EF2 tornado, Purcell, Oklahoma, January 8, 2026
This EF2 tornado ran 9.4 miles across McClain and Cleveland counties on January 8, 2026, touching down at 7:24 AM CST. It killed nobody.
Preliminary. This is NWS OUN's damage survey, filed in the Damage Assessment Toolkit as Purcell. The rating, the path and the casualties are the survey's and can change while it is revised. The Storm Prediction Center compiles the official record of 2026 from these surveys and publishes it in the spring of 2027; this page moves to that tornado's permanent address when it does.
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.
EF065 to 85 mph
Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.
EF186 to 110 mph
Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.
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.
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.
EF4166 to 200 mph
Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.
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.
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.

What the survey found
This tornado developed near 180th Street and Ladd Road southwest
of Purcell and moved northeast. One home about 3 miles southwest
of Purcell had the roof removed. The tornado moved through
Purcell causing roof damage to a few homes and damaging utility
poles and trees. Moving out of the northeast side of Purcell, the
tornado crossed the Canadian River into Cleveland County. One
outbuilding was significantly damaged north of Lexington.

What the Weather Service recorded
A fast-moving quasi-linear convective system (QLCS) swept across portions of central, southern and eastern Oklahoma on the morning of the 8th. This convective system was tied to the passage of a compact upper wave across the region, resulting in very strong wind fields within a weakly unstable boundary layer. In addition to sporadic pockets of thunderstorm wind damage, and generally sub-severe hail, a few tornadoes occurred in a corridor from near Purcell, OK to Shawnee, OK.
This tornado developed near 180th Street and Ladd Road southwest of Purcell and moved northeast. One home about 3 miles southwest of Purcell had the roof removed. A semi on Interstate 35 just west of Purcell was pushed over injuring one person. The tornado then moved through Purcell causing roof damage to a few homes and damaging utility poles and trees. Moving out of the northeast side of Purcell, the tornado crossed the Canadian River into Cleveland County.

The warnings
No tornado warning for this county appears in the archive as in force at the moment the tornado touched down. One was issued for the county at another hour that day.

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 Slight Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 12:35 UTC.

What this means
Ratings are the survey's, read off the damage rather than measured; the rating scale is above. A survey can be revised, so the rating, the path and the casualties can all still change.
