The episode as NWS FWD wrote it up.
Scattered thunderstorms developed along a subtle surface boundary situated across the southern counties of North Texas. These storms produced wind damage. Later that evening, a complex of storms over eastern Oklahoma pushed south, producing more wind damage as it crossed the Red River into Lamar County.

NWS Fort Worth, TX wrote its last area forecast discussion before the first event at Aug 8, 8:59 AM CST, 3 hours 41 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE FORT WORTH TX 959 AM CDT WED AUG 8 2012 .UPDATE... SHORT-TERM...HIGH RESOLUTION MODELS INDICATE THAT A CONVECTIVELY ACTIVE PERIOD WILL CONTINUE THROUGH THE DAY ACROSS MUCH OF THE REGION. THE LARGE OUTFLOW BOUNDARY THAT MOVED THROUGH OVERNIGHT APPEARS TO HAVE COMPLETELY DISSIPATED BUT ONGOING CONVECTION THIS MORNING HAS ALREADY PRODUCED SEVERAL OUTFLOW BOUNDARIES WITH WINDS OF 20 TO 30 MPH BEHIND EACH BOUNDARY. THE LARGEST BOUNDARY THIS MORNING CURRENTLY STRETCHES FROM NEAR CARBON TO FORT WORTH TO EAST OF SHERMAN. THIS BOUNDARY IS QUICKLY MOVING SOUTH AND SOUTHEAST. THE REGION CONTINUES UNDER DIVERGENT NORTH FLOW ALOFT WITH SEVERAL WEAK SHORTWAVES MOVING ACROSS THE REGION FROM NORTH TO SOUTH. THE COMBINATION OF HEATING...ADDED LIFT FROM THE SHORTWAVES...AND THE SURFACE BOUNDARIES ARE EXPECTED TO KEEP THE SHOWER AND THUNDERSTORM ACTIVITY GOING INTO AT LEAST THE EVENING HOURS WITH SOME ACTIVITY LIKELY TO OCCUR OVERNIGHT AS WELL. THE 12Z FWD SOUNDING THIS MORNING INDICATES HIGHER PWATS IN PLACE WITH A MORE MOIST ENVIRONMENT ABOVE THE INVERSION AROUND 770 MB. WITH SOME DIURNALLY-DRIVEN DRYING OF THE LOWER LEVELS EXPECTED TODAY...THIS INCREASES THE THREAT FOR DAMAGING DOWNBURST WINDS WITH ANY STRONGER STORMS THAT DEVELOP THIS AFTERNOON AND EVENING. THIS AFTERNOON...THE MAIN FOCUS FOR CONVECTION COULD SHIFT TO AREAS MAINLY SOUTH OF INTERSTATE 20 WHERE THIS MORNING/S OUTFLOW BOUNDARIES WILL LIKELY RESIDE. THIS IS A TREND THAT THE SHORT- TERM...HIGH RESOLUTION MODELS ARE ALSO INDICATING. HAVE INCREASED POPS ACROSS THE REGION FOR TODAY AND THIS EVENING TO 30 TO 40 PERCENT. TEMPERATURES WILL BE TRICKY DUE TO THE ONGOING RAIN THIS MORNING BUT DID LOWER HIGH TEMPERATURES A BIT ACROSS MAINLY THE NORTHWEST HALF OF THE CWA WHERE RAIN COOLED AIR AND DENSE CLOUD COVER ARE OCCURRING THIS MORNING. 