AREAS SUBJECT TO FLOODING WHEN WATER BEGINS RISING.

815 PM CST THU APR 03 1997

88D PICTURE MUCH DIFFERENT FM THIS TIME COMPARED TO LAST NIGHT. 00Z
CRP SOUNDING (CALCULATED FM SHARP) SHOWS AMPLE MOISTURE AND
INSTABILITY REMAINING IN PLACE...PW OF 1.86...LI -5 AND CAPE VALUES
OVR 1700 JKG-1. GIVEN THE AFOREMENTIONED PARAMETERS AND THE APPROACH
OF ANOTHER IMPULSE...CONVECTIVE DVLPMNT A GOOD POSSIBILITY...OF WHICH
THE CURRENT FCST AND FFA HANDLES FINE. SURROUNDING 88D SITES ARE
INDICATING SOME CNVTN FIRING ACROSS THE RIO GRANDE SIGNIFYING THE
APPROACH OF THE NXT IMPULSE. ADAP GRAPHICS SHOW WK SFC MOISTURE
CONVERGENCE ACROSS THE S TX...HOWEVER UNLIKE YESTERDAY...STREAMLINE
ANALYSIS DOES NOT SHOW ANY SIGNIFICANT DISCONTINUITY ALONG THE
COASTAL BEND...BUT DOES ALONG THE FNTL BNDRY OVR THE TX PANHANDLE AND
THE BIG BEND REGION. OUTFLO BNDRIES FM CNVTN THIS AM AND FM CNVTN OVR
THE GULF MAY HELP TO FOCUS THE PRECIP ASSOC WITH THE ADVANCING
IMPULSE.

CAP WL LKLY STRENGTHEN IN RESPONSE TO INCREASING WARM H85 WINDS WHICH
WL ALSO AID IN SHIFTING THE MOISTURE POOL TO SE AND E TX. BRO'S CAP
IS ALREADY AROUND 2 DEG C AND GRIDDED ETA DATA NOTES H85 TEMPS
WARMING TO NEAR 20 DEG C TOMORROW ACROSS S TX. IF CAPS CONTINUE TO
STRENGTHEN AND MOISTURE POOLING SHIFTS SIGNIFICANTLY NWD...THE FFA WL
NEED TO BE RE-EVALUATED AND POSSIBLY DROPPED FOR SOME AREAS OF THE
CWA. ANY OF THESE CHANGES CAN BE HANDLE BY FOLLOWING SHIFTS UPON
REVIEW OF THE 00Z OR THE 12Z FRI AM MODEL OUTPUTS.

OTHER THAN IMPULSES CROSSING INTO S TX...FCSTD UVVS ARE NOTED ALONG
AND AHEAD OF THE CF WHICH WL PROGRESS TOWARD S TX FRI. CONVECTIVE
DVLPMNT IS POSSIBLE WITHIN THIS REGIME...PARTICULARLY OVR NRN PRTNS
OF THE FA. MEANWHILE THE PERSISTANT UPR LO WL FINALLY OPEN UP AND
TRACK INTO THE PLAINS ALLOWING FOR DRYING WLY FLOW ALF...SO MAY SEE
