May 1981 Tornado Outbreak
From Wikipedia, the free encyclopedia
The May 1981 Tornado Outbreak was a tornado outbreak that occurred on May 22 in western and Central Oklahoma and on May 23 from eastern and central Oklahoma to central Iowa. 43 tornadoes were reported during the two-day outbreak, of which 14 were recorded as strong or violent (F2 or greater on the Fujita Scale). The outbreak claimed no fatalies and there were only 12 injuries from a tornado that tore through Binger, Oklahoma causing significant damage. The tornado outbreak overall left $32.8 million dollars (1981 USD) in damage.[1][2]

[edit] Storm history
On the morning of May 22, 1981, winds moving in from the south brought moist air across Texas and into western Oklahoma and dry line formed across the Texas panhandle. In addition, the interaction between a layer of warm air aloft and the return flow of moist air lead to widespread low clouds across the state of Oklahoma. Later that day, the low clouds broke as predicted by forecasters as the dry line moved east into western Oklahoma. However, the clearing was limited to a relatively narrow zone ahead of the dry line. Despite this, daytime heating allowed thunderstorms to form by mid-afternoon.[1]
[edit] Cordell Oklahoma tornado
The first tornado formed northwest of Cordell, Oklahoma at 4:17 pm (CDT). The tornado damaged a mobile home and several barns as it moved northeast over a six mile path. The tornado was photographed by a storm chaser team during a project conducted by the National Severe Storms Laboratory and Mississippi State University. Many storm chasers sometimes nicknamed the tornado the "Wizard of OZ" tornado because of its unusual shape.[1]
[edit] Binger tornado
A second thunderstorm formed south of the thunderstorm that produced the Cordell tornado. The second thunderstorm moved northeast, causing some concern among officials and forecasters as the storm was heading directly towards Oklahoma City. The second thunderstorm produced 6-12 tornadoes across a wide area stretching from Fort Cobb Reservoir to Union City. The thunderstorm later encountered cooler, less unstable air and dissipated near Oklahoma City.[1]
One of the group of the tornadoes, the Binger Tornado which touched down near Binger at 6:45 pm (CDT). At the time of formation, it was a weak F1 Tornado until it reached a point of 3.5 miles, west-southwest of the Scott Neighborhood community. At that point it strengthened and reach F4 status 1 mile east of the neighborhood. The tornado maintained that strength as it crossed Highway 37 until it dissipated near the Canadian River. Damage from the tornado was severe as it destroyed an old uninhabited house outside of Scott. Two other houses were also destroyed but their walls remained intact. A mile east, the tornado ripped the roof, walls and carport off another house while two more houses were completely destroyed. In addition the tornado uprooted or damaged several trees and flipped over automobiles and farm equipment during its 16 mile duration.[3]
Near Highway 37, the tornado blew away several storage tanks at an Amoco oil storage facility. One of the tanks which was out of operation because of a lightning strike was found 1500 ft south of its original location. The other two tanks blown away by the tornado were never found. A 1/2 mile away, the tornado destroyed a farmhouse and a barn and wrecked a pickup truck. Because the path of the Binger Tornado was mostly over unpopulated areas and due to early warnings and observations, there were no fatalies or injuries.[3]
[edit] Other tornadoes
After the Binger tornado dissipated, a complex of severe thunderstorms regenerated further west across west-central Oklahoma near Foss Reservoir. The thunderstorms produced at least five tornadoes, one of which tore though Clinton, Oklahoma causing 12 injuries but no fatalies. In Alfalfa, Oklahoma, two tornadoes were reported, one which did F2 Damage.[1][4] Thunderstorms along and east of a line from Oklahoma City, Kansas City and Omaha, Nebraska produced 29 tornadoes on May 23 across Oklahoma, Missouri, Kansas and Iowa.
