AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BROWNSVILLE TX
326 AM CST FRI JAN 14 2011

.SHORT TERM /TODAY THROUGH 6 PM SATURDAY/...CHALLENGING FORECAST
FOR TEMPERATURES AND RAIN CHANCES THE NEXT COUPLE OF DAYS AS THE
COMBINATION OF A WEAK COASTAL TROUGH AND A 500MB LOW DEVELOPING
ACROSS NEW MEXICO TODAY AND DROPPING SOUTHWARD INTO WEST TEXAS AND
NORTHERN MEXICO TONIGHT PROVIDES QUITE A BIT OF UNCERTAINTY AS TO
WHEN TEMPERATURES WILL WARM AND WHEN RAIN CHANCES WILL BEGIN TO
INCREASE ACROSS THE LOWER RIO GRANDE VALLEY. BOTH THE NAM AND GFS
CONTINUE TO PROG HIGH RELATIVE HUMIDITY AT 850MB ACROSS THE AREA
TODAY THROUGH SATURDAY. THIS WILL LIKELY CONTINUE TO PROVIDE
OVERCAST CONDITIONS LIMITING DIURNAL HEATING. THE NAM SEEMS TO
HAVE A BETTER HANDLE ON THE COASTAL TROUGH THAN THE GFS AND THIS
MODEL SOLUTION WOULD PROVIDE HIGHER RAIN CHANCES ACROSS THE
COASTAL SECTIONS OF THE CWA AS A RESULT. WITH WEST TO NORTHWEST
WINDS ACROSS THE AREA...TEMPERATURES WILL STRUGGLE TO REBOUND
TODAY FROM CURRENT READINGS BUT THE SHALLOW AIRMASS SHOULD BEGIN
TO MODIFY SOMEWHAT AS THE MARINE LAYER ADVECTS ACROSS THE COASTAL
SECTIONS. AS THE AIRMASS MODIFIES TONIGHT INTO
SATURDAY...TEMPERATURES SHOULD GRADUALLY WARM AND COULD BE MUCH
WARMER IF MORE OF AN ONSHORE FLOW DEVELOPS ACROSS THE CWA AS
ADVERTISED BY THE GFS. WILL INCREASE RAIN CHANCES TONIGHT INTO
SATURDAY AS THE 500MB LOW MAKES IT WAY TOWARDS THE BIG BEND AREA
SAT AFTERNOON WITH LIGHT RAIN OR DRIZZLE BECOMING MORE CONVECTIVE
IN NATURE LATE TONIGHT INTO SATURDAY AS CONVERGENCE INCREASES
ACROSS THE LOWER TX COAST AND LAPSE RATES STEEPEN ENOUGH FOR
ELEVATED SHOWERS AND THUNDERSTORMS TO DEVELOP.
&&

.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...EXTENDED PERIOD
WILL BEGIN WITH THE CUTOFF LOW SLOWLY DIVING JUST TO THE
WEST...WITH BUILDING DYNAMICS SETTLING INTO PLACE OUT AHEAD OF IT
ACROSS SOUTH TEXAS. STILL LOOKING FOR A GOOD CHANCE FOR SHOWERS
AND THUNDERSTORMS SATURDAY NIGHT INTO SUNDAY MORNING...WITH
GRADUAL IMPROVEMENTS SUNDAY AFTERNOON. NOT STRONG THUNDERSTORMS
FORECAST WITH THIS PASSAGE. DRIER AIR MOVING IN BEHIND THE
MIDLEVEL IMPULSE WILL FINALLY BRING SUNNIER SKIES AND WARMER TEMPS
TO THE REGION MONDAY AND TUESDAY. THE NEXT MIDLEVEL IMPULSE WILL
SWEEP THROUGH NORTH TEXAS TUESDAY...DRAGGING A WEAK FRONT THROUGH
TEXAS INTO THE REGION TUESDAY NIGHT. MOST OF THE COLD AIR WITH
THIS FRONT IS DEFLECTING MORE TO THE EASTERN US...SO THE COOLDOWN
FOR WEDNESDAY WILL BE MINIMAL...MORE NOTICEABLE WITH LOWS ABOUT 5
DEGREES LOWER THAN MONDAY NIGHT. ONSHORE FLOW PROMPTLY RETURNS
LATER WEDNESDAY...WITH REGION WARMING BACK ABOVE NORMAL. THE NEXT
SURGE OF HIGH PRESSURE MOVES IN THURSDAY NIGHT. MODELS ARE ALSO
SHOWING ANOTHER COASTAL TROUGH FORMING UP JUST OFFSHORE. WITH THE
SFC HIGH TO THE NORTH...MODERATE EASTERLY SFC WINDS WILL ENSUE.
WINDS ALOFT WILL BE FROM DUE WEST WILL SIGNAL THE RETURN TO LOW
CLOUDS AND ISENTROPIC LIFT LIGHT RAIN/DRIZZLE.

