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

&&

.AVIATION...MODEL GUIDANCE IS IN GENERAL AGREEMENT WITH CEILINGS
DECREASING TO MVFR AND EVEN IFR REST OF TONIGHT...WITH LIGHT TO
MODERATE FOG AT THE TAF SITES. A LOW PRESSURE TROUGH LIES JUST
OFFSHORE...A COASTAL TROUGH...WHICH IS FUNNELING OFFSHORE ISOLATED
SHOWERS NORTH. A DEW POINT GRADIENT LIES JUST INLAND OF THE TEXAS
COAST...WITH RELATIVELY JUICY DEW POINTS COMPARED TO THOSE FARTHER
INLAND. LIGHT WINDS AND INCREASING DEW POINTS WILL BE CONDUCIVE TO
LOW CEILINGS AND FOG FORMATION. A COLD FRONT WILL MOVE THROUGH THE
CWA AROUND MID DAY...WITH IMPROVED FLYING CONDITIONS AFTERWARD. A
FEW SHOWERS MAY ACCOMPANY THE FRONT. MODERTAE GUSTY NORTH WINDS
WILL DEVELOP THIS AFTERNOON IN THE WAKE OF THE FRONT. CLEARING
WILL BE INCOMPLETE HOWEVER...WITH SCT TO BKN MID LAYER CLOUDS
STILL LATE FRIDAY.

&&

.PREV DISCUSSION... /ISSUED 942 PM CST THU DEC 27 2012/

DISCUSSION...SURFACE OBSERVATIONS INDICATE THAT TEMPERATURES OVER
THE THREE WESTERN COUNTIES OF BRO CWA HAVE COOLED FASTER THAN
FORECAST THIS EVENING. MADE MINOR ADJUSTMENTS TO THE OVERNIGHT
LOWS OVER THE FAR WESTERN PORTIONS OF THE CWA. THE REST OF THE
FORECAST LOOKS GOOD.

PREV DISCUSSION... /ISSUED 608 PM CST THU DEC 27 2012/

DISCUSSION...UPDATED FOR LATEST AVIATION DISCUSSION BELOW.

AVIATION...SATELLITE IMAGES AND SURFACE OBSERVATIONS INDICATE LOW
AND HIGH CLOUDS OVER DEEP SOUTH TEXAS THIS EVENING. CEILINGS
RANGE FROM 2800FT AT KBKS TO 4700FT AT KPIL. EXPECT A MIX OF
VFR/MVFR CEILINGS THIS EVENING AS A WEAK COASTAL TROUGH CONTINUES
TO PROVIDE WEAK CONVERGENCE ACROSS THE LOWER TEXAS COAST. LIGHT
WINDS AND INCREASING DEWPOINTS WILL ALLOW CEILINGS TO LOWER LATER
THIS EVENING AND OVERNIGHT. PATCHY FOG IS ALSO POSSIBLE AFTER
MIDNIGHT TONIGHT. MVFR CONDITIONS EXPECTED TO DEVELOP AFTER 03Z
FRIDAY. A COLD FRONT WILL APPROACH AND MOVE THROUGH THE RIO GRANDE
VALLEY LATE FRIDAY MORNING INTO EARLY FRIDAY AFTERNOON. GUSTY
NORTHWEST WINDS WILL DEVELOP IN THE WAKE OF THE FRONT FRIDAY
AFTERNOON.

PREV DISCUSSION... /ISSUED 221 PM CST THU DEC 27 2012/

SHORT TERM /TONIGHT THROUGH FRIDAY NIGHT/...WEAK COASTAL TROUGH
ACROSS THE LOWER TEXAS COAST THIS AFTERNOON CONTINUES TO PROVIDE
SOUTHERLY WINDS OFFSHORE WITH LIGHT AND VARIABLE WINDS ACROSS THE
INLAND AREAS OF THE CWA. CLOUDS HAVE KEPT TEMPERATURES ON THE COOL
SIDE TODAY AND WILL KEEP TEMPERATURES FROM FALLING MUCH OVERNIGHT.
WITH TEMPS HOLDING STEADY TONIGHT...AREAS OF FOG ARE EXPECTED TO
DEVELOP LATE TONIGHT INTO EARLY FRIDAY BEFORE A COLD FRONT MOVES
THROUGH THE RIO GRANDE VALLEY FRI AFTERNOON. ISOLATED SHOWERS WILL
DEVELOP ACROSS THE COASTAL WATERS TONIGHT WITH THE WARM AIR
ADVECTION OFFSHORE AND DEVELOP ACROSS THE COASTAL SECTIONS OF THE
CWA EARLY FRIDAY BEFORE DRIER AND COOLER AIR FILTERS INTO THE AREA
FRI AFTERNOON. TEMPERATURES WILL FALL FRI NIGHT BUT WILL REMAIN
ABOVE FREEZING ACROSS THE NORTHERN PORTIONS OF THE CWA AS WINDS
REMAIN STRONG ENOUGH TO INHIBIT RADIATIONAL COOLING.

