Wind Advisory 5, NWS Brownsville, TX

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BROWNSVILLE TX
245 AM CST TUE FEB 5 2008

..DISCUSSION...TEMPERATURES WILL BE ABOVE NORMAL FOR THIS TIME OF
YEAR DUE TO THE SOUTHERLY FLOW OF AIR.  THE COMBINATION OF A LOW
PRESSURE SYSTEM MOVING ACROSS THE GREAT PLAINS AND HIGH PRESSURE
OVER THE GULF OF MEXICO WILL CAUSE STRONG SOUTHEAST WINDS OVER DEEP
SOUTH TEXAS ONCE AGAIN TODAY...HOWEVER WILL NOT BE QUITE AS STRONG
AS MONDAY DUE TO AN APPROACHING COLD FRONT.  A COLD FRONT WILL MOVE
THROUGH THE AREA TUESDAY NIGHT BEFORE MIDNIGHT CAUSING CLOUDS TO
INCREASE.  BREEZY NORTH WINDS...COOLER TEMPERATURES AND DECREASING
CLOUDINESS WILL BE THE RULE IN THE WAKE OF THIS SYSTEM TUESDAY NIGHT
AND WEDNESDAY. BRO SOUNDING LAST NIGHT SHOWED A PRECIP WATER OF 1.22
AND A K-INDEX OF 24.
&&

.MARINE...SEAS WERE NEAR 7 FEET WITH SOUTHEAST WINDS NEAR 23 KNOTS
AT BUOY020 EARLY THIS MORNING. PRESSURE GRADIENT REMAINS TIGHT
ACROSS THE COASTAL WATERS SO WILL CONTINUE SCEC FOR THE LAGUNA MADRE
TODAY AND EXTEND THE SCA OFFSHORE THROUGH EARLY AFTERNOON BEFORE A
PREFRONTAL TROUGH APPROACHES THE LOWER TX COAST AND ALLOWS THE
PRESSURE GRADIENT TO RELAX. WINDS AND SEAS SHOULD DIMINISH EARLY
THIS EVENING BEFORE THE COLD FRONT MOVES INTO THE COASTAL WATERS.
WINDS WILL SHIFT TO THE NORTHWEST AND INCREASE TONIGHT AND SMALL
CRAFT ADVISORIES WILL BE NEEDED TONIGHT INTO WEDNESDAY AS A RESULT.
SEAS WILL DIMINISH WED NIGHT AS THE PRESSURE GRADIENT RELAXES AND
WINDS DIMINISH AND VEER TO THE NORTHEAST. A SURFACE TROUGH/WEAK COLD
FRONT IS PROGGED TO MOVE INTO EAST TX THURSDAY. THIS WILL PRODUCE A
WEAK PRESSURE GRADIENT ACROSS THE COASTAL WATERS. ANOTHER TROUGH IS
EXPECTED TO DEVELOP OVER NORTH TX FRIDAY AND WINDS SHOULD INCREASE
SLIGHTLY FROM THE SOUTH AS A RESULT. WINDS ARE EXPECTED TO BACK TO
THE EAST SATURDAY AS HIGH PRESSURE IS PROGGED TO BUILD INTO EAST TX
IN THE WAKE OF A FRONTAL SYSTEM OVER THE NORTHEAST UNITED STATES.
&&

.AVIATION...SATELLITE IMAGES AND SURFACE OBSERVATIONS INDICATE LOW
CLOUDS ACROSS CENTRAL PORTIONS OF DEEP SOUTH TX AS WELL AS ALONG THE
LOWER TX COAST EARLY THIS MORNING. CEILINGS WERE NEAR 1100FT AT KPIL
TO NEAR 1300FT AT KMFE. VAD WINDS INDICATED A STRONG LOW LEVEL JET
ACROSS THE LOWER TX COAST WITH MAX WINDS OF 52KTS AT 3000FT. THIS IS
PRODUCING SOME LOW LEVEL SHEAR AND THIS WILL PERSIST UNTIL THE LOW
LEVEL JET MOVES EASTWARD TODAY AS A PREFRONTAL TROUGH MOVES INTO THE
CWA THIS AFTERNOON. MVFR CEILINGS SHOULD IMPROVE AFTER 15Z AS WINDS
VEER TO THE SOUTH. VFR CONDITIONS SHOULD PREVAIL UNTIL 03Z WEDNESDAY
AS SOME LOW LEVEL MOISTURE WILL POOL ALONG A COLD FRONT THAT MOVES
THROUGH THE LOWER RIO GRANDE VALLEY LATER TONIGHT.
