F-Scale Killed Injured County Path
  04/25/1893 1830 45     31 many Cleveland/ Pottawatomie SW of Moore - near "Case" (12 E Moore)

This massive tornado, reportedly over a mile and a quarter wide at one point, moved northeast along a 15-mile path from northwest of Newcastle through rural areas between Norman and Moore (through what is now extreme northern Norman and extreme southern Moore), and swept away at least 30 homes. Thirty-three people were killed with 11 people dying in one home, 6 in a second home and 4 in a third home. This tornado was one of at least 5 strong/violent tornadoes in central Oklahoma on this day. This was the second tornado to affect areas near Norman this day with the first one passing just south and east of Norman. The local Norman paper reported that the first tornado "scared the people of Norman as they never have been scared before." In addition, there was a "general scampering from all parts and a hunt for caves was generally inaugurated."

  12/02/1953 2130 1.5 880 F1 0 1 Pottawatomie Shawnee

This tornado moved northeastward for 1.5 miles through the city of Shawnee. Trees and utility lines were downed by the storm. Three people were injured and total damages were estimated at $9,000. One man was injured when a fallen tree branch pushed through the windshield of his car and hit him as he entered the driveway of his home.

  05/01/1954 1800 59 n/a F4 0 65 Pottawatomie/ Lincoln/ Creek NE of Dale - Meeker - Sparks - Davenport - near Depew

The tornado was first reported at 6:00 pm CST northeast of the town of Dale in Pottawatomie County. It moved northeastward for 40 miles producing damage in the towns of Meeker, Sparks, and Davenport in Lincoln County. The tornado continued northeastward into Creek County, near the town of Depew. A total of 65 people were injured, but fortunately no one was killed. A large bus was carried 300 feet, and overturned on the U.S. Highway 62 just east of Meeker. Property damage was estimated at $820,000. In Lincoln County, 120 buildings were damaged or destroyed.

  09/14/1957 1730 68 440 F4 2 6 Cleveland/ Pottawatomie/ Seminole/ Hughes Southern Cleveland County NW of Wayne - near Sacred Heart - near Konawa - near Wetumka

This tornado formed northwest of the town of Wayne in McClain County near the Canadian River and moved nearly eastward along a hit-and-miss path. In southern Cleveland County, a damage path 3 miles long and 1/4 mile wide was documented. In this area, 3 barns were destroyed, trees snapped, and crops flattened by wind, rain, and hail.

The tornado continued almost due east and the worst damage was inflicted in a 7-mile-long area near Sacred Heart in southeastern Pottawatomie County and southwestern Seminole County. A tornado was observed 2 miles northwest of Konawa, OK at 6:55 pm CST. Two persons killed and 6 injured in 3 homes which were completely leveled along this path. Many other homes and buildings were damaged. Extensive damage occurred to oil field equipment and a total of 8 rigs were destroyed with losses estimated at $40,000.

Other wind damage was reported near Wetumka, OK, but this damage was probably unrelated to this tornado, and may have been related to another in a series of tornadoes produced by the same parent supercell thunderstorm or another supercell. It is possible that the damage caused in Wetumka was due to straight-line winds.

  09/14/1957 1756 0.5 43 F2 0 3 Pottawatomie Bethel (5 W Shawnee)

A tornado reported to have twin funnels struck the Bethel community 5 miles west of Shawnee.

This violent tornado formed just 2.2 miles west of Konawa and moved northeast before lifting 5 miles north of Konawa. Along the 8-mile damage path a total of 4 farmsteads that were completely destroyed. One new home was completely swept away. Fortunately, there were no fatalities or injuries as people in and near Konawa had taken refuge in their storm shelters. This was the first of 5 violent tornadoes that would occur during a two-day period in Oklahoma on May 4-5, 1960.

Several company homes were destroyed. Farmsteads were damaged and destroyed all along the rest of the rest of the long path northeastward.

Two people were killed and eleven injured in the Iron Post area south of Bristow, OK. This tornado caused the most damage as it moved through the west and north portions of Sapulpa, OK at 6:32 pm CST. Three persons were killed and 70 injured, and a total of 1000 people were homeless.

There were about 300 homes destroyed or damaged. Of this total approximately 100 homes were completely destroyed with 100 more receiving heavy damage and another 100 homes incurring partial damage. A school and 2 churches were also destroyed, and trees and utilities were heavily damaged. The storm covered a 12-15 block area in Sapulpa.

The funnel lifted northeast of Sapulpa and was observed aloft over Tulsa, OK at 7:00 pm CST. High winds destroyed a house in Tulsa and other general damage was reported. Large hail fell east and northeast of Shawnee, and some hail was observed near the entire path of the tornado.

  02/17/1961 1815 73 300 F3 0 11 Garvin/ Pontotoc/ Pottawatomie/ Seminole/ Hughes/ Okfuskee/ Okmulgee Stratford - Konawa - Wewoka - S of Schulter [tornado family.]

A parent supercell thunderstorm produced a series of tornadoes from Stratford to Konawa to Wewoka through areas in Okfuskee and Okmulgee counties. The first tornado hit Stratford where considerable damage occurred to 50 homes and several businesses. One person was injured by flying debris in Stratford.

The next report of a tornado occurred in Seminole County at Konawa where the tornado moved northeastward and cut a 3-blick-wide path of destruction through across the city and through the main business district. About 150 homes and 40 businesses were destroyed or damaged. Seven people were injured in Konawa.

The same tornado or possibly a new tornado skipped and only produced spotty damage until it reached Wewoka where about 75 houses were damaged in a path the was 2.5 blocks wide and 11 blocks long. Several farmstead were damaged and two people were injured when their car was picked up off OK State Highway 9 about 6 miles west of Wetumka.

  05/24/2011 1736-1739 2 50 EF2 0 32 Pottawatomie 4.5 SSW - 3.5 S McLoud

A tornado outbreak occurred over parts of northern and central Oklahoma during the day on May 24th, with violent tornadoes devastating several communities. By the end of the day, one EF-5, two EF-4, and two EF-3 tornadoes destroyed buildings, ripped up trees and power poles, and unfortunately, resulted in 11 deaths. The day began with a strong, upper-level trough ejecting out of the southwest United States. The trough took on a negative tilt as it approached the southern Great Plains. A strong jet stream was located at both the middle and upper levels rotating around the upper trough. At the surface, a low pressure strengthened rapidly over northwest Oklahoma, keeping the low-level flow of warm, moist air to flow east of a dry line that had moved into western Oklahoma. Thunderstorms developed by early afternoon over western Oklahoma, and quickly became supercellular as they moved northeast.

A tornado developed west-southwest of the intersection of Fishmarket Road and Memorial Road to the south-southwest of McLoud. The tornado moved east-northeast where a telephone company building lost its roof, and a number of sheds were damaged. The tornado caused tree damage as it crossed the intersection and Fishmarket and Memorial roads. Extensive tree damage continued northeast of this intersection, at least one home suffered the destruction of an attached garage and a few homes suffered roof and window damage. The tornado turned north-northeast crossing U.S. Interstate Highway I-40 near the Walker Road bridge where it struck and semi-truck, lifting and destroying the trailer, lofting the pieces to the north. The tornado dissipated soon after crossing U.S. Interstate Highway I-40. Although the tornado was very narrow, the rotational velocity of the tornado was observed to be very strong. Monetary damage estimates were not available.
