The Tornado outbreak sequence of March 9–13, 2006 was an early season and long lasting tornado outbreak sequence in the central United States that started on the morning of March 9 and continued for over four days until the evening of March 13. The outbreak produced 99 confirmed tornadoes, which killed a total of 10 people. The Storm Prediction Center (SPC) issued multiple elavated outlook throughout the sequence, including a rare high risk for March 12, which would end up being the most intense day of the outbreak, producing 62 in total. 11 F3 tornadoes were tallied, and a violent F4 tornado touched down in Monroe County, Missouri, becoming the strongest of the outbreak. Multiple tornado emergencies were issued for tornadoes throughout the outbreak as well. An intense F3 tornado that affected the towns of Renick and Maddison in Missouri killed 4 people and injured dozens others, becoming the deadliest of the sequence. Multiple of the tornadoes were long-tracked in nature, with 6 of them having paths exceeding 30 miles (48 km). One particular supercell thunderstorm during the outbreak persisted for many hours and progressed in excess of 800 miles (1,300 km) through Oklahoma, Kansas, Missouri, Illinois, Indiana, and extreme southern Michigan.
From May 4–6, 2007, a major and damaging tornado outbreak significantly affected portions of the Central United States. The most destructive tornado in the outbreak occurred on the evening of May 4 in western Kansas, where about 95% of the city of Greensburg in Kiowa County was destroyed by an EF5 tornado, the first of such intensity since the 1999 Bridge Creek–Moore tornado. The supercell killed 13 people, including 11 in Greensburg and two from separate tornadoes. At least 60 people were injured in Greensburg alone. It was the strongest tornado of an outbreak which included several other tornadoes reported across Oklahoma, Colorado, Kansas and South Dakota that occurred on the same night.
A satellite tornado is a tornado that revolves around a larger, primary tornado and interacts with the same mesocyclone. Satellite tornadoes occur apart from the primary tornado and are not considered subvortices; the primary tornado and satellite tornadoes are considered to be separate tornadoes. The cause of satellite tornadoes is not known. Such tornadoes are more often anticyclonic than are typical tornadoes and these pairs may be referred to as tornado couplets. Satellite tornadoes commonly occur in association with very powerful, large, and destructive tornadoes, indicative also of the strength and severity of the parent supercell thunderstorm.
This page documents notable tornadoes and tornado outbreaks worldwide in 2009. 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. In the U.S., there were 1,304 reports of tornadoes received by the Storm Prediction Center (SPC), and 1,159 tornadoes were confirmed to have taken place. Worldwide, 73 fatalities were caused by tornadoes; 22 in the United States, 20 in India, 11 in Argentina, eight in the Philippines, four each in Canada and Brazil, two in Greece and one each in Serbia and Russia.

The six tornadoes in Oklahoma also tied the record for the most tornadoes ever recorded in the state during the month of February, which would later be broken in 2023. The first day of the outbreak produced the most tornadoes; the second brought mainly high wind damage and rain or snow in most of the Northeast.

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 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. 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 in the 2008 Super Tuesday tornado outbreak. 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 2010 New Year's Eve tornado outbreak was a three-day-long tornado outbreak that impacted the central and lower Mississippi Valley from December 30, 2010 to January 1, 2011.

Additionally, many areas reported tornado activity and lightning. Particularly hard hit were areas along the Blanco River in Hays County, Texas, where entire blocks of homes were leveled. On the morning of May 26, the National Weather Service issued a flash flood emergency for southwest Harris County and northeast Fort Bend County. The system also produced deadly tornadoes in parts of Mexico, Texas, and Oklahoma. This flood significantly contributed to the wettest month ever for Texas and Oklahoma.
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.
