From April 26–28, 2024, a very large, deadly and destructive tornado outbreak occurred across the Midwestern, Southern, and High Plains regions of the United States, primarily on April 26 and 27. On April 26, the Storm Prediction Center (SPC) first issued an enhanced risk for the Plains, as a broad upper-trough moved eastwards, with strong tornadic activity erupting in the states of Nebraska, Iowa, and Kansas later that day, being more intense than forecasted. A high-end EF3 tornado struck the northeastern outskirts of Lincoln, Nebraska in Lancaster County, injuring three people. A long-tracked high-end EF3 tornado caused widespread severe damage in Elkhorn and near Bennington and Blair, and prompted the issuance of two tornado emergencies. Another EF3 tornado moved through parts of both Omaha and Council Bluffs, Iowa as well as points northeast, injuring four more people. Another long-tracked EF3 tornado moved directly through Minden, Iowa, killing one person and injuring three others, prompting the issuance of two more tornado emergencies. An EF2 tornado also moved through Pleasant Hill just southeast of Des Moines, injuring one person.
On April 27, a moderate risk was issued by the SPC for areas further south in Oklahoma and millions were put under a particularly dangerous situation (PDS) tornado watch. Several PDS tornado warnings were issued that day, especially during the nighttime hours, as strong to violent tornadoes touched down. A catastrophic high-end EF3 tornado moved directly through Sulphur, Oklahoma, killing one person and injuring 30 others. Another EF3 tornado destroyed multiple homes as it passed near Holdenville, killing two people. The strongest tornado of the night was a violent, low-end EF4 tornado that moved through the western part of Marietta, killing a person on I-35 and destroying a large warehouse and a grocery store. Only weak tornadoes touched down on April 28, but one high-end EF1 tornado caused a fatality and an injury when it destroyed a mobile home near Trinity, Texas.
The outbreak was the largest since a similarly large and deadly outbreak the year prior, although this one was spread out over a slightly larger time period and was not as deadly. Six people died as a result of this outbreak, and over 150 others were injured. With a grand total of 145 tornadoes over a two-day period, the tornado outbreak gained 87 points on the outbreak intensity score. The outbreak served as the beginning of a broader 16-day period of constant severe weather and tornado activity across the United States that would continue until May 10. (Full article...)June 16
- 1942 – A tornado struck southern Brazil, destroying many buildings including two hotels and a church. Reports from the day after indicate that more than 20 people were killed and hundreds were injured.
- 1992 – An F5 tornado moved through Chandler, Minnesota, destroying 75 homes and damaging more than 90 other structures. One person was killed and 40 were injured.
- 2014 – A strong supercell spawned a complex family of six tornadoes in northeastern Nebraska, four of which were rated EF4. The most destructive of these destroyed about half of Pilger and killed one person. A simultaneous EF4 tornado east of the town killed another person. Video of these twin tornadoes was widely shown in news media and online.

- 1944 – A significant tornado outbreak affected the Upper Midwest. An F5 tornado obliterated farms near Wilmot, South Dakota, killing eight people. An F4 tornado destroyed more farms near Henry and Florence, South Dakota and passed through Long Lake, killing three people. An F3 tornado destroyed 20 buildings and unroofed a school in Bath, South Dakota, leaving two dead. The tornadoes from this outbreak are only listed as windstorms in official records, even though well-defined funnels were spotted.
- 1946 – An F4 tornado touched down in Melvindale, Michigan and crossed the Detroit River, killing at least 15 people as it moved through Windsor and Tecumseh, Ontario.
- 1978 – An F1 tornado moved across Pomona Lake in Osage County, Kansas and capsized the tour boat Whippoorwill, drowning 16 of the 58 people on board and injuring 3 others. This was the deadliest tornado on record to receive a "weak" (F0 or F1) rating on the Fujita scale.

- 1939 – An F4 tornado moved through the Minneapolis–Saint Paul area, destroying 40 homes in Anoka, Maple Grove, and Champlin, killing nine people and injuring 222. Some homes were swept away. Four people died in a car that was thrown 300 yards.

- ...that the 2013 Moore tornado that struck Moore and Newcastle, Oklahoma, is the most recent EF5 tornado?
- ...that the 2021 South Moravia tornado, an IF4 tornado with winds between 207–260 mph (333–418 km/h), was the strongest tornado to hit the Czech Republic in modern history?

Sixty-six tornado tracks are plotted as colored lines on the map, with their colors corresponding to one of the eleven parent storm cells the tornadoes were produced by.

From May 2 to 8, 1999, a large tornado outbreak took place across much of the Central and parts of the Eastern United States, as well as southern Canada. During this week-long event, 152 tornadoes touched down in these areas. The most dramatic events unfolded during the afternoon of May 3 through the early morning hours of May 4 when more than half of these storms occurred. Oklahoma experienced its largest tornado outbreak on record, with 70 confirmed. The most notable of these was the F5 Bridge Creek–Moore tornado which devastated Oklahoma City and suburban communities. The tornado killed 36 people and injured 583 others; losses amounted to $1 billion, making it the first billion-dollar tornado in history. Overall, 50 people lost their lives during the outbreak and damage amounted to $1.4 billion.
On May 2, a strong area of low pressure moved out of the Rocky Mountains and into the High Plains, producing scattered severe weather and ten tornadoes in Nebraska. The following day, atmospheric conditions across Oklahoma became significantly more favorable for an outbreak of severe weather. Wind profiles across the region strongly favored tornadic activity, with the Storm Prediction Center stating, "it became more obvious something major was looming" by the afternoon hours. Numerous supercell thunderstorms developed across the state as well as bordering areas in Kansas and Texas. Over the following 48 hours, May 3–4, 116 tornadoes touched down across the Central United States. Following the extensive outbreak, activity became increasingly scattered from May 5 to 8, with 26 tornadoes touching down across the Eastern United States and Quebec.
(Full article...)The scope of WikiProject Severe weather is to write articles about severe weather, namely thunderstorms and tornadoes. Their talk page is located here.
WikiProject Weather is the main hub for all articles that are weather-related. WikiProject Weather strives to improve articles in a variety of weather topics, including Tropical Cyclones, Severe Weather, General meteorology, Non-tropical Storms, Climate, Floods, Droughts and wildfires, Meteorological instruments and data, Meteorological Biographies, and Space Weather. If you would like to help, please visit the project talk page.
WikiProject Meteorology is a collaborative effort by dozens of Wikipedians to improve the quality of meteorology- and weather-related articles. If you would like to help, visit the project talk page, and see what needs doing. The project is currently being merged into WikiProject Weather.
WikiProject Tropical cyclones is a daughter project of WikiProject meteorology. The dozens of semi-active members and several full-time members focus on improving Wikipedia's coverage of tropical cyclones.
Wikipedia is a fully collaborative effort by volunteers. So if you see something you think you can improve, be bold and get to editing! We appreciate any help you can provide!
