AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BROWNSVILLE TX
232 PM CDT FRI JUN 27 2014

.SHORT TERM /NOW THROUGH SATURDAY NIGHT/...A GOOD SPLATTERING OF
CUMULUS AND ALTOCUMULUS ACROSS DEEP SOUTH TEXAS THIS AFTERNOON
WITH POP-UP SHOWERS CONFINED TO MOSTLY EAST OF JIM HOGG AND STARR
COUNTIES WITH A FEW THUNDERSTORMS ROLLING UP THE COAST. FORECAST
IS ON TRACK WITH NO CHANGES AT THIS TIME...TEMPERATURES MOSTLY IN
THE LOWER 90S...PARTLY TO MOSTLY CLOUDY SKIES...AND 30 POPS EAST
OF HBV-RGC LOOK REASONABLE.

MID LEVEL WEAKNESS ACROSS THE AREA OVER THE PAST FEW DAYS THAT HAS
BROUGHT THE INCREASE IN PRECIPITATION WILL BEGIN LIFTING OUT IN THE
LATTER PART OF THE SHORT TERM PERIOD WITH PWATS DECREASING FROM
1.9-2.0 INCHES CURRENTLY TO 1.4-1.5 INCHES BY SATURDAY NIGHT.
THUS...THE BROAD RIDGING WILL SLOWLY BUILD BACK OVER THE AREA. POP
GRIDS FOR TONIGHT REFLECT THE DIURNAL TREND OF AFTERNOON
PRECIPITATION...BROADBRUSHED 20 POPS FOR LINGERING SHOWER ACTIVITY
THROUGH MID EVENING THEN TRENDING POPS TO THE COAST AND COASTAL
WATERS. MET/MAV GUIDANCE HAS TRENDED A LITTLE LESS POPS FOR SATURDAY
WITH THE HIGHER POPS OVER THE COASTAL WATERS AND HAVE TRENDED THIS
WAY WITH 20 POPS ALONG AND EAST OF HWY 281. POPS CONTINUE THE
DOWNWARD TREND SATURDAY NIGHT AND JUST OVER THE COASTAL WATERS.

LEE TROUGHING STRENGTHENS AS A S/W TROUGH MOVES ACROSS THE ROCKIES
AND CENTRAL PLAINS WHICH WILL HELP RATCHET UP THE WINDS TOMORROW
WITH HIGH PRESSURE OVER THE GULF. BREEZY SOUTHEAST WINDS EXPECTED
WITH GUSTS TO 25 MPH POSSIBLE. WITH INCREASING WINDS...DECREASING
SKY COVER...AND WARMING 850/925MB TEMPERATURES...HIGHS ON SATURDAY
WILL BE A DEGREE OR TWO WARMER OVER TODAY.

.LONG TERM /SUNDAY THROUGH FRIDAY/...THE REGION WILL REMAIN CAUGHT
BETWEEN THE STRONGEST CORES OF RIDGING TO THE WEST AND EAST
THROUGH THE UPCOMING WEEK. MOISTURE VALUES WILL DECREASE BY EARLY
IN THE WEEK...MAINLY WRAPPING MORE TO THE NE INTO EAST TEXAS AND
LOUISIANA...AND INTO THE EXPECTED TROPICAL DEVELOPMENT IN THE
EPAC. WITH PW VALUES REMAINING BELOW 1.6 FOR MOST OF THE
EXTENDED...WILL BE HARD-PRESSED TO GET CONVECTIVE ACTIVITY TO FORM
ON THE SEABREEZE. HAVE LEFT SOME GHOST POPS IN FOR THE SEABREEZE
AREAS EACH DAY...FOR THE VERY ISOLATED POPS THAT MAY BRIEFLY POP
UP DURING PEAK HEATING...BUT OVERALL WILL REMAIN DRY THROUGH THE
PERIOD. LESSENED POPS AND CLOUD COVER WILL HELP TEMPS INCREASE
INTO THE MID TO UPPER 90S.

&&

.MARINE...
NOW THROUGH SATURDAY NIGHT...SEAS WERE NEAR 4 FEET WITH SOUTHEAST
WINDS NEAR 12 KNOTS AT BUOY020 EARLY THIS AFTERNOON. MODERATE TO
STRONG SOUTHEAST WINDS WILL PREVAIL ACROSS THE LOWER TEXAS COASTAL
WATERS THIS PERIOD AS HIGH PRESSURE ACROSS THE GULF INTERACTS WITH
LOW PRESSURE ACROSS THE SOUTHERN PLAINS. WINDS HAVE UNDERACHIEVED
TODAY AS COMPARED TO FORECAST BUT STILL EXPECTED TO INCREASE THIS
EVENING AND OVERNIGHT. WILL MAINTAIN SCEC OVER THE COASTAL WATERS
TONIGHT AND WILL WATCH FOR SCA ACROSS THE 20-60NM WATERS LATER THIS
EVENING AND OVERNIGHT. SCEC WILL CONTINUE INTO SATURDAY AND SATURDAY
NIGHT WITH THE POSSIBILITY OF SCA FOR THE LAGUNA SATURDAY AND
OFFSHORE WATERS SATURDAY NIGHT.

SUNDAY THROUGH TUESDAY...EXPECT WINDS TO GRADUALLY IMPROVE THROUGH
MIDWEEK AS SFC HIGH ACROSS THE EASTERN GULF SHIFT WESTWARD ACROSS
THE NW GULF. PRESSURE GRADIENT WILL DECREASE...ALLOWING WINDS TO
RELAX FOR 15 TO 20KTS SUNDAY TO AROUND 10 KNOTS TUESDAY INTO
WEDNESDAY. THIS WILL LET SEAS FINALLY DROP BELOW 4 FEET AND BRING
BETTER BOATING CONDITIONS.
