AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BROWNSVILLE TX
1146 PM CST TUE DEC 4 2012

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

&&

.AVIATION...STRONG CONVECTION PUSHING SOUTH INTO WILLACY COUNTY
THIS HOUR...EXPECT IT TO CONTINUE AT ABOUT THE CURRENT
VELOCITY...OR SLIGHTLY SLOWER AS IT TRACKS SOUTHEAST. COULD BE
INTO THE LOWER VALLEY BY AROUND 100 AM...TRACKING THROUGH BY ABOUT
330 TO 400 AM. STRONG WINDS AND HAIL MAY REMAIN POSSIBLE AS IT
MOVES SOUTH...ALTHOUGH SOME WEAKENING IS POSSIBLE. IFR VISBY IN
THE CORE OF THE STORM WITH BRIEF MVFR CIGS RIGHT ALONG THE FRONT.
DO EXPECT A QUICK RECOVERY THOUGH TO VFR THROUGH THE NIGHT AND THE
PROSPECTS OF SIGNIFICANT FOG ARE LOWERING AS THE FRONT PUSHES
A COUPLE OF HOURS AHEAD OF SCHEDULE. WIND SHIFT TO THE NORTH
AROUND DAYBREAK...BECOMING GUSTY BY MID MORNING AT 15 TO 20
KNOTS...DIMINISHING AROUND SUNSET. /68-JGG/

&&

.PREV DISCUSSION... /ISSUED 1114 PM CST TUE DEC 4 2012/

DISCUSSION...UPPER AIR AND SPC MESOANALYSIS COUPLED WITH LOCAL
LAPS DATA SHOWS ABOUT 40 TO 50 KNOTS OF 0-6KM SHEAR BEHIND A
DEVELOPING LINE OF STRONG TO SEVERE THUNDERSTORMS OVER SOUTHERN
KENEDY COUNTY STRETCHING TO OUR EASTERN COASTAL WATERS. STRONG
LARGE SCALE ASCENT PROVIDED BY THE LEFT EXIT REGION OF A DIVING IS
CONTINUING TO PROVIDE GOOD SFC CONVERGENCE FOR THUNDERSTORM
INITIATION AMID ABOUT 1200 TO 1500 J/KG OF SURFACE BASED CAPE OVER
LAND AND ABOUT 2200 J/KG OVER THE WARMER AND MORE MOIST GULF
WATERS WHERE THE CONVECTION APPEARS THE STRONGEST OVERALL WITH
NUMEROUS 50DBZ RETURNS OVER 35KFT ON KBRO AND CRP RADARS...WITH
THE STRONGEST STORM OVER LAND NEAR RUDOLPH.

EXPECT THE NEAR SFC BOUNDARY LAYER TO COOL OVERLAND SLOWLY AND
POSSIBLY LIMIT UPDRAFT POTENTIAL...BUT WITH AVAILABLE SHEAR STILL
BELIEVE IT POSSIBLE TO SEE SOME STRONG TO BORDERLINE SEVERE STORMS
WITH LARGE HAIL THE MAIN THREAT...AS STORMS POSSIBLY BECOME
SLIGHTLY ELEVATED...STILL CAN NOT RULE OUT AN ISOLATED
GUSTY/DAMAGING WIND THREAT WITH STRONGER STORMS. STORMS ARE MOVING
QUICKLY ENOUGH TO PREVENT SIGNIFICANT FLOODING CONCERN. EXPECT
FRONTAL BOUNDARY TO CONTINUE TO PUSH SOUTHWARD AND APPROACH THE
LOWER VALLEY BETWEEN 3 AND 6 AM THIS MORNING...WITH MOST
CONVECTION STUCK RIGHT TO THE BOUNDARY DUE TO A NEUTRALLY TO
NEGATIVELY BUOYANT LOWEST FEW THOUSAND FEET OF THE COLUMN.

