EF2 tornado, Cole to Stella, Oklahoma, February 26, 2023

From Cole to Stella, this EF2 tornado ran 26.1 miles across McClain and Cleveland counties on February 26, 2023, touching down at 9:15 PM CST and reaching 900 yards wide. It killed nobody and injured 12, and did $50 million of property damage.

The rating scale

Tracks are drawn in the color of the rating. The Enhanced Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.

  1. EF065 to 85 mph

    Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.

  2. EF186 to 110 mph

    Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.

  3. EF2111 to 135 mphthis tornado

    Considerable damage. Roofs torn off well-built houses, frame homes shifted on their foundations, mobile homes destroyed, large trees snapped or uprooted, cars lifted off the ground.

  4. EF3136 to 165 mph

    Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.

  5. EF4166 to 200 mph

    Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.

  6. EF5over 200 mph

    Incredible damage. Strong frame houses swept off their foundations, car-sized missiles thrown more than 100 meters, steel-reinforced concrete badly damaged, high-rise buildings deformed.

  7. Unrated

    The survey recorded a tornado but could not put a number on it, most often because it crossed open country and damaged nothing a rating can be read from.

The damage survey

455 damage points were recorded along this path by NWS OUN, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF2. The highest wind the damage implies is 135 mph.

  • Southern extent of tornado. Picture looking west
  • Picture from alternate angle of earlier.
  • Several branches strewn across field. Large branch is about 8-10 inches in diameter
  • Open airport hangars with no doors. Lowered wind.

What the Weather Service recorded

A powerful storm system, with highly anomalous magnitudes of wind shear and moisture for late February, impacted the forecast area on the evening of the 26th. A broken line of severe thunderstorms developed across the eastern Texas Panhandle/far western Oklahoma and quickly swept through much of the forecast area. Widespread wind damage, including gusts near 90 mph, along with a record number of tornadoes (13) for February occurred. Several reports of large hail were also received. Behind the line of thunderstorms, a tight pressure gradient and strong westerly low-level jet allowed widespread 50-60 mph winds gusts to continue through the late evening hours.

This tornado developed just west of Pennsylvania Avenue about 1/2 mile south of 290th Street where it took the roof off an outbuilding. The tornado moved east-northeast damaging a mobile home along 290th Street, and then snapped a couple of power poles as moved into the city limits of Goldsby just east of SW 24th Avenue. The tornado caused roof and fence damage in a neighborhood near NW 12th Avenue and Center Road in Goldsby before moving across the Goldsby airport damaging hangars. The tornado then crossed the Canadian River into Cleveland County.

The tornado that moved through Goldsby in McClain County crossed the Canadian River and into Cleveland County moving swiftly through southern and eastern portions of Norman. The tornado passed less than one mile southeast of the National Weather Center, and damaged numerous homes in neighborhoods near 12th Avenue SE and Cedar Lane Road, and northeast of 24th Avenue SE and Imhoff Road as well as damaging apartments and businesses near the intersection of State Highway 9 and US Highway 77. EF2 damage was noted at several apartment buildings, homes and businesses in these areas. Moving northeast, the tornado moved into less areas with less density of homes and people, but still affected neighborhoods near 36th Avenue SE and Lindsay Street, 48th Avenue SE and Lindsey, and 60th Avenue SE and Alameda Street. The tornado continued northeast damaging trees, power lines and a few homes before dissipating in far southeast Oklahoma City near SE 125th Street and Dobbs Road. The tornado moved at over 60 mph.

A tornado developed just inside Cleveland County southwest of the intersection of Southeast 89th Street and Pottawatomie Road. A house and outbuilding suffered roof damage. The tornado moved east one-quarter of a mile before crossing Pottawatomie Road and moving into Pottawatomie County.

Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The forecast that day

The Storm Prediction Center had this point in a Moderate Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 00:59 UTC.

What this means

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
