2Time from first tornado to last tornado

On May 4–6, 1960, a large tornado outbreak sequence affected parts of the Midwestern and Southern United States. The severe weather event produced at least 71 confirmed tornadoes, including five violent tornadoes in the U.S. state of Oklahoma. Major tornado activity began on the afternoon of May 4, with strong tornadoes affecting the Red River Valley and the Dallas-Fort Worth metroplex. Two F4 tornadoes struck parts of southern Oklahoma, causing significant damage to the Konawa and Soper areas. In all, at least 22 tornadoes formed between the early afternoon and late evening hours, with two more tornadoes forming early on May 5, shortly after midnight CDT. A much more significant tornado outbreak began on the afternoon of May 5 and continued overnight, spreading from eastern Oklahoma into portions of southern Missouri and Central Arkansas. At least 35 tornadoes developed between 6:00 a.m. CST on May 5–6, including a long-tracked F5 that struck rural areas in Northeastern Oklahoma and killed five people. Two other F4 tornadoes killed 21 people in and near Sequoyah County in the eastern portion of the state. Other strong tornadoes affected the Little Rock metropolitan area early on May 6 in Arkansas. In all, the tornado outbreak sequence killed 33 people and injured 302.[nb 2]

Prior to 1990, there is a likely undercount of tornadoes, particularly E/F0–1, with reports of weaker tornadoes becoming more common as population increased. A sharp increase in the annual average E/F0–1 count by approximately 200 tornadoes was noted upon the implementation of NEXRAD Doppler weather radar in 1990–1991.[3][nb 3] 1974 marked the first year where significant tornado (E/F2+) counts became homogenous with contemporary values, attributed to the consistent implementation of Fujita scale assessments.[7][nb 4] Numerous discrepancies on the details of tornadoes in this outbreak exist between sources. The total count of tornadoes and ratings differs from various agencies accordingly. The list below documents information from the most contemporary official sources alongside assessments from tornado historian Thomas P. Grazulis.

Notes[edit]

  1. ^ All losses are in 1960 USD unless otherwise noted.
  2. ^ 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]
  3. ^ 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.[4] Most countries only recorded tornadoes that produced severe damage or loss of life.[5] 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.[6]
  4. ^ 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.[8][9] Tornado ratings were retroactively applied to events prior to the formal adoption of the F-scale by the National Weather Service.[10] While the Fujita scale has been superseded by the Enhanced Fujita scale in the U.S. since February 1, 2007,[11] Canada used the old scale until April 1, 2013;[12] nations elsewhere, like the United Kingdom, apply other classifications such as the TORRO scale.[13]
  5. ^ All starting coordinates are based on the NCEI database and may not reflect contemporary analyses
  6. ^ 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.
  7. ^ The listed width values are primarily the average/mean width of the tornadoes, with those having known maximum widths denoted by ♯. From 1952 to 1994, reports largely list mean width whereas contemporary years list maximum width.[14] Values provided by Grazulis are the average width, with estimates being rounded down (i.e. 0.5 mi (0.80 km) is rounded down from 880 yards to 800 yards.[15][16]
