SOUTH CENTRAL TEXAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX
905 PM CDT FRI MAY 4 2001
LINE OF CONVECTION PICKING UP FORWARD SPEED...AND WELL BEHAVED.
WILL MAKE ONLY MINOR CHANGES TO ONGOING FORECAST, AND REMOVE FLASH
FLOOD WATCH FOR WESTERN MOST COUNTIES.
.EWX...FLASH FLOOD WATCH THROUGH TONIGHT EASTERN HILL COUNTRY AND
PORTIONS OF SOUTH CENTRAL.
06/02/18/DC
PREVIOUS DISCUSSION.............
WILL EXTEND THE FLASH FLOOD WATCH EAST INTO CENTRAL AND NORTHEASTERN
SECTIONS OF SOUTH CENTRAL TEXAS THIS AFTERNOON AS MOST MODELS DRAG A
SLOW MOVING COMPLEX OF THUNDERSTORMS THROUGH THE AREA TONIGHT. ETA
MODELS WHILE SHOWING POOR PERFORMANCE ON PRECIP FORECASTING HAVE
DONE WELL ON PRECIPITABLE WATER VALUES. STRONG SHORTWAVE LIFTING OUT
OF MEXICO IS TRIGGERING CURRENT THUNDERSTORM ACTIVITY, AND NORTHEAST
MOVEMENT OF THE SHORTWAVE COMBINED WITH GOOD DIFFULENCE ALOFT WILL
ALLOW FOR HEAVY RAINS TO MOVE OVER THE PROPOSED WATCH AREA.
SOUTHEAST COUNTIES MAY MISS OUT ON THE HEAVIEST PART OF THE SQUALL
SO WILL ONLY MENTION LOCALLY HEAVY RAINFALL HERE. LATE TOMORROW THE
AREA WILL LIKELY SEE ANOTHER GOOD FLARE UP OF ORGANIZED
THUNDERSTORMS AND A CHANCE FOR FLOODING, BUT WILL NOT EXTEND THE
WATCH WITH UNCERTAINTY IN WHICH AREAS WILL RECEIVE HEAVIEST RAINS
FOR TONIGHT. GUIDANCE TEMPERATURES LOOK APPROPRIATELY MILD FOR THE
NEXT FEW DAYS.
MODELS GOING IN DIFFERENT DIRECTIONS BEYOND TUESDAY WITH 12Z AVN
ACCELERATING THE UPPER LOW POSITION TO SUPPORT DRY WEATHER OVER
SOUTH TX WEDNESDAY. GUIDANCE NUMBERS CLOSE TO CLIMO, BUT CLIMO EVEN
CALLS FOR A CHANCE OF RAIN. MRF SUGGESTS NW FLOW PATTERN LATE IN THE
WEEK AND WHILE NOGAPS SUGGESTS PROLONGED INSTABILITY IN THE BAJA
REGION. THUS CAN NOT RULE OUT AT LEAST SLIGHT CHANCE POPS FOR ANY
DAY THROUGH NEXT FRIDAY.
