AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE BROWNSVILLE TX
1138 AM CST MON DEC 24 2012

.DISCUSSION...UPDATED FOR LATEST AVIATION DISCUSSION BELOW.
&&

.AVIATION...SURFACE WINDS ARE EXPECTED TO BRIEFLY INCREASE TO
BREEZY LEVELS THIS AFTERNOON BEFORE DIMINISHING THIS EVENING...
WITH ANOTHER INCREASE EXPECTED DURING THE OVERNIGHT HOURS AS A
FRONTAL AND LOW PRESSURE SYSTEM MOVES CLOSER TO DEEP SOUTH TEXAS
AND THE RIO GRANDE VALLEY. A THICK DECK OF CIRRUS IS LIKELY TO
PERSIST THROUGH THE OVERNIGHT HOURS. TOMORROW...WINDS WILL VEER
AS THE FRONT APPROACHES AND MOVES FROM WEST TO EAST THROUGH THE
AREA.
&&

.PREV DISCUSSION... /ISSUED 501 AM CST MON DEC 24 2012/

DISCUSSION...UPDATED FOR LATEST AVIATION DISCUSSION BELOW.

AVIATION...STILL AN OUTSIDE CHANCE FOR MVFR VIS THE FIRST COUPLE
OF HOURS OF THE TAF PERIOD WITH LIGHT/CALM WINDS BUT CONFIDENCE
DECREASING RAPIDLY AND HAVE LEFT OUT OF THE TAFS. THEREFORE...VFR
THIS TAF CYCLE WITH INCREASING WINDS AS LEE TROUGHING STRENGTHENS
TO OUR WEST/NORTH. HIGH CLOUDS WILL CONTINUE TO STREAM IN FROM
MEXICO AND WILL THICKEN TODAY AS SUBTROPICAL JET BRINGS IN
MOISTURE SHIFTS SOUTHWARD OVER THE AREA. TONIGHT...WINDS WILL
REAMIN UP AOA 8-11 KNOTS WHICH WILL HINDER FOG FORMATION ACROSS
DEEP SOUTH TEXAS.

PREV DISCUSSION... /ISSUED 400 AM CST MON DEC 24 2012/

SHORT TERM /TODAY THROUGH TUESDAY/...COLD FRONT STILL ON TRACK TO
MOVE ACROSS DEEP SOUTH TEXAS ON CHRISTMAS DAY. BEFORE
THIS...SUBTROPICAL JET WILL SHIFT SOUTHWARD THROUGH THE DAY TODAY
WITH MID/HIGH CLOUDS MOVING SOUTH ALONG WITH IT. SKY CONDITION WILL
BE PARTLY CLOUDY WITH MORE SUN THE FURTHER NORTH YOU ARE LOCATED.
MAXES TODAY ARE NUDGED UP A DEGREE OR TWO BASED ON SLIGHTLY WARMER
850MB TEMPERATURES. WITH INCREASING LEE TROUGHING TO OUR
WEST...WINDS WILL BE SLIGHTLY HIGHER THAN TODAY FROM THE SOUTHEAST.
BY MONDAY NIGHT...UPPER LEVEL TROUGH WILL MOVE ACROSS THE SOUTHERN
ROCKIES AND EMERGE INTO NORTHERN TEXAS. PRESSURE GRADIENT CONTINUES
TO STRENGTHEN OVERNIGHT WITH WINDS STAYING AROUND 8-12 KNOTS AND
WINDS BACKING TO THE SOUTHEAST AHEAD OF THE SURFACE LOW PRESSURE
SYSTEM. COLD FRONT MOVES ACROSS THE CWA CHRISTMAS DAY...FIRST ACROSS
THE NORTHWESTERN SECTIONS AFTER DAYBREAK AND THROUGH THE LOWER
VALLEY BY EARLY AFTERNOON. 850-700MB FLOW WILL TURN MORE WESTERLY
AND ADVECT VERY DRY AIR ACROSS DEEP SOUTH TEXAS WITH DEW POINT
DEPRESSIONS APPROACHING 40C IN SOME LOCATIONS. COUPLE THIS WITH WEAK
MOISTURE RETURN AND THIS SPELLS LITTLE CHANCE FOR PRECIPITATION. THE
COASTAL WATERS HAS THE BEST CHANCE FOR PRECIPITATION AND EVEN THAT
ISN/T A GOOD CHANCE. WHAT THIS DRY LOW/MID LEVEL AIR MEANS IS LOW
SURFACE RH VALUES BEHIND THE FRONT WITH MID TEENS EXPECTED ACROSS
ALL COUNTIES EXCEPT WILLACY/CAMERON COUNTY WHERE RH VALUES WILL BE
20% OR HIGHER. COUPLE THIS WITH INCREASED SURFACE/20 FOOT WINDS AND
THAT MEANS CRITICAL FIRE WEATHER LEVELS. HAVE ISSUED RED FLAG
WARNING ACROSS ALL EXCEPT CAMERON AND WILLACY COUNTIES TUESDAY
AFTERNOON AND WILL HANDLE THOSE TWO COUNTIES WITH EXISTING FIRE
WEATHER WATCH. MAXES ON TUESDAY WILL BE WARMER IN THE LOWER VALLEY
AHEAD OF THE FRONT WITH COOLER TEMPERATURES BEHIND THE FRONT.

LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/...A COOL NIGHT WILL BE IN
STORE TUESDAY NIGHT AFTER A COLD FRONT MOVES THROUGH TUESDAY DURING
THE DAY. THE TIMING OF THE FRONT WILL PUT THE KIBOSH ON EXCESSIVE
MID AFTERNOON HIGH TEMPERATURES TUESDAY AND WILL INITIATE A GRADUAL
DECLINATION IN TEMPS THROUGH WEDNESDAY MORNING. MODERATE NORTHWEST
TO NORTH WINDS WILL COMBINE WITH CLEAR SKIES...AND LOW TEMPERATURES
WILL RANGE FROM NEAR 40 AT BRO TO NEAR 34 AT HEBBRONVILLE. INHERITED
TEMPS SEEMED REASONABLE...WITH ONLY MINOR DRIFT IN PREVIOUS GUIDANCE.
THUS LOWERED TEMPERATURES A DEGREE BUT OTHERWISE WENT WITH PREVIOUS
THINKING. WEDNESDAY WILL BE CLEAR AND COOL WITH TEMPS STRUGGLING TO
MAKE IT OUT OF THE 50S. NO PRECIPITATION OF ANY SIGNIFICANCE IS IN
THE CARDS.

A REPEAT COLD NIGHT WILL OCCUR WEDNESDAY NIGHT...WITH LOW TEMPS A
DEGREE OR TWO COLDER THAN TUESDAY NIGHT. A FEW FREEZING MARKS ACROSS
THE NORTHERN TIER WILL BE WITHIN REACH UNDER MOSTLY CLEAR SKIES AND
LIGHT WINDS. INHERITED TEMPS AGAIN LOOKED GOOD. TEMPS WILL MODIFY
UPWARD THURSDAY AND FRIDAY...WITH WINDS SHIFTING TO SOUTHEAST AND
CLOUD COVER INCREASING. IN THE MEAN TIME...THE NEXT MID LEVEL SHORT
WAVE TROUGH WILL BE DEEPENING OVER THE FOUR CORNERS AREA. MID LEVEL
FLOW BACKING TO SOUTHWEST AND INCREASING SOUTHEAST SURFACE WINDS
WILL BRING THE THREAT OF ISOLATED SHOWERS TO THE MARINE AREAS AND
THE COASTAL COUNTIES THURSDAY THROUGH FRIDAY NIGHT.

