Severe thunderstorms developed over central Oklahoma along and ahead of a dry line during the afternoon of the 19th, as an upper level disturbance approached the Southern Plains. These thunderstorms moved northeast off the dry line and across portions of northwestern Arkansas during the evening hours. The atmosphere east of the dry line across northwestern Arkansas became very unstable during the afternoon and evening, and this instability combined with strong deep-layer and low-level wind shear, resulted in the development of a severe squall line. Multiple tornadoes and large hail up to quarter size occurred with these thunderstorms across portions of northwestern Arkansas. Locally heavy rainfall also produced some flash flooding.

This tornado developed north of Highway 412, just east of the Carroll County line and moved east toward Dryfork. The tornado snapped and uprooted numerous trees. Based on this damage, maximum estimated wind in the tornado was 100 to 105 mph.

This tornado developed along and just west of Highway 103, south of Osage. It moved northeast across Highway 412, and dissipated after crossing County Road 905. The tornado snapped and uprooted numerous trees, and damaged outbuildings. Based on this damage, maximum estimated wind in the tornado was 95 to 105 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 Moderate Risk, with a 0.15 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 00:59 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.

43 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.
