EF1 tornado in Pottawatomie County, 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.

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.
