EF0 tornado in Pottawatomie County, Oklahoma

A tornado developed southwest of US Highway 177 and Acme Road and moved northeast through the northwestern portion of Shawnee. A few homes had shingle damage and there were some sheds, fences, metal buildings, trees and power poles damaged along the path.

During the early morning of the 26th, ahead of a strong upper wave passage, a quasi-linear convective system (QLCS) developed across portions of central into eastern Oklahoma. Despite strong kinematics (wind shear) in place, the initial phase of the linear complex was rather benign (in terms of severe weather outcomes). However, as the complex overspread the Interstate 35 corridor, organization increased rapidly, including the development of several strong mesovortices. A cluster of weak tornadoes and wind damage occurred across portions of east-central Oklahoma, associated with these mesovortices. By the afternoon, while stronger synoptic support had lifted into portions of the Missouri Valley, strong convergence along a trailing boundary/pseudo-dryline promoted development of a few transient storms. A report of small hail was received with one of these storms across Seminole County.
