NATIONAL WEATHER SERVICE CORPUS CHRISTI TX
230 AM CDT WED OCT 8 1997

ALL THREE MODELS SHOW DIFFERENT SOLUTIONS IN THE HANDLING OF THE LOW
PRES FEATURES IN THE WRN GULF AND TX VALLEY REGION NXT 48HRS.  THE
ETA AND AVN ARE THE WETTEST WITH A SFC TROF DVLPG ALG THE TX COAST
AND A NEARLY STATIONARY DISTURBANCE ALOFT.  NGM IS MUCH FURTHER S...
ABT 12HRS SLOW AND IS ALSO THE DRIEST.  A BLEND OF THE HIGHER
RESOLUTION ETA MODEL AND AVN ARE FAVORED IN THIS FCST CYCLE.

WITH THE DEVELOPMENT OF THE AFORMENTIONED SYSTEM TNGT A MORE ELY
FETCH OF MOISTURE WILL FLOW INTO THE COASTAL BEND ON THURS.  SFC
WINDS WILL BACK TO THE NE TNGT OVER THE INLAND COUNTIES WITH SE WINDS
ALG THE IMMEDIATE COAST.  THIS FLOW WILL CREATE DESCENT SFC MOIST
CONV ALG THE MID COASTAL PLAINS THURS PROVIDING A FOCUS FOR PRECIP.
AS THE H85 FLOW BECMS MORE ELY THE MOISTURE PLUME PROPAGATING UP THE
WRN GULF WILL BE REDIRECTED TOWARD THE MID COAST.  THIS WILL PLACE
THE COASTAL BEND REGION IN A POSITION FOR TRAINING PRECIP.  MID-UPPER
LVL MOISTURE FROM "PAULINE" WILL ALSO ADD TO THE MIX.

DEEP TPCL MOISTURE IS IN PLACE WITH THE GULF WIDE OPEN.  PWS ARE
PROGGED >2.20 INCHES THRU 48HRS.  MODEL TIME SECTIONS SHOW POS UVM
THRU THE ENTIRE FCST CYCLE WITH MEAN RH'S >70%.  ETA QPF AND 98Q
PAINT 2.00 INCH AVG RAINFALL AMTS OVER MOST OF THE TX COAST ON THURS.
WILL GO ALG WITH THIS SCENARIO WITH A GOOD CHC OF RAIN THURS
CONTINUING INTO FRI.  WILL MENTION LCLY HVY RAIN FOR THE ERN COUNTIES
FROM CRP-VCT FOR THURS.  FFG IS QUITE LOW IN THE RKP-VCT AREA WHERE
3HR TOTALS OF <2.00 WILL CAUSE FLASH FLOODING...3.00 INCHES IN CRP.
THE MID SHIFT WILL NEED TO THINK ABT A FFA FOR ERN 1/3RD OF THE CWA
FOR THURS.

WITH THIS IN MIND...VCT WILL HAVE A GOOD CHC AT BREAKING THEIR ALL
TIME YEARLY RAINFALL RECORD THIS WEEK.  VCT'S CURRENT YRLY TOTAL
