DISCUSSION... CONVECTIVE ACTIVITY LATE THIS AFTERNOON AND THIS EVENING HAS PLAYED OUT VERY CLOSE TO ADVERTISED IN THE AFTERNOON FORECAST PACKAGE. THE INITIAL SURGE OF CONVECTION WHICH DEVELOPED ACROSS CENTRAL TEXAS AND DROPPED INTO THE HILL COUNTRY IS SLOWLY PUSHING WESTWARD ACROSS THE EDWARDS PLATEAU AS IT WEAKENS. ADDITIONAL PROPAGATION ALONG NUMEROUS OUTFLOWS AND ALONG THE N-S ORIENTED SURFACE BOUNDARY DRAPED ACROSS WEST/WEST-CENTRAL TEXAS IS EXPECTED THROUGH THE REST OF THE EVENING AND INTO THE OVERNIGHT HOURS. A COMPLEX OF THUNDERSTORMS HAS ALSO DEVELOPED ACROSS NORTHEASTERN MEXICO JUST WEST OF EAGLE PASS. THIS SYSTEM HAS BEEN SLOWLY TRACKING NORTHWESTWARD...BUT COULD BEGIN TO SHIFT EASTWARD IF IT SYNCHES UP WITH THE TAIL-END OF THE SURFACE BOUNDARY TO ITS NORTH. HAVE TWEAKED POPS/WX/QPF/SKY GRIDS THROUGH THE OVERNIGHT HOURS WITH THE ANTICIPATION OF THE ACTIVITY TO REMAIN CONFINED TO THE EDWARDS PLATEAU/WESTERN HILL COUNTRY/MIDDLE RIO GRANDE PLAINS WITH A GRADUAL TAPERING OFF AFTER MIDNIGHT. POCKETS OF RAIN-COOLED AREAS ARE SHOWING UP ON HOURLY TEMPERATURE OBSERVATIONS...BUT ARE NOT EXPECTED TO SIGNIFICANTLY IMPACT OVERNIGHT LOW TEMPERATURES. PREV DISCUSSION... /ISSUED 645 PM CDT THU AUG 11 2011/ AVIATION... THRU 05Z SCT CLOUDS FROM 6 THSD TO 10 THSD FT WILL CONTINUE WITH HIGHER CLOUDS SCT TO BKN ABOVE 25 THSD FT. SCT SHRA AND TSRA WILL CONTINUE ALONG AND WEST OF A LINE FROM KBMQ TO KHDO TO KEGP THRU 05Z. SCT 05Z SCT TO BKN CLOUDS ABOVE 25 THSD FT WILL CONTINUE. MVFR CIGS WILL DEVELOP FROM VCNTY OF KAUS TO VCNTY OF KSAT AND KSSF AROUND 07Z TO 09Z...AROUND 1 THSD TO 2 THSD BKN. BY 15Z FRIDAY MORNING...SCT CLOUDS AROUND 3 THSD TO 4 THSD FT ARE EXPECTED BECOMING 6 THSD TO 10 THSD SCT AGAIN AFTER 18Z ON FRIDAY. ISOLATED SHRA AND TSRA ARE POSSIBLE ALONG AND WEST OF A KERV TO CARRIZO SPRINGS LINE AFTER 20Z FRIDAY. S TO SE WINDS AT 10 TO 15 KNOTS WILL DIMINISH TO AROUND 10 KNOTS OR LESS AFTER 07Z AND INCREASE TO 10 TO 15 KNOTS AFTER 15Z FRIDAY. PREV DISCUSSION... /ISSUED 318 PM CDT THU AUG 11 2011/ DISCUSSION... CONVECTION PROPAGATING WESTWARD ALONG A FRONTAL BOUNDARY NEAR ABI COULD POSSIBLY ENCOURAGE ORGANIZED THUNDERSTORM DEVELOPMENT TO SPREAD SOUTH INTO THE HILL COUNTRY BY LATE THIS EVENING. AHEAD OF THIS FEATURE...A FEW CONVECTIVE CELLS ARE ALSO FORMING NEAR LLANO WESTWARD TO THE CONCHO RIVER BASIN NEAR SJT. THE ISOLATED ACTIVITY FORMING OVER OUR FORECAST AREA LATE THIS AFTERNOON WILL BE CAPABLE OF PRODUCING STRONG DOWNDRAFTS OF AROUND 50 MPH AND WILL BE MENTIONED IN AN HWO UPDATE...BUT MOST ACTIVITY SHOULD BE BRIEF AND SHORT-LIVED WITH OUT A FOCUSING BOUNDARY. ALOFT...THE RIDGE CENTER IS NEAR WEST CENTRAL TX WHERE THE WEAK FRONTAL BOUNDARY IS TRYING TO PROGRESS SOUTHWARD. THUS WILL KEEP THE FORECAST BASED ON THE 12Z MODEL RUNS WHICH ARE CONSERVATIVE ON POPS AND QPF FOR SOUTH CENTRAL TX. AS SUCH...THE ISOLATED CONVECTION WILL LIMIT THE COOLING POTENTIAL FROM OUTFLOWS...SO THE HEAT ADVY EXTENSION FOR FRIDAY APPEARS TO BE ON TRACK FOR NOW. OVER THE WEEKEND...DRIER MID LEVEL AIR IS EXPECTED TO SEEP SOUTHWARD FROM N CNTRL TX AND ONSHORE FROM THE GULF TO CREATE A DEFORMATION ZONE FOR THE MOISTURE POOLING OVER SOUTH CENTRAL TX. THUS BY SUNDAY...THE RAIN CHANCES DECREASE AND THE LOW LEVEL AIR COULD BECOME SUFFICIENTLY DRY TO REDUCE THE POTENTIAL FOR HEAT ADVY CONDITIONS. THE DIRTY RIDGE ALOFT COULD STILL OFFER A SUPRISE OR TWO THIS WEEKEND AS WEAK MID LEVEL CONVERGENCE FEATURES...SUCH AS THE ONE NOTED THIS MORNING WEST OF DRT...COULD APPEAR ON SHORT NOTICE AND ALTER CONVECTIVE FOCUS ENOUGH TO INFLUENCE TEMPERATURES AND THE GRADUAL FORECAST DEPLETION OF MOISTURE. WILL CONTINUE WITH HIGH TEMPS MOSTLY ABOVE 100 AND MIN TEMPS MOSTLY ABOVE 75 THROUGH THE EXTENDED AS THE UPPER RIDGE APPEARS TO BECOME MORE DOMINANT OVER TX BY THE MIDDLE OF NEXT WEEK. && .PRELIMINARY POINT TEMPS/POPS...
