Scattered showers and thunderstorms developed during the late afternoon through the evening hours of August 29th across Western Arkansas, near and just south of a weak surface front draped from Northeast Oklahoma into Western and Central Arkansas, and near an upper level disturbance shifting southeast through Arkansas. A very hot and humid air mass in place just ahead of the front fueled high amounts of instability, with these storms merging into a large mesoscale convective system (MCS) as they shifted south into extreme Southeast Oklahoma and much of Southwest Arkansas. Additional scattered strong to severe thunderstorms also developed over portions of Red River County Texas and McCurtain County Oklahoma, eventually merging into the MCS. As a result, much of this thunderstorm complex became severe, producing damaging winds which downed trees and power lines across McCurtain County Oklahoma and much of Southwest Arkansas during the late evening hours on the 29th through a portion of the early morning hours on the 30th. These storms gradually weakened overnight with diminished instability and as the primary upper level disturbance shifted east of the region.
