Triple digit temperatures, low surface dewpoints, drier air in the mid levels of the atmosphere and a disturbance aloft were the ingredients needed to get scattered thunderstorms to develop across Northeast Texas during the late afternoon hours of September 1st. Once these thunderstorms collapsed, they became prolific wind producers with damaging downburst winds.

Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.
The episode as NWS SHV wrote it up.

NWS Shreveport, LA wrote its last area forecast discussion before the first event at Sep 1, 3:24 PM CST, 45 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SHREVEPORT LA 424 PM CDT SUN SEP 1 2013 .DISCUSSION... CURRENT LOCATION OF COLD FRONT IS ROUGHLY MARKED BY A SHIELD OF MID LEVEL CLOUDS STRETCHING FROM ERN NM EWD ACROSS THE RED RIVER BETWEEN OK/TX...NEWD TO NEAR KMLC...AND INTO NRN AR/SE MO. SCT SHWRS/TSTMS HAVE BEEN ONGOING FOR MUCH OF THE DAY ALONG THE FRONT. THE EROSION OF A WEAK CAP...INSTABILITY FROM SFC TEMPS NEAR OR ABOVE 100 DEGREES F...AND SOME ENHANCED LIFT FROM A SHORTWAVE TROUGH JUST NORTH OF HOUSTON TX...HAS LED TO THE DEVELOPMENT OF SCT CONVECTION ROUGHLY PARALLEL TO I-30 FROM KPSN NEWD TO KMEM. CONVECTIVE COVERAGE SHOULD BE GREATER THAN EVENING COMPARED TO THE PREVIOUS 24 HOURS GIVEN THE WEAK CAP AND THE APPROACH OF THE COLD FRONT. DO NOT CURRENTLY ANTICIPATE AN ORGANIZED TSTM COMPLEX FROM THIS ACTIVITY. HOWEVER...THERE IS THE POTENTIAL FOR DAMAGING WINDS FROM DOWNBURSTS AS ROBUST UPDRAFTS COLLAPSE OR SHOULD ANY CELLS ORGANIZE INTO SMALL CLUSTERS SO ONE OR TWO ISOLATED SEVERE STORMS CANNOT BE RULED OUT. MUCH OF THE ACTIVITY THAT BEEN ONGOING IN OK FOR MUCH OF THE DAY HAS BEEN DUE TO A WEAK MCV WHICH IS WILL APPROACH THE CWA LATER TONIGHT IN THE NWLY FLOW. EVEN THOUGH MOST OF THE CONVECTIVE INTENSITY AND COVERAGE SHOULD DIMINISH LATER THIS EVENING...THE COLD FRONT AND THE MCV SHOULD HELP SUSTAIN A FEW SHWRS/TSTMS THROUGH THE OVERNIGHT HOURS. ANOTHER ROUND OF CONVECTION IS EXPECTED FOR MUCH OF MONDAY AS THE COLD FRONT STALLS NEAR I-20. ONCE AGAIN LITTLE IN THE WAY OF ORGANIZATION IS EXPECTED BUT A POTENTIAL FOR DAMAGING WINDS WILL STILL BE PRESENT. COLD FRONT SHOULD MOVE A BIT FARTHER SOUTH ON TUESDAY BEFORE FINALLY BECOMING DIFFUSE. WHAT IS LEFT OF THE LINGERING BOUNDARY WILL KEEP SLIGHT CHANCE POPS ACROSS AT LEAST PORTIONS OF DEEP E TX/CNTRL LA THROUGH THURSDAY...MAINLY DURING PEAK HEATING. HOWEVER...SUBSIDENCE FROM A SFC HIGH BUILDING INTO THE AREA FROM THE NE WILL BEGIN TO LIMIT RAIN CHANCES BY WEDNESDAY. GENERALLY DRY CONDITIONS SHOULD RETURN BY LATE WEDNESDAY BEFORE SLIGHT CHANCES FOR RAIN RETURN ONCE AGAIN DURING THE WEEKEND AS ANOTHER WEAK UPPER TROUGH MOVES SOUTH ACROSS THE CWA. THE RAIN CHANCES AND SLIGHTLY DRIER AND COOLER AIRMASS BEHIND THE FRONT SHOULD LIMIT THE POTENTIAL FOR TRIPLE DIGIT HEAT FOR MOST OF THE AREA THROUGH THE EXTENDED PERIODS. MAX TEMPS SHOULD FALL BACK INTO THE LOW TO MID 90S WITH THE WARMEST TEMPS ACROSS E TX SOUTH OF I-20. /09/ && .AVIATION... MOSTLY VFR FLIGHT CATEGORIES WILL PREVAIL THROUGH THE TERMINAL FORECAST PERIOD ENDING AT 03/00 UTC WITH THE EXCEPTION OF MVFR CEILING AND VISIBILITY RESTRICTION WITH ANY CONVECTION THAT DEVELOPS THIS AFTERNOON AND LINGERS INTO THE EVENING...AND AFTER A BREAK DURING THE MIDDLE PART OF THE EVENING...AGAIN DURING LABOR DAY. AN UPPER LEVEL LOW PRESSURE AREA OVER DEEP EAST AND SOUTHEAST TEXAS THIS AFTERNOON WILL CONTINUE TO RETROGRADE DOWN THE TEXAS COAST. AROUND THE NORTH AND NORTHWEST PERIPHERY OF THIS SYSTEM...ISOLATED CONVECTION WILL BE POSSIBLE ALONG AND NEAR THE INTERSTATE 30 CORRIDOR...AND DOWN AND ALONG TO INTERSTATE 20... WITH A WEAK TROUGH AXIS OVER SOUTHWEST ARKANSAS...SOUTHEAST OKLAHOMA...AND NORTHEAST TEXAS. WILL CONTINUE MENTION OF VCTS FOR THE KTXK...KTYR...AND KGGG TERMINALS DURING THE EVENING...AND WILL MAY INCLUDE MENTION FOR KSHV...KELD...AND KLFK...BUT WITH LOWER CONFIDENCE OF OCCURRENCE FOR KMLU. CLOUD COVER WILL INCREASE OVERNIGHT AND INTO MONDAY WITH THE MOVEMENT OF A FRONTAL BOUNDARY MOVING SOUTH ACROSS THE AREA NEARING THE INTERSTATE 30 CORRIDOR DURING THE MID TO LATE MORNING ON LABOR DAY AND POSSIBLY TOWARD INTERSTATE LATER IN THE DAY. BETTER CHANCE OF CONVECTION WILL ACCOMPANY THE BOUNDARY THROUGH MONDAY AFTERNOON AND NIGHT. WINDS WILL BE SOUTHWEST TO SOUTH 5 TO 10 KNOTS AND LOWERING PRIOR TO DAYBREAK...THEN MORE VARIABLE AHEAD OF FRONTAL BOUNDARY...BECOMING MORE WEST TO NORTHWEST WITH PASSAGE OF THE FRONT. /06/ && .PRELIMINARY POINT TEMPS/POPS...
