On May 12, 2022, a severe squall line followed by a derecho took place across the Midwestern United States. Two fatalities occurred from the first line of storms while three more deaths occurred from the derecho itself.
In the leadup to the derecho, temperatures were very warm. Sioux Falls, South Dakota saw a high of 94 °F (34 °C). Temperatures in the 90s helped fuel the severe weather that later erupted over the Great Plains. [5] On May 10, 2022, the Storm Prediction Center noted the elevated probabilities for severe weather to materialize, as atmospheric conditions over western Minnesota, northwestern Iowa, northeastern Nebraska, eastern South Dakota, and southeastern North Dakota were favorable for thunderstorms to develop. The development of a mid-level shortwave trough in this area, combined with the arrival of a cold front over a low-pressure area in the vicinity of the Dakotas, prompted the issuance of a Day 3 enhanced risk over the area, with a large 30% hatched area (indicating a ≥10% chance of significant severe weather) for severe weather to develop. The next day, the SPC maintained the enhanced risk for the same general areas of the upper Great Plains, but introduced a large 30% area for damaging winds, alongside a smaller 45% corridor for destructive winds over southwestern Minnesota, eastern South Dakota, and extreme northwestern Iowa. A 10%, unhatched area for tornadoes (indicating a <10% chance of EF2 or stronger tornadoes) was also included in the outlook, placed over northeastern South Dakota, southeastern North Dakota, and west-central Minnesota. While the outlook favored a more linear mode composed of a long squall line, the possibilities for individual supercell thunderstorms was also discussed. [6]
As the day of the event arrived, the SPC maintained the enhanced risk for the same general areas as the overall expected scenario, but part of the 45% wind risk area was hatched at the 1300 UTC outlook, requiring the issuance of a moderate risk in its 1300 UTC outlook centered in west-central Minnesota, eastern South Dakota, and extreme southeastern North Dakota. At 1525 UTC, the SPC issued a PDS Severe Thunderstorm Watch [7] for a prolific wind event with hazards of winds expected of 105 MPH. By 1630 UTC, the SPC slightly expanded the moderate risk area to encompass more area of east-central South Dakota. The outlook also introduced a small 10% hatched corridor for tornadoes, noting the possibilities for a few strong tornadoes to occur ahead of the main line. 3500-4500 J/kg CAPE values placed themselves over the area of concern, alongside 300-500 m2/s2 helicity and 45-55-kt wind shear, hence the increase for tornado potential. However, the main risk continued to be severe wind. [6]
As the evening advanced, the forecasted severe line of thunderstorms developed in the central Great Plains, eventually advancing towards the greatest area of concern. As such, hundreds of wind reports were received by the SPC over the course of the day, some discussing wind gusts of up to 105 miles per hour (169 km/h), as was the case in Tripp, South Dakota. Multiple reports of fatalities were received, as the damaging winds claimed at least three lives throughout the Plains. [8] At least three people were killed by the storms. [3] [9] While the event was primarily dominated by the severe derecho that developed, multiple tornadoes were also reported, mainly in South Dakota and Minnesota. A brief but high-end EF2 tornado caused severe damage in the town of Gary, South Dakota, [10] while a long-tracked EF2 tornado impacted Wadena County, Minnesota, causing damage to vehicles and barns along its track. [11]
The derecho affected portions of northeastern Iowa, Minnesota, Nebraska, southeastern North Dakota, and South Dakota. Its strong winds lofted and accumulated a thick cloud of dust, resulting in a haboob that accompanied the derecho. [8] South Dakota governor Kristi Noem reported that 28 counties in the state sustained damage, with the severity of the effects leading to a declaration of a state of emergency. A wind gust of 107 mph (172 km/h) was measured near Tripp, South Dakota. [3] In Madison, South Dakota, wind gusts topped out at 97 mph (156 km/h). [8] At least three people were killed by the storms. [3] Two people in Minnehaha County, including one in Sioux Falls, were killed by flying debris from the storm. Another person was killed in Kandiyohi County, Minnesota, after a grain bin was thrown onto a vehicle by strong winds. [8] Severe weather suspended a baseball game between the Minneapolis Twins and Houston Astros. [12] With 68 hurricane-force wind gusts, this broke the record from December 15, 2021 for the most hurricane-force wind gusts in a derecho. [13] Portions of I-29 and I-90 closed. [14]

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 February 2016 North American winter storm was a strong winter storm that caused more than 70,000 people in southern California to lose their electricity, with many broken trees and electrical lines in that area, with the Southern Rocky Mountains having the potential to receive some of the greatest snowfall from the system. One person in San Diego, California area died when a tree fell on their car. Another person in Minnesota died after being struck by a car while crossing a street.
