820 PM CDT TUE JUL 24 2007

.UPDATE...CRP RADAR CONTINUES TO INDICATE MOST EFFICIENT RAIN
PRODUCING THUNDERSTORMS REMAINING CONFINED TO THE WEST OF HIGHWAY
281. THIS TREND IS EXPECTED TO CONTINUE OVERNIGHT AS SATELLITE
DEPICTS SHORT WAVE OVER SOUTH CENTRAL TEXAS THAT IS POISED TO MOVE
OVER RIO GRANDE AND RIO GRANDE PLAINS. THIS SHORT WAVE IN CONCERT
WITH AMPLE LOW LEVEL MOISTURE...BEST INSTABILITY AND MOISTURE
CONVERGENCE OVER THE WESTERN PART OF THE CWA WILL STILL KEEP
POTENTIAL OF FLASH FLOODING OVER THE RIO GRANDE PLAINS. SATELLITE
AND RADAR TRENDS ALREADY STARTING TO SHOW STORMS BEGINNING TO FILL
IN ALONG THE INSTABILITY AXIS NEAR THE RIO GRANDE. HENCE...WILL
RETAIN THE FLASH FLOOD WATCH FOR DUVAL...LASALLE...MCMULLEN AND
WEBB COUNTIES THROUGH 7 AM.

&&

.AVIATION...SCT-NUM RWS/TSTMS WILL CONTINUE UNTIL 03Z FM COT-ALI-LRD
THEN GRADUALLY DISSIPATE WITH LOSS OF HEATING. IFR CONDS AND GUSTY
WINDS UP TO 35 KTS POSSB IN AND NEAR THESE TSTMS. VFR CONDS WILL
THEN GNRLY PREVAIL OVERNIGHT. SCT-NUM RWS/TSRA WILL RE-DVLP ACROSS
THE COASTAL BEND FROM CRP-VCT-ALI WED MORNING AND SPREAD WEST DURG
THE AFTN HOURS. ONCE AGAIN...MVFR/IFR CONDS WILL OCCUR IN THESE
TROPICAL DOWNPOURS AS WELL AS WIND GUSTS UP TO 35 KTS.

.PREV DISCUSSION... /ISSUED 216 PM CDT TUE JUL 24 2007/

SHORT TERM (TONIGHT THROUGH WEDNESDAY NIGHT)...UPPER LOW CONTINUES
TO TAKE SHAPE OVER SOUTH CENTRAL TEXAS ATTM AND WILL REMAIN FIXED
OVER THE REGION THROUGH THE SHORT TERM. SERIES OF S/WS WILL PIVOT
AROUND THE TROUGH BRINGING SCT-NUM SHOWERS AND THUNDERSTORMS TO THE
REGION. THE BEST CHANCE OF RAIN WILL BE OVER THE RIO GRANDE
PLAINS OVERNIGHT WHERE NEXT S/W CURRENTLY MOVING ACROSS THE HILL
COUNTRY IS TAKING AIM. NAM/GFS MODELS INDICATE GOOD UPR DIFLUENCE
OUT WEST TONIGHT AND PLENTY OF MOISTURE. MEAN WIND VECTORS
INDICATE VERY SLOW STORM MOTIONS TONIGHT THUS WILL POST A FFA FOR
THE WEST TONIGHT. MOISTURE ADVECTION WILL INCREASE OVER THE
COASTAL BEND LATE TONIGHT AND DURING THE DAY WED. DAYTIME HEATING
COMBINED WITH MOD UPR DIFLUENCE...STATIONARY MID LVL LOW AND A
SFC BOUNDARY WILL ALL COMBINE TO PRODUCE SHOWERS AND THUNDERSTORMS
WITH LOCALLY HEAVY RAIN ON WED. MAX TEMPS WERE LOWERED FOR WED TO
ACCOUNT FOR THE ABUNDANCE OF CLOUDS AND RAIN. MAY VERY WELL NEED
TO ISSUE A FFA FOR THE COASTAL BEND ON WED...BUT WILL LET THE MID
SHIFT GET ONE FINAL LOOK.

MARINE...THE ONSHORE FLOW WILL GRADUALLY INCREASE THROUGH THURSDAY
WITH SEAS BUILDING TO 3-5 FEET OVER THE OFFSHORE WATERS DUE TO
INCREASING PGF AND THE APCH OF THE NEXT TROPICAL WAVE. SCT SHOWERS
AND THUNDERSTORMS WILL BECOME MORE NUMEROUS WED NGT AND THU AS THE
TROPICAL WAVE APPROACHES.

AVIATION...VFR CONDITIONS ARE EXPECTED TO PREVAIL THROUGH THE
EVENING HOURS EXCEPT IN THUNDERSTORMS WHERE IFR CONDITIONS ARE
POSSIBLE. WIDELY SCT SH/TSRA ARE EXPECTED FROM ALI-CRP-VCT AND
SCT-NUMEROUS SH/TSRA ARE EXPECTED FROM LRD-COT. MVFR CEILINGS WILL
DEVELOP ACROSS THE REGION FROM 06Z-14Z. SCT-NUMEROUS SH/TSRA WILL
DEVELOP ACROSS THE COASTAL BEND FROM CRP-VCT WEDNESDAY MORNING WITH
IFR CONDITIONS POSSIBLE IN HEAVY RAIN.

