A warm front mixed north across portions of Deep East Texas to near the Louisiana/Arkansas border during the early morning hours of April 7th, but steep lapse rates aloft and a shortwave trough which ejected northeast over Northeast Texas, North Louisiana, and Southern Arkansas enhanced the development of scattered elevated strong to severe thunderstorms across portions of East Texas, North Louisiana, and Southwest Arkansas near and north of the front. A report of small hail near El Dorado was received from these storms during the early morning hours prior to daybreak, with flash flooding developing across Southern Columbia and much of Union Counties as thunderstorms continued to develop and move repeatedly over these same areas for much of the day. Widespread rainfall amounts of four to nearly ten inches fell over these areas through much of the daytime and evening hours on April 7th. Additional strong thunderstorms developed later in the afternoon ahead of the primary upper level trough that lifted east out of Southwest New Mexico and across much of Central Texas and Louisiana, resulting in additional flash flooding over these same areas. These storms eventually diminished during the evening hours once the upper trough shifted east of the region into the Lower Mississippi Valley.
