AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BROWNSVILLE TX
415 AM CDT SUN MAR 16 2008

.DISCUSSION...IR AND WV SATL IMAGERY INDICATES THAT THE 500 MB
TROUGH DIGGING SOUTH ACROSS THE WEST COAST IS MAKING GOOD PROGRESS
TOWARDS THE U.S./MEXICO BORDER REGION. THE ECMWF/GFS AND NAM ARE IN
REASONABLE AGREEMENT IN THE TIMING AND STRENGTH OF THIS FEATURE AS
IT PUSHES EAST TOWARDS THE TX COASTLINE BY LATE TUES/EARLY WED. BOTH
THE ECMWF AND THE GFS PUSH THIS FEATURE THROUGH CENTRAL TX IN THE
00Z TO 12Z WED TIME FRAME. THIS TROUGH WILL ADVECT IN STRONG PV ON
TUES ALONG AND JUST BEHIND THE SURFACE FRONT THAT IS EXPECTED TO
MOVE THROUGH THE REGION ON TUES.  DESPITE THE STRONG UPPER LEVEL
DYNAMICS MOVING IN WITH THIS FEATURE...MEAN RH FIELDS FROM THE GFS
AND ECMWF REMAIN PRETTY LIMITED OVER DEEP SOUTH TX WITH THE BETTER
MOISTURE VALUES CONCENTRATED OVER MAINLY THE EASTERN HALF OF TX. SPC
HAS PLACED THE SOUTHERN EDGE OF THE DAY 2 SLGT RISK TO JUST SOUTH OF
LRD WITH THE DAY 3 SLGT RISK LOCATED JUST NORTHEAST OF THE BRO CWA
EXTENDING NORTHEAST OVER THE LOWER MISS RIVER VALLEY AREA. AS A
RESULT...WILL CONTINUE TO MENTION THE POTENTIAL FOR SVR WX FOR
MONDAY NIGHT INTO TUESDAY IN THE CURRENT HWO. THE SLOW EASTWARD
PROGRESSION OF THIS TROUGH AXIS WILL MAINTAIN A TIGHT PGF OVER THE
BRO CWA FROM TODAY THROUGH TUES. ACCORDINGLY...EXPECT CONDITIONS
NEAR OR EXCEEDING WIND ADVISORY LEVELS IN THE SHORT TERM DURING THE
DAYLIGHT HOURS. MAV AND MET TEMPS ARE IN GOOD AGREEMENT FOR THE MOST
PART WITH THE EXCEPTION OF TUES WHERE THE NAM PULLS THE SURFACE
FRONT THROUGH A LITTLE EARLIER THAN THE GFS. AS A RESULT...THE NAM
IS COOLER THAN THE MAV FOR TEMPS ON TUES. WILL STICK CLOSE TO THE
MAV/MET CONSENSUS FOR THE EARLY PERIODS AND WILL LEAN TOWARDS THE
WARMER MAV NUMBERS FOR TUES. THE INCREASING MOISTURE ADVECTION
COMING IN OFF OF THE GULF HAS PRODUCED A GOOD SC AND FOG DECK OVER
THE RERION. ASOS OBS AT THE BRO...PIL...HRL AND MFE HAVE REPORTED
PERIODIC DENSE FOG OVER THE LAST SEVERAL HOURS. HAVE ISSUED A DENSE
FOG ADVISORY FOR THE EASTERN THREE COUNTIES AS A RESULT. THIS SHOULD
BE PRETTY SHORT LIVED AND SHOULD DISSIPATE PRETTY QUICKLY AROUND
SUNRISE. AFTER THIS 500 MB TROUGH EXITS THE REGION LATE TUES/EARLY
WED A WARM AND DRY PATTERN WILL PREVAIL INTO THE 3 TO 7 DAY RANGE AS
WEAK TO MODERATE RIDGING WILL DOMINATE THE REGION. MEX TEMPS AND
POPS LOOK OK IN THE EXTENDED RANGE PERIOD WITH ABOVE NORMAL TEMPS
AND BELOW NORMAL POPS IN PLACE. RUN TO RUN CONSISENCY IN THE GFS MOS
OUTPUT IS OK.
&&

