Thunderstorm Wind in Butler County, Missouri

A trained spotter estimated 70mph gusts through Neelyville. A few windows were smashed, possibly by hail. Portions of multiple trees were damaged in and around Neelyville. Multiple surges of wind occurred in a brief period through town, north of the core of the storm.

With a west-east oriented boundary positioned through the Ozarks region of Missouri with low pressure positioned in Southwestern Missouri, a small but potent surging storm line pushed through Carter, Ripley, and Butler Counties mid-afternoon on the 28th. Large hail and winds in excess of 70mph were associated with this bowing segment as it dove east-southeastward from South Central Missouri into the Bootheel. A more intense pocket of wind known as a macroburst produced winds up to 100mph across portions of Ripley County from southeast of Doniphan to south/southwest of Naylor, uprooting dozens of trees and damaging several structures and multiple vehicles.

For the Carter-Ripley-Butler corridor, environmental parameters included: MLCAPE of 1000-2000J/kg, DCAPE of 500J/kg, very strong effective bulk shear of 60-70kts, and mid-level lapse rates of 6-7C/km.
