Question: Where do tornadoes most commonly occur in the us?

context: The tornado alleys in the southeastern U.S., notably the lower Mississippi Valley and the upper Tennessee Valley, are sometimes called by the nickname "Dixie Alley", coined in 1971 by Allen Pearson, former director of the National Severe Storms Forecasting Center (NSSFC). A 2018 study found in the U.S., over the study period 1979-2017, an overall eastward shift of tornado frequency and impacts - toward Dixie Alley. The study found, since 1979, relatively-lower tornado frequency and impacts in parts of the traditional Tornado Alley, especially areas from north-central Texas toward the Houston, TX area, and relatively-higher tornado frequency and impacts in parts of the Mid-South, especially eastern Arkansas, the greater Memphis, TN area and northern Mississippi - all areas near the heart of Dixie Alley - see especially Figure 4.

northern Texas, through Oklahoma, Kansas, Colorado, Nebraska, Missouri, Iowa, South Dakota, and North Dakota
context: The term was first used in 1952 as the title of a research project to study severe weather in areas of Texas, Oklahoma, Kansas, South Dakota, Illinois, Iowa, Missouri, Nebraska, Colorado, North Dakota, and Minnesota. It is largely a media-driven term although tornado climatologists distinguish peaks in activity in certain areas and storm chasers have long recognized the Great Plains tornado belt.

context: Nebraska is fifth overall for sheer numbers of tornadoes, while Indiana has had 88 violent tornado reports from the 1950–2006 period, more than any state except Oklahoma. Iowa reported 3,900 almost as many as Texas. The deadliest tornado in US history, the Tri-State Tornado, struck Missouri, Illinois, and Indiana in March 1925. St. Louis, Missouri and neighboring East St. Louis, Illinois have been hit more than once by violent tornadoes, the most notorious of which was the St. Louis Tornado of May 1896. The New Richmond Tornado of May 1899 and the Flint, Michigan tornado of June 1953 also rank amongst the deadliest tornadoes in US history. The region was badly hit by the Palm Sunday Tornado Outbreak in April 1965 and by the Super Outbreak of April 1974. According to NCDC figures for the 1950 to 2006 period, Nebraska reported 2,440 tornadoes followed by Iowa (2,185), Illinois (2,086), Missouri (1,922), South Dakota (1,487), Minnesota (1,477), Indiana (1,327), North Dakota (1,216), Wisconsin (1,185), Michigan (981), and Ohio (916).
question: What single state is where tornadoes most commonly occur in the us?
short_answers: Texas

Answer: Tornadoes are more common in the United States than in any other country or state. Most tornadoes in the United States occur in the Central United States, between the Rocky Mountains and Appalachian Mountains, and while there is no officially defined 'Tornado Alley' at its broadest this area includes areas of Texas, Oklahoma, Kansas, South Dakota, Illinois, Iowa, Missouri, Nebraska, Colorado, North Dakota, and Minnesota. Wisconsin, Indiana, and Ohio are sometimes included. The state where tornadoes most commonly occur is Texas. Storm Chasers recognize this as the Great Plains Tornado Belt.
