AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX 1224 AM CDT THU JUN 28 2007 .AVIATION... UNSTABLE AIR CONTINUES TO FOCUS ISOLATED TO WIDDELY SCATTERED THUNDERSTORM DEVELOPMENT OVER PARTS OF SOUTH CENTRAL TEXAS. THE AREA OF MOST UNSTABLE AIR WILL BE ALONG THE I-35 CORRIDOR THROUGH 07Z AND OVER THE HILL COUNTRY AS ANOTHER AREA OF THUNDERSTORMS MOVES SOUTH FROM WEST CENTRAL TEXAS AFTER 07Z. THUNDERSTORM FOCUS THROUGH 9Z LOOKS TO BE HIGHEST OVER NORTH CENTRAL TEXAS NEAR THE ACT AREA. EVENING OBSERVATIONS SUGGEST A REDUCED THREAT FOR CONTINUOUS THUNDERSTORM REDEVELOPMENT, SO WILL KEEP CONVECTIVE ELEMENTS OUT OF THE PREVAILING GROUPS. SOME MVFR CIGS ARE TO BE EXPECTED IN THE OVERNIGHT HOURS, BUT WILL BE INTERRUPTED BY THUNDERSTORM OUTFLOWS AT TIMES. WITH THE LACK OF SIGNIFICANT ORGANIZATION IN THESE STORMS, WILL ADOPT THE 00Z NAM LINE OF THINKING THAT ADDITIONAL THUNDERSTORM DEVELOPMENT WILL OCCUR ALONG THE I-35 CORRIDOR AFTER DAYBREAK. && .PREV DISCUSSION... /ISSUED 814 PM CDT WED JUN 27 2007/ UPDATE... MADE A QUICK UPDATE TO SHIFT HIGHER POPS EASTWARD FOR THE EVENING WHERE LINE OF CONVECTION HAS BECOME MORE ORGANIZED AND TRAINING JUST AHEAD OF THE UPPER TROF AXIS. STORMS ARE MUCH LESS ORGANIZED AND SPOTTY ON THE BACK SIDE OF THE TROF AXIS OVER THE CENTRAL AND WESTERN CWA. SCATTERED DEVELOPING STORMS TO THE NORTH IN THE ABILENE AREA POSSIBLY THE BEGINNINGS OF THE NEXT ROUND OF ORGANIZED CONVECTION/MCS THAT COULD AFFECT OUR CWA AFTER MIDNIGHT AND INTO THE EARLY MORNING HOURS WHEN THE NOCTURNAL LOW LEVEL JET WILL FEED INTO THIS CONVECTION...SO HAVE LEFT HIGH POPS AND QPF AMOUNTS AS IS. PREV DISCUSSION... /ISSUED 642 PM CDT WED JUN 27 2007/ AVIATION... FOCUS FOR THUNDERSTORMS APPEARS TO BE CONVERGING ON THE I-35 CORRIDOR TERMINALS EARLY THIS EVENING. A FEW AREAS NEAR THESE STORMS COULD SEE BRIEF MVFR CIGS AND VSBYS WITH WIND GUSTS TO 30 KTS POSSIBLE. LATER TONIGHT, THE HEAVY RAINS AND LOW CIGS SHOULD BECOME MORE WIDESPREAD ALONG THE I-35 CORRIDOR WITH A POSSIBLE WARM CORE AREA OF RAIN DEVELOPING OVER THE EASTERN HILL COUNTRY AFTER 01Z. IMPROVED CIG AND VSBY CONDTIONS ARE EXPECTED AFTER DAYBREAK, BUT THE CHANCE FOR CONVECTION WILL CONTINUE THROUGH THE DAYTIME. MEANWHILE LITTLE ACTIVITY IS EXPECTED TO AFFECT THE DRT AREA, WITH PERHAPS A BRIEF SHOT OF THUNDERSTORMS AROUND MIDNIGHT, AND BRIEF MVFR CIGS POSSIBLE AROUND DAYBREAK. PREV DISCUSSION... /ISSUED 308 PM CDT WED JUN 27 2007/ DISCUSSION... THIS AFTERNOON THE CENTER OF THE BROAD UPPER LEVEL LOW PRESSURE SYSTEM WAS CENTERED OVER SOUTHWEST OKLAHOMA. A SMALLER SCALE CIRCULATION...POSSIBLY A MCV...WAS LOCATED BETWEEN SAN ANGELO AND BROWNWOOD. CONVECTION ASSOCIATED WITH THIS SMALL SCALE FEATURE WAS LOCATED NORTH OF LLANO AND BURNET COUNTIES. MODEL SOLUTIONS ARE IN GENERAL AGREEMENT THAT ANOTHER CONVECTIVE COMPLEX ASSOCIATED WITH A VORT LOBE OR MVC WILL DEVELOP ACROSS WEST CENTRAL TEXAS AND MOVE SOUTHWARD ACROSS OUR CWFA TONIGHT AND THURSDAY. ONCE AGAIN WITH THE TROPICAL AIRMASS IN PLACE...LOCALLY HEAVY RAINFALL IS LIKELY WHICH WILL CAUSE FLASH FLOODING. THE GFS DOES PRODUCE A QPF BOMB OVER THE HILL COUNTRY AND SOUTH CENTRAL TEXAS TONIGHT AND THURSDAY. THE NAM ALSO GENERATES A QPF BOMB...BUT ITS LOCATION IS OVER OUR NORTHEAST COUNTIES AND JUST NORTH OF THE EASTERN HILL COUNTRY. WHAT IS LIKELY IS ANOTHER HEAVY RAIN EVENT WILL OCCUR SOMEWHERE OVER OUR CWFA TONIGHT INTO THURSDAY...THUS THE FLASH FLOOD WATCH HAS BEEN EXTENDED UNTIL NOON THURSDAY. THE WET WEATHER PATTERN WILL CONTINUE THRU AT LEAST THE MIDDLE OF NEXT WEEK. THE WEAKNESS IN THE RIDGE/SHEAR AXIS WILL PERSIST ACROSS TEXAS WITH THE TROPICAL AIRMASS ENTRENCHED ACROSS SOUTH TEXAS. THUS SHOWERS AND THUNDERSTORMS WILL CONTINUE IN THE FORECAST THRU NEXT WEEK. ADDITIONAL HEAVY RAIN EVENTS WILL STILL BE POSSIBLE ACROSS OUR CWFA...DEPENDENT UPON THE LOCATION OF MESOSCALE BOUNDARIES AT THE SFC AND WEAK MID LEVEL CIRCULATIONS ALOFT.
