On April 20–22, 1912, a large tornado outbreak affected portions of the High Plains, the Upper Midwest, and the Southern United States, including portions of what is now known as the Dallas–Fort Worth metroplex. The severe-weather event produced at least 32 tornadoes, at least nine—and possibly 10 or more—of which were violent tornadoes, all of which rated F4 on the Fujita scale. Powerful tornado activity was distributed from the Great Plains to South Carolina. The first day of the outbreak occurred on April 20 and produced numerous strong to violent tornadoes across parts of North Texas, Oklahoma, and Kansas. A second day of intense tornadoes occurred on April 21, with several strong to violent tornadoes across Illinois and Indiana. The final day, April 22, produced an F4 tornado in Georgia as well. The entire outbreak killed 56 people, and was followed days later by another intense tornado outbreak on April 27. That outbreak killed about 40 people, mostly in Oklahoma. Both outbreaks produced a combined total of nine F4 tornadoes in Oklahoma alone.[nb 2][nb 3][nb 4]

Notes
- ↑ All losses are in 1912 USD unless otherwise noted.
- ↑ An outbreak is generally defined as a group of at least six tornadoes (the number sometimes varies slightly according to local climatology) with no more than a six-hour gap between individual tornadoes. An outbreak sequence, prior to (after) the start of modern records in 1950, is defined as a period of no more than two (one) consecutive days without at least one significant (F2 or stronger) tornado.[1]
- ↑ The Fujita scale was devised under the aegis of scientist T. Theodore Fujita in the early 1970s. Prior to the advent of the scale in 1971, tornadoes in the United States were officially unrated.[2][3] While the Fujita scale has been superseded by the Enhanced Fujita scale in the U.S. since February 1, 2007,[4] Canada utilized the old scale until April 1, 2013;[5] nations elsewhere, like the United Kingdom, apply other classifications such as the TORRO scale.[6]
- ↑ Historically, the number of tornadoes globally and in the United States was and is likely underrepresented: research by Grazulis on annual tornado activity suggests that, as of 2001, only 53% of yearly U.S. tornadoes were officially recorded. 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.[7] Most countries only recorded tornadoes that produced severe damage or loss of life.[8] Significant low biases in U.S. tornado counts likely occurred through the early 1990s, when advanced NEXRAD was first installed and the National Weather Service began comprehensively verifying tornado occurrences.[9]
- 1 2 3 All dates are based on the local time zone where the tornado touched down; however, all times are in Coordinated Universal Time and dates are split at midnight CST/CDT for consistency.
- 1 2 3 Prior to 1994, only the average widths of tornado paths were officially listed.[10]
