Strong to severe thunderstorms developed over western Oklahoma during the early morning hours of the 2nd, along and ahead of a cold front moving into the area. Moderately strong instability combined with strong low-level and deep layer wind shear resulted in the strongest storms developing organized rotation. A couple tornadoes and large hail up to quarter size occurred with the strongest storms in northeastern Oklahoma.

This is the first segment of a two-segment tornado. This tornado developed just west of Highway 75 and south of E 76th Street N, where large tree limbs were snapped. It moved east-northeast damaging several industrial buildings east of Highway 75, then moved northeast across a subdivision north of E 76th Street N, where numerous homes were damaged, trees were blown down, and power poles were snapped. The tornado then moved across several neighborhoods east of N Mingo Road and west of Highway 169, where numerous homes were damaged, trees were snapped or uprooted, and power poles were snapped. It then crossed into Rogers County near E 106th Street N. Based on this damage, maximum estimated wind in this segment of the tornado was 100 to 110 mph.

This is the second segment of a two-segment tornado. The tornado crossed into Rogers County near E 106th Street N, where the roofs of homes were damaged and large tree limbs were snapped. The tornado dissipated north of Highway 20 and east of N 177th East Avenue, where an outbuilding was destroyed. Based on this damage, maximum estimated wind in this segment of the tornado was 90 to 100 mph.

From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

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.

The county was under a tornado watch, issued at 07:46 UTC and running to 12:55 UTC.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. 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 Storm Prediction Center had this point in a Marginal Risk. The outlook in force was issued at 05:54 UTC.

SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

The radiosonde launches on either side of the tornado, from the nearest station that was launching then, drawn and analyzed the way Storm Lab does: the same diagram, the same parcel and shear definitions SPC's mesoanalysis uses.

The Tulsa radar (KINX), 28 km away, was scanning. The volume nearest the touchdown began at 11:34 UTC.

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.
