NWS Lubbock, TX wrote its last area forecast discussion before the first event at Aug 4, 2:02 PM CST, 2 hours 11 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LUBBOCK TX 302 PM CDT WED AUG 4 2010 .SHORT TERM... THE MAIN CONCERN FOR THE SHORT TERM PERIOD WILL BE PRECIPITATION CHANCES TODAY AND THURSDAY. A CURRENT SURFACE ANALYSIS SHOWS THAT A WEAK COLD FRONT HAS STALLED OUT ACROSS THE SOUTHERN TEXAS PANHANDLE THIS AFTERNOON. THIS BOUNDARY IS EXPECTED TO BE THE FOCUS FOR ANY CONVECTION THAT MAY DEVELOP ACROSS THE NORTHERN ZONES LATER THIS AFTERNOON AND EVENING. THE NAM-12 IN PARTICULAR GENERATES A STRONG CONVECTIVE SIGNAL ACROSS THE SOUTHERN PANHANDLE COUNTIES THIS EVENING...WHILE THE GFS...HRRR...AND WRF HAVE GENERALLY KEPT MOST OF THE ACTIVITY NORTH OF THE AREA. GENERALLY AGREE WITH THIS THINKING GIVEN THAT THE BEST INSTABILITY AND SHEAR VALUES ARE LOCATED ACROSS THE PANHANDLE. HOWEVER...GIVEN THE LOCATION OF THE AFOREMENTIONED BOUNDARY...CERTAINLY CANNOT RULE OUT ISOLATED SHOWERS AND STORMS DEVELOPING AND DRIFTING INTO THE NORTHERN ZONES THIS EVENING. THEREFORE...HAVE MAINTAINED A LOW-END MENTION OF POPS THROUGH 06Z IN THAT AREA. FOR THURSDAY...AN UPPER-LEVEL RIDGE WILL CONTINUE TO RETROGRADE WEST TOWARD THE SOUTHERN PLAINS. HOWEVER...A WEAK SHORTWAVE TROUGH IS PROGGED TO ROUND THIS RIDGE LATE TONIGHT AND BUMP THE AFOREMENTIONED COLD FRONT FURTHER SOUTH INTO THE AREA BY THURSDAY MORNING. AT THIS TIME...THE EXACT ORIENTATION OF THE FRONT IS UNCERTAIN...BUT THE NAM APPEARS TO BE MOST AGGRESSIVE...PUSHING THE FRONT INTO THE SOUTHERN ZONES...BEFORE RETREATING IT SOME BY THE AFTERNOON. THE GFS GENERALLY KEEPS THE FRONT ACROSS THE NORTHERN ZONES...BEFORE RETREATING IT NORTH INTO THE PANHANDLES. THUS...A DISCREPANCY IN PRECIP CHANCES EXISTS ACROSS THE AREA AS THE NAM SHOWS A CONVECTIVE SIGNAL FURTHER SOUTH THAN THE GFS DOES. FOR NOW...HAVE KEPT MENTIONABLE POPS ACROSS THE SOUTHERN PANHANDLE AND NORTHERN SOUTH PLAINS THROUGH 00Z. HOWEVER...BASED ON THE LATEST TRENDS THIS MAY NEED TO BE READJUSTED LATER. ALSO...GIVEN THE PRESENCE OF A BOUNDARY SOMEWHERE ACROSS THE AREA AND POTENTIALLY HIGHER INSTABILITY VALUES...HAVE SLIGHTLY HIGHER CONFIDENCE OF RAIN CHANCES FOR TOMORROW IN THE LUB CWA. STILL...GIVEN FAIRLY WEAK WIND SHEAR...DO NOT EXPECT MUCH ORGANIZATION WITH ANY STORMS THAT DO FORM. OTHERWISE...GIVEN THE POTENTIAL FOR MORE CLOUD COVER... CONVECTION...AND PROGGED LOWER THICKNESS VALUES...HAVE OPTED TO BUMP HIGH TEMPERATURES DOWN A COUPLE OF DEGREES AREAWIDE. && .LONG TERM... ABOVE AVERAGE TEMPERATURES ARE THE THEME THROUGH THE EXTENDED AS AN UPPER LEVEL HIGH RESIDES NEARBY. THIS UPPER RIDGE IS FORECAST TO BE CENTERED ACROSS TX/NM THROUGH FRI/SAT BEFORE SLOWLY TRANSLATING NORTHEASTWARD AND AMPLIFYING ACROSS THE CENTRAL MISSISSIPPI RIVER VALLEY FOR THE EARLY TO MIDDLE PARTS OF NEXT WEEK AS A WESTERN CONUS TROUGH EDGES SLOWLY INLAND. THE MAIN IMPACT WITH THIS RIDGE WILL BE THE TOASTY TEMPERATURES. HOWEVER...THE RESIDUAL FRONT/BOUNDARY ALLUDED TO IN THE SHORT TERM WILL LIKE BE LAYING SOMEWHERE IN THE AREA FRIDAY...AND ALTHOUGH IT WILL BE DECAYING...MODERATE MID-LEVEL MOISTURE AND THE FOCUS ON THE BOUNDARY MAY BE ENOUGH TO SUPPORT ISOLATED AFTERNOON STORMS...FAVORING THE NE ZONES. THUS...HAVE BUMPED POPS UP TO MINIMAL MENTIONABLE LEVELS FRIDAY AFTERNOON. PROGGED SHEAR AND INSTABILITY ARE RATHER WEAK...SO ORGANIZATION SHOULD BE LIMITED...THOUGH THE INVERTED-V PROFILES SUGGEST A LOW END WIND THREAT IF ANY HEAVIER CORE DEVELOPS. THE LOW-LEVEL FOCUS SHOULD FURTHER DIMINISH INTO THE WEEKEND...BUT SEVERAL MEDIUM RANGE MODELS DO CONTINUE TO GENERATE LIGHT QPF EACH AFTN AS SOME MID-LEVEL MOISTURE REMAINS TRAPPED WITHIN THE RIDGE. THUS...CAN NOT COMPLETELY RULE OUT A STRAY SHOWER/STORM OVER THE WEEKEND...BUT WITHOUT A CLEAR FOCUS AND RIDGING ALOFT...CHANCES/COVERAGE APPEAR NO BETTER THAN ABOUT 10 PERCENT. BY THE EARLY TO MIDDLE PARTS OF NEXT WEEK...ATTENTION WILL TURN TO THE MONSOONAL PLUME OF MOISTURE IN NM WHICH WILL SHIFT EASTWARD TOWARD THE NM/TX STATE LINE. THIS COULD PROVIDE ENOUGH SUPPORT FOR AFTN/EVNG STORMS TO THREATEN THE EXTREME WESTERN/NORTHWESTERN ZONES...BUT THE MOISTURE PLUME IS ALSO PROGGED TO THIN/WEAKEN AND IT IS UNCLEAR WHETHER THE SLIGHT PATTERN SHIFT WILL BE ENOUGH TO WARRANT A THUNDER MENTION ACROSS THE WEST.
