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.
A significant early season tornadic event affected portions of the Midwestern and Southern United States at the end of January 2013. The first signs of the outbreak came on January 23 as the Storm Prediction Center (SPC) detailed the eastward progression of a shortwave trough into an increasingly unstable air mass across portions of the lower Mississippi Valley; however, considerable uncertainty in the placement of severe thunderstorms caused the SPC to remove their threat outline. Succeeding many changes in the forecast, a Day 1 Moderate risk was issued for January 29, warning of the potential for widespread/significant damaging winds and a few strong tornadoes. The threat shifted eastward on January 30, encompassing a large section of the Southeastern United States. By late that day, the shortwave trough tracked northeastward into New England, ending the severe weather threat.
The Tornado outbreak of November 16–18, 2015 was a highly unusual nocturnal late-season tornado outbreak that significantly impacted the lower Great Plains on November 16 before producing additional weaker tornadoes across parts of the Southern United States the following two days. The first day of the outbreak spawned multiple strong, long-track tornadoes, including two consecutive EF3s that caused major damage near Pampa, Texas. Overall, the outbreak produced 61 tornadoes in all, and was described as by the National Weather Service office in Dodge City, Kansas as being "unprecedented in recorded history for southwest Kansas" given the magnitude and the late season. In addition, the tornado outbreak brought the first November tornadoes into northwest Kansas, and the first strong tornadoes in the Texas Panhandle in November, as well as the further west any F3/EF3 tornadoes touched down this late in the calendar year. Despite spawning multiple strong tornadoes after dark, no fatalities and only one minor injury occurred as a result of the outbreak.
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.
The December 2015 North American storm complex, also known as Winter Storm Goliath, was a major storm complex that produced a tornado outbreak, a winter storm, a blizzard and an ice storm in areas ranging from the Southwestern United States to New England. Tornadoes struck the Dallas–Fort Worth metroplex in Texas while several other states, especially Missouri, were affected by heavy rain and snow causing severe floods. As the system moved through the Great Lakes, heavy rain, ice pellets and heavy snow fell in the entire region. Wintry mix moved through southern Ontario and Quebec had significant snowfall on December 29. Almost 60 people were killed during the storm system's progression and aftermath, making it one of the deadliest such systems of 2015 in the United States.
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 deadly tornado outbreak severely impacted the Southern United States, and also affected Iowa and Nebraska to a lesser extent, between November 27–30, 2016. The strongest tornadoes of the event affected Alabama and Tennessee during the late evening of November 29 and into the early morning hours of November 30. Overall, this outbreak produced 48 tornadoes, killed six people, and injured many others.
The tornado outbreak of March 6–7, 2017 was a widespread severe weather and tornado outbreak that affected portions of the Midwestern United States in the overnight hours of March 6–7. Occurring just days after a deadly and more significant event across similar areas just a week prior, this particular outbreak led to 63 tornadoes within a 91⁄2-hour period as a quasi-linear convective system and discrete supercell thunderstorms traversed the region. The most notable aspect of the outbreak was an EF3 tornado that damaged or destroyed hundreds of structures within Oak Grove, Missouri, injuring 12 people but causing no fatalities. An EF1 tornado touched down near Bricelyn, the earliest known tornado on record in the state of Minnesota. Outside of tornadic activity, hundreds of damaging wind reports and a multitude of severe hail reports were documented.
The tornado outbreak and floods of April 28 – May 1, 2017 were a series of severe weather events that affected the central United States, producing life-threatening flooding and a major tornado outbreak. It formed out of a disturbance in the Southwestern United States on April 28, and caused significant impacts, including a heavy snowstorm in the Rockies, and other types of severe weather. Up to 3 feet (36 in) of snow fell on the cold side of the system, and up to a foot of rain fell in and around the central parts of the nation.
The April 2018 North American storm complex brought a wide swath of severe and winter weather that affected much of Midwest across to the East Coast of the United States. This particular outbreak led to at least 73 confirmed tornadoes over a three-day period, most of which occurred across Arkansas and Louisiana during the evening hours of April 13. The most significant tornadoes were an EF1 that caused a fatality in Red Chute, Louisiana, early on April 14, an upper-end EF2 tornado that impacted eastern sections of Greensboro, North Carolina on April 15, causing 17 injuries, and a significant EF3 tornado that impacted areas from Lynchburg to Elon, Virginia, causing severe damage and at least 10 injuries.