.FIRE WEATHER...HAVE UPGRADED THE FIRE WX WATCH TO A RED FLAG
WARNING FOR THE ENTIRE BRO CWA DUE TO THE COMBINATION OF INCREASING
SURFACE WINDS...LOW DEWPOINTS OVER THE WEST AND THE AMOUNT OF CURED
FUELS.
&&

.AVIATION...SATELLITE IMAGES AND SURFACE OBSERVATIONS CONTINUE TO
INDICATE FOG MOVING INLAND ACROSS THE EASTERN PORTIONS OF THE CWA
EARLY THIS MORNING. CEILINGS WERE NEAR 100FT AT KHRL/KMFE/KPIL TO
NEAR 300FT AT KBRO. VISIBILITIES WERE NEAR 1/4SM WITH FOG AT KMFE TO
NEAR 3SM WITH FOG AT KBRO. LIFR CONDITIONS TO PERSIST WITH THE FOG
THROUGH 15Z SUNDAY. CEILINGS AND VISIBILITIES SHOULD IMPROVE TO VFR
LEVELS AFTER 15Z AS THE FOG LIFTS WITH DIURNAL HEATING AND WINDS
VEER TO THE SOUTHEAST AND INCREASE AS THE PRESSURE GRADIENT
INCREASES ACROSS THE LOWER TX COAST. VFR CONDITIONS SHOULD PREVAIL
UNTIL LOW CEILINGS DEVELOP LATE TONIGHT.
&&

.MARINE...SEAS WERE NEAR 3 FEET WITH EAST WINDS NEAR 10 KNOTS AT
BUOY020 EARLY THIS MORNING. LOW PRESSURE OVER NEW MEXICO AND WEST
TEXAS WITH HIGH PRESSURE OVER THE EASTERN UNITED STATES WILL
INCREASE THE PRESSURE GRADIENT ACROSS THE COASTAL WATERS THIS
AFTERNOON. WINDS WILL VEER TO THE SOUTHEAST AND INCREASE TO 15 TO 25
KNOTS TODAY WITH SEAS BUILDING OFFSHORE LATE. HAVE ALREADY ISSUED
SCA FOR THE LAGUNA MADRE AND THE OFFSHORE WATERS AS A RESULT. THE
PRESSURE GRADIENT WILL CONTINUE TO INCREASE TONIGHT INTO MONDAY WITH
A LOW LEVEL JET DEVELOPING ACROSS THE LOWER TX COAST. VERY STRONG
SOUTHEAST WINDS WILL DEVELOP LATE TONIGHT INTO MONDAY WITH GUSTS TO
NEAR GALE FORCE LIKELY MON AFTERNOON. HAVE ISSUED A GALE WATCH FOR
THE COASTAL WATERS MONDAY AS A RESULT. SEAS WILL CONTINUE TO BUILD
OFFSHORE TO 6 TO 10 FEET TONIGHT AND 9 TO 11 FEET MONDAY WITH THE
INCREASE OF WINDS. THE STRONG SOUTHEAST WINDS WILL CONTINUE MON
NIGHT INTO EARLY TUESDAY BEFORE A STRONG PACIFIC COLD FRONT MOVES
OFFSHORE THE LOWER TX COAST TUES AFTERNOON BRINGING A LINE OF STRONG
TO SEVERE THUNDERSTORMS THROUGH THE COASTAL WATERS. WINDS WILL SHIFT
TO THE NORTHWEST AND INCREASE IN THE WAKE OF THE FRONT ALLOWING SEAS
TO FALL RAPIDLY OFFSHORE TUES EVENING BUT WILL INCREASE LATE TUES
NIGHT AS WINDS CONTINUE TO INCREASE FROM THE NORTHWEST. WINDS AND
SEAS SHOULD FINALLY DIMINISH WEDNESDAY AFTERNOON AS THE PRESSURE
GRADIENT BEGINS TO DECREASE WITH HIGH PRESSURE BUILDING INTO THE
WESTERN GULF OF MEXICO. WINDS WILL CONTINUE TO DIMINISH AND VEER TO
THE NORTHEAST AND EAST WED NIGHT INTO EARLY THURSDAY WITH THE RIDGE
MOVING EASTWARD. A EAST TO SOUTHEAST FLOW SHOULD PREVAIL THURSDAY
WITH HIGH PRESSURE ACROSS SOUTHEAST U.S. AND LOW PRESSURE DEVELOPING
ON THE LEE SIDE OF THE ROCKIES.
