What happened

The episode as NWS SHV wrote it up.

Scattered strong to severe thunderstorms developed across deep east Texas and northwest Louisiana during the afternoon hours of September 6th. These storms developed in a very unstable airmass with afternoon temperatures in the middle to upper 90s. These storms had tall cores and when they collapsed...they produced strong wind gusts which mainly downed trees and powerlines.

What forecasters said that day
