Late this afternoon and evening, northwesterly winds aloft carried widely scattered thunderstorms southeastward from the central Texas Panhandle. One of these storms became a supercell and tracked southeast into western Briscoe County producing large hail up to golfball size at times.

The episode as NWS LUB wrote it up.
Late this afternoon and evening, northwesterly winds aloft carried widely scattered thunderstorms southeastward from the central Texas Panhandle. One of these storms became a supercell and tracked southeast into western Briscoe County producing large hail up to golfball size at times. Farther west and later in the evening, a downburst from a severe multicellular storm destroyed a barn and overturned a center-pivot irrigation system near Lakeview in southwest Swisher County.

NWS Lubbock, TX wrote its last area forecast discussion before the first event at Jun 1, 5:54 PM CST, 1 minute earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LUBBOCK TX 654 PM CDT FRI JUN 1 2012 .UPDATE... BULK OF SHORT-TERM SOLUTIONS DEVELOP A CONVECTIVE SYSTEM DROPPING SOUTH-SOUTHEAST THROUGH MUCH OF THE SOUTH PLAINS AND ROLLING PLAINS AREAS THIS EVENING. STORMS CURRENTLY ON THE VERGE OF ENTERING OUR NORTHERN ZONES. A SEVERE THUNDERSTORM WATCH HAS BEEN ISSUED UNTIL MIDNIGHT. WE HAVE BEEFED UP THUNDER CHANCES ESPECIALLY NORTHERN AND EASTERN ZONES FOR THIS EVENING. RMCQUEEN && .AVIATION... THUNDERSTORMS NORTH OF KCDS WILL BEGIN TO AFFECT THE TERMINAL SHORTLY WITH MORE WIDESPREAD ACTIVITY EXPECTED SHORTLY THEREAFTER. LATER THIS EVENING...THESE SAME STORMS MAY MOVE FAR ENOUGH SOUTH TO AFFECT THE KLBB TERMINAL BUT CONFIDENCE IS NOT HIGH AT THE MOMENT IN THIS OCCURRENCE. WILL THEREFORE LEAVE ANY MENTION OF THUNDERSTORMS OUT OF THE KLBB TAF. WINDS WILL INCREASE OUT OF THE SOUTH AGAIN SATURDAY AFTERNOON KEEPING LOW LEVEL MOISTURE IN THE REGION. ANOTHER CHANCE OF THUNDER WILL OCCUR AT EITHER TAF SITE AGAIN TOMORROW BUT THIS ACTIVITY IS NOT EXPECTED UNTIL AFTER 03/00Z. && .PREV DISCUSSION... /ISSUED 319 PM CDT FRI JUN 1 2012/ SHORT TERM... FORECAST FOCUSED AROUND THUNDERSTORM CHANCES TONIGHT AND AGAIN SATURDAY...WITH THE PROSPECTS OF SEVERE STORMS /FAVORING THE NORTHERN ZONES/ THIS EVENING AND AGAIN ON SATURDAY. DECENT LOW-LEVEL MOISTURE HAS NOW RETURNED TO THE ENTIRE FA...AS DEWPOINT HAVE RISEN INTO THE LOWER TO MIDDLE 50S. IN ADDITION...TEMPERATURES HAVE CLIMBED WELL INTO THE 80S YIELDING MLCAPE AOA 1000 J/KG FOR ALL BUT THE EXTREME EASTERN ZONES. HOWEVER...SOME CIN REMAINED IN PLACE AS OF THE 19Z OA FROM SPC...AND THIS IS REFLECTED IN THE BENIGN CU FIELD THAT HAS DEVELOPED THUS FAR ACROSS THE CAPROCK INTO THE SOUTHERN TEXAS PANHANDLE. SOME WEAK SFC CONVERGENCE WAS NOTED THROUGH THE EASTERN TX PANHANDLE AS WELL AS ACROSS THE OK PANHANDLE. IT