2Time from first tornado to last tornado

On March 21–22, 1952, a severe tornado outbreak generated eleven violent tornadoes across the Southern United States, which is the fourth-largest number of F4–F5 events produced by a single outbreak.[nb 2][nb 3][nb 4] Only the 1965 Palm Sunday tornado outbreak, the 1974 Super Outbreak, and the 2011 Super Outbreak surpassed this number. The outbreak caused 209 fatalities–50 of which occurred in a single tornado in Arkansas.[10][11] The severe weather event also resulted in the fourth-largest number of tornado fatalities within a 24-hour period since 1950.[12]

Background[]

A large low pressure system raced across the Northern Pacific before reaching the coast of the Southern Alaska panhandle on March 17. A new low formed from the original one and moved quickly southeastward through Canada and the Great Plains before turning eastward over Northern Oklahoma during the afternoon of March 19. It subsequently moved into Southwesten Missouri near Joplin and shot northeastward as another low that had formed in Nevada on March 19 surged into the region on March 21 and made a gradual northeastward turn through Northern Texas, Southeastern Oklahoma, and Northwestern Arkansas before turning northward on March 22 after it entered Illinois. Favorable conditions in the atmosphere led to a massive area of strong and severe thunderstorms that produced damaging winds, large hail, heavy rain, flooding, lightning, and tornadoes.[13]

The areas between Silerton and south-southwest of Lexington would be hit again by an F2 tornado just under one year later.[23][41][14]
F2 Southeastern Only Humphreys TN 35°51′N 87°41′W / 35.85°N 87.68°W / 35.85; -87.68 (Only (March 21, F2)) 05:55–? 0.3 miles (0.48 km) 500 yards (460 m) This brief, strong tornado destroyed several barns, damaged outbuildings, and unroofed three homes on farmsteads in and near and Buffalo.[23][41]

Non-tornadic effects[]

The weather system associated with the outbreak also produced several inches of snow across the central and northern Great Plains and the upper Midwest. Blizzard conditions affected Kansas, Nebraska, and South Dakota.[15] A significant blizzard affected the Great Plains. In Kansas, 15 in (38 cm) of snow were recorded. On March 22, Charles City, Iowa, documented 11.6 in (29 cm), which was the town's greatest 24-hour snowfall record at the time. Minnesota reported 17 in (43 cm), while Bergland, Michigan, reported 2 ft (0.61 m) of snowfall. Heavy snow and strong winds disrupted highways and road traffic. Flash floods also affected Sumner and Clay counties, Tennessee.[15]

Notes[]

  1. ^ All losses are in 1952 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. ^ 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]
  4. ^ 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]
  5. ^ a b All dates are based on the local time zone where the tornado touched down; however, all times are in Coordinated Universal Time for consistency.
  6. ^ a b Prior to 1994, only the average widths of tornado paths were officially listed.[16]

National Weather Digest. National Weather Association. 24 (4): 3–10. Archived from the original (PDF) on 18 December 2012. The authors sent a detailed letter to the SPC recommending the two tornadoes from 1974, and the 1952 tornado mentioned above, be downgraded to F4. The SPC agreed to all three of these changes. The SPC database now reflects the conclusions of Professor Fujita's map of 1974, and Grazulis 1952 tornado report (1993). ... The authors suggested that the three former F5 tornadoes in Tennessee should be reclassified as F4. These changes have been adopted, making the 16 April 1998 Lawrence County tornado the only documented F5 in the history of Tennessee.
