Thunderstorm Wind in Shelby County, Texas

Structural straight-line wind damage was observed in the community of Jericho where a clustering of chicken houses was mostly to completely destroyed by northerly wind gusts estimated to be up to 100 mph.

Multiple supercell thunderstorms developed along a broad, diffuse baroclinic boundary across Northeast Texas throughout the day on June 8th. MLCAPE values were in excess of 4500 J/kg in proximity to these thunderstorms, with modest northwesterly mid-level flow contributing to 45 knots of effective bulk shear. Given the very weak convective inhibition, these thunderstorms persisted for several hours from early afternoon and throughout the evening. As a result, multiple severe reports of large hail and higher end damaging wind gusts were recorded across parts of Northeast Texas along with an isolated report of flash flooding in Mount Pleasant.
