AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX 1200 PM CDT WED JUN 23 2004 .UPDATE... TROUGH/SHEAR AXIS CENTERED OVER GONZALES AND DEWITT COUNTIES AT LATE MORNING WITH TWO BANDS OF CONVECTION NOTED FEEDING INTO IT. ALSO, TROUGH APPROACHING THE RIO GRANDE CONTINUES TO GENERATE CONVECTION MAINLY OVER THE SOUTHWEST. AIRMASS IN BETWEEN SYSTEMS HAS STABILIZED AND DRIED SOMEWHAT. AS A RESULT, HAVE DROPPED FLASH FLOOD WATCH FROM AREAS ALONG AND WEST OF I-35 FROM FFA AND LOWERED POPS MOST AREAS, ALTHOUGH HAVE EXTENDED WATCH UNTIL 7 PM. DUE LESS CLOUDS AND RAIN HAVE INCREASED AFTERNOON TEMPERATURES ESPECIALLY CENTRAL AND NORTH. WILL LIKELY LOWER SOME POPS FURTHER IN THE SHORT-TERM IN LATER FORECASTS. OTHERWISE, ONGOING FORECASTS GENERALLY ON TRACK. && .PREV DISCUSSION... TROF AXIS FROM 700 TO 300 MB REMAINS WEST OF SOUTH CENTRAL TEXAS TODAY. LOW AMPLITUDE AND QUICK MOVING TROF MOVING NE ACROSS AREA TODAY APPEARS TO LINK WITH MOISTURE STREAM FROM THE SOUTH. THIS PATTERN SUPPORTS CONTINUED HIGH CHANCE OF RAIN FROM SHOWERS AND THUNDERSTORMS. WILL SHOW FLOOD WATCH FOR FLASH FLOODING FOR SOUTH CENTRAL TEXAS TODAY THRU 600 PM CDT. BEST CHANCE OF RAIN FOR TONIGHT SHOWS UP IN THE EVENING PERIOD...THEN CHANCE OF RAIN DIMINISHES LATE TONIGHT. UPDATED FORECASTS TO SHOW LESS THAN OF RAIN FOR LATE TONIGHT...DIMINISH TO A SLIGHT CHANCE OF SHOWERS. BY THURSDAY COMPOSITE OF FORECAST SOLUTIONS SHOW WEAK TROF AXIS ALOFT A LITTLE FURTHER EAST...OVER THE EAST PART OF SOUTH CENTRAL TEXAS. LIFT FOR RAIN THURSDAY MAY DEPEND MORE ON DAYTIME HEATING. EVEN THROUGH THIS IS THE CASE...HIGH SOIL MOISTURE AND DAYTIME HEATING ARE EXPECTED TO SUPPORT CHANCE FOR RAIN THURSDAY...WITH POPS A LITTLE LESS THAN TODAY. ON FRIDAY STRONG WESTERLIES TO THE NORTH ATTEMPT TO MOVE WEAK TROF AXIS SLOWLY EAST OF THE AREA. STILL THOUGH LITTLE CAPPING IS SHOWN BY THIS LATE JUNE 2004 PATTERN...AND ONCE AGAIN DAYTIME HEATING COULD VERY WELL SET OFF SCATTERED SHOWERS AND THUNDERSTORMS...SO CONTINUED CHANCE OF SHOWERS OR THUNDERSTORMS FOR FRIDAY. ON SATURDAY AND SUNDAY FORECASTS SHOW ANOTHER LOW AMPLITUDE TROF COMING FROM THE WEST...KEEPING CHANCE OF RAIN FOR AREA SATURDAY AND SUNDAY. ACTIVE SOUTHERN STREAM WESTERLIES HAVE HELPED TO MAKE JUNE 2004 WET FOR SOUTH CENTRAL TEXAS. THESE SOUTHERN STREAM WESTERLIES APPEAR TO BE AFFECTED BY TELECONNECTION PATTERNS FROM THE PACIFIC OCEAN...A TREND THAT BEGAN IN LATE DEC 2003 AND JAN 2004. AT ANY RATE BY THE EARLY PART OF NEXT WEEK...LATEST GFS RUN AND COMPOSITE FORECASTS CONTINUE TO SHOW WEAK TROF AXIS ALOFT OVER SOUTH CENTRAL TEXAS...THAT SLOWLY WEAKENS NEXT WEEK...AS ACTIVE SOUTHERN STREAM WESTERLIES AND NORTHERN STREAM WESTERLIES DRIFT SLOWLY NORTHWARD. SOME TYPE OF RIDGE ALOFT TRIES TO BUILD OVER THE AREA FROM THE SOUTH...VERY GRADUALLY DAY BY DAY NEXT WEEK INTO THE EARLY PART OF JULY. THE PROCESS OCCURS IN COMPOSITE FORECASTS SLOWLY SUCH THAT BY LATE NEXT WEEK TO THE EARLY PART OF THE FOLLOWING WEEK...IF THESE SOLUTIONS MAKE THE MARK...CHANCE OF RAIN COULD FALL TO LESS THAN 10 TO 20 PERCENT. THIS SOLUTION THOUGH IS FRAGILE CONSIDERING PAST TRENDS AND COMPLEXITY ON HOW FAST WESTERLIES COULD RETREAT NORTHWARD. IN THE MEANTIME CHANCE OF RAIN CONTINUES NEXT FEW DAYS...KEEPING JUNE 2004 WET. && .EWX WATCHES/WARNINGS/ADVISORIES... FLASH FLOOD WATCH ALONG AND EAST OF LEXINGTON TO SEGUIN TO JOURDANTON LINE THROUGH 24/00Z. && 04/06
