The episode as NWS SHV wrote it up.
Showers and thunderstorms developed across portions of north central Louisiana during the afternoon and evening of August 1st. The activity developed due to a disturbance aloft which helped trigger the storms along with previously existing outflow boundaries in place across the region. The ambient temperature approached triple digits just prior to storm development which led to vigorous updrafts and strong damaging wind gusts.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Shreveport, LA wrote its last area forecast discussion before the first event at Aug 1, 2:30 PM CST, 1 hour 20 minutes earlier.
