm Sunday tornado outbreak, with 17; and the 1974 Super Outbreak, with 30.
