AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BROWNSVILLE TX
330 AM CDT SUN APR 16 2006

.DISCUSSION...THE MAIN CONCERN IN THE SHORT TERM FOR TODAY WILL BE
ANTICIPATED SURFACE WINDS. CURRENTLY...THE KBRO VWP SHOWS A VERY
STRONG LLJ IN PLACE OVER THE REGION THIS MORNING RANGING FROM 40 TO
50 KNOTS FROM THE SOUTH. ALTHOUGH THE RADAR MAY BE OVER-ESTIMATING
THE STRENGTH OF THE LLJ...THE SURFACE WINDS THROUGHOUT THE EARLY
MORNING HOURS AROUND THE LOWER RGV SEEM TO BE VERIFYING THE PRESENCE
OF SOME TYPE OF JET ALOFT WITH SURFACE WINDS RANGING FROM 15 TO 20
KNOTS OVER THE LAST SEVERAL HOURS. THE LLJ SHOULD BEGIN TO BREAK
DOWN LATER TODAY AS THE 500 MB CLOSED LOW OVER THE UPPER MIDWEST
SHIFTS FURTHER EAST ALLOWING RIDGING TO DOMINATE THE REGION LATER
TONIGHT AND INTO MONDAY.  A MODERATE TO STRONG SOUTHERLY GRADIENT
FLOW WILL PERSIST IN THE SHORT TERM AS ANOTHER 500 MILLIBAR TROUGH
DIGS INTO THE CENTRAL U.S. ON MONDAY WHICH WILL REDEVELOP ANOTHER
SURFACE LOW PRESSURE SYSTEM FOR MONDAY AND TUESDAY.  WHILE AN ACTIVE
NORTHERN STREAM OF THE 500 MB FLOW PATTERN PERSISTS...AN OVERALL HOT
AND DRY PATTERN WILL CONTINUE OVER DEEP SOUTH TEXAS THROUGH MIDWEEK
WITH 1000-500 MB THICKNESS LEVELS RANGING IN THE 580-585 DM AREA
THROUGH TUESDAY WHICH WILL KEEP SOUTH CENTRAL AND DEEP SOUTH TEXAS
AS THE HOT SPOTS OF THE NATION IN THE SHORT TERM.  MAV AND MET
FORECAST TEMPS IN THE SHORT TERM SHOW GOOD MODEL TO MODEL AND RUN TO
RUN CONTINUITY AND WILL NOT DEVIATE TOO MUCH FROM THIS TREND.  THE
LONGER TERM MODELS SHOWS THE HIGH 1000-500 MB THICKNESSES WEAKENING
DURING THE LATTER HALF OF THIS WEEK SHOWING A LITTLE BIT OF A BREAK
FROM THE ABOVE NORMAL TEMPS.  ALSO...SOME PERIODIC 500 MB VORTICIES
BEGIN TO ADVECT OVER THE REGION LATE THURSDAY INTO FRIDAY AS THE
RIDGING BREAKS DOWN.  THIS WILL COMBINE WITH SOME BETTER MOISTURE
ADVECTION TO INCREASE POPS A LITTLE IN THE LONGER TERM.  BELIEVE
THAT THE MOISTURE MAY BE TOO LIMITED FOR ANY WIDESPREAD RAINFALL AND
WILL COVER WITH SLIGHT CHANCE POPS FOR THE MOMENT.  AS THE 500
MILLIBAR RIDGING BEGINS TO WEAKEN...WILL GO WITH TEMPS CLOSE TO
CLIMO IN THE LATER HALF OF THE FORECAST PERIOD.
&&

.MARINE...42020 HAS BEEN REPORTING SUSTAINED WINDS NEAR 20 KNOTS AND
6-7 FOOT WAVES DURING THE NIGHT. MODELS MAINTAIN FAIRLY STRONG
GRADIENT THROUGH TODAY WITH A WEAKER GRADIENT PROGGED BY LATE
TONIGHT WITH APPROACH OF SURFACE TROUGH INTO CENTRAL TEXAS. SCA WILL
BE ISSUED FOR TODAY FOR NOT ONLY OFFSHORE WATERS...BUT THE LAGUNA
MADRE AS WELL GIVEN 50 KNOT WINDS ON THE BRO VWP. GRADIENT WILL THEN
STAY RELAXED FOR THE NEXT FEW DAYS BUT WILL INCREASE LATE THIS WEEK
AS SHORT WAVE ENERGY SHOULD INDUCE LOW PRESSURE DEVELOPMENT OVER
SOUTHERN PLAINS. THIS WILL LIKELY PUT WINDS/SEAS NEAR SCA CRITERIA
BY LATE THURSDAY.
&&

.AVIATION...WINDS HAVE DIMINISHED AT AREA AIRPORTS TO NEAR 15
KNOTS...BUT WILL LIKELY BE ON THE INCREASE THIS MORNING. GIVEN THE
STRONG LOW LEVEL JET...MAY NEED TO HAVE LLWS IN THE TAFS DEPENDING
ON OBSERVATIONS OVER THE NEXT FEW HOURS.  VFR CONDITIONS LIKELY
THROUGH TONIGHT.
