Area forecast discussion, Aug 24, 6:24 PM CDT, 1 hour 24 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LUBBOCK TX 624 PM CDT FRI AUG 24 2012 .AVIATION... EVEN WITH THE THREAT OF TSRA THIS EVENING...VFR CONDITIONS WILL PREVAIL. A SMALL AREA OF TSRA IS EXPECTED TO IMPACT LBB BEFORE 01Z WITH BRIEF WIND GUSTS UP TO 35 KNOTS. FARTHER EAST...SLIGHTLY GREATER INSTABILITY JUST OFF THE CAPROCK IS EXPECTED TO YIELD SCATTERED TSRA THROUGH THE EVENING AS THE LEADING EDGE OF A DISTANT UPPER LOW DRAWS CLOSER. CONDITIONAL THREAT OF MORE LATE- DAY TSRA ON SATURDAY AS A WEAK FRONT APPROACHES FROM THE PANHANDLE...BUT CONFIDENCE IS TOO LOW FOR PROB30 MENTION. && .PREV DISCUSSION... /ISSUED 314 PM CDT FRI AUG 24 2012/ SHORT TERM... MAIN CONCERN FOR THE SHORT TERM PERIOD IS CHANCES FOR ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS...AS AN UA LOW APPROACHES THE SOUTHERN PLAINS FROM THE WEST. LATEST WATER VAPOR IMAGERY DISPLAYED THE UA LOW PROGRESSING ENE ACROSS SOUTHERN COLORADO/NORTHERN NEW MEXICO. DRIER AIR WAS FILTERING ACROSS THE WRN AND CENTRAL SOUTH PLAINS THIS AFTERNOON...HENCE THE LACK OF SIGNIFICANT CLOUD COVER. HOWEVER...SFC CONVERGENCE WAS NOTED ACROSS THE NWRN SOUTH PLAINS COURTESY OF A SFC TROUGH NORTH OF THE REGION. THUS...AGITATED CU-FIELDS HAVE DEVELOPED AS A RESULT AND THE POTENTIAL FOR STORM DEVELOPMENT EXISTS. FURTHERMORE...SFC-BASED CAPE OF 1.0-1.5 KJ/KG AND PWATS RANGING BETWEEN 1.20-2.00 INCHES ACROSS THE CENTRAL AND EASTERN ZONES MAY RESULT IN ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS LATER THIS AFTERNOON/EVENING. AN INVERTED V-SOUNDING PROFILE...25-35 KTS OF 0-6 KM OF BULK SHEAR AND ADEQUATE PWATS...MAY RESULT IN A FEW STORMS BEING CAPABLE OF PRODUCING BRIEF SEVERE WIND GUSTS...BRIEF MODERATE RAINFALL AND PERHAPS LOW END SEVERE HAIL. TONIGHT INTO EARLY TOMORROW MORNING...THE UA LOW WILL OPEN UP AND ITS TAIL END WILL SWING ACROSS THE CWA DURING THE SAID TIME. BEST LIFT APPEARS TO BE NORTH OF THE SOUTH PLAINS...HOWEVER A PERSISTENT UPSLOPE SFC COMPONENT...LLJ INCREASING TO 35-45 KTS AND DECENT MID LEVEL INSTABILITY STILL EXISTS /600-900 J/KG/...MORE SO ACROSS THE NRN AND NERN ZONES WHICH IS CLOSEST TO THE BEST LARGE SCALE ASCENT. WILL CONTINUE MENTIONABLE POPS TONIGHT...WITH BEST POPS NOTED ACROSS THE AFOREMENTIONED LOCALES. TOMORROW AFTERNOON...MOIST MID LEVELS WILL ENSUE IN ADDITION TO DAYTIME DESTABILIZATION WILL PERHAPS BE ENOUGH TO PROMOTE ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS. FURTHERMORE......A FRONTAL INTRUSION WILL APPROACH THE FAR SWRN TEXAS PANHANDLE...SERVING AS YET ANOTHER FOCUS FOR PRECIP DEVELOPMENT. OVER NIGHT TEMPS WILL GENERALLY BE MILD WITH LOWER 60S NW TO LOWER 70S SE. DAYTIME HIGHS TOMORROW MAY A DEGREE OR TWO WARMER THAN TODAY...WITH UPPER 80S TO LOWER 90S ANTICIPATED. LONG TERM... WE STILL MAY SEE AN OPPORTUNITY OR TWO FOR SHOWERS LATE THIS WEEKEND INTO MONDAY BEFORE CHANCES DWINDLE WITH A BUILDING HIGH PRESSURE RIDGE MUCH OF NEXT WEEK. UNTIL THEN...A COOL UPPER LEVEL TROUGH WILL BE SLOWLY EDGING ACROSS THE AREA SATURDAY NIGHT INTO SUNDAY THOUGH WEAKENING AS MAIN ENERGY MOVES FAR TO THE EAST AND HEIGHTS REBUILD TO THE NORTHWEST. FLOW WILL BECOME MORE NORTHEAST ALOFT AND INCREASINGLY UNFAVORABLE FOR MOVEMENT OF CONVECTION OFF HIGHER TERRAIN TO OUR WEST...BUT MOIST AND UNSTABLE CONDITIONS SHOULD STILL BE ADEQUATE FOR AT LEAST LOW THUNDER CHANCES DURING THIS PERIOD. A SURFACE HIGH PRESSURE RIDGE WILL SETTLE SOUTHWARD AS WELL SUNDAY INTO MONDAY WITH SURFACE TROUGH TO THE SOUTH RESEMBLING A WEAK FRONTAL BOUNDARY JUST SOUTH OF THE AREA...AT LEAST RESULTING IN LOW LEVEL CONVERGENT BOUNDARY SUNDAY INTO EARLY MONDAY. A WEAKNESS ALOFT OVER THE SOUTHERN PART OF THE AREA INTO MONDAY WILL STILL GIVE OPPORTUNITY FOR SHOWERS OR WEAK THUNDERSTORMS TO DEVELOP. SHOWER CHANCES SHOULD DROP FURTHER OR END BY TUESDAY AND BEYOND ALTHOUGH DIFFERENCES REMAIN REGARDING HOW MUCH WEAKNESS ALOFT WILL EXIST. WE INCREASED THUNDER CHANCES SLIGHTLY SATURDAY NIGHT AND ALSO ADDED LOW MENTION ACROSS MAINLY SOUTHWEST ZONES ON MONDAY. FEW OTHER CHANGES OF NOTE THIS TIME WITH TEMPERATURES LIKELY TO REMAIN CLOSE TO NORMAL. RMCQUEEN && .PRELIMINARY POINT TEMPS/POPS...
