Thunderstorms developed over eastern Oklahoma during the morning hours of the 30th as a warm front moved into the region from the south. The stronger storms produced large hail. Additional thunderstorm development occurred along and ahead of a dry line over central Oklahoma during the afternoon. These storms moved eastward into northeastern Oklahoma during the late afternoon and evening. Four tornadoes, two of which were strong, hail up to golfball size, and damaging wind occurred with these storms.

This is the third segment of a three segment tornado. In Rogers County, the tornado moved east-northeast passing across the northern portion of the Patriot Golf Club and Stone Canyon housing subdivisions. Numerous homes were damaged in this area, some severely. Several homes under construction were destroyed. The tornado crossed Highway 266 destroying a business, damaging a number of homes, destroying barns and outbuildings, and snapping or uprooting numerous trees until it dissipated north of Verdigris. Based on this damage, maximum estimated wind in this segment of the tornado was 110 to 120 mph.

This tornado damaged numerous homes east of Highway 66 and west of I-44. Some of the worst damage in the path occurred in a housing area near Highway 88 where several homes received severe damage to their roofs and wall structures. Several vehicles were rolled. The tornado moved east along the E 500 Road where trees were snapped or uprooted, homes were damaged, and barns were destroyed. The tornado then moved east-northeast toward Will Rogers Downs on Highway 20, where it turned sharply to the northeast and dissipated after damaging several large barns. Based on this damage, maximum estimated wind in the tornado was 120 to 130 mph.

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 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 01:15 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.