REMAINS UNCERTAIN IF THE CLOSER AREA OF CONVERGENCE WILL RESULT IN CI...BUT IF IT DOES...MODEST NORTHWEST FLOW ALOFT WILL CARRY THE CONVECTION INTO THE NORTHEAST ZONES LATE THIS AFTERNOON OR EARLY THIS EVENING. THE COMBINATION OF SHEAR AND INSTABILITY WILL SUPPORT SEVERE CONVECTION /INCLUDING SUPERCELLS/ CAPABLE OF LARGE HAIL AND DAMAGING WINDS. OF GREATER CONFIDENCE IS IN ACTIVITY...ALREADY DEVELOPING ACROSS THE OK PANHANDLE...CONTINUING TO EXPAND /PERHAPS INTO A SMALL MCS/ AS IT TRACKS SOUTH-SOUTHEASTWARD. THIS ACTIVITY COULD THREATEN OUR NORTHERN ZONES BY 2-3Z...THOUGH WANING INSTABILITY WITH TIME LEAVE THE SOUTHWARD EXTEND OF THE CONVECTIVE PUSH SOMEWHAT IN QUESTION. THEREFORE...HAVE TAPERED EVENING POPS FROM AROUND 60 PERCENT NORTHEAST ZONES TO 15 PERCENT ACROSS THE SOUTHWEST ZONES. INCREASING SOUTHERLY LLJ TONIGHT COULD KEEP SOME ELEVATED ACTIVITY GOING OVERNIGHT /FAVORING THE NORTHEAST ZONES/...WHERE CHANCE POPS HAVE BEEN MAINTAINED AFTER 6Z. NORTHWESTERLY FLOW ALOFT WILL BACK TO QUASI-ZONAL BY LATE SATURDAY AS A DISTURBANCE EMERGES ACROSS THE CENTRAL HIGH PLAINS AND DRIVES ANOTHER ROUND OF CONVECTION. AT THE SFC...A RESIDUAL BOUNDARY FROM TONIGHT/S STORMS WILL LIKELY BE IN OR NEAR THE NORTHERN ZONES AND COULD BE THE FOCUS FOR ADDITIONAL CI SATURDAY AFTERNOON...THOUGH THE EXACT LOCATION IS SUBJECT TO CHANGE DEPENDING ON HOW STORMS PLAY OUT TONIGHT. NORTH OF THE BAROCLINIC BOUNDARY BACKED FLOW AND STRONG INSTABILITY WILL DEVELOP...SUPPORTIVE OF ANOTHER ROUND OF SEVERE WEATHER. FURTHER SOUTH...CONVERGENCE ALONG A SFC TROUGH EXTENDING SOUTHWARD FROM A SFC LOW ACROSS EAST-CENTRAL NM COULD YIELD ISOLATED/SCATTERED HIGH BASED STORMS. HENCE...HAVE INCREASED POPS TO CHANCE CATEGORY ACROSS THE NW/N ZONES TOMORROW AFTERNOON. LOWS TONIGHT WILL BE PRIMARILY IN THE 60S...WITH HIGHS TOMORROW GENERALLY IN THE 90S. LONG TERM... ONGOING PRECIP SATURDAY AFTN INTO SATURDAY EVENING WILL CONTINUE TO JUSTIFY CHC POPS ACROSS THE NRN ZONES BEFORE DISSIPATING BY LATE EVENING. UPPER RIDGE THEN PROGGED TO BUILD OVER THE PLAINS BY SUNDAY...ALTHOUGH LOOKING LIKE IT WILL NOT YET BE STRONG TO SHUT OFF PRECIPITATION SUNDAY WITH 12Z MODEL RUNS CONTINUING TO SHOW POTENTIAL FOR TSRA TO DEVELOP ALONG THE DRYLINE LATE IN THE DAY. BEYOND SUNDAY MODELS BEGIN TO HAVE PROBLEMS. THE FIRST IS WITH THE STRENGTH AND DURATION OF THE RIDGE AS THE GFS KEEPS RIDGING IN PLACE THROUGH THE WEEK WHILE THE ECMWF FLATTENS THE RIDGE WITH A SIGNIFICANT SHORT WAVE TROUGH THAT IS PROGGED TO MOVE ACROSS THE GREAT BASIN. DEEPER WESTERLY FLOW WITH THAT SCENARIO MAY KICK THE DRYLINE PRETTY FAR TO THE EAST...PARTICULARLY BY WEDNESDAY. SECOND ISSUE IS THE AMOUNT OF MOISTURE TRAPPED IN THE RIDGE...BUT MORE IMPORTANTLY ANY WEAKNESSES THAT GET CAUGHT IN THE RIDGE. THE GFS WHICH PREVIOUSLY WAS