Thunderstorm Wind in Panola County, Texas

An NWS Storm Survey was conducted south/southeast of De Berry TX, finding sporadic wind damage. A few snapped trees and large tree branches were found downed along FM Road 123 between County Road 323 and Oilfield Road. More tree damage was found along Oilfield Road, with a few snapped trunks along with large limbs and branches down.

Remnants of a pre-dawn mesoscale convective system (MCS) that developed over the southern High Plains propagated downstream into the Ark-La-Tex region during the afternoon hours on May 30th. Diurnal heating and weak convective inhibition allowed for renewed development of severe thunderstorms along the leading edge of this long-lived MCS. Surface temperatures warmed into the 80s ahead of this convection across East Texas and North Louisiana, which contributed to MLCAPE values on the order of 1500-2000 J/kg within a modestly sheared environment. Additionally, a shortwave trough associated with this convection promoted further advancement downstream into an air mass that was supportive of robust updrafts. As a result, numerous severe thunderstorms affected much of East Texas with widespread damaging winds and one large hail report. In addition, multiple reports of flash flooding and an isolated tornado were also documented.
