AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BROWNSVILLE TX
528 PM CDT WED JUL 26 2006

.UPDATE...UPPER LOW JUST NORTH OF LAREDO IS HELPING CONVECTION TO
FORM AND BACK BUILD ALONG THE CORPUS CHRISTI AND BROWNSVILLE CWA BORDER.
THESE STORMS ARE FORMING OVER NORTHERN JIM HOGG AND MOVING INTO
NORTHWEST BROOKS COUNTIES. HEAVY RAIN IS ASSOCIATED WITH THE
STORMS. OTHER SHOWERS ARE MOVING INTO ZAPATA FROM THE WEST AS WELL
AS STARR COUNTY FROM THE SOUTHWEST. UPDATED THE EVENING FORECAST
TO REFLECT THESE TRENDS WITH THE BEST CHANCES OCCURRING OVER THE
JIM HOGG...BROOKS AND POSSIBLY NORTHERN KENEDY COUNTY. WOULD
EXPECT CONVECTION TO DIMINISH A FEW HOURS AFTER THE SUNSETS. SKIES
WILL REMAIN CLOUDY TO MOSTLY CLOUDY OVERNIGHT AND EARLY THURSDAY
MORNING WITH PARTIAL CLEARING THURSDAY AFTERNOON.

&&

.PREV DISCUSSION...ISSUED 200 PM CDT WED JUL 26 2006...EXCEPT FOR
HIGH CLOUDS BLOWING SOUTH FROM NORTHWEST GULF CONVECTION...LITTLE
OF METEOROLOGICAL SIGNIFICANCE IS TRANSPIRING IN DEEP SOUTH TEXAS.
THERE IS ENOUGH MOISTURE IN PLACE TO KEEP THE THREAT OF ISOLATED
CONVECTION IN THE FORECAST...AND THIS WILL CONTINUE TO BE THE CASE
AS H5 RIDGING AND HIGH PRESSURE DOMINATE THE NORTH
GULF...PROVIDING THE MOISTURE FEED FROM THE SOUTHEAST.

&&

MARINE...BUOY020 CONTINUES TO REPORT WINDS AND SWELLS AT SCA
LEVELS THIS AFTERNOON DUE TO THE STRONGER PGF IN PLACE OVER THE
REGION. THIS WILL LIKELY PERSIST INTO THE OVERNIGHT HOURS AND INTO
THURSDAY MORNING...MAINTAINING THE ROUGH GULF CONDITIONS. THE
GRADIENT WILL SLACKEN ENOUGH ALONG THE BAY TO ALLOW CONDITIONS TO
DROP BELOW SCA LEVELS...SO WILL ALLOW THIS SEGMENT OF THE SCA TO
EXPIRE THIS AFTERNOON. WAVE WATCH III GUIDANCE THEN BEGINS TO
DIMINISH THE WINDS AND SWELLS TOWARDS THIS WEEKEND...AS 500 MB
RIDGING BECOMES MORE ESTABLISHED OVER THE REGION. THIS OVERALL
TREND LOOKS PRETTY GOOD...AND SEE NO REASON TO DEVIATE TOO MUCH
FROM IT.

AVIATION...LOW LEVEL SC/CU CONTINUES TO ADVECT IN OVER DEEP SOUTH
TEXAS FROM NORTHEAST MEXICO...PERIODICALLY DROPPING CEILINGS INTO
THE 2500 TO 3500 FEET RANGE TODAY. THIS WILL LIKELY LINGER INTO THE
AFTERNOON AND EARLY EVENING HOURS...EVENTUALLY WEAKENING LATER
TONIGHT WITH THE LOSS OF THE DAYTIME HEATING. EXPECT OVERALL VFR
CONDITIONS TO PERSIST INTO THE OVERNIGHT HOURS...WITH REDUCED
CEILINGS DUE TO SC/CU RETURNING AFTER 12Z THURSDAY. CURRENT TAF
PACKAGE LOOKS OK.