LONG TERM /SATURDAY THROUGH THURSDAY/...THE LONG TERM CONTINUES
TO BE DIFFICULT TO FIGURE OUT WITH A COMPLEX AND POSSIBLE
SIGNIFICANT SYSTEM CROSSING THE DESERT SOUTHWEST AND TEXAS FOR THE
HOLIDAY WEEKEND AND EARLY NEXT WEEK. MODELS CONTINUE TO EVOLVE
TOWARDS A SIMILAR SOLUTION BUT PLENTY OF DIFFERENCES RESIDE IN
STRENGTH AND TRACK. FORECAST CONFIDENCE IS BELOW AVERAGE AND MORE
ADJUSTMENTS EXPECTED THE NEXT FEW DAYS.

THE BEGINNING OF THE LONG TERM OR SATURDAY LOOKS TO BE FAIR WITH
SHORT WAVE RIDGING OVER SOUTH TEXAS. BELOW NORMAL TEMPERATURES ARE
FORECAST IN WAKE OF FRIDAY/S COLD FRONT. CLEAR SKIES AND COOL TO
COLD TEMPERATURES ARE EXPECTED SUNDAY MORNING BEFORE THE FORECAST
BEGINS TO DETERIORATE.

NO ONE MODEL IS SIMILAR BUT MOST ARE TRENDED TOWARDS A DEEPER
MERIDIONAL PATTERN WITH A BRIEF CUTOFF LOW DEVELOPING SOMEWHERE OFF
BAJA CA OR THE DESERT SOUTHWEST. THE ECMWF WAS THE MODEL OF
CHOICE WITH IT BEING THE MOST CONSISTENT AND BETWEEN THE MORE
PROGRESSIVE GFS AND THE SLOWER DEEPER CANADIAN. LOOKING FOR A DEEP
SOUTHWEST FLOW TO DEVELOP FROM SUNDAY THROUGH WEDNESDAY WITH
MOISTURE DEEPENING FROM BOTH THE PACIFIC AND GULF OF MEXICO. CHANCE
OF RAIN INCREASES THROUGH THE PERIOD WITH TUESDAY AND WEDNESDAY
LOOKING LIKE THE BEST DAYS AT THIS TIME WITH THE BEST DIVERGENT
FLOW AND WARM AIR ADVECTION COMBINING. COLD FRONT MOVES THROUGH ON
TUESDAY WITH SHALLOW AIR MASS TO BECOME ENTRENCHED WITH 850
SOUTHEAST FLOW STRENGTHEN WITH THE MAIN TROUGH HANGING BACK ACROSS
THE DESERT SOUTHWEST. IMPROVING CONDITIONS ARE EXPECTED BY
THURSDAY AS THE UPPER TROUGH FINALLY MAKE A MOVES EASTWARD AND
WEAKENS BUT IT MIGHT TAKE ALL DAY FOR THE VALLEY TO CLEAR. MORE
DETAILS AS THEY BECOME FOR CLEAR. STAY TUNED 2012 MAKE GO OUT LIKE
A WET LION.

MARINE...TONIGHT THROUGH FRIDAY NIGHT...SEAS WERE NEAR 4 FEET WITH
SOUTHEAST WINDS NEAR 19 KNOTS AT BUOY020 EARLY THIS AFTERNOON.
WINDS HAVE INCREASED ACROSS THE FAR OFFSHORE WATERS AND HAVE
UPDATED MARINE FORECAST TO WORD SCEC FOR THE 20-60NM THIS
AFTERNOON. OTHERWISE...LIGHT TO MODERATE SOUTH WINDS WILL PREVAIL
ACROSS THE COASTAL WATERS TONIGHT BEFORE A COLD FRONT MOVES
OFFSHORE THE LOWER TEXAS COAST FRIDAY. WINDS WILL SHIFT TO THE
NORTHWEST AND INCREASE FRI AFTERNOON INTO FRI NIGHT. SMALL CRAFT
ADVISORIES WILL BE NEEDED LATE FRI AFTERNOON THROUGH FRI NIGHT FOR
ALL OF THE COASTAL WATERS.

UNSETTLED WEATHER TO CONTINUE SATURDAY WITH NORTH WINDS STILL
STRONG AND SEA HIGH ENOUGH TO WARRANT SCA CONDITIONS TO CONTINUE.
BRIEF IMPROVING CONDITIONS ON SUNDAY AS WINDS VEER SOUTHEAST.
DEVELOPING STORM SYSTEM OVER THE DESERT SOUTHWEST INCREASES THE
WINDS SUNDAY NIGHT AND MONDAY BEFORE A COLD FRONT MOVES THROUGH
TUESDAY. A LONG PERIOD OF NORTH WINDS AND VERY UNSETTLED WEATHER
THEN CONTINUES THROUGH THURSDAY AS THE MAIN STORM SYSTEM OUT WEST
WILL BE SLOW IN MOVING EAST. SMALL CRAFT CONDITIONS ARE LIKELY
FROM MONDAY THROUGH THURSDAY.