&&

.AVIATION...
SATELLITE IMAGES AND SURFACE OBSERVATIONS INDICATE LOW CLOUDS
ACROSS DEEP SOUTH TX THIS MORNING AS OVERRUNNING CONTINUES TO
PROVIDE OVERCAST CONDITIONS ACROSS THE CWA. CEILINGS WERE NEAR
300FT AT KT65 TO NEAR 3300FT AT KSPL. VISIBILITIES WERE NEAR 1
1/2SM WITH FOG/MIST AT KAPY TO NEAR 5SM WITH FOG/MIST AT
KHRL...KPIL...AND KEBG. EXPECT MVFR TO LIFR CONDITIONS TO PREVAIL
THROUGH 15Z AS HIGH PRESSURE ACROSS THE WESTERN PORTIONS OF THE
LOWER RIO GRANDE VALLEY AND A WEAK COASTAL TROUGH OFFSHORE THE
LOWER TX COAST CONTINUES TO PROVIDE OVERRUNNING WITH LIGHT DRIZZLE
OR MIST. MVFR TO IFR CONDITIONS WILL LIKELY PREVAIL TODAY THROUGH
TONIGHT AS THE COASTAL TROUGH PROVIDES CONVERGENCE OF LOW TO MID
LEVEL MOISTURE ACROSS THE COASTAL SECTIONS OF THE CWA.

&&

.MARINE...
TODAY THROUGH 6 PM SATURDAY...SEAS WERE NEAR 5 FEET WITH EAST WINDS
NEAR 17 KNOTS AT BUOY020 EARLY THIS MORNING. A WEAK COASTAL TROUGH
OFFSHORE THE LOWER TEXAS COAST THIS MORNING WILL PROVIDE LIGHT
OFFSHORE WINDS ACROSS THE LOWER TX COAST AND MODERATE EAST TO
SOUTHEAST WINDS FAR OFFSHORE THE LOWER TX COAST TODAY. WILL WORD
SCEC FOR THE 20-60NM FOR THIS AFTERNOON BUT SMALL CRAFT ADVISORIES
WILL LIKELY BE NEEDED FOR THE OFFSHORE TONIGHT IF NOT SOONER AS THE
PRESSURE GRADIENT CONTINUES TO STRENGTHEN ACROSS THE WESTERN GULF OF
MEXICO. MODERATE TO STRONG SOUTHEAST WINDS WILL LIKELY PREVAIL
ACROSS THE OFFSHORE WATERS SATURDAY AS THE COASTAL TROUGH BECOMES
BETTER DEFINED ACROSS THE LOWER TX COAST.

SATURDAY NIGHT THROUGH TUESDAY...SHOWERS AND A FEW THUNDERSTORMS
WILL CONTINUE AT THE BEGINNING OF THE PERIOD AS A MIDLEVEL IMPULSE
MOVES ACROSS SOUTH TEXAS. THIS WILL ALSO PUSH THE COASTAL TROUGH
OUT TO SEAS AND DISSIPATE IT...ALLOWING ONSHORE FLOW TO DECREASE.
ADVISORIES MAY BE NEEDED THROUGH SUNDAY MORNING BEFORE WINDS CAN
LOWER TO 10 TO 15 KNOTS AND SEAS CAN REDUCE TO 5 FEET. MODEST
CONDITIONS WILL CONTINUE THROUGH TUESDAY...WHEN THE NEXT FRONT
SWEEPS THROUGH. WINDS WILL SWITCH BACK TO THE NORTH AND INCREASE
TO 20 KNOTS. SEAS WILL RESPOND...INCREASING BACK TO 7 TO 8 FEET
OFFSHORE.
