This article describes severe weather terminology used by the National Weather Service (NWS) in the United States, a government agency operating within the Department of Commerce as an arm of the National Oceanic and Atmospheric Administration (NOAA).
The NWS provides weather forecasts, hazardous weather alerts, and other weather-related products for the general public and special interests through a collection of national and regional guidance centers (including the Storm Prediction Center, the National Hurricane Center and the Aviation Weather Center), and 122 local Weather Forecast Offices (WFO). Each Weather Forecast Office is assigned a designated geographic area of responsibility—also known as a county warning area—that are split into numerous forecast zones (encompassing part or all of one county or equivalent thereof) for issuing forecasts and hazardous weather products.

Selected tornado list -
This is a list of all tornadoes that were confirmed by local offices of the National Weather Service in the United States in November and December 2011. Based on the 1991–2010 averaging period, 58 tornadoes occur across the United States throughout November, while 24 more occur in December.
Similar to the prior months, November and December remained slightly below average with 46 and 15 tornadoes respectively. However, a couple days in November saw heightened periods of activity. Oklahoma recorded its first violent November tornado since modern records began in 1950, an EF4 tornado in Tillman County on November 7. Twenty tornadoes struck the South on November 16, including a long-track EF2 tornado in parts of Alabama and Georgia and two additional EF2 tornadoes that resulted in five fatalities in the Carolinas. December activity was confined to three consecutive days towards the end of the month, the highlight being a 13-tornado event primarily in Alabama and Georgia on December 22. Floyd County, Georgia was struck by EF2 and EF3 tornadoes, both of which caused considerable damage. (Full article...)

2025 tornado activity
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 hours 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 hours 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...)

Featured Article or List -
Although historically the U.S. state of Connecticut is not typically known to fall casualty to tornadoes, more than 100 of these powerful storms have affected the state in modern history, resulting in at least 48 deaths, 780 injuries, and more than $500 million in damage. This list of tornadoes in the state is likely incomplete, as official records date back only to 1950 for tornadoes in the United States.
As with most of the northeastern United States, the number of tornadoes peaks in the summer months, normally in July or August. Hartford County has had the most tornadoes in the state, although since 1950 Litchfield County has reported the most tornadoes. Several areas have been struck more than once, and Waterbury has been struck by no less than four tornadoes since 1955. (Full article...)
