The tornado outbreak of November 30 – December 2, 2018 was a late-season tornado outbreak that occurred across portions of the West South Central states and Midwestern United States. As a potent shortwave trough moved across the southern portions of the country, it was met with ample moisture return and destabilization, resulting in widespread severe thunderstorms that produced damaging winds, hail, and tornadoes. The event began late on November 30 in Oklahoma, spreading east and resulting in one fatality in Aurora, Missouri. Several tornadic supercells moved across portions of Illinois on December 1, and resulted in 29 confirmed tornadoes. This outbreak was the largest December tornado event on record in Illinois history, surpassing the December 1957 tornado outbreak sequence. The most significant tornado of the event was an EF3 that impacted Taylorville, Illinois, damaging or destroying hundreds of structures and injuring 22 people. (Full article...)

A multi-day period of significant tornado activity along with significant derechos occurred across the Midwestern United States and the Mississippi Valley as well as an additional tornado in the Canadian province of Quebec. From May 19–27, 2024, two derechos occurred and tornadoes were reported across large portions of the Central United States, with multiple particularly dangerous situation (PDS) watches issued across the sequence. On May 19, strong tornadoes occurred with isolated supercells in Colorado and Oklahoma while a derecho produced widespread wind damage and weak tornadoes across Kansas into the early morning of May 20. Limited tornadic activity took place on May 20, but another outbreak along with widespread damage struck mainly Iowa and Wisconsin on May 21. Five fatalities were confirmed with a large, violent, long-tracked EF4 tornado that went through Greenfield, Iowa. Scattered to widespread severe weather and tornadoes occurred over the next two days, including an EF2 tornado that injured 30 people on the west side of Temple, Texas. Another derecho formed in southwestern Nebraska late on May 23 and moved eastward, producing widespread wind damage and weak tornadoes through Nebraska and Iowa and northwestern Illinois before withering away in the northern part of the state during the morning of May 24.

A nocturnal outbreak occurred during the overnight hours of May 25 into May 26. An isolated supercell in northern Texas produced multiple tornadoes, including a low-end EF3 tornado that passed near Valley View, Texas, killing seven people. Another longer-lived supercell moved through northeastern Oklahoma and across northern Arkansas, producing several tornadoes along with straight-line winds of 100 mph (160 km/h). Two fatalities were confirmed from an EF3 tornado that struck Claremore, Oklahoma along with areas near Pryor. Later, it produced a very large EF3 tornado near Decatur, Arkansas, which became the largest tornado ever recorded in Arkansas. Another EF3 tornado killed four people near Olvey and Pyatt while an additional tornadic death occurred with yet another EF3 tornado that passed near Yellville and through Briarcliff. Another supercell in southern Missouri produced a low-end EF3 tornado that passed near Morehouse and through Sikeston, killing two people indirectly. May 26 would be the most active day of severe weather; several rounds of squall lines and tornadic supercells moved through the Mid-Mississippi and the Ohio Valleys, producing widespread wind damage, large hail, and tornadoes. This included a very destructive, intense high-end EF3 tornado that prompted the issuance of four tornado emergencies across areas that had been previously impacted by the 2021 Western Kentucky tornado. One person was killed by this tornado. Severe weather activity became more isolated and scattered on May 27, marking the end of the outbreak sequence.

In all, 248 tornadoes occurred during the outbreak sequence; 20 (+1 indirect) people were killed by tornadoes while 10 other people died due to non-tornadic events as well. Over 240 people were injured. (Full article...)
