What happened
The episode as NWS SHV wrote it up.
A very unstable airmass developed across East Central and Central Louisiana during the afternoon of September 28th. This airmass was ahead of a stalled frontal boundary which had been stationary through much of the day. A strong upper level disturbance moved into the region from the northwest and helped to trigger strong to severe thunderstorms across the region. These storms produced large hail.
