SOUTH CENTRAL TEXAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX
245 PM CDT WED JUN 11 2003
ISOLD STRONG TSTMS FIRING TO THE WEST THIS AFTN AND BIG QUESTION IS
HOW ORGANIZED THIS CONVECTION WILL BECOME THIS EVENING AS IT MOVS
EWD INTO A VERY UNSTABLE BUT CAPPED AMS. CURRENTLY THE CONVECTION
SEEMS TO BE A RESULT OF STG HEATING BREAKING THE CAP. HOWEVER BOTH
THE MESOETA/ETA AND AVN DEVELOP AN MCS ALONG THE DRY LINE TO THE
WEST THIS EVENING. THE AVN ONCE AGAIN SHOWS MORE DEVELOPMENT TO THE
SOUTH INTO OUR WRN CWA. THIS SCENARIO IS SIMILAR TO WHAT HAPPENED
LAST MON NIGHT AS THE INITIAL MCS OUTFLOW INITIATED A SECONDARY MCS
TO THE SOUTH. WILL LEAN SLIGHTLY TOWARDS THE AVN SOLN AND GO WITH A
HIGHER POPS IN THE WEST/CENTRAL SXNS TONIGHT. APPEARS THERE WILL
INITIALLY BE POTENTIAL FOR SVR IN THE WEST DUE TO HI CAPES AND
INVERTED V SOUNDINGS SUPPORTING DAMAGING WINDS AND LARGE HAIL. IF
AVN SOLN DOES EVOLVE THERE WILL BE A THREAT OF LOCALLY HEAVY RAIN
LATER ALONG SLOW MOVG BOUNDARIES THAT WILL BE PARALLEL TO THE UPR
FLOW. BUT NOT ENUF CONFIDENCE TO MENTION HVY RAIN YET...THEREFORE
MAKE EVENING SHIFT AWARE OF POTENTIAL.
WE STAY IN THE DIRTY SUBTROPICAL FLOW THRU ABOUT SATURDAY WITH THE
CONTD CHANCE OF AFTN HEATING/SHORT WV DRIVEN CONVECTION DRIFTING
INTO THE CWA DURING THE OVERNIGHT HOURS. A GRADUAL SHIFT TO MORE
NWLY/NLY FLOW EVOLVES BY SUNDAY/MONDAY WITH GFS/ECMWF CONTG TO PUSH
A VERY LATE SEASON COLD FRONT INTO S TX SUN NIGHT OR MONDAY MORNING.
THIS WILL NO DOUBT RESULT IN ANOTHER GOOD SHOT AT PCPN WITH THE
FNT. DECREASING CHCS OF RAIN...BUT BELOW NORMAL TEMPS FOR TUE/WED
AS A CLOSED LOW DROPS INTO NE TX WITH ANY PCPN MOST LIKELY OFF TO
THE EAST. 01/03
