The episode as NWS LUB wrote it up.
A linear convective complex moved southeastward over portions of the southeastern Texas Panhandle during the late evening hours of the 18th. The complex displayed a bow-shaped radar reflectivity structure indicative of strong winds as it impacted portions of Hall and Childress Counties. A localized wind gust in excess of 60 mph was measured by the Texas Tech University West Texas Mesonet.

NWS Lubbock, TX wrote its last area forecast discussion before the first event at Aug 19, 5:32 PM CST, 4 hours 50 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LUBBOCK TX 632 PM CDT WED AUG 19 2009 .AVIATION... VFR CONDITIONS ARE EXPECTED TO PREVAIL THROUGHOUT THE TAF PERIOD WITH A COLD FRONT BEING THE ONLY MAJOR FACTOR. THUNDERSTORM ACTIVITY NEAR KCDS SEEMS LESS LIKELY FOR THIS EVENING WITH THE LATEST MODEL RUNS. HOWEVER...A SHARP COLD FRONT WILL MOVE THROUGH THE AREA AROUND DAYBREAK AT KCDS AND A FEW HOURS LATER AT KLBB. THIS WILL SHIFT WINDS QUICKLY TO THE NORTHEAST AROUND 12 TO 15 KNOTS. && .PREV DISCUSSION... /ISSUED 334 PM CDT WED AUG 19 2009/ SHORT TERM... MODELS ARE IN SOME AGREEMENT THAT A SHORTWAVE TROF OVER THE SW OK/E TX PNHDL WILL RESULT IN A MENTIONABLE CHANCE FOR POPS FOR THE NE ZONES. 12Z NAM KEEPS MOST QPF TRIMMING THE NERNMOST ZONES AND INTO THE SW OK COUNTIES FOR MUCH OF TONIGHT RESULTING IN ONLY SLIGHT CHANCE FOR POPS IN AND AROUND CHILDRESS. NW FLOW SHOULD MOVE THIS ACTIVITY OUT OF THE CWA BY THURSDAY MORNING. A FAIRLY SIGNIFICANT COLD FRONT WILL IMPACT THE CWA THURSDAY MORNING ROUGHLY AROUND 11-13Z BRINGING WITH IT SOME SUBSTANTIAL COOLING. GFS/NAM/ECWMF SOLUTIONS SEEM TO AGREE RATHER WELL ON THE TIMING OF THE COLD FRONT WITH MINOR FLUCTUATIONS IN TEMP RANGE. WINDS SHOULD VEER TO THE SOUTHWEST IN RESPONSE TO THE APPROACHING FRONT AND FURTHER RESULT IN A SHIFT TO NE WINDS AFTER ITS PASSAGE. HAVE INCREASED WINDS SLIGHTLY BEHIND THE FRONT WITH MODELS INDICATING 15-20KT SPEEDS LIKELY DUE TO MOMENTUM TRANSFER FROM 40KT PROGGED 850MB WINDS. BY 22-00Z INTENSE SURFACE HEATING SOUTH OF THE ADVANCING FRONT WILL LIKELY RESULT IN CLOUD DEVELOPMENT IN THE SOUTHERN ZONES AND A SLIGHT CHANCE FOR RAIN. HOWEVER MODELS ARE RELUCTANT TO EXTEND TOO MUCH QPF IN RESPONSE TO THE FRONT SO CONFIDENCE IS LOW ATTM. LONG TERM... THE MAIN CONCERN FOR THE EXTENDED FORECAST CONTINUES TO BE SHOWER AND THUNDERSTORM CHANCES THURSDAY NIGHT INTO THE WEEKEND ASSOCIATED WITH A SOUTHWARD MOVING COLD FRONT. MODELS CONTINUE TO SHOW THIS FRONT MOVING ACROSS THE LUB CWA ON THURSDAY AFTERNOON THROUGH THURSDAY NIGHT...BEFORE STALLING OUT ALONG THE INTERSTATE 20 CORRIDOR ON FRIDAY MORNING. WITH SUFFICIENT INSTABILITY AND A LIFTING MECHANISM IN PLACE...FEEL THAT SHOWERS AND STORMS MAY CONTINUE TO FORM/PERSIST OVERNIGHT ACROSS THE SOUTH PLAINS AS THE FRONT GRADUALLY PUSHES TO THE SOUTH. MODELS SEEM TO AGREE THAT THE FRONT WILL HAVE PASSED THROUGH THE SOUTHERN TEXAS PANHANDLE DURING THE AFTERNOON AND THEREFORE HAVE KEPT MENTIONABLE POPS ACROSS THE SOUTHERN HALF OF THE REGION OVERNIGHT. HOWEVER...THE EXACT TIMING OF THE FRONT REMAINS SOMEWHAT UNCERTAIN AND THUS CANNOT RULE OUT ANY STORMS FORMING ACROSS THE ENTIRE AREA THROUGH MID EVENING. WITH MODELS SHOWING THE FRONT STALLING OUT JUST TO THE SOUTH OF THE AREA ON FRIDAY...ISOLATED SHOWERS AND STORMS ARE CERTAINLY NOT OUT OF THE QUESTION FRIDAY AND SATURDAY EVENING AS THE FRONT SLOWLY RETREATS NORTHWARD. THE 12Z RUN OF THE NAM-12 ACTUALLY SHOWS THE POTENTIAL FOR MORE WIDESPREAD CONVECTION SATURDAY NIGHT ACROSS THE SOUTH PLAINS. ATTM...DO NOT HAVE ENOUGH CONFIDENCE TO ADD MENTIONABLE POPS IN THE SOUTHERN ZONES...BUT WILL CONTINUE TO MONITOR THE LATEST OBS AND MODEL TRENDS OVER THE NEXT COUPLE OF DAYS. A RIDGE OF HIGH PRESSURE WILL ALSO ATTEMPT TO BUILD OVERHEAD ACROSS THE REGION THIS WEEKEND THROUGH THE MIDDLE OF NEXT WEEK. TEMPERATURES SHOULD BE AROUND SEASONABLE LEVELS WITH DAYTIME HIGHS GENERALLY RANGING BETWEEN IN THE UPPER 80S TO MID 90S AND OVERNIGHT LOWS DROPPING INTO THE LOW TO UPPER 60S. A NORTHWESTERLY FLOW MAY BE POSSIBLE THIS WEEKEND...BUT THE WINDS ALOFT SHOULD GENERALLY MAINTAIN A MORE NORTHEASTERLY COMPONENT FOR MOST OF THE AFOREMENTIONED PERIOD...HELPING TO MAINTAIN DRY CONDITIONS. THUS WILL KEEP POPS BELOW MENTIONABLE LEVELS FOR NOW. && .PRELIMINARY POINT TEMPS/POPS...