The March 2019 North American blizzard was a powerful Colorado Low that produced up to two feet of snow in the plains and Midwest. Rapid snowmelt following the storm caused historic flooding, and some areas received hurricane-force wind gusts. Comparable to the 1993 Storm of the Century, the storm was labeled a bomb cyclone after barometric pressure readings dropped in excess of 24 mbar (0.71 inHg) over a 24-hour period. After the storm entered Colorado from its origination in Arizona, the pressure dropped more than 30 mbar (0.89 inHg) and rapidly intensified over the western High Plains. The severe storm set new all-time record low barometric pressure readings in Colorado, Kansas and New Mexico. The storm itself killed only one person in Colorado, but flooding caused by the storm killed at least 3, one in Iowa and at least two in Nebraska and left ~140,000 without power in Texas.
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.
The tornado outbreak of April 17–19, 2019 was a multi-day, widespread severe weather event stretching from the South-Central United States to the East Coast of the United States. On the heels of a significant tornado outbreak just a few days prior, another potent upper-level trough progressed eastward and served as the impetus for widespread, damaging thunderstorms. The outbreak began on April 17 with several short-lived, generally weak tornadoes across Kansas, Oklahoma, and Texas. The following day, a total of 43 tornadoes were recorded across central Mississippi, tying the Hurricane Rita tornado outbreak as the largest in Mississippi state history. On April 19, the event spread eastward. North Carolina recorded 12 tornadoes, the state's sixth largest outbreak in a single day, while Virginia recorded 16 tornadoes, its third-most in a 24-hour period. Overall, 97 tornadoes were confirmed, the strongest of which was a high-end EF3 tornado that heavily damaged or destroyed homes and outbuildings near Rocky Mount, Virginia. There were no fatalities recorded in association with tornadic activity, but four people were killed by trees that were downed by strong straight-line winds.
On April 22, 2020, an outbreak of discrete supercell thunderstorms across portions of Oklahoma, Texas, and Louisiana led to widespread severe weather, including multiple strong tornadoes. Two people were killed by a high-end EF2 that struck the town of Madill, Oklahoma, and three more were killed by an EF3 wedge tornado that moved through Onalaska, Texas. Dozens of others were injured as well. The event came to fruition as a trough progressed eastward across the United States, interacting with a moist and unstable environment. Tornado activity continued into Arkansas, Louisiana, Mississippi, Alabama, Florida, and Georgia overnight into the day on April 23. Isolated tornado activity also occurred during the overnight hours on April 21.
A tornado outbreak occurred on Saint Patrick's Day in the Deep South. Mississippi and Alabama were greatly affected, with numerous tornadoes being confirmed, including four that were rated EF2. Six people were injured by four different tornadoes across Alabama during the outbreak. A non-tornadic fatality also occurred due to a car crash near Natchez, Mississippi. The outbreak began the day before, with a couple tornadoes in Mississippi, and continued over the next two days. The storm moved eastward and affected portions of Florida, Georgia, the Carolinas, and Virginia on March 18, spawning more tornadoes and causing wind damage before the storms pushed offshore that night. In total, 51 tornadoes were confirmed during the event, including 25 in Alabama, making it the sixth-largest tornado event in the state's history, and is sometimes locally referred to as the Saint Patrick's Day tornado outbreak of 2021. The same areas would be hit again by a more significant and destructive tornado outbreak sequence one week later.
Hurricane Ida generated a tornado outbreak as it traversed the Southeastern, Mid-Atlantic, and Northeastern United States. Thirty-five confirmed tornadoes touched down from Mississippi to Massachusetts; one person was killed in Upper Dublin Township, Pennsylvania, and several people were injured in Alabama, New Jersey, and Pennsylvania. The most active and destructive part of the outbreak occurred during the afternoon of September 1, when several strong tornadoes struck Maryland, New Jersey, and Pennsylvania, including an EF3 tornado which impacted Mullica Hill, New Jersey. 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 or it's remnants. This outbreak severely impacted New Jersey and the Philadelphia Metropolitan Area, a region which had been significantly impacted by strong tornadoes from another outbreak that occurred just over a month prior, as well as several weak tornadoes from the remnants of Tropical Storm Fred two weeks earlier. Overall, the 36 tornadoes killed one person and injured seven others.
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.
The April 2022 North American storm complex affected much of the Rocky Mountains and the Midwestern United States with tornadoes, heavy snow, and gusty winds. The system in general first began impacting the Northwest on April 11, before moving eastward into the Rocky Mountains the following day. It was also responsible for producing a large severe weather outbreak of tornadoes and damaging straight-line wind in the Midwest and South while contributing to a powerful blizzard in the upper Midwest states of North and South Dakota.
