Strong to severe thunderstorms developed into eastern Oklahoma during the early morning hours of the 4th, as a strong storm system translated from the Southern Rockies into the Southern Plains. Instability was weak but wind shear was very strong ahead of the attendant surface low pressure system and frontal boundaries. This allowed the thunderstorms to produce several tornadoes and damaging wind gusts.

This tornado developed west of the S 210 Road and south of the E 111 Road, where large tree limbs were snapped. It moved northeast across Henryetta Golf and Country Club uprooting and snapping numerous trees, and damaging outbuildings. It then crossed Lake Road, where homes were damaged, outbuildings were destroyed, and trees were uprooted. The tornado dissipated east of Lake Road and north of Country Club Road. Based on this damage, maximum estimated wind in the tornado was 90 to 100 mph.

This tornado developed south of New Lake Road and east of the S 230 Road, where trees were snapped. It moved northeast across I-40, crossed Holly Road damaging outbuildings, and then Arbeka Road, where large tree limbs were snapped. It then dissipated north of Holly Road and east of Arbeka Road. Based on this damage, maximum estimated wind in the tornado was 90 to 95 mph.

This tornado developed west of the N 270 Road and north of Gun Club Road, where an RV was rolled and large tree limbs were snapped. It moved east-northeast across the N 280 Road, where the roof of a home was damaged, and several power poles were snapped. The tornado then crossed Smith Road, blowing down power poles and damaging a home. It moved northeast across Highway 52 snapping large tree limbs and damaging the roof of another home before dissipating. Based on this damage, maximum estimated wind in the tornado was 90 to 95 mph.

This tornado developed west of the N 330 Road and south of Watts Road, where large tree limbs were snapped. It moved northeast crossing the N 340 Road, where large tree limbs were snapped, and then crossed McKinley Road, damaging the roof of a house. It then crossed the N 350 Road, where large tree limbs were snapped, and dissipated south of Gun Club Road. Based on this damage, maximum estimated wind in the tornado was 75 to 80 mph.

20 minutes of warning. NWS TSA issued a tornado warning for this county at 11:50 UTC, 20 minutes before the tornado touched down, in force until 12:30 UTC.

The county was under a tornado watch, issued at 11:52 UTC and running to 13:51 UTC.

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 06:00 UTC.

36 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.
