...RED FLAG WARNING REMAINS IN EFFECT UNTIL 3 PM CST THIS
AFTERNOON...

A RED FLAG WARNING REMAINS IN EFFECT UNTIL 3 PM CST THIS
AFTERNOON. 

FREEZING TEMPERATURES THAT AFFECTED MUCH OF DEEP SOUTH TEXAS LATE
LAST WEEK HAS LIKELY RESULTED IN A GREATER ABUNDANCE OF DRY OR
CURED FUELS. VERY DRY AIR WILL POUR ACROSS OUR AREA TODAY DUE TO 
BREEZY NORTHERLY WINDS OCCURRING IN THE WAKE OF THE PASSAGE OF A
COLD FRONT EARLY THIS MORNING. THE COMBINATION OF THE FUELS...
STRONGER NORTHERLY WINDS AND MUCH DRIER AIR WILL LEAD TO A
GREATER RISK OF WILDFIRES THAT WILL BE DIFFICULT TO CONTROL IF IT
INITIATES TODAY. THEREFORE...A RED FLAG WARNING IS IN EFFECT FOR 
ALL OF DEEP SOUTH TEXAS THROUGH THE EARLY AFTERNOON HOURS.

THE WILDFIRE RISK WILL DECREASE LATE THIS AFTERNOON...AND EVEN
MORE SO TONIGHT...AS WINDS DIMINISH AND RELATIVE HUMIDITY VALUES
INCREASE.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A RED FLAG WARNING MEANS CRITICAL FIRE WEATHER CONDITIONS ARE
OCCURRING NOW...OR WILL SHORTLY. THESE CONDITIONS INCLUDE
SUSTAINED 20 FOOT WINDS OF 25 MPH OR GREATER AND CURED FUELS...OR
THE COMBINATION OF RELATIVE HUMIDITY BELOW 35 PERCENT FOR 2 HOURS
OR MORE AND SUSTAINED 20 FOOT WINDS OF 25 MPH OR HIGHER WHEN
FUELS ARE NOT CURED. THESE CONDITIONS WILL CREATE EXPLOSIVE FIRE
GROWTH POTENTIAL.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BROWNSVILLE TX
937 PM CST MON NOV 29 2010

.SHORT TERM /TONIGHT THROUGH 6 AM WEDNESDAY/...OVERALL...FORECAST
LOOKS GOOD WITH ONLY MINIMAL CHANGES. ADDED PATCHY FOG TO THE
MIDDLE AND LOWER VALLEY AND COASTAL REGIONS FOR THE OVERNIGHT PERIOD
UNTIL THE ARRIVAL OF THE COLD FRONT BETWEEN 3 AND 6 AM. AS WINDS
CONTINUE TO DECOUPLE AND DEW POINTS RECOVER PATCHY FOG IS
ANTICIPATED. VISIBILITIES OF 2 TO 4 MILES WITH PATCHES LESS THAN ONE
MILE POSSIBLE NEAR THE COAST AND IN THE LOWER VALLEY. ALSO TWEAKED
THE CLOUD COVER ACROSS THE EAST AS LOW CLOUDS ARE SLOWLY INCREASING
SOUTH TO NORTH.

CURRENTLY THE MAIN COLD FRONT IS LOCATED OVER NORTH CENTRAL TO WEST
CENTRAL TEXAS AND MOVING STEADILY SOUTHEAST. ALL SHORT RANGE MODELS
INDICATE THE FRONT TO ACCELERATE OVERNIGHT MOVING OFFSHORE THE LOWER
COAST AROUND SUNRISE. SHARP TROUGH WITH A 50 KNOT+ LOW LEVEL JET
STREAK AT 92H TO HELP SURGE THE SOUTH THROUGH THE REGION. AS THE
SUNRISES SOME OF THIS JET SHOULD MIX TO THE SURFACE PRODUCING A
SHORT WINDOW OF GUSTY WINDS. A WIND ADVISORY MAY BE NEEDED TO
ACCOMMODATE THESE STRONGER WINDS WHICH COULD GUSTS OVER 40 MPH OVER
THE EASTERN THIRD OF DEEP SOUTH TEXAS.  NOT EXPECTING MUCH IN THE
WAY RAIN BUT THE STRONG JET AND SHARP TROUGH COULD SQUEEZE OUT A FEW
SHOWERS. THEY SHOULD QUICKLY MOVE EAST WITH THE FRONT.
&&

