The episode as NWS SHV wrote it up.
Isolated pulse type severe thunderstorms developed across portions of Northeast Texas during the early evening hours of July 1st. These thunderstorms developed in a moderately unstable airmass with convective temperatures near 100 degrees. Once these thunderstorms collapsed...they produced strong wind gusts which downed trees.
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 1, 2:27 PM CST, 3 hours 48 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SHREVEPORT LA 327 PM CDT FRI JUL 1 2011 .DISCUSSION... A HOT AND HUMID AFTERNOON ACROSS THE REGION...THIS TIME WITH VERY LITTLE CONVECTION. TEMPERATURES WERE NEARING 100...BUT NOT QUITE HIGH ENOUGH TO GET CONVECTION GOING. ANY ISOLATED CONVECTION THAT DOES FORM SHOULD DIMINISH SHORTLY AFTER SUNSET. WILL KEEP 20 POPS GOING FOR FIRST 3 HOURS TO COVER. MODELS IN GOOD AGREEMENT WITH LITTLE CHANGE IN THE PATTERN OVER THE FOUR STATE REGION FOR THE START OF THE HOLIDAY WEEKEND. THE UPPER RIDGE WILL REMAIN CENTERED OVER THE MID MISSISSIPPI VALLEY SATURDAY AND THEN BEGIN TO SHIFT INTO THE WESTERN U.S. AS A TROUGH DIGS SOUTHEAST INTO THE OHIO VALLEY BY LATE SUNDAY INTO MONDAY. THIS WILL CREATE A WEAKNESS IN THE UPPER LEVELS WHICH WILL REMAIN OVER THE FOUR STATE REGION THROUGH MUCH OF NEXT WEEK. WITH THE RIDGE CENTERED WELL TO THE WEST...HIGH TEMPERATURES SHOULD HOLD IN THE MID AND UPPER 90S AND WIDELY SCATTERED CONVECTION WILL BE ABLE TO DEVELOP DURING AFTERNOON HEATING. ANY SHORT WAVES WRAPPING AROUND THE RIDGE WILL BRING ADDITIONAL NOCTURNAL CHANCES FOR RAIN. DEWPOINTS WILL RUN A LITTLE HIGHER NEXT WEEK...BUT STILL LOOKING FOR HEAT INDEX READINGS TO REMAIN JUST BELOW ADVISORY CRITERIA DUE TO THE LOWER TEMPS. IN THE SHORT TERM...AFTERNOON MIXING WILL LOWER DEWPOINTS INTO THE MID AND UPPER 60S. && .AVIATION... PEAK HEATING AND A WEAK STATIONARY FRONT HAVE COMBINED TO LEAD TO ANOTHER ROUND OF ISOLATED TO WIDELY SCATTERED AFTERNOON TSTMS. TSTM COVERAGE MAY INCREASE DURING THE LATE AFTERNOON AND EARLY EVENING HOURS. TIMING OF ANY TSTM IMPACTS AT TAF SITES WILL BE DIFFICULT IF COVERAGE REMAINS ISOLATED AND SPOTTY. DRY LOW LEVELS AND INVERTED V FORECAST SOUNDINGS CONTINUE TO INDICATE THE POTENTIAL FOR GUSTY WINDS WITH ANY TSTMS AND THE POSSIBILITY FOR DOWNBURSTS AS THEY COLLAPSE. CONVECTION SHOULD BEGIN TO DIMINISH BY 02/03Z WITH THE LOSS OF DAYTIME HEATING. VFR CONDITIONS ARE EXPECTED TO PREVAIL...ALTHOUGH LIGHT AND VARIABLE WINDS COULD ALLOW FOR SOME MVFR CIGS/VSBYS BETWEEN 02/09Z-02/14Z IN ANY LOCATIONS THAT RECEIVE SIGNIFICANT RAINFALL. /09/ && .PRELIMINARY POINT TEMPS/POPS...

WHILE THE THUNDERSTORM ACTIVITY IS NOT EXPECTED TO BECOME WIDESPREAD...HOT AFTERNOON TEMPERATURES WILL RESULT IN A MODERATELY UNSTABLE ATMOSPHERE. THESE STORMS...

OTHERWISE...NO HAZARDOUS WEATHER IS EXPECTED AT THIS TIME. .DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY... HOT TEMPERATURES AND SLIGHT THUNDERSTORM CHANCES WILL CONTINUE THROUGH THE UPCOMING HOLIDAY WEEKEND.

KEEP IN MIND THAT IF ANY OUTDOOR ACTIVITIES ARE PLANNED OVER THE NEXT SEVERAL DAYS...THESE STORMS WHILE NOT WIDESPREAD....WILL BE PROLIFIC LIGHTNING PRODUCERS. IF YOU HEAR THUNDER...THEN IT IS TIME TO MOVE INDOORS. OTHERWISE...NO HAZARDOUS WEATHER IS EXPECTED AT THIS TIME. .SPOTTER INFORMATION STATEMENT... SPOTTER ACTIVATION SHOULD NOT BE NEEDED FOR A LARGE AREA...BUT ISOLATED STRONG TO SEVERE THUNDERSTORMS WILL BE POSSIBLE THE NEXT SEVERAL DAYS.
