AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BROWNSVILLE TX
327 AM CST MON MAR 7 2011

.SHORT TERM /TODAY THROUGH 6 PM TUESDAY/SFC RIDGE SHIFTING TO THE
EAST TODAY WILL BATTLE WITH LOW PRESSURE BUILDING IN THE
PANHANDLE. THIS WILL BRING BREEZY SOUTHEAST WINDS TO THE REGION
TODAY...WITH STRONGEST WINDS RIGHT AT THE COAST IN CAMERON COUNTY.
SOUTHEAST WINDS WILL ALSO QUICKLY INCREASE LLVL MOISTURE FOR THE
REGION...TRAPPED UNDER STRONG CAPPING INVERSION. CLOUD COVER WILL
INCREASE THROUGH THE DAY...WITH GRADUALLY INCREASING CLOUDINESS
TODAY AND TONIGHT. BREEZY CONDITIONS REMAIN THROUGH THE NIGHT
TONIGHT...BECOMING AN INHIBITING FACTOR FOR FOG FORMATION...BUT
CONDITIONS WILL STILL BE HAZY AT TIMES TONIGHT. WINDS WILL BE
SOMEWHAT LIGHTER TUESDAY AS THE LOW PRESSURE AREA MOVES INTO NORTH
TEXAS...DECREASING THE PRESSURE GRADIENT. JET DYNAMICS ALOFT WILL
PROVIDE SOME LIFTING...BUT WILL HAVE TROUBLE BREAKING THROUGH
DOMINANT CAPPING INVERSION...BRINGING ONLY VERY SLIGHT CHANCE /10
POPS/ AT BEST. DRYLINE ATTEMPTS TO INTRUDE INTO THE FAR WESTERN
COUNTIES TOMORROW...LOWERING RH VALUES AND ALLOWING TEMPS TO
INCREASE INTO THE LOWER 90S FROM RIO GRANDE CITY TO HBV AND POINTS
WEST. WHILE LOW RH VALUES WILL ARRIVE OUT WEST...WINDS IN THE
WESTERN COUNTIES WILL FALL BELOW 10 KNOTS...WITH SOME NEARLY CALM
CONDITIONS EXPECTED.

&&

.LONG TERM /6PM TUESDAY THROUGH SUNDAY...QUICK MID TO UPPER LEVEL
FLOW OVER THE CONUS WITH A FEW SHORTWAVE TROUGHS AND COLD FRONTS
TO AFFECT DEEP SOUTH TEXAS IN THE LONG TERM. JET STREAM AND MOST
ENERGY REMAINS WELL NORTH OF THE REGION LIMITING RAIN CHANCES BUT
WILL ALLOW FOR INCREASED WINDS AND HUMIDITY IN ADVANCE OF THE
FRONTS WITH DRIER TO FILTER IN IN WAKE OF THE FRONTS. SHALLOW MOISTURE
TO POOL IN ADVANCE OF THE FIRST FRONT TUESDAY NIGHT WITH FOG AND
LOW CLOUDS DEVELOPING. THUNDER DROPPED FROM THE FORECAST AS THE
FRONT WORKS ITS WAY THROUGH THE CWA TUESDAY NIGHT INTO EARLY
WEDNESDAY. LIMITED INSTABILITY AND UPWARD VERTICAL MOTION TO KEEP
PRECIPITATION IN THE FORM OF SHOWERS. GRADUALLY DRYING TAKES PLACE
WEDNESDAY AND THURSDAY WITH SLIGHTLY COOLER TEMPERATURES.
NAM...GFS AND ECMWF ARE CONSISTENT WITH THIS TREND AND GUIDANCE
REMAINS WITHIN REASON FOR A HIGH CONFIDENCE FORECAST. NEXT MAIN
SHORTWAVE PASSES WELL NORTH WITH A WEAK SOUTHERN JET SHORTWAVE TO
ENHANCE THE RETURN FLOW FRIDAY AND OVER THE WEEKEND. MOISTURE
DEEPENS BUT UNCERTAINTY RESIDES ON THE STRENGTH OF THE SOUTHERN
SHORTWAVE. CLOUDS...WINDS AND TEMPERATURES TO INCREASE FRIDAY AND
SATURDAY. LOW CHANCE OF SHOWERS SUNDAY AS THE SHORTWAVE TRAVERSES
THE REGION WITH MOST AREAS SEEING MOSTLY CLOUDY CONDITIONS AND
MILD TEMPERATURES.

&&

.AVIATION...VFR CONDITIONS HAVE CONTINUED FURTHER INTO THE NIGHT AS
OFFSHORE CLOUD COVER HAS NOT BEGUN TREK INLAND YET. THIS IS EXPECTED
TODAY AS BREEZY SOUTHEAST WINDS PUSH GULF MOISTURE INTO THE REGION
AND TRAP IT UNDER STRONG INVERSION AROUND 3KFT. WILL MAKE
ADJUSTMENTS TO CLOUD COVER FOR MORNING HOURS...BUT CONTINUE TO
EXPECT SCT TO BKN CIGS RIGHT AROUND 3KFT THROUGH THE
AFTERNOON...ESPECIALLY NEAR THE COAST. SFC WINDS TODAY WILL BE 15 TO
20 KNOTS...WITH A FEW GUSTS REACH 30KTS FOR KBRO AND KHRL THIS
AFTERNOON. WINDS DECREASE OVERNIGHT...BUT WILL NOT GO CALM. THIS
WILL INHIBIT FOG FORMATION...BUT NOT COMPLETELY STOP IT.

&&

.MARINE...TODAY THROUGH 6 PM TUESDAY...BREEZY SOUTHEAST WINDS BEGIN
TO RAMP UP TODAY BETWEEN DEPARTING HIGH PRESSURE RIDGE TO THE EAST
AND DEEPENING LOW PRESSURE IN THE PANHANDLE. WINDS MAY REACH NEAR
ADVISORY STATUS FOR THE LAGUNA MADRE TODAY...BUT THE BRIEFNESS OF
THE EVENT WILL NOT WARRANT AN ADVISORY AT THIS MOMENT...BUT WILL BE
MONITORED FOR CHANGES. MARINE MIXING OVERNIGHT WILL SHIFT STRONGEST
WINDS OFFSHORE...WITH WINDS AGAIN APPROACHING 20 KNOTS FOR THE GULF
ZONES. SEAS WILL GRADUALLY INCREASE TO 5 TO 6 FEET FOR THE GULF
OVERNIGHT. AREA WILL BE MONITORED ALSO FOR POSSIBLE ADVISORIES
TONIGHT. THE LOW PRESSURE IN THE PANHANDLE SHIFTS TO NORTH TEXAS
TUESDAY...WITH SOME RELAXING OF THE GRADIENT. WINDS ARE FORECAST AT
15 TO 20 KNOTS AT THE PEAK.

TUESDAY NIGHT THROUGH FRIDAY...A COLD FRONT IS EXPECTED TO ENTER
THE COASTAL WATERS EARLY WEDNESDAY. SOUTHEAST WINDS IN ADVANCE OF
THE FRONT WEAKEN BEFORE INCREASING FROM THE NORTH WITH SMALL CRAFT
ADVISORIES LIKELY WEDNESDAY FOR ALL COASTAL WATERS. WINDS TO
SLOWLY DIMINISH WITH THE OUTER WATERS SEEING WINDS DROP BELOW SCA