BUMPED UP RAIN CHANCES FROM MIDNIGHT TO 6 AM FROM ABOUT WESLACO
EAST TO RAYMONDVILLE AND PORT MANSFIELD AND ESPECIALLY OVER THE
COASTAL WATERS WHERE PRECIP APPEARS TO BE A NO BRAINER THROUGH 6
AM. STRONG TO SEVERE STORMS WILL BE POSSIBLE...BUT ARE NOT A SURE
THING...OVER LAND ALONG THE FRONT...AND ARE A NEAR CERTAINTY OVER
THE GULF WATERS WHERE SPECIAL MARINE WARNINGS HAVE ALREADY BEEN
ISSUED. /68-JGG/

PREV DISCUSSION... /ISSUED 647 PM CST TUE DEC 4 2012/

DISCUSSION...UPDATED FOR LATEST AVIATION DISCUSSION BELOW.

AVIATION...THE AFTERNOON SEA BREEZE HAS PUSHED INLAND AND IS NOW
MEETING UP WITH THE COLD FRONT PUSHING SOUTHEAST TOWARDS DEEP
SOUTH TX. SO FAR THIS BOUNDARY COLLISION HAS FAILED TO PRODUCE ANY
SIGNIFICANT CONV OVER THE BRO CWA WITH ALL OF THE STRONGER CONV
CONFINED TO THE MIDDLE AND UPPER TX COASTLINES. RIGHT NOW WITH THE
LOSS OF THE AFTERNOON HEATING AND THE LOWERING OF THE LOW LEVEL
TEMPS THE ATMS IS STARTING TO STABILIZE SOMEWHAT AS THE EVENING
PROGRESSES. DESPITE THE MORE STABLE ATMS THE LAST SWOMCD FROM SPC
INDICATED THAT A MID LEVEL SPEED MAX IS APPROACHING THE REGION
FROM THE WEST. THIS FEATURE IN ADDITION TO THE APPROACHING SURFACE
BOUNDARY WILL MAINTAIN ENOUGH UVV FOR GENERAL CONV. HOWEVER
BELIEVE THAT THE POTENTIAL FOR SVR CONV MAY BE FADING A BIT. SOME
HIGHER CAPE VALUES LINGER JUST ALONG THE COASTLINE AND FURTHER
OFFSHORE SO THE BEST POTENTIAL FOR STG/SVR CONV WILL PERSIST HERE
FOR THE NEXT SEVERAL HOURS. WILL HOLD OFF ON INCLUDING A MENTION
OF CONV FOR THE LOWER RGV AIRPORTS AS WOULD LIKE TO SEE BETTER
DEVELOPMENT ON THE SOUTH END OF THE FRONT.

BIG DIFFERENCES SHOW UP BETWEEN THE GFS AND NAM CEILINGS AND
VSBYS. THE GFS IS GOING WITH A DRY FROPA WITH NO SERIOUS CEILINGS
OR REDUCTIONS TO VSBYS WHILE THE NAM TAKES THE CEILINGS AND VSBYS
DOWN TO LIFR LEVELS. FOR NOW WILL GO CLOSER TO THE GFS/GFS LAMP
TRENDS WHICH SEEM TO BE MATCHING UP BETTER WITH THE REAL TIME
CONDITIONS. BELIEVE THAT SOME FOG MAY FORM AS THE SURFACE WINDS
SLACKEN AHEAD OF THE FRONT...BUT NOT TO THE DEGREE INDICATED BY
THE NAM GUIDANCE. THIS MAY RESULT IN SOME MVFR/BRIEF IFR
CONDITIONS AHEAD OF FRONT. OTHERWISE EXPECT VFR CONDITIONS IN THE
WAKE OF THE FROPA LATER TONIGHT THROUGH TOMORROW EVENING.

