The episode as NWS SHV wrote it up.
A ridge of high pressure was located across the Tennessee Valley during the afternoon hours of September 11th. Weak perturbations aloft were moving from east to west under the ridge and provided the lift needed for widely scattered thunderstorms to develop during the afternoon hours. Storms produced strong wind gusts across Southwest Arkansas.
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.

WIDELY SCT CONVECTION HAS DEVELOPED THIS AFTERNOON ACROSS E TX/SE OK/SW AR/WRN LA...WITH CONVECTION MORE ISOLATED FARTHER E ACROSS NCNTRL LA/SCNTRL AR. THIS CONVECTION HAS BEEN TIED MAINLY TO AN UPPER LOW STILL SITUATED OVER E TX /PER WATER VAPOR IMAGERY/...WITH A WEAK SHEAR AXIS FARTHER NE ACROSS WRN AND CNTRL AR INTO THE OH VALLEY. CONVECTION HAS ACTUALLY BEEN NUMEROUS ACROSS THE WRN SHV METRO AREA...WITH THUNDER HEARD HERE AT THE NWS OFFICE...ALTHOUGH THE AIRPORT HAS YET TO RECORD RAIN AND THUS...THE STREAK OF CONSECUTIVE DAYS WITHOUT RAIN CONTINUES AT 28 DAYS. THIS CONVECTION...AS WELL AS THE CONVECTION TO THE E HAS BEEN TIED TO VARIOUS OUTFLOW BNDRYS WHICH HAVE BEGUN TO PROPAGATE W. MUCH OF THIS CONVECTION SHOULD BEGIN TO DIMINISH THIS EVENING WITH THE LOSS OF HEATING...ALTHOUGH THE SHORT TERM PROGS MAINTAIN ELEVATED THETA-E RIDGING ACROSS E TX/N LA...WHICH COINCIDES WITH THE WEAK SHEAR AXIS AHEAD OF THE UPPER LOW AS IT BEGINS TO SINK S LATER TONIGHT ONCE MID LEVEL RIDGING RETROGRADES W INTO CNTRL AR. HAVE MAINTAINED SLIGHT CHANCE POPS OVERNIGHT FOR THESE AREAS...WHICH MAY ALSO HELP FOCUS ISOLATED CONVECTION THURSDAY OVER THE REGION EVEN AS THE MID LEVEL RIDGE CONTINUES TO RETROGRADE W INTO ERN OK. THE PATTERN SHOULD BEGIN TO CHANGE SLIGHTLY FRIDAY THROUGH THE WEEKEND...AS AN UPPER TROUGH...NOW DIGGING SE INTO ND/NRN MN...DIVES SE INTO THE GREAT LAKES AND OH VALLEY...WITH ITS TRAILING TROUGH AXIS SLIPPING S ACROSS THE MID AND LOWER MS VALLEY FRIDAY. THIS TROUGH WILL HELP NUDGE A WEAK COOL FRONT SSW INTO SE OK/SW AR FRIDAY MORNING...MIXING ACROSS E TX/N LA DURING THE AFTERNOON. THE MODELS DO NOT GENERATE MUCH IN THE WAY OF FRONTAL CONVERGENCE OVER THE REGION FRIDAY...WITH LITTLE IN THE WAY OF DEEP LYR FORCING AND MOISTURE PRESENT WITH THE FROPA. ONLY THE NAM IS BULLISH WITH CONVECTION DEVELOPING MAINLY S OF I-20 FRIDAY AFTERNOON...AND PREFER THE MORE CONSERVATIVE GFS/ECMWF/CANADIAN SOLUTIONS WITH THE CONVECTION MORE TIED TO THE BAROCLINIC ZONE WHICH WILL LAG THE FRONT A WAYS INTO EXTREME NE TX/SW AR/EXTREME NRN LA. ISOLATED CONVECTION WILL REMAIN POSSIBLE FRIDAY NIGHT AND SATURDAY NEAR AND JUST BEHIND THE BNDRY AS IT SLIPS SW INTO CNTRL LA/ECNTRL TX. BY LATE SATURDAY...ENOUGH DRIER AIR SHOULD MIX FAR ENOUGH SSW SUCH THAT ANY ISOLATED CONVECTION SATURDAY NIGHT/SUNDAY SHOULD REMAIN S OF THE REGION OVER SE TX/SRN LA. SLIGHTLY COOLER BUT DRIER AIR WILL FOLLOW THE FROPA THIS WEEKEND...BEFORE THE BNDRY SLOWLY BEGINS TO RETREAT BACK N EARLY NEXT WEEK. THIS WILL COME AS ELEVATED MOISTURE FROM A TROPICAL WAVE /OR POTENTIAL TROPICAL DEPRESSION OR STORM/ MAY BEGIN TO INCREASE FROM THE SW AROUND THE BACKSIDE OF THE UPPER RIDGE ONCE IT SHIFTS SE INTO THE GULF COAST STATES. THE GFS HAS ALSO BACKED OFF ON QPF AS WELL...COINCIDENT WITH THE CURRENT AND EARLIER RUNS OF THE ECMWF/CANADIAN...AS OVERALL FORCING REMAINS WEAK. HAVE TAPERED POPS DOWN TO SLIGHT CHANCE MONDAY AND TUESDAY EVEN AS THE SFC BNDRY CONTINUES TO MIX BACK N. RIDGING OVER THE SE CONUS/GULF COAST STATES LOOKS TO PERSIST THROUGHOUT MUCH OF NEXT WEEK...WITH THE ECMWF HINTING AT THE RIDGE FLATTENING BY NEXT WEEKEND /AND TWO DAYS LATER THAN WHAT WAS INDICATED TUESDAY/ AS A LARGE TROUGH BEGINS TO DIG SE ACROSS THE ROCKIES/PLAINS STATES. HAVE MAINTAINED ABOVE NORMAL TEMPS THROUGHOUT THE REMAINDER OF THE EXTENDED. PRELIMS TO FOLLOW BELOW... 15 && .AVIATION...
