Thunderstorm Wind in Little River County, Arkansas

Trees downed throughout Little River County.

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 North Louisiana and South Arkansas, 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, isolated severe thunderstorms affected parts of Little River County Arkansas with sporadic reports of damaging winds.
