What happened

The episode as NWS SHV wrote it up.

A large upper level ridge of high pressure centered over New Mexico during the daytime hours of July 30th, extended north and east across the Plains into the Mississippi Valley, resulting in a deep northerly flow into the Lower Mississippi Valley. An upper level shortwave trough rounding the center of the upper ridge axis shifted south across the Lower Mississippi Valley during the morning through the mid-afternoon hours, which when combined with daytime heating and a very warm, moist, and unstable air mass in place, resulted in increased large scale forcing that allowed for areas of showers and thunderstorms to develop over the southern sections of Northcentral Louisiana. These storms continued to develop and move repeatedly over the same areas of Eastern and Southern Grant Parish into much of Rapides Parish/adjacent Central Louisiana parishes, with widespread rainfall amounts of 5-8 inches falling, with localized heavier amounts in excess of 11 inches measured in the Ball community in extreme Northern Rapides Parish. This resulted in areas of flash flooding across Southern Grant Parish in the Bentley community, where several roads were flooded and closed and water had entered several homes.
