The episode as NWS SHV wrote it up.
A band of showers and thunderstorms producing heavy rainfall developed during the mid and late afternoon hours on April 19th, and moved repeatedly over the same areas across Northern Bienville and Southern Lincoln Parishes. Additional storms merged with this line, thus enhancing the heavy rain, and produced a band of two to four inch rainfall totals in one to two hours time over already saturated grounds from heavy rainfall that fell a week prior along the Interstate 20 corridor. This heavy rainfall event was in association of a plume of tropical moisture which surged north from the Gulf of Mexico ahead of a stationary upper level low pressure system over eastern Nebraska and Eastern Kansas. As a result, flash flooding developed which closed an intersection southeast of Bryceland, LA.
