AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX 638 AM CDT SUN JUL 8 2007 .AVIATION... MIXED-BAG OF PREVAILING MVFR AND IFR CIGS/VSBYS TO GO VFR BETWEEN 15-17Z THIS MORNING. A BATCH OF SHOWERS AND THUNDERSTORMS NORTH AND WEST OF KSAT WILL CONTINUE MOVING ENE WITH TIME...WITH SCATTERED THUNDERSTORMS POPPING-UP LATER DUE TO DAYTIME HEATING. MVFR CIGS WILL RETURN TONIGHT BETWEEN 06-09Z. A MODERATE SOUTHERLY LOW LEVEL FLOW WILL CONTINUE. && .PREV DISCUSSION... /ISSUED 443 AM CDT SUN JUL 8 2007/ DISCUSSION... A CLUSTER OF SHOWERS AND THUNDERSTORMS ARE MOVING ACROSS THE HILL COUNTRY THIS MORNING AND COULD PRODUCE SOME SPOTTY FLOODING CONCERNS, BUT THEIR SHAPE AND MOVEMENT IS NOT AS CONDUCIVE TO TRAINING AS THE NOCTURNAL ACTIVITY SEEN THE PAST COUPLE NIGHTS. THUS WILL HOLD OFF A FFA UNLESS TRENDS TAKE A TURN FOR THE WORSE. LOW LEVEL DEWPOINTS IN THE LOW TO MID 70S HINT AT DEEP TROPICAL MOISTURE THIS MORNING, BUT THE INCREASED ZONAL WIND PATTERN DEVELOPING MAINLY AT 500 HPA AND ABOVE SHOULD HELP SUPPORT INCREASED CELL SPEED AND PERHAPS SOME INCREASED SUBSIDENCE TO LIMIT COVERAGE. ASSUMING MAINLY SCATTERED CONVECTION TODAY, MAX TEMPS SHOULD APPROACH THE WARMER GFS BASED TEMPERATURE GUIDANCE, BUT THE COOLER NAM GUIDANCE WAS BLENDED IN FOR THE NEXT TWO DAYS. MODEL TRENDS CONTINUE TO FAVOR ONLY ISOLATED TO SCATTERED DIURNAL SHOWERS AND THUNDERSTORMS DURING THE DAYTIME HOURS MON-WED, MAINLY EAST OF I-35 WITH A GRADUAL DECREASING TREND AS DRIER AIR BLENDS IN FROM ALOFT AND FROM THE WEST. BY LATE WED INTO THU, THE MID LEVEL WINDS FORECAST INDICATES MID-LEVEL STABILITY AND POSSIBLY A DRY DAY ACROSS ALL AREAS. THE DRY SPELL MAY BE SHORT-LIVED FOR EASTERN AND NORTHERN COUNTIES AS A NW FLOW PATTERN SETS UP OVER THE RED RIVER VALLEY FOR NEXT WEEKEND. IN GENERAL, HAVE LEANED 10 PERCENT HIGHER THAN MEDIUM RANGE GUIDANCES ON POPS FOR MUCH OF THE WORK WEEK, SINCE THE WEAK SHEAR PATTERN COULD STILL COMBINE WITH MESOSCALE CONVECTIVE INFLUENCES TO ALTER THE PATTERN FOR INCREASING STABILITY ALOFT. && .PRELIMINARY POINT TEMPS/POPS...
