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 Jul 6, 1:51 PM CST, 1 hour 39 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SHREVEPORT LA 251 PM CDT FRI JUL 6 2012 .DISCUSSION... ISOLATED CONVECTION HAS DEVELOPED THIS AFTERNOON AS EXPECTED ACROSS THE CWA. MAIN THREATS WILL BE HEAVY DOWNPOURS AND LOCALLY STRONG WIND GUSTS. STORMS WILL BE OUTFLOW DRIVEN PRIMARILY. TEMPERATURES HAVE CLIMBED INTO THE MID 90S TO NEAR 100 DEGREES AGAIN...BUT RELIEF APPEARS TO BE IN SIGHT. TODAYS AFTERNOON CONVECTION WILL LIKELY DIMINISH AFTER SUNSET...BUT SHORTWAVE ENERGY TO THE EAST WILL MOVE THROUGH THE AREA DURING THE EARLY MORNING HOURS SATURDAY...POSSIBLY SPARKING OFF SOME SHOWERS AND THUNDERSTORMS. HAVE KEPT IN SLIGHT TO LOW END CHANCE POPS TO COVER THIS POSSIBLE ACTIVITY. THE COMPRESSED H500 RIDGE OF HIGH PRESSURE TO THE NORTH OF THE AREA WILL BEGIN TO MOVE WESTWARD BY SUNDAY AFTERNOON. BEFORE IT DEPARTS HOWEVER...IT WILL CONTINUE TO PROVIDE THE CWA AND THE SE UNITED STATES WITH EASTERLY FLOW. IN THIS EASTERLY FLOW WILL BE A SERIES OF SHORTWAVE TROUGHS...WHICH WILL PROVIDE LIFT AND AID IN THE DEVELOPMENT OF SHOWERS AND THUNDERSTORMS. AFTER THE UPPER RIDGE DRIFTS WEST BY EARLY IN THE WEEK...A N/NW FLOW WILL SETUP. EMBEDDED IN THIS FLOW WILL BE A FRONTAL BOUNDARY. THIS FRONTAL BOUNDARY WILL BE ENTERING THE FORECAST AREA BY WEDNESDAY MORNING. FROM SUNDAY INTO THE DAY ON TUESDAY...WITH THE HELP OF SOME RESIDUAL UPPER LEVEL SHORTWAVE ENERGY...SHOWERS AND THUNDERSTORMS WILL BE COMMON...HAVE POSTED CHANCE TO LOW END LIKELY POPS. THESE SHOWERS AND THUNDERSTORMS WILL BE IN GREAT DEMAND AS DRY CONDITIONS CONTINUE TO PLAGUE THE AREA. SOME LOCATIONS COULD SEE AS MUCH AS 3 INCHES OF RAIN BY THE TIME THE FRONT MOVES THROUGH THE AREA WEDNESDAY EVENING. PWAT VALUES WILL BE VERY HIGH IN THE 2 PLUS INCH RANGE...HELPING ACHIEVE SOME OF THOSE HIGHER RAINFALL TOTALS. SOME LINGERING SHOWER ACTIVITY MAY BE POSSIBLE ACROSS EXTREME SOUTHERN AREAS AS THE FRONT WILL LIKELY STALL BEFORE MAKING IT TO THE GULF COAST. IN ADDITION TO THE GOOD NEWS ABOUT THE PROMISE OF RAINFALL ACROSS THE AREA...WIDESPREAD CLOUD COVER AND SOME LIGHT NORTHERLY WINDS IMMEDIATELY BEHIND THE FRONT WILL ALLOW FOR A TEMPORARY REPRIEVE FROM THE 100 DEGREE TEMPERATURES. HIGHS WILL BE KEPT DOWN IN THE LOWER 90S...ROUGHLY FROM SUNDAY THROUGH WEDNESDAY. LOWS WILL BE COMFORTABLE AS WELL...RUNNING CLOSER TO THE 70 DEGREE MARK RATHER THAN THE 80 DEGREE MARK. LOOKING OUT INTO THE LONG RANGE FORECAST...IT APPEARS AT THIS TIME THAT THE PATTERN REMAINS UNSETTLED. AT LEAST...NOT SEEING THE H500 HEAT DOME REBUILDING OVER THE CENTRAL US FOR A PERIOD OF TIME. /20/ && .AVIATION... MOSTLY VFR CONDITIONS SHOULD CONTINUE THROUGH THE UPCOMING 24 HOUR TAF PERIOD...WITH ONLY BRIEF PERIODS OF MVFR/IFR DUE TO SCATTERED THUNDERSTORMS. SCATTERED THUNDERSTORMS WILL BE THE MAIN WEATHER HAZARD FOR PILOTS THIS AFTERNOON INTO THE EARLY EVENING. EXPECT WIND GUST TO 50 KTS...EXTREME TURBULENCE AND HAIL AROUND THE STRONGEST STORMS WITH ISOLATED STORM TOPS APPROACHING 50 KFT. THE STORMS WILL MOVE AND BUILD TO THE WEST SOUTHWEST. LATER TONIGHT...