LONG TERM...(THURSDAY THROUGH TUESDAY)...THE MOST RECENT GFS
DETERMINISTIC/NAM SOLNS PROG THE UPPER LOW TO PROVIDE SYNOPTIC
SCALCE ASCENT OVER THE REGION AT LEAST THROUGH SUN...BEFORE
RETROGRADING SIGNIFICANTLY WEST OF THE AREA. THE GFS MAINTAINS
COPIOUS MSTR. GFS SOUNDINGS SUGGEST LIMITED STORM MOTION DRG THE
PERIOD. FURTHER...THE GFS PROGS THE TROPICAL WAVE...EXTENDING FROM
THE BAY OF CAMPECHE TO SOUTH TX...TO REMAIN QUASI-STATIONARY. THE
COMBINATION OF UPPER/SFC FORCING...MSTR/INSTABILITY...EXPECT
CONVECTIVE ACITIVITY...ESP THROUGH SUN. COPIOUS MSTR/LIMITED
VERTICAL SHEAR/THERMODYNAMIC PROFILE/QUASI-STATIONARY BNDRY MAY
CONTRIBUTE TO A HEAVY RAINFALL/FLASH FLOOD EVENT THU-SAT. DRG THE
MON-TUE PERIOD...BOTH THE GFS AND NOGAPS DEVELOP AN UPPER RIDGE OVR
THE REGION RESULTING IN/SUGGESTIVE OF INCREASING SUBSIDENCE. THE GFS
LOWERS PW VALUES DRG MON-TUE. CONCUR WITH THE WAVEWATCH SOLN THAT
SEA HGTS WL REMAIN BELOW SCA THRESHOLD.

602 AM CDT TUE JUL 24 2007

THIS HAZARDOUS WEATHER OUTLOOK IS FOR SOUTH TEXAS AND THE MIDDLE
TEXAS COASTAL WATERS.

.DAY ONE...TODAY AND TONIGHT

SCATTERED SHOWERS AND THUNDERSTORMS WILL OCCUR MAINLY OVER THE
RIO GRANDE PLAINS AND BRUSH COUNTRY TODAY AND TONIGHT AS AN UPPER
LEVEL DISTURBANCE APPROACHES FROM THE NORTH. THE THUNDERSTORMS
WILL BE CAPABLE OF PRODUCING LOCALLY HEAVY RAINFALL LEADING TO
FLASH FLOODING. RAIN AMOUNTS OF 2 TO 5 INCHES WILL BE POSSIBLE
WITH THE STRONGER THUNDERSTORMS.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY

AN UPPER-LEVEL LOW PRESSURE SYSTEM IS FORECAST TO MEANDER ACROSS
CENTRAL TEXAS THROUGH FRIDAY BEFORE FINALLY DRIFTING WEST INTO
MEXICO OVER THE WEEKEND.  THE LOW WILL INTERACT WITH A WEAK TROPICAL
WAVE TO PRODUCE SCATTERED...AND AT TIMES NUMEROUS SHOWERS AND
THUNDERSTORMS ACROSS SOUTH TEXAS.  THIS UPPER-LEVEL LOW IS SIMILAR
TO SEVERAL SYSTEMS THAT HAVE ALREADY CAUSED HEAVY RAINFALL AND
FLOODING ACROSS MUCH OF TEXAS IN THE PAST SEVERAL MONTHS AND
ADDITIONAL LOCALLY HEAVY RAINFALL IS EXPECTED WITH THIS SYSTEM.  THE
BEST CHANCE FOR STORMS AND HEAVY RAINFALL WILL BE WEDNESDAY THROUGH
SATURDAY...BUT SCATTERED THUNDERSTORMS WILL REMAIN IN THE FORECAST
THROUGH THE WEEKEND.  SHOWERS AND THUNDERSTORMS WILL BE CAPABLE OF
PRODUCING LOCALLY HEAVY RAINFALL WITH SCATTERED 1 TO 2 INCH AND
LOCALIZED 3 TO 5 INCH RAINFALL TOTALS EACH DAY MAINLY BETWEEN
WEDNESDAY AND FRIDAY.  THESE RAINFALL TOTALS WILL ADD UP THROUGH THE
END OF THE WEEK LEADING TO AN INCREASING THREAT FOR FLASH FLOODING.
SEVERAL RIVERS IN THE AREA REMAIN NEAR OR ABOVE FLOOD STAGE DUE TO
RECORD RAINFALL AMOUNTS FOR THE MONTH OF JULY AND ADDITIONAL HEAVY
RAINFALL WILL ONLY EXACERBATE THE RIVER FLOOD SITUATION.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION IS NOT ANTICIPATED.
