The episode as NWS SHV wrote it up.
Much like June 29th, a very unstable airmass developed during the late afternoon and evening hours of June 30th. A weak shear axis existed across portions of Northwest Louisiana and strong to severe thunderstorms developed along this axis. Additional storms developed along residual outflow boundaries and this caused storm to train and produce very heavy rainfall amounts.