THE AFOREMENTIONED TROUGH WILL KICK OUT ON FRIDAY AND WILL SWING
OVER NORTH TEXAS ON SATURDAY...COINCIDENT WITH A SURFACE FRONT
ARRIVING IN THE LOWER VALLEY SATURDAY MORNING. ISOLATED SHOWERS WILL
BE POSSIBLE ALONG THE FRONT SATURDAY MORNING...WITH SOME CLEARING
AND BREEZY NORTH WINDS SATURDAY AFTERNOON. HIGH TEMPS SATURDAY WILL
STRUGGLE TO GET OUT OF THE 60S...WHILE 40S WILL BE THE RULE ACROSS
DEEP SOUTH TEXAS SATURDAY NIGHT. A SEASONAL DAY WITH NEAR NORMAL
TEMPS WILL BE ON TAP FOR SUNDAY...WITH MOSTLY SUNNY TO PARTLY CLOUDY
SKIES MAKING IT A NEAR CHAMBER OF COMMERCE DAY.

MARINE...
TODAY THROUGH TUESDAY...BUOY 020 REPORTED WINDS OF 14 KNOTS
GUSTING TO 18 KNOTS WITH 5 FOOT SEAS AT 09Z. WINDS AND SEAS
EXPECTED TO DECREASE SLIGHTLY TODAY BEFORE INCREASING TONIGHT AND
TUESDAY AHEAD OF A LOW PRESSURE SYSTEM THAT WILL SWEEP A COLD
FRONT THROUGH THE COASTAL WATERS TUESDAY. SCEC CONDITIONS WILL
RETURN MONDAY NIGHT WITH SCA CONDITIONS POSSIBLE TUESDAY. THERE IS
A SLIGHT CHANCE FOR SHOWERS...MAINLY FOR THE OFFSHORE WATERS
TUESDAY AFTERNOON.

TUESDAY NIGHT THROUGH FRIDAY...A MID LEVEL SHORT WAVE TROUGH AND
ASSOCIATED SURFACE COLD FRONT ARE SCHEDULED TO SWING ACROSS TEXAS
TUESDAY...WITH FRONTAL PASSAGE ACROSS THE LOCAL CWA AND THE LOWER
TEXAS COAST IN THE BOOKS BY THE BEGINNING OF THE LONG TERM. STRONG
NORTH OF NORTHWEST WINDS WILL GUST TO GALE FORCE TUESDAY EVE. THE
GFS DEVELOPS A DEEPER SURFACE LOW THAN THE NAM UNDER THE MID LEVEL
TROUGH...RESULTING IN SLIGHTLY STRONGER MARINE WINDS RIGHT BEHIND
THE FRONT...BUT IN EITHER CASE A FEW HOURS OF POST FRONT GALE FORCE
GUSTS NOW HAVE AN ABOVE AVERAGE LEVEL OF CERTAINTY. WAVE HEIGHTS
OFFSHORE WILL BUILD TO 12 FEET TUESDAY NIGHT. CONDITIONS WILL THEN
IMPROVE FAIRLY RAPIDLY ON WEDNESDAY AS HIGH PRESSURE SPREADS OVER
THE AREA...WITH SMALL CRAFT ADVISORY CONDITIONS BEING DISMISSED BY
WEDNESDAY AFTERNOON. SOUTHEAST RETURN FLOW WILL BE BACK BY THURSDAY
WITH LOW SEAS. WEST TEXAS LOW PRESSURE WILL HELP INCREASE WINDS TO
EXERCISE CAUTION STRENGTH THURSDAY NIGHT...WITH MODERATE SEAS. HIGH
PRESSURE WILL MOVE INTO TX ON FRIDAY AS ANOTHER FRONT DRAWS NEAR...
WITH LIGHT WINDS SHIFTING TO NORTH AND BECOMING STRONG LATE FRIDAY
NIGHT TO EARLY SATURDAY MORNING. AN ADVISORY FOR THE GULF MAY BE
