  04/29/1970 2225 171 250 F2 0 2 Jackson/ Kiowa/ Caddo/ Grady/ Canadian/ Oklahoma/ Logan/ Payne Near Olustee - 5 S Stillwater [tornado family. Not continuous path]

A supercell thunderstorm developed in southwestern Oklahoma during the evening of April 29th, and went on to produce a series of tornadoes from near Olustee in Jackson County to 5 miles south of Stillwater in Payne County. This event was originally thought to have been produced by a single, long-track tornado, but data analysis done by scientists at the National Severe Storm Laboratory (NSSL) and information collected from storm surveys, eyewitnesses, and media accounts indicate that multiple tornadoes were produced by a cyclic, parent supercell thunderstorm that moved northeastward at 45 mph during its lifetime.

A tornado was first reported near Olustee at approximately 10:25 pm CST on April 29th. Several sightings of tornadoes were reported along the path of the supercell, with a report of the dissipation of the last tornado occurring 5 miles south of Stillwater at 2:00 am CST on April 30th. The supercell thunderstorm was tracked on radar by the Nation Weather Service forecast office (then U.S. Weather Bureau) in Oklahoma City near the Will Rogers World Airport.

The greatest damage along the storm path was in the extreme northwest section of Oklahoma City. There, 30 homes value at $35,000 to $ 50,000 each were either destroyed of damaged.

At one point, southwest of Coyle in Logan County, a tornado picked up a mobile home and moved it 110-150 feet to the west of its original location while the storm continued on in a northeasterly direction. Two people were slightly injured in the mobile home. A pilot flew over the storm path from east of Guthrie in Logan County to south of Stillwater in Payne County, and reported seeing several intermittent damage paths within that flightline.

  04/30/1970 0100 47 500 F2 0 6 Grady/ Canadian/ Oklahoma 4 NW Pocasset - Mustang - Oklahoma City - 2 W Arcadia

The first report of damage from a tornado was located 4 miles northwest of Pocasset in Grady County, or 25 miles southwest of Oklahoma City. The tornado moved along a northeastward path through parts of Canadian and Oklahoma counties, and damaged was last reported 2 miles west of Arcadia. Only 2 or 3 people reported seeing the funnel, but a number of persons heard a loud noise, like that made by a jet engine.

In several areas roofs or buildings were moved at a right angle to the path of the storm, indicating a rotating column of air. Most of the damage occurred at Mustang in Canadian County, located just southwest of Oklahoma City, and along a path up to a half mile wide from the southwest corner of Oklahoma City to the northeast corner of the city.

A farmstead northwest of Pocasset received $10,000 in damages, and there was extensive damage to a home and several outbuildings 2 miles west of Arcadia. Two semi-trailer trucks were blown off the road and turn over on their sides along the westbound U.S. Interstate Highway I-40 lanes as the trucks were entering the Oklahoma City limits.

At Mustang, damages were estimated at $500,000 and were confined mainly to a shopping center and the city hall in the north part of Mustang. About 3 miles northeast of Mustang, a school building was extensively damaged and had most of its windows blown out.

One mile west of Mustang, wind equipment belonging to the National Severe Storms Laboratory (NSSL) recorded a wind speed of 110 mph. About 7 miles southwest of Mustang, a NSSL rain gauge measure 5 inches of rain.

In Oklahoma City, the damage was estimated at $6.3 million. Damage occurred to 1,473 homes, 293 businesses, 8 schools, 12 churches, and 300 signs. Southwestern Bell Telephone Company officials reported 30,000 telephones out of service, primarily in northwest Oklahoma City and Mustang. Oklahoma Gas and Electric officials reported that 215 utility poles were downed.

It is possible that several tornadoes were produced by the parent supercell thunderstorm instead of a single, long-track tornado.

  06/18/1973 1900 4 50 F1 0 1 Grady S of Rush Springs

A tornado damaged a mobile home south of Rush Springs where one woman was injured. A number of trees were downed along the 4-mile path. A fruit stand in the area was also damaged.

  04/20/1974 1500 64 100 F3 0 3 Grady/ Canadian/ Oklahoma/ Lincoln SW of Minco - 2 SE Mustang - S Oklahoma City - Del City - Midlothian

A funnel cloud was observed 3 miles southwest of Minco in Grady County at about 3:00 pm CST. The funnel touched down about 2 miles southwest of Mustang at 3:28 pm CST and periodically lifted and touched the ground again at it moved to the east-northeast at 30 mph. This tornado dissipated in Lincoln County at 5:30 pm CST.

The tornado passed about a mile south of the NWS forecast office located near the Will Rogers World Airport in Oklahoma City. Wind gusts of 66 mph along with 2-inch diameter hail were observed at the forecast office.

A major portion of the reported damage occurred as the storm moved through the southern Oklahoma City and Del City areas. There was extensive damage to homes in that area as several houses were unroofed. A total of 3 injuries were reported in the great Oklahoma City area. Fortunately, none of the injuries were serious.

