A Mesoscale Convective Vortex (MCV) that was a remnant of showers and thunderstorms over Central Oklahoma on July 11th, drifted east into Southwest Arkansas during the early morning hours of the 12th. This upper level disturbance moved over an area that was very warm, moist, and unstable, and focused a cluster of showers and thunderstorms throughout much of the morning hours before drifting east out of the region by midday. These showers and thunderstorms moved repeatedly over the same areas, and were efficient rainfall producers such that flash flooding was widespread across portions of Southwest Arkansas. Widespread rainfall amounts of 3-6 inches, with isolated higher amounts in excess of 8 inches, fell across portions of Southwest Arkansas before ending by the mid morning hours on the 12th. In addition, an isolated tornado was spawned from this cluster of thunderstorms over Eastern Lafayette County just south of Stamps before these storms shifted east of the region later that morning.
