Thunderstorms developed over north central and northwestern Oklahoma during the early evening of the 17th, near an outflow boundary from earlier thunderstorms, and north of a developing warm front that stretched across the area. The atmosphere ahead of the thunderstorms over eastern Oklahoma had become very unstable. The strong instability combined with strong wind fields and strong wind shear associated with an intense upper level disturbance moving through the region, resulted in a few supercells that evolved into a severe squall line that moved through the area during the mid to late evening of the 17th, and early morning of the 18th. Widespread damaging wind, multiple tornadoes, and large hail up to golf ball size occurred across northeastern Oklahoma as the storms moved through the area.

This tornado developed west of Baker Road and south of Grandview Road. It moved east-northeast, uprooting numerous trees and damaging an outbuilding. Based on this damage, maximum estimated wind in the tornado was 95 to 105 mph.

This tornado developed north of Burchett Road and west of Bryant Road. It moved east-southeast across the northern portion of Tahlequah, and then crossed Highway 10 and the Illinois River east of town. The tornado snapped and uprooted numerous trees along its path, some of which fell onto homes. This tornado produced a tornadic debris signature from the KINX and KSRX WSR-88Ds. Based on this damage, maximum estimated wind in the tornado was 105 to 110 mph.

This is the first segment of a two segment tornado. The tornado developed north of Highway 62 and west of the 742 Road. It moved east through the 580 Road, and then turned more southeast, crossing Highway 62, and then moved into Adair County. The tornado uprooted and snapped numerous trees, some of the trees fell onto homes. Based on this damage, maximum estimated wind in this segment of the tornado was 95 to 105 mph.

This is the second segment of a two segment tornado. The tornado moved into Adair County near the 754 Road, moved southeast and then turned to the east, before crossing the 4630 Road and dissipating. The tornado uprooted numerous trees. Based on this damage, maximum estimated wind in this segment of the tornado was 90 to 100 mph.

This tornado developed just west of the 4648 Road and north of the 770 Road.

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 Slight Risk, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 05:28 UTC.

29 more were confirmed in the United States that day.

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.
