The episode as NWS SHV wrote it up.
Several strong to severe thunderstorms developed across northwest and north central Louisiana during the afternoon and early evening hours of August 16th. These storms developed behind a nearly stationary frontal boundary and were moving from northeast to southwest across the northern half of the state. A weak shear axis existed across the state at that time and the storms developed in a moderately unstable airmass.
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 16, 9:31 AM CST, 3 hours 24 minutes earlier.
AREA FORECAST DISCUSSION

1031 AM CDT MON AUG 16 2010
.DISCUSSION...
FRONTAL BOUNDARY AS OF 15Z WAS LOCATED SOUTH OF THE I-20 CORRIDOR
WITH GOOD ISOBARIC PACKING NOTED NORTH OF THE BOUNDARY DESPITE
DEWPOINT TEMPERATURES IN THE 70S. CONVECTION CONTINUES TO DEVELOP
SOUTH OF THE BOUNDARY ACROSS THE LOWER TOLEDO BEND AND SAM RAYBURN
COUNTRY OF WEST CENTRAL LOUISIANA AND DEEP EAST TEXAS. THIS WILL
BE THE FAVORED AREA FOR CONVECTION THROUGH THE AFTERNOON... ALONG
AND SOUTH OF THE BOUNDARY. CANNOT RULE OUT ISOLATED ACTIVITY NORTH
OF THE BOUNDARY THUS...POP FORECAST LOOKS GOOD FOR THE REMAINDER
OF THE DAY. TEMPERATURES RUNNING SOME 3 TO 10 DEGREES COOLER THAN
THOSE OF 24 HOURS AGO ALONG AND NORTH OF THE BOUNDARY AS WELL. IT
MAY BE A STRUGGLE TO REACH HEAT ADVISORY CRITERIA ACROSS OUR
EXTREME NORTHERN ZONES BUT IT WILL BE CLOSE ENOUGH TO LET THE
ADVISORY RIDE FOR THE REMAINDER OF THE DAY. FCST HIGH TEMPERATURES
ARE IN THE BALL PARK SO NO CHANGES IN THE TEMPERATURE DEPARTMENT.
DID MAKE SOME COSMETIC CHANGES CONCERNING THE HEAT INDEX GRIDS BUT
THAT CHANGE WILL NOT NECESSITATE AN UPDATE TO THE ZONE PACKAGE
THIS MORNING.
