The wider storm

A cold front sagged southward into the region on April 30th, becoming positioned near the Interstate 10 and 12 corridors by the afternoon. A moist and unstable airmass remained in place from the previous day while a passing upper level disturbance helped showers and thunderstorms redevelop and intensify during the late afternoon. The strongest storms produced heavy rainfall over portions of the Baton Rouge metro area in a short period of time. The combination of slow-moving storms, locally heavy downpours, and urban drainage impacts led to flash flooding in parts of the metro area.

Began near Magnolia Woods (30.4200, -91.1500).
