From April 26 to 27,1991,multiple supercells across Oklahoma and Kansas led to a regional tornado outbreak. Forced by a potent trough and focused along a dryline,these distinct thunderstorms moved northeast through a moist and highly unstable environment. A total of 55 tornadoes were confirmed,many of which were strong,F2 or greater on the Fujita scale. A widely documented F5 tornado tore through Andover,Kansas,killing 17 people. Additional fatalities occurred from significant tornadoes in other portions of Kansas and Oklahoma,with 21 deaths recorded in total. An F4 tornado was detected by a mobile doppler weather radar team which observed winds up to 270 mph (430 km/h) at the top of the funnel,the first time winds of F5 intensity were measured by radar,and the highest winds recorded by radar at the time. A news team filming an F2 tornado sought shelter under a Kansas Turnpike overpass,causing a misconception that overpasses can provide adequate shelter during a tornado. This outbreak occurred within a transition period for the National Weather Service and proved the value of NEXRAD radars,which were utilized in Oklahoma to provide advanced warning to residents.
On Tuesday,April 10,1979,a widespread and destructive outbreak of severe weather impacted areas near the Red River between Oklahoma and Texas. Thunderstorms developed over West and North Central Texas during the day within highly unstable atmospheric conditions following the northward surge of warm and moist air into the region,producing large hail,strong winds,and multiple tornadoes. At least 22 tornadoes were documented on April 10,of which two were assigned an F4 rating on the Fujita scale;four of the tornadoes caused fatalities.
There is a long history of destructive tornadoes in the St. Louis metropolitan area. The third-deadliest,and the costliest in United States history,the 1896 St. Louis–East St. Louis tornado,injured more than one thousand people and caused at least 255 fatalities in the City of St. Louis and in East St. Louis. The second-costliest tornado also occurred in St. Louis in September 1927. More tornado fatalities occurred in St. Louis than any other city in the United States. Also noteworthy is that destructive tornadoes occur in winter and autumn,as well as the typical months of spring. Additionally,damaging tornadoes occur in the morning and late at night,as well as the more common late afternoon to early evening maximum period.
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 elevated 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.
The Great Storm of 1975 was an intense winter storm system that impacted a large portion of the Central and Southeast United States from January 9–12,1975. A classic Panhandle hook,the mid-latitude cyclone produced an outbreak of 45 tornadoes in the Southeast U.S. resulting in 12 fatalities,while later dropping over 2 feet (61 cm) of snow and killing 58 people in the Midwest. This storm,which caused blizzard conditions,remains one of the worst blizzards to ever strike parts of the Midwest,as well as one of the largest January tornado outbreaks on record in the United States.
This page documents notable tornadoes and tornado outbreaks worldwide in 2004. Strong and destructive tornadoes form most frequently in the United States,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,and Australia. Tornadic events are often accompanied with other forms of severe weather,including strong thunderstorms,strong winds,and hail.

This page documents the tornadoes and tornado outbreaks of 1982,primarily in the United States. Most tornadoes form in the U.S.,although some events may take place internationally. Tornado statistics for older years like this often appear significantly lower than modern years due to fewer reports or confirmed tornadoes.
This page documents notable tornadoes and tornado outbreaks worldwide in 1973,but mostly features events in the United States. According to tornado researcher Thomas P. Grazulis,documentation of tornadoes outside the United States was historically less exhaustive,owing to the lack of monitors in many nations and,in some cases,to internal political controls on public information. Most countries only recorded tornadoes that produced severe damage or loss of life. Consequently,available documentation in 1973 mainly covered the United States. On average,most recorded tornadoes,including the vast majority of significant—F2 or stronger—tornadoes,form in the U.S.,although as many as 500 may take place internationally. Some locations,like Bangladesh,are as prone to violent tornadoes as the U.S.,meaning F4 or greater events on the Fujita scale.

The first six days of December 1953 produced a destructive and deadly tornado outbreak sequence across the Southern United States. There were 19 confirmed tornadoes,including a violent F4 tornado that hit the northwest side of Alexandria,Louisiana and even more violent F5 tornado that hit Vicksburg,Mississippi. In all,the tornadoes killed 49 people,injured 404 others,and caused $45,709 million in damage. The death toll made this deadliest December tornado outbreak ever recorded and it would not be surpassed until 2021. This was also the last of the series of deadly and catastrophic tornado outbreaks to strike the US in 1953.
A deadly and destructive outbreak sequence of 23 tornadoes struck parts of the Great Plains and the Great Lakes in late-June 1957. At least seven significant tornadoes (F2+) touched down during the outbreak sequence. The most devastating storm was a large,violent,and catastrophic 500-yard-wide F5 tornado family that struck Fargo,North Dakota on Thursday,June 20,1957,killing 10 people and becoming the deadliest tornado ever recorded in North Dakota. The outbreak caused 11 fatalities,105 injuries,and $25.883 million in damage.