.LONG TERM /WEDNESDAY THROUGH MONDAY/...A RECOVERY AND MODERATING
PERIOD WILL TAKE PLACE DURING THE LONG TERM FCST PERIOD. AFTER A
COLD START TO WEDNESDAY WITH POSSIBLE FREEZING TEMPERATURES...A
DECENT RECOVERY WILL BEGIN TO TAKE PLACE WITH A FAIR AMT OF SUNSHINE
HELPING TO BOOST AFTN READINGS INTO THE 70S. WILL CONTINUE THE
WARMING TREND THEREAFTER AS SFC HIGH PRESSURE SLIDES EWD AND WE
GET A RETURN FLOW OFF THE GULF OF MEXICO. THIS WILL MODIFY OVRNGT
LOWS WITH TIME AND ALSO HELP DAYTIME HIGHS TO WARM. NEAR NORMAL TO
ABOVE NORMAL TEMPERATURES ARE EXPECTED TO PREVAIL THRU THE
MAJORITY OF THE PERIOD. ONE ITEM TWD THE END OF THE PERIOD WE WILL
HAVE TO CONTINUE TO WATCH IS FOR ANOTHER POTENTIAL COLD FRONTAL
PASSAGE EARLY NEXT WEEK...SO STAY TUNED. NO CHANGES MADE TO THE
LONG TERM FCST AT THIS TIME.
&&

.MARINE...
TONIGHT THROUGH 6 AM WEDNESDAY...SMALL CRAFT ADVISORIES AND GALE
WARNING WILL REMAIN IN EFFECT THROUGH THE NIGHT AND TUESDAY. COLD
FRONT TO MOVE THROUGH THE NORTHERN WATERS AFTER 3 AM AND SOUTH OF
THE MOUTH OF THE RIVER AROUND 6 AM. EXPECT GALE FORCE WINDS TO MIX
TO THE SURFACE AN HOUR OR TWO AFTER THE FRONT. STRONG WINDS TO
LAST INTO THE LATE AFTERNOON FOR THE OUTER WATERS. MARINE
CONDITIONS TO BEGIN IMPROVING TUESDAY NIGHT WITH ALL ADVISORIES
LIKELY TO BE LIFTED WEDNESDAY MORNING.

WEDNESDAY THROUGH SATURDAY...A RETURN TO ONSHORE FLOW WILL TAKE
PLACE ON WEDNESDAY AND PREVAIL THRU THE END OF THE FORECAST PERIOD
ACROSS THE LWR TX MARINE AREAS. THE FLOW IS ANTICIPATED TO REMAIN
LIGHT TO MODERATE THRU THE END OF THE WEEK WHICH IN TURN WILL MEAN
LIGHT TO MODERATE SOUTHEAST WINDS AND LOW TO MODERATE SEAS. NO
CHANGES MADE TO THE ONGOING MARINE FORECAST AT THIS TIME.
&&

.AVIATION...
WINDS HAVE DIMINISHED THIS EVENING...BEFORE INCREASING FROM THE
NORTH BEHIND A COLD FRONT AROUND 3 AM ACROSS THE NORTHERN COUNTIES
AND BETWEEN 5 AND 6 AM FOR THE REGIONAL AIRPORTS. STRONG JET OF
50+ KNOTS AT AROUND 3000 FEET IS FORECAST TO ACCOMPANY THE FRONT.
SURFACE WINDS TO INCREASE WITH THE FRONTAL PASSAGE BUT STRENGTHEN
AFTER SUNRISE WITH A PORTION OF THE JET TO MIX TO THE SURFACE.
WIND GUSTS TO AT LEAST 35 KNOTS ARE EXPECTED IN THE MORNING WITH
GUSTS BECOMING WEAKER AND LESS FREQUENT IN THE AFTERNOON AS THE
JET SHIFTS EAST. PATCHY LOW CLOUDS AND SOME FOG MAY PRECEDE THE
FRONT ACROSS THE REGIONAL AIRPORTS AND MAY APPROACH IFR LEVELS BUT
EXPECT MOSTLY MVFR CIGS AND VSBYS. VFR CONDITIONS TO PREVAIL MUCH
OF TUESDAY ACROSS ALL AREAS.
&&

