Broad troughing was present aloft across the Western US during the afternoon/evening of the 19th. An area of surface low-pressure slowly deepened and moved towards north-central Kansas, with dryline extending from central Kansas through western-north Texas by the late afternoon hours. A well-timed lead upper wave, combined with broken insolation, led to the development of a few supercell thunderstorms across central Oklahoma. Multiple instances of large to very large (>2 inches) hail, along with 18 tornadoes, occurred across central Oklahoma.

This eleventh tornado moved into Pottawatomie County from Cleveland County, crossing the county line just south of Lindsey Street/Little River Road. The tornado was becoming narrower quickly as it crossed the county line, from a maximum of 2200 yard width in Cleveland County to about 750 yards wide as it crossed the county line and continued to become narrower until dissipating about 3/4 mile after moving into Pottawatomie County. A home and a mobile home had shingle and siding damage, and trees and power poles were also damaged.

The twelfth tornado of the outbreak developed about 2 miles south-southeast of Pink. This tornado was very slow, moving only 0.6 mile in 5 minutes near the intersection of Okay Road and Willow View Road. A metal truss electric transmission tower collapsed in the tornado and is the source of the EF3 rating. The tornado also damaged at least two homes and numerous trees.

The fourteenth tornado of the outbreak developed north of Pink southeast of the intersection of Walker Road and Waco Road, and moved north-northwest and then northwest before moving into Cleveland County south of Lake Road. In Pottawatomie County, a number of homes, mobile homes and a church were damaged by the tornado with at least one home where the entire roof was removed.

A tornado developed in Bethel Acres near Bethel Road south of Clear Pond Road, and moved north-northwest dissipating northwest of the intersection of Bethel Road and Lake Road. At least one home and two mobile homes were damaged, including one mobile home that was partially pushed over. This was the sixteenth tornado of the outbreak.

The Shawnee Tornado was the seventeenth tornado of this outbreak. This large, mulitple-vortex tornado initially developed near New Hope Road and Gaddy Road just southeast of Bethel Acres. It moved northeast quickly become a large tornado with a width of up to 1.3 miles. The tornado moved northeast into Shawnee, then turned north moving through western and northern portions of Shawnee with damage at Oklahoma Baptist University, areas near the Shawnee Mall near Interstate 40 and Kickapoo Street, and numerous locations in Shawnee. The large tornado continued north and north-northwest producing damage along both Kickapoo Street and Leo Road all the way north to the Lincoln County line. The tornado moved into Lincoln County just west of Kickapoo Street and dissipated soon after.

The eighteenth and final tornado of this outbreak developed northeast of Johnson, or from 1 mile northwest to 1 mile west of Garden Grove. This tornado moved south near and just west of Econtuchka Road dissipating just southwest of the intersection of Econtuchka Road and Wolverine Road. A home received roof damage, an outbuilding was destroyed and trees were damaged along the path.

30 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.