As the continued moving to the east-northeast through eastern Oklahoma County, the next report of damage was 3 miles northwest of Harrah where several farm buildings were destroyed. Several more farm buildings were destroyed in the Midlothian area.

If more data had been available at the time, it is possible that 2-3 tornadoes may have occurred with one tornado dissipating and another tornado forming near the end point of the previous tornado. However, with the data that was available at the time, it appeared that one long-track tornado occurred.

  04/30/1981 2015 29 5 F2 1 4 Grady Near Minco - Chickasha - S of Rush Springs (* not a continuous track)

This tornado touched down near Minco, OK and moved south with an intermittent path to Chickasha, OK and Rush Springs, OK before lifting near Marlow, OK. Near Rush Springs, a four-month-old infant was killed and two adults were injured when the tornado destroyed a mobile home. Approximately $250,000 worth of damage occurred to a warehouse in Chickasha.

  03/13/1990 1644-1737 28 200 F2 0 1 Grady/ McClain/ Cleveland 1 W Bradley- Washington- Noble- 5 NE Noble

An outbreak of severe thunderstorms and tornadoes occurred during the afternoon and evening of March 13th and the early morning hours of March 14th. Many reports of large hail up to the size of softballs were received. A total of 10 tornadoes occurred in Oklahoma.

A strong tornado touched down 1 mile west of Bradley and moved northeast before dissipating 5 miles northeast of Noble. Near Bradley, 2 mobile homes were destroyed, while several homes and 3 barns were damaged.

In McClain County, the damage was intermittent from 5 miles west of Criner to U.S. Interstate Highway I-35 southeast of Goldsby. At least 8 mobile homes and several outbuildings were destroyed. In Washington, the second story of a home was destroyed and one injury occurred to a woman in a mobile home.

In Cleveland County at Noble, the damage was extensive. An apartment building lost part of its roof, and a mobile home was overturned. Several tractor semi-trailers were overturned at a warehouse. Numerous homes sustained roof and other structural damage in the Sky Ridge and Forest Hills subdivisions. The Noble High School stadium press box was destroyed, several light poles were snapped, and the scoreboard was demolished. Total damage was estimated between $750,000 and $1 million.

  05/03/1999 1646-1710 9 880 F3 0 4 Caddo/ Grady 2 WSW Laverty - 4 S Verden - 2.5 WNW Downtown Chickasha

This tornado developed about 3 miles north-northeast of Cement (or 2 miles west-southwest of Laverty) near the Caddo/Grady County border, and quickly intensified to a strong tornado with associated damage rated at the high end of the F3 scale. The tornado tracked northeast for 9 miles before dissipating 2.5 miles west-northwest of downtown Chickasha. Two homes had just a few interior walls standing (F3), one located near U.S. Highway 62 on the northwest side of Chickasha, and several wooden high tension power lines were downed. Several persons were injured south of Verden near the Caddo/Grady County border.

  05/03/1999 1712-1721 4 500 F2 0 4 Grady 2.5 NW Downtown Chichasha - Chickasha Airport (NW edge of Chicakasha) - 4 NNE Downtown Chickasha

This tornado developed 2.5 miles northwest of downtown Chickasha just north of U.S. Highway 62, and tracked northeast, striking the Chickasha Municipal Airport, resulting in high-end F2 damage to two hangar buildings and destroying several aircraft. An aircraft wing, believed to have originated from this airport was eventually carried airborne approximately 45 miles and dropped in southwest Oklahoma City.

Approximately 20 mobile homes near the airport were either damaged or destroyed with several persons injured. The tornado then crossed U.S. Highway 81 about 2 miles north of its intersection with U.S. Highway 62 destroying a large building, then dissipated 4 miles north-northeast of downtown Chickasha.

  05/03/1999 1726-1848 38 1760 F5 36 583 Grady/ McClain/ Cleveland/ Oklahoma 2 SSW Amber - far N Newcastle - SW Oklahoma City - N Moore-S Del City-W Midwest City

This violent, long-lived tornado was the most infamous of nearly 60 tornadoes that struck central Oklahoma during an unprecedented outbreak on this Monday afternoon and evening of May 3, 1999. The tornado was the 9th of 14 tornadoes produced by a supercell thunderstorm during the tornado outbreak. It formed around 5:26 pm CST about 2 miles south-southwest of Amber, OK, and grew rapidly to monstrous proportions as it headed to the northeast, paralleling U.S. Interstate Highway I-44. It moved across Bridge Creek and rural parts of northwest Newcastle, OK, causing continuous F4 and sporadic F5 damage. The tornado was estimated to be a mile in diameter in this area.

It weakened to F2/F3 intensity and narrowed to less than 1/4 mile in width as it crossed U.S. Interstate Highway I-44 and the Canadian River northeast of Newcastle and entered far south Oklahoma City, OK southwest of 149th Street and May Avenue around 6:12 pm CST. But it regained F4/F5 intensity and widened again to 1/2 to occasionally 3/4 mile as it moved northeast across south Oklahoma City, entering Moore, OK just west and north of 12th Street and Santa Fe Avenue.