.FIRE WEATHER...
STRONG NORTHERLY WINDS...LOW RELATIVE HUMIDITIES...AND CURED
FUELS WILL ELEVATE THE FIRE WEATHER CONCERNS TUESDAY MORNING.
DECIDED TO LEAVE INHERITED FIRE WEATHER WATCH IN PLACE AND LET
LATER SHIFTS DECIDE WHETHER TO UPGRADE TO A RED FLAG WARNING OR
NOT. 20 FOOT WIND CRITERIA LOOKS TO BE BORDERLINE AT THIS
TIME...BUT DONT WANT TO UNDERPLAY THE FIRE WEATHER POTENTIAL.
WINDS SUBSIDE AND RH VALUES REBOUND TUESDAY EVENING DRASTICALLY
REDUCING THE FIRE WEATHER CONCERNS.

.PREV DISCUSSION.../ISSUED 212 PM CST MON NOV 29 2010/

SHORT TERM /TONIGHT THROUGH 6 AM WEDNESDAY/...PRE FRONTAL TROUGH
HAS BROUGHT LIGHT NORTH AND NORTHWEST WINDS TO THE CENTRAL AND
WESTERN AREAS OF DEEP SOUTH TEXAS. BREEZY SOUTHERLY WINDS CONTINUE
ACROSS THE EASTERN COUNTIES AND THE ADJACENT COASTAL WATERS. THE
COLD FRONT IS STILL ON TRACK TO MOVE THROUGH DEEP SOUTH TEXAS AROUND
MIDNIGHT TONIGHT. STRONG WINDS ARE ANTICIPATED BEHIND THE
FRONT...ESPECIALLY ALONG THE COAST WHERE GALE WARNING HAVE BEEN
HOISTED FOR TUE. THE SLIGHT CHANCE OF SHOWERS WITH FROPA WAS
RETAINED...BUT ANY RAIN SHOULD BE LIGHT. DRIER AIR ADVECTING INTO
THE AREA BEHIND THE FRONT ALONG WITH THE STRONG NORTHERLY WINDS WILL
ENHANCE THE FIRE DANGER THREAT. WINDS ARE EXPECTED TO SUBSIDE BUT A
COLD NIGHT IN STORE TUESDAY NIGHT.

LONG TERM...6 AM WEDNESDAY THROUGH MONDAY...AFTER TEMPS DROP DOWN
TO BELOW CLIMO IN THE WAKE OF THE FROPA EARLY TUES AND WED THE
MERCURY WILL THEN START TO WARM AS THE MID LEVEL RIDGING BUILDS
BACK IN PLACE OVER THE SOUTH CENTRAL PLAINS STATES. GOOD
RADIATIONAL EFFECTS WILL SET THE STAGE FOR A POSSIBLE FREEZE EVENT
ACROSS THE NORTHERN TIER OF COUNTIES EARLY WED MORNING. HAVE
POSTED A FREEZE WATCH FOR THESE FOUR COUNTIES. THE MID LEVEL
RIDGING WILL MAINTAIN GENERALLY NIL POPS INTO NEXT WEEKEND WITH
STEADILY WARMING THROUGH THE PERIOD AS 1000-500 MB THICKNESSES
INCREASE AND THE WAA RETURNS. GFS MEX MOS AND ENSEMBLE TEMP AND
POP GUIDANCE SHOWS GOOD AGREEMENT THROUGH DAY 7 AND WILL GO WITH
THE ENSEMBLE NUMBERS FOR THE 3 TO 7 DAY RANGE. BOTH THE ECMWF AND
GFS GUIDANCE INDICATE THE POTENTIAL FOR ANOTHER FAIRLY STRONG
FROPA EARLY NEXT WEEK AND ALSO SOME POTENTIAL FOR A COASTAL
TROFFING EVENT JUST OFFSHORE OF THE REGION POSSIBLY INCREASING
POPS. ONCE AGAIN WILL SEE HOW FUTURE MODEL RUNS TRY TO RESOLVE
THIS FEATURE.
