AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX 923 PM CDT FRI OCT 22 2004 .UPDATE...MAIN AREA OF RAIN ASSOCIATED WITH A PRE FRONTAL TROUGH NOW INTO THE HILL COUNTRY. TO THIS POINT...JUST A FEW STORMS HAVE BEEN SEVERE AND RAPID STORM MOVEMENT HAS AVERTED FLOODING PROBLEMS. SHOWERS AND THUNDERSTORMS TRIGGERED BY THE LOW LEVEL JET ARE STREAMING NORTH JUST WEST OF THE I-35 CORRIDOR. WE EXPECT CELL MERGERS WITH THE MAIN RAIN AREA AND HEAVY RAINS MAINLY OVER LLANO...BURNET...WILLIAMSON...BLANCO AND TRAVIS COUNTIES WITHIN THE NEXT HOUR OR TWO. WILL MAKE ONLY MINOR CHANGES TO GRIDS TO REFLECT NEAR TERM TEMP AND DEW POINT TRENDS. ZONE FORECAST LOOKS GOOD AND NO UPDATE ISSUED TO THAT. && .PREV DISCUSSION... SEVERE WEATHER AND FLASH FLOODING POTENTIAL APPEARS TO HAVE INCREASED WITH SATELLITE VIS AND SURFACE ANALYSIS INDICATING COOL OUTFLOW ESTABLISHING A SURFACE BOUNDARY ALONG THE NORTHERN BORDER OF OUR FORECAST AREA. THIS FEATURE HAS TRIGGERED A CONVECTIVE BAND OVER THE EASTERN HILL COUNTRY WHICH COULD SET A STAGE FOR TRAINING THUNDERSTORMS LATE THIS AFTERNOON INTO THIS EVENING. WITH THE INFLUX OF SUNSHINE OVER OUR AREA SOUTH OF THE THICKER CLOUDS TO THE NORTH, EXPECT THE CONTRAST TO ESTABLISH A FRONTAL BOUNDARY FAIRLY EARLY THIS EVENING AND ALMOST WIDESPREAD CONVECTION FORMING ALONG AND NORTH OF A BRACKETTVILLE TO BURNET LINE TO HELP ESTABLISH THIS BATTLEGROUND BY AROUND 00Z. SATELLITE IMAGERY INDICATES THAT THIS AREA IS ALREADY UNSTABLE WITH GOOD VERTICAL DEVELOPMENT OF CUMULUS AS OF 3 PM. LATER TONIGHT,ADDITIONAL CONVECTION ALONG A PACIFIC FRONT SHOULD SUPPORT TRAINING OF CELLS AS THE FRONT BEGINS TO STALL OVER THE FORECAST AREA. CURRENTLY EXPECT THE STALL TO OCCUR NEAR THE ESCARPMENT BY MIDDAY SATURDAY, WITH 06Z WS-ETA SHOWING GOOD AGREEMENT WITH 12Z GFS ON HIGHEST PRECIP ALONG AND NORTH OF THE ESCARPMENT BETWEEN 6Z AND 12Z SATURDAY. FRONT IS EXPECTED TO WASH OUT BUT THE MOISTURE IS PROGGED TO KEEP COMING WITH THE UNSTABLE SW FLOW ALOFT REMAINING TAPPED INTO THE PACIFIC TROPICS. SUNDAY STILL APPEARS LIKE A WET FORECAST BUT WILL NOT GO AS AGGRESSIVE ON POPS AS THE GFS FOR NOW SINCE THE QPF DEPENDS LARGELY ON WHAT HAPPENS TO THE WEAK TROPICAL DISTURBANCE SOUTH OF THE BAJA PENINSULA. WILL CALL FOR A MOIST AND WARM PATTERN FOR THE REST OF THE 7 DAY FORECAST PERIOD. HOWEVER, WILL KEEP POPS ON THE LOW SIDE DUE TO THE CONTINUED PRESENCE OF THE UPPER RIDGE OVER THE GULF COAST. WILL BRING BACK SLIGHT INCREASE IN POPS IN THE LAST DAY OR TWO SINCE AN UPPER TROUGH OVER THE DESERT SW LOOKS READY TO MAKE A MOVE EAST BY THEN. && .EWX WATCHES/WARNINGS/ADVISORIES... NONE. && 03/13