Still moving northeast and still producing F4 and occasional F5 damage, it crossed U.S. Interstate Highway I-35 at the Shields Boulevard junction and moved into northeast Moore, at which point it weakened slightly to F3/sporadic F4 intensity and began a gradual turn to the left. This turn took the tornado more to the north-northeast as it crossed I-240 between Bryant Avenue and Sunnylane Road. It crossed southeastern Oklahoma City and entered Del City, OK as an F4 tornado, width 1/3 to 1/2 mile, along SE 44th Street between Sunnylane and Sooner Roads, and continued north-northeast to the northwestern part of Tinker Air Force Base, near SE 29th Street and Sooner Road.

Continuing to turn slowly, it moved almost due north but maintained F4 intensity as it crossed U.S. Interstate Highway I-40 just east of Sooner Road and continued north to between SE 15th Street and Reno Avenue. The tornado then weakened rapidly to F0/F1 intensity as it crossed Reno Avenue, and at 6:48 pm CST dissipated about 3 blocks north of Reno Avenue between Sooner Road and Air Depot Boulevard.

Totals from this tornado include 36 direct fatalities (12 in Bridge Creek, 1 in Newcastle, 9 in southern/southeastern Oklahoma City, 5 in Moore, 6 in Del City, and 3 in Midwest City), 5 indirect fatalities during or shortly after the tornado, 583 direct injuries, numerous indirect injuries (too many to count), 1800 homes destroyed, and 2500 homes damaged. The tornado was also the 100th tornado to strike the Oklahoma City area since 1890. Total damage was estimated at $1 billion.

  05/24/2011 1606-1701 33 880 EF4 1 48 Grady/ McClain/ Cleveland 2 S Chickasha - SW Oklahoma City (near SW 149th and Portland)

This tornado formed on the south side of Chickasha in Grady County, quickly doing EF-2 damage. Mobile homes were damaged and destroyed, trees were uprooted or destroyed, outbuildings were destroyed, and many buildings lost significant portions of their roofs. One fatality occurred as a mobile home was destroyed in the south portion of Chickasha. As the tornado moved northeast of Chickasha, it gained significant strength, with several areas receiving EF-4 damage. Well-built homes were destroyed. Trees were debarked with only stumps remaining. Cars were thrown hundreds of feet. Almost continuous EF-3/occasional EF-4 damage occurred northeast until it crossed into McClain County, 1.5 miles south of OK State Highway 9. The tornado was probably at its strongest as it neared/crossed the Grady/McClain County line. Wind speeds there were estimated near 200 mph in this area.

Significant damage continued as the violent tornado moved over the McClain County border. This may have been the strongest portion of this tornado, with wind speeds near 200 mph. Well-built homes were destroyed, with some cleaned off of their foundation. A concrete dome home was severely damage, mainly by the flying debris. Trees were debarked or destroyed. Very little was left standing for the first few miles into McClain County. Fairly consistent EF-3, with brief periods of EF-4 damage occurred as the tornado approached and then crossed OK State Highway 9, near the OK State Highway 76 junction. The tornado began to weaken as it moved toward the Cleveland County border, with mainly trees and power poles/lines snapped.

The tornado continued into Cleveland County and where some minor tree/power pole/power line damage occurred. A few barns and outbuilding also sustained minor damage east of U.S. Interstate Highway I-44. The tornado dissipated just north of the Canadian River. The tornado traveled along a path length of 32 miles through three counties in just under an hour, Peak wind speeds were estimated just under 200 mph.

  05/24/2011 1626-1705 23 880 EF4 0 61 Grady/ McClain 2 W Bradley - 1 W Goldsby

This violent tornado developed west of Bradley in Grady County, downing tree limbs as it moved northeast. The tornado began to increase in intensity, producing EF-3 damage, as it approached McClain County. Although the damage was confined to trees, the severity of the damage became more intense along the path. Trees were snapped at the bases, or debarked altogether. The tornado was several hundred yards wide as it neared the Grady/McClain County line. Luckily, very few structures were in the path.

Widespread tree damage and ground scouring was ongoing as the tornado crossed into McClain County. As the tornado crossed OK State Highway 76, even more intense damage occurred. EF-4 damage was surveyed at several locations. Several homes were reduced to a pile of rubble, or were wiped clean off of their foundations. Automobiles were mangled and almost unrecognizable. The tornado weakened and narrowed as it crossed CR 410. Even though the tornado had weakened, it still produced EF-2 to EF-3 damage as it approached OK State Highway 39.

The tornado increased in intensity once again near OK State Highway 39, with EF-4 damage occurring in a second area along the path. Well-constructed homes were destroyed, with several wiped clean off of their foundations. This also began a longer streak of higher end damage, with EF-3 to EF-4 damage produced by the tornado until it crossed OK State Highway 74B, west of High Avenue. Equally devastating destruction occurred over the areas of EF-4 damage. The tornado lifted west of Goldsby with some EF-3 damage still occurring prior to lifting. It should be noted that this tornado had estimated winds up to 200 mph at times, falling just short of the damage indicator for an EF-5 tornado.
