SOUTHEASTERLY WINDS WILL CONTINUE ACROSS THE COASTAL COUNTIES

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BROWNSVILLE TX
406 AM CDT FRI APR 22 2011

.SHORT TERM /TODAY THROUGH SATURDAY/...THE RIO GRANDE VALLEY WIND
TO CRANK UP ANOTHER GEAR TODAY WITH A WIND ADVISORY TO BE IN
EFFECT FOR THE THREE EASTERN COUNTIES TODAY. PRESSURE GRADIENT
STRENGTHENS AS LOW PRESSURE DEEPENS OVER THE SOUTHERN PLAINS. THE
APPROACH OF A SHORT WAVE TROUGH ACROSS THE ROCKIES TO INDUCE A LOW
PRESSURE AREAS ALONG THE TRIPLE POINT OF A COLD FRONT AND THE WEST
TEXAS DRY LINE. LOW LEVEL JET IS FORECAST TO STRENGTHEN TO 40
KNOTS AROUND SUNRISE AND MAINTAIN CLOSE TO THIS SPEED THROUGH 18Z.
AS THE MORNING STRATUS BREAKS (IT IS SOMEWHAT PATCHY AS OF THIS
WRITING) AND TEMPERATURES RISE NEAR FULL MIXING TO TAKE PLACE.
PEAK WINDS EXPECTED BETWEEN 10 AND 4 PM WITH GUSTS UP TO 40 OR 45
MPH POSSIBLE. HIDALGO COUNTY ON THE FENCE FOR ADVISORY BUT EASTERN
AREA COULD SEE THE STRONGER WINDS. THE WELL MIXED ATMOSPHERE AND
EXCEEDINGLY DRY SOIL WILL PROVIDE THE VALLEY AND ALL OF DEEP SOUTH
TEXAS WITH SUMMER LIKE TEMPERATURES ONCE AGAIN. MODEL GUIDANCE
REMAINS SLIGHTLY BELOW THE GOING FORECAST WITH THE NAM REMAIN THE
WARMEST.

WARM AND SULTRY AGAIN TONIGHT WITH LITTLE RELIEF FROM THE WINDS.
WILL KEEP BREEZY CONDITIONS IN TONIGHT WITH THUNDERSTORMS OVER WEST
AND NORTH TEXAS KEEPING THE GRADIENT ACROSS THE LOWER COASTAL AREAS
STRONG. OVERNIGHT LOWS WILL AVERAGE NEAR GUIDANCE BUT AROUND 10
DEGREES ABOVE SEASONAL AVERAGES WHICH SHOULD BE IN THE MID 60S.

SATURDAY WILL BE JUST A BIT TEMPERATE WITH WINDS SLACKEN OFF FROM
ADVISORY LEVELS AND TEMPERATURES DROPPING OFF A FEW DEGREES. MODELS
SUGGEST A WEAK BREAK IN THE UPPER HIGH PRESSURE RIDGE AS THE COLD
FRONT TO THE NORTH HELPS IN THE WEAKENING PROCESS. BELIEVE GFS IS
WAY TO BULLISH DROPPING TEMPERATURES IN THE BROWNSVILLE AREA TO THE
LOWER 80S. THE STIFF SOUTH WIND AND AFTERNOON SUNSHINE SHOULD WARM
TEMPERATURES TO AT LEAST THE UPPER 80S TO MID 90S ACROSS THE REGION.
WILL CONTINUE TO TREND WITH THE WARMER NAM NUMBERS ACROSS THE BOARD.

.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...BREEZY SOUTHEAST
WINDS WILL DOMINATE THE EXTENDED WITH HIGH PRESSURE ACROSS THE
GULF AND LOW PRESSURE AREAS SWEEPING ACROSS NORTH TEXAS. GENERALLY
WEST TO SOUTHWEST WINDS ALOFT WILL CONTINUE TO STEER COLD FRONT
AWAY FROM SOUTH TEXAS. THERE WILL BE ENOUGH STEERING IN THE UPPER
FLOW TO HELP THE DRYLINE INTO THE FAR WESTERN COUNTIES EACH
DAY...BRINGING MUCH LIGHTER WINDS AND VERY DRY CONDITIONS. MODELS
ARE GETTING A LITTLE BETTER ORGANIZED ON A LARGE-SCALE TROUGH
DIVING ACROSS THE CENTRAL US EARLY NEXT WEEK. THIS WILL TURN WINDS
ALOFT TO THE NORTHWEST AND HELP PUSH A FRONTAL BOUNDARY INTO THE
REGION TUESDAY OR WEDNESDAY. WHILE THE FRONT ITSELF LIKELY WONT
HAVE ENOUGH DYNAMICS TO OVERCOME THE VERY STRONG CAPPING
INVERSION...THUNDERSTORMS ACROSS THE MOUNTAINS IN MEXICO MAY BE
ABLE TO TAP THE INSTABILITY ALONG THE FRONT AND TRAVEL EAST INTO
THE REGION. THIS WOULD PUT THE BEST CHANCES FOR RAIN IN THE FAR
WESTERN COUNTIES. TIMING IS STILL AN ISSUE...BUT THE SOLUTION IS
COMING MORE INTO ALIGNMENT.

&&

.MARINE...TODAY THROUGH SATURDAY...ALL COASTAL WATERS INCLUDING THE
LAGUNA TO BE UNDER A SMALL CRAFT ADVISORY TODAY. STRENGTHENING
PRESSURE GRADIENT THIS MORNING WILL PICK UP THE WINDS ANOTHER NOTCH
FROM WHAT WAS OBSERVED OVERNIGHT. LOW PRESSURE TO DEEPEN OVER NORTH
TEXAS WITH SURFACE LOW PRESSURE DEVELOPING OVER NORTHEAST MEXICO.
WATER TEMPERATURES ARE BECOMING WARM ENOUGH TO ALLOW FOR AFTERNOON
MIXING OF THE STRONGER WINDS ALOFT TO REACH THE WATER SURFACE AND TO
KICK UP THE WINDS OVERNIGHT. WINDS TO PEAK THROUGH THE MORNING WITH
GUSTS POSSIBLY APPROACHING GALE FORCE OVER SOME AREAS OF THE LAGUNA.
PERSISTENT WINDS TO KEEP SEAS BUILDING OVER THE NEXT 24 HOURS WITH
SEAS NEARING 8 FEET. SCA CONDITIONS LIKELY TO CONTINUE TONIGHT WITH
THE GRADIENT SLOW TO RELAX. SIMILAR CONDITIONS ON SATURDAY BUT NOT
AS STRONG ON THE GUSTS.

SATURDAY NIGHT THROUGH TUESDAY...BREEZY SOUTHEAST WINDS WILL
CONTINUE THROUGH THE WEEKEND...WITH SMALL CRAFT ADVISORIES LIKELY
THROUGH THE FORECAST PERIOD. WINDS WILL STAY RIGHT AROUND 20
KNOTS...KEEPING SEAS AGITATED AT 5 TO 7 FEET. A LATE SEASON COLD
FRONT IS EXPECTED TO CROSS THE NORTHWEST GULF SOMETIME IN THE
MONDAY NIGHT TO WEDNESDAY TIME FRAME. TIMING IS STILL AN
ISSUE...BUT A WIND SHIFT IS LOOKING LIKELY WITH THE PASSAGE.