This page documents notable tornadoes and tornado outbreaks worldwide in 2017. Strong and destructive tornadoes form most frequently in the United States, Brazil, Bangladesh, and Eastern India, but they 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 and Australia. Tornadic events are often accompanied with other forms of severe weather, including strong thunderstorms, strong winds, and hail. There were 1,522 reports of tornadoes in the United States in 2017, of which 1,418 were confirmed. Worldwide, 43 fatalities were confirmed in 2017: 35 in the United States, five in China, two in Paraguay, and one in Brazil.
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 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.
A destructive, two-day tornado outbreak affected the Great Lakes region of the United States and the National Capital Region of Canada in late-September. A total of 37 tornadoes were confirmed, including a violent long-tracked high-end EF3 tornado that moved along a 80 km (50 mi) path from near Dunrobin, Ontario to Gatineau, Quebec, and an EF2 tornado in the Nepean sector of Ottawa. The tornadoes in Ottawa-Gatineau were declared one of the ten most significant weather events of 2018 in Canada by the Meteorological Service of Canada.
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.
This page documents notable tornadoes and tornado outbreaks worldwide in 2020. 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. There were 1,243 preliminary filtered reported tornadoes in 2020 in the United States in 2020, and 1,086 confirmed tornadoes in the United States in 2020. Worldwide, at least 93 tornado-related deaths were confirmed with 78 in the United States, eight in Vietnam, two each in Canada, Indonesia, and Mexico, and one in South Africa.
The tornado outbreak of January 10–11, 2020 was a two-day severe weather event stretching from the South-Central Plains eastward into the Southeast United States. An eastward-moving shortwave trough tracked across the continental United States through that two-day period, combining with abundant moisture, instability, and wind shear to promote the formation of a long-lived squall line. Hundreds of damaging wind reports were received, and 80 tornadoes occurred within this line, making it the third largest January tornado outbreak on record. Three tornadoes—an EF1 in eastern Texas, an EF2 in northern Louisiana, and an EF2 in western Alabama—led to a total of seven deaths, all in mobile homes. There were five other storm related deaths, including two due to icy roads in Lubbock, Texas, one due to drowning in Oklahoma, and one due to icy roads in Iowa. The system also brought a monthly record high temperature to Boston and Bridgeport. Extensive damage and several other injuries occurred as well. The severe weather event was notable in that it was forecast well in advance, with the Storm Prediction Center first highlighting the risk area a full week beforehand. Total damage from the event reached $1.1 billion according to the National Centers for Environmental Information.
A significant severe weather event impacted the South Central United States between October 20–22, 2019. Forecasters first identified the threat on October 16 as a large upper-level trough was expected to combine with an unstable atmosphere across Texas, Oklahoma, and Arkansas particularly. On the evening of October 20, discrete supercell thunderstorms developed across the Dallas–Fort Worth metroplex, contributing to several tornadoes. One of those tornadoes caused EF3 damage in the Dallas suburbs, becoming the costliest tornado event in Texas history, at $1.55 billion. A later squall line contributed to additional tornadoes and a widespread swath of damaging winds as the system tracked eastward.
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.
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.
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.
On December 15, a rapidly-deepening low-pressure area contributed to a historic expanse of inclement weather across the Great Plains and Midwestern United States, resulting in an unprecedented December derecho and tornado outbreak across portions of the Northern United States, a region normally affected by snow and cold weather during this time of year. Non-thunderstorm winds spurred the formation of rapidly-moving fires across Colorado and western Kansas, with attendant dust and debris spreading eastward. From central Kansas northeastward into eastern Wisconsin, the powerful derecho led to hundreds of damaging wind reports. 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. Numerous embedded circulations within this rapidly-progressing derecho produced dozens of tornadoes, including 33 that were rated EF2. The culmination of non-thunderstorm, thunderstorm, and tornadic winds caused widespread damage to structures, trees, power lines, and vehicles across the Plains and Midwest. At least 600,000 people lost power on December 15, and temperatures dropped significantly across the affected region following the event, causing accumulating snow, which hindered cleanup and recovery efforts. The storm killed at least 5 people directly, as well as 2 people indirectly through wildfires partly spawned by the storm, and caused at least $1.8 billion in damages. The number of tornadoes in this event broke a record for largest outbreak in the month of December that had been set less than a week prior. The event also became one of the largest single-day outbreaks in recorded history, with 120 tornadoes occurring over an eight-hour period.
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.
