Overview

An upper level shortwave moving south through western Kansas helped to spark showers and thunderstorms in the northwest combined Panhandles during the afternoon hours on July 4th, 2021 . Storm development was also aided by a surface trough draped from northeast New Mexico into the western Oklahoma Panhandle. These storms formed in an environment with ample low level moisture and instability, with at least modest shear for multicell and supercell storm structures. These thunderstorms moved south southwest across the western combined Panhandles, a few of which did become severe. Hail up to 2 inches in diameter and flooding were reported near Dalhart while winds up to 78 mph were reported at the Boise City mesonet station. Strong winds were reported at several different mesonet stations in the Oklahoma Panhandle and western Texas Panhandle through the evening, with wind damage reported in the Washburn area with a storm that occurred after midnight.
