Thunderstorm Wind in Nevada County, Arkansas

Trees were blown down along Highway 278 in Eastern Nevada County.

A weak cold front slowly advanced southeast into portions of Northeast Texas, Southeast Oklahoma, into Western Arkansas and Southern Missouri on April 30th, and focused a warm, very moist, and unstable air mass in place across much of East Texas, North Louisiana, and Southwest Arkansas during the afternoon through the evening hours. Meanwhile, an upper low pressure area ejected northeast from the Desert Southwest into the Texas Panhandle, with deep southwest flow aloft yielding weak disturbances along the front to induce large scale forcing across much of East Texas and Southwest Arkansas. As a result, a complex of strong to severe thunderstorms developed and spread into areas along and to the southeast of the front, yielding instances of damaging winds across portions of Southwest Arkansas during the afternoon. An isolated tornado was also spawned just west of Lockesburg in Sevier County, before these storms gradually exited the region by early evening.