ATTEMPTING TO BRING THE CURRENT BAJA LOW OVER THE AREA KEEPS THAT FEATURE SOUTH BUT DOES BRING A LOW INTO THE AREA FROM THE NW WITH SOME CONVECTION MONDAY NIGHT THEN KEEPS IT TRAPPED AND AIDING PRECIP GENERATION THROUGH THE WEEK. THE SOURCE OF THIS LOW APPEARS TO BE CONVECTIVE AND MAY BE CONVECTIVE FEEDBACK IN THE MODEL THAT THEN IS MAINTAINED BY THE MODEL IN AREA OF WEAK MID LEVEL FLOW. FOR NOW THIS SOLUTION SEEMS NEBULOUS AND AN OUTLIER. THIRD ISSUE IS THE POTENTIAL FOR A COLD FRONT TO MOVE INTO THE AREA IN A BACKDOOR FASHION THEN HANG ON ACROSS THE AREA FOR SEVERAL DAYS. BOTH THE GFS AND ECMWF SHOW SOMETHING LIKE THIS OCCURRING ALTHOUGH THE TIMING DIFFERS. BIG QUESTION WITH THIS POSSIBILITY IS THE RIDGE AND ITS STRENGTH. AS A RESULT COULD PUT AT LEAST SLIGHT CHANCE POPS IN AREAWIDE EACH DAY OF THE WEEK. NOT SURE THAT IS THE WAY TO GO AT THIS POINT GIVEN THE SEVERAL AREAS OF UNCERTAINTY SUMMARIZED ABOVE. FOR NOW NO SIG CHANGE TO THE FCST BEYOND SUNDAY FAVORING 00Z MEXMOS OVER 12Z UNTIL A MORE DISTINCT TREND CAN BE OBSERVED. && .PRELIMINARY POINT TEMPS/POPS...

A WEAK FRONTAL BOUNDARY WILL CONTINUE TO EDGE INTO THE NORTHWESTERN PANHANDLE. THIS WILL BE THE INITIAL FOCUS FOR STRONG AND SEVERE THUNDERSTORM DEVELOPMENT. NORTHWESTERLY WINDS ALOFT WILL CARRY THESE STORMS OUT OF THE PANHANDLE INTO GENERALLY THE EXTREME SOUTHEASTERN PANHANDLE...NORTHEASTERN SOUTH PLAINS...AND NORTHERN ROLLING PLAINS...WITH SOME SOUTHWESTERN DEVELOPMENT LATE THIS EVENING. GIVEN MODERATE TO HIGH INSTABILITY THE PRIMARY THREAT WILL BE LARGE HAIL OF UP TO GOLF BALL SIZE OR LARGER...AND TO A LESSER EXTENT WINDS UP TO 60 MPH. .DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY A FEW STRONG TO SEVERE THUNDERSTORMS MAY MOVE FROM NORTHEASTERN NEW MEXICO INTO THE EXTREME SOUTHEASTERN TEXAS PANHANDLE AND NORTHWESTERN SOUTH PLAINS LATE ON SATURDAY. .SPOTTER INFORMATION STATEMENT... SPOTTER ACTIVATION MAY BECOME NECESSARY LATER TODAY.
The Amarillo radar (KAMA), 68 km away, was scanning. The volume nearest the first event began at 23:55 UTC.
1 hail, 1 thunderstorm wind. Local standard time, as filed.
A local official estimated golfball size hail eight miles north of Mackenzie Reservoir. No damage was reported.
A partially upkept barn about 11 miles west-southwest of Tulia was destroyed by downburst winds from a severe thunderstorm. About one quarter of the structure remained intact. An NWS storm survey found debris from the barn carried at least one mile southward and fanned outward in a divergent pattern up to 500 yards wide. This pattern of debris is a distinct characteristic of a downburst. In addition, a center pivot on the southwest corner of FM 928 and CR 3 about two miles south-southwest of the barn was flipped over. Winds were determined to be at least 90 mph.
