The episode as NWS LUB wrote it up.
Scattered pulse storms developed this afternoon over the southern Rolling Plains in a hot and rather dry environment. High cloud bases around 12,000 feet created sufficient downdraft CAPE for downbursts; one of which was measured to 78 mph northeast of Aspermont. This same downburst traveled southwest and created varying degrees of damage to carports, power lines and trees in Aspermont before dissipating southwest of town.

AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LUBBOCK TX 331 PM CDT FRI AUG 14 2015 .SHORT TERM... THE UA RIDGE CENTERED ACROSS NWRN NM LATE THIS AFTN...WILL CONTINUE TO MIGRATE NW TOWARDS THE FOUR-CORNERS THRU SATURDAY. THE LOCATION OF THE SAID UA RIDGE HAS RESULTED IN NRLY FLOW ALOFT...WITH WHAT APPEARS TO BE A FEW WEAK EMBEDDED IMPULSES ROUNDING THE ERN PERIPHERY OF THE RIDGE...EVIDENT BY SCATTERED CONVECTION ACROSS ERN TX AND THICKENING MID-HIGH LEVEL CLOUDINESS. LATE LAST NIGHT/EARLY THIS MORNING...CONVECTION ACROSS THE HIGHER TERRAIN OF SE CO AND THE TX PANHANDLE GENERATED AN OUTFLOW BOUNDARY WHICH SAGGED ACROSS MAINLY THE SOUTH PLAINS EARLIER THIS MORNING. THIS PROMOTED N-NE LIGHT SFC WINDS...AS WELL AS SEVERAL AREAS EXPERIENCING LIGHT AND VARIABLE WINDS PER 20Z METARS. ACROSS THE FAR ERN ZONES...SRLY SFC FLOW ENSUED. THIS SFC TROUGH/CHANGE IN WIND DIRECTION ALONG WITH THE MID-UPPER LEVEL MOISTENING...WILL BE A FOCUS FOR ISOLATED-SCATTERED CONVECTION THIS AFTN INTO THE EVENING. IN FACT...LIGHT RADAR ECHOES HAVE DEVELOPED ACROSS THE FAR SW TX PANHANDLE AND NW SOUTH PLAINS. THE TTU WRF APPEARS TO HAVE A DECENT HANDLE ON THE ON-GOING PRECIP AND AS SUCH...ADDITIONAL DEVELOPMENT IS EXPECTED ON THE CAPROCK AND PERHAPS TO ACROSS PORTIONS OF THE ROLLING PLAINS THRU THIS EVENING...WHILST SLOWLY DRIFTING SWRD. THE NAM IS SIMILAR...WITH THE EXCEPTION OF IT SHOWING PRECIP TO BE BIT MORE SCATTERED ACROSS THE ROLLING PLAINS. THUS...PRECIP COULD DEVELOP JUST ABOUT ANYWHERE. IF THIS INDEED COMES INTO FRUITION...THIS ACTIVITY WILL BE WORKING WITH 700-1500 J/KG OF MID-LEVEL CAPE...RELATIVELY WEAK STORM MOTION /5-10 KTS/ AND PWATS OF 1.30-1.80 INCHES. THIS SUGGESTS A FEW STORMS APPROACHING STRONG LEVELS WITH SMALL HAIL AND BRIEF GUSTY WINDS BEING THE PRIMARY THREATS...AS WELL AS LOCALIZED MODERATE RAINFALL. OVERNIGHT...MODELS HINT AT A LULL IN PRECIP BUT COULD SEE SOME RE- DEVELOPMENT THROUGHOUT THE DAY SATURDAY ACROSS THE FAR WRN ZONES /NEAREST TO A SFC TROUGH/ AND ACROSS THE FAR ERN ZONES /COINCIDING WITH BEST UPSLOPE AND THUS BEST PWATS/. OVERNIGHT LOWS WILL RANGE FROM THE MIDDLE 60S ACROSS THE FAR SW TX PANHANDLE TO THE 70S ACROSS THE FAR ROLLING PLAINS. HIGHS SATURDAY WILL BE CLOSER TO SEASONAL NORMS GIVEN THE UA RIDGE NOT BEING DIRECTLY OVERHEAD /UPPER 80S TO LOWER 90S ON THE CAPROCK TO LOWER TO MIDDLE 90S OFF THE CAPROCK/. .LONG TERM... AS UPPER RIDGE CONTINUES VERY SLOW SHIFT BACK TO THE WEST...AND FLATTENS...THE MONSOONAL FLOW WRAPPING AROUND THE DIFLUENT EASTERN PART OF THE RIDGE WILL SLOWLY THIN. WE WILL MAINTAIN LOW MENTION OF THUNDER ALONG WESTERN BORDER MAINLY SATURDAY EVENING THROUGH ABOUT MONDAY. MEANWHILE...A WAVE EMERGING THROUGH THE ROCKIES WILL TEND TO PULL REMAINING THINNED OUT MOISTURE PLUME BACK TO THE EAST BY TUESDAY AND EARLY WEDNESDAY. SOLUTIONS HAVE BEEN STRUGGLING WITH THE AMPLITUDE AND TIMING OF THIS SYSTEM AND ALSO A POSSIBLE COLD FRONT AROUND TUESDAY NIGHT OR WEDNESDAY...AND WITH TODAYS RUN STILL WE ARE SEEING RELATIVELY POOR CONTINUITY. THE STRONGER AND SLOWER SOLUTIONS FAVOR THE BULK OF MOISTURE AND LIFT IMPACTING THE PANHANDLE AND PERHAPS OUR NORTHEAST ZONES...ALTHOUGH WITH ENOUGH BACKED FLOW WE MIGHT BRIEFLY PULL THE DEEPER MOISTURE ACROSS THE REGION TUESDAY NIGHT OR SO. BUT WE ARE RELUCTANT TO PUT TOO MUCH EMPHASIS ON PRECIPITATION CHANCES WITH SUCH A SYSTEM. SO WE WILL INDICATE LOW MENTION OF THUNDER MAINLY NORTHEAST TUESDAY NIGHT WITH ONLY A SLIGHT DOWNWARD TEMPERATURE TREND FOR MID WEEK...AND DISREGARD OTHER POSSIBILITIES UNTIL SOLUTIONS SHOW CLEARER TRENDS. LATER IN THE WEEK WE ALSO ARE NOT SEEING VERY CLEAR AGREEMENT ON POSSIBLE RETURN OF DEEP LAYERED MOISTURE. WE OPT TO RETAIN A LOW MENTION LATE WEEK BUT TREND DRIER HEADING INTO NEXT WEEKEND. WITH HEIGHTS ALOFT LOWERED OVERALL...TEMPERATURES SHOULD NOT PROVE TOO EXTREME IN THIS UPCOMING PATTERN. RMCQUEEN && .PRELIMINARY POINT TEMPS/POPS...