82/JLD && .AVIATION... THE ONLY AVIATION WEATHER CONCERN THROUGH SUNRISE THURSDAY WILL BE THE POTENTIAL FOR SCATTERED CONVECTION. MOST OF THIS MORNINGS ACTIVITY SHOULD REMAIN WELL TO THE EAST OR WEST OF ANY OF THE TAF SITES. MORNING CONVECTION SHOULD WEAKEN SHORTLY AFTER SUNRISE WITH ADDITIONAL SHOWERS AND STORMS EXPECTED THIS AFTERNOON AND EVENING. ALTHOUGH COVERAGE MAY BE SLIGHTLY BETTER THAN THIS MORNINGS ACTIVITY...IT WILL STILL BE TOO LIMITED TO MENTION IN ANY OF THE TAFS. OTHERWISE...EXPECT VFR CONDITIONS WITH SCATTERED TO BROKEN...MAINLY MID AND UPPER LEVEL CLOUDS. WINDS WILL BE LIGHT BUT GENERALLY FROM THE SOUTH THIS MORNING. SOUTHERLY WINDS SHOULD INCREASE BETWEEN 8 AND 11 KNOTS BY MIDDAY. A COLD FRONT WILL APPROACH THE METROPLEX TAF SITES BEFORE 18Z THURSDAY SO WILL TURN THE WINDS TO THE WEST NORTHWEST AT THE END OF THE DFW TAF PERIOD. 79 && .PREV DISCUSSION... /ISSUED 325 AM CDT WED AUG 8 2012/ A HIGH AMPLITUDE RIDGE CONTINUES TO SPIRAL ANTICYCLONICALLY OVER THE FOUR CORNERS WHILE A LONGWAVE TROUGH REMAINS ENTRENCHED OVER THE EAST COAST. THE RESULTING NORTH FLOW OVER THE REGION WILL CONTINUE TO SEND A SERIES OF WEAK DISTURBANCES SOUTHWARD FROM THE PLAINS INTO NORTH TEXAS DURING THE NEXT FEW DAYS. ONE SUCH FEATURE WAS RESPONSIBLE FOR A PERSISTENT AREA OF SHOWERS AND THUNDERSTORMS WHICH CONTINUES TO PUSH SOUTHWARD INTO THE NORTHWESTERN COUNTIES OF THE CWA EARLY THIS MORNING. ADDITIONAL DEVELOPMENT DURING THE NEXT SEVERAL HOURS WILL LIKELY BE DRIVEN BY MESOSCALE PROCESSES. A WELL-DEFINED OUTFLOW BOUNDARY HAD ADVANCED SOUTHWARD TO A BOWIE-BRECKENRIDGE LINE BY 3 AM AND SHOULD PROVIDE FOCUS FOR NEW SHOWER AND THUNDERSTORM DEVELOPMENT THROUGH THE EARLY TO MID MORNING HOURS. MOST SHOWERS AND STORMS SHOULD REMAIN WEST OF I-35/35W CORRIDOR DURING THE MORNING HOURS. ACTIVITY WILL LIKELY EXHIBIT A WEAKENING TREND LATER THIS MORNING DURING TYPICAL NOCTURNAL MCS WEAKENING PERIOD. SURFACE HEATING AND DESTABILIZATION SHOULD THEN LEAD TO MORE SHOWER AND THUNDERSTORM DEVELOPMENT AGAIN THIS AFTERNOON WITH ACTIVITY FOCUSED ALONG LINGERING MESOSCALE BOUNDARIES. THE HIGHEST POPS WILL BE OVER THE WESTERN COUNTIES THIS MORNING BASED MAINLY ON RADAR TRENDS...BUT WILL BROAD-BRUSH SLIGHT CHANCE POPS ACROSS THE ENTIRE REGION FOR THE AFTERNOON PERIOD. A STRONGER SHORTWAVE IS PROGGED TO DIVE SOUTH-SOUTHEASTWARD FROM THE NORTHERN PLAINS INTO THE MS VALLEY TONIGHT THROUGH THURSDAY...EFFECTIVELY DEEPENING THE EAST COAST TROUGH. THIS WILL FORCE A COLD FRONT SOUTHWARD INTO NORTH TEXAS BY THURSDAY AFTERNOON. THE FRONT WILL WORK ITS WAY SOUTH THROUGH THE AREA THURSDAY NIGHT INTO FRIDAY. THE BOUNDARY SHOULD HAVE JUST ENOUGH PUSH TO MAKE IT THROUGH THE MAJORITY OF THE REGION BY LATE FRIDAY. WILL CONTINUE THE SLIGHT CHANCE POPS AHEAD OF AND ALONG THE FRONT THURSDAY AND FRIDAY...WITH DRIER AIR BRINGING AN END TO SIGNIFICANT RAIN CHANCES BY SATURDAY. TEMPERATURES WILL ALSO BE SLIGHTLY COOLER BEHIND THE FRONT THIS WEEKEND...BUT STILL ON THE WARM SIDE AS THE RIDGE OVER THE ROCKIES EXPANDS SOUTHEASTWARD ACROSS TEXAS TO THE GULF. 30 && .PRELIMINARY POINT TEMPS/POPS...