PREV DISCUSSION... /ISSUED 235 PM CST TUE DEC 4 2012/

SHORT TERM /NOW THROUGH WEDNESDAY NIGHT/...CURRENT SURFACE
OBSERVATIONS AND SATELLITE IMAGES DEPICTS THE WEAK SURFACE COLD
FRONT FROM EAGLE PASS TO BASTROP TEXAS. THE FRONT IS EXPECTED TO
CONTINUE TO MOVE SOUTHEASTWARD THROUGH TONIGHT. CURRENT WSR-88D
SHOWS CONVECTION DEVELOPING OVER THE LOWER TEXAS COASTAL WATERS
EARLY IS AFTERNOON. VISIBLE SATELLITE IMAGES SHOWS AN INCREASING CU
FIELD ACROSS DEEP SOUTH TEXAS EARLY THIS AFTERNOON. SURFACE
TEMPERATURES ARE IN THE LOW TO MID 80S WITH DEWPOINTS IN THE MIDDLE
60S ACROSS THE AREA ALONG WITH AN UNSTABLE AIRMASS OVER THE
NORTHEASTERN PORTION OF THE CWA. AN UPPER JET IS MOVING ACROSS SOUTH
TEXAS THIS AFTERNOON. THERE IS AN ISOLATED RISK OF A SEVERE STORMS
THIS AFTERNOON AS THIS UPPER FEATURE MOVES ACROSS THE DESTABILIZING
AIRMASS. THE GREATEST RISK AREA FOR SEEING ISOLATED SEVERE STORMS
WILL BE IN AREAS NORTH AND EAST OF A LINE FROM FALFURRIAS...TO
RAYMONDVILLE...TO PORT MANSFIELD. THE PRIMARY IMPACTS WOULD BE WIND
GUSTS OF 60 TO 70 MPH...AND QUARTER SIZE HAIL. BRIEF PERIODS OF
HEAVY RAIN WILL ALSO BE POSSIBLE. OTHERWISE...SHOWERS AND
THUNDERSTORMS WILL DEVELOP AHEAD AND ALONG THE FRONT. THE FRONTAL
BOUNDARY IS EXPECTED TO REACH THE UPPER VALLEY AROUND 10 PM TONIGHT
AND THE LOWER VALLY AROUND MIDNIGHT. WINDS WILL SHIFT TO NORTH TO
NORTHWEST BEHIND THE FRONT.

A SECONDARY SURGE OF THE BOUNDARY THROUGH THE AREA IS EXPECTED ON
WEDNESDAY AS SURFACE RIDGING TAKES BUILDS BEHIND THE FRONT. HIGH
TEMPERATURES ON WEDNESDAY WILL BE ABOUT 8 TO 10 DEGREES COOLER
THAN TODAY WITH HIGHS IN THE LOW TO MID 70S AREA WIDE. LOWS
TONIGHT WILL BE IN THE UPPER 50S OVER THE NORTH AND LOWER 60S IN
THE VALLEY. OVERNIGHT LOWS WEDNESDAY NIGHT WILL BE IN THE MID TO
UPPER 50S WITH LOWER 60S NEAR THE COAST.

LONG TERM/THURSDAY THROUGH TUESDAY/...A RATHER ZONAL FLOW ALOFT
WILL CONTINUE THROUGH THE REMAINDER OF THE WEEK WITH A SHORTWAVE
EMBEDDED WITHIN THE FLOW MOVING EASTWARD. THIS DISTURBANCE WILL
REMAIN FURTHER NORTH OF THE CWA AND WILL NOT BE AN IMPACT TO THE
RGV. HIGH TEMPERATURES WILL GRADUALLY WARM INTO THE UPPER 70S FOR
THURSDAY WITH SE WINDS RETURNING QUICKLY. CONDITIONS WILL BE DRY
THROUGH THE END OF THE WEEK. SE FLOW BEGINS TO INCREASE INTO
FRIDAY AS ANOTHER STRONG DEEPER TROUGH DEVELOPS OVER THE PACIFIC
NORTHWEST AND AN ASSOCIATED LEE SIDE TROUGH STRENGTHENS. BREEZE TO
WINDY CONDITIONS WILL BE EXPECTED FOR FRIDAY INTO SATURDAY AS THE
GRADIENT IN THE LOWER VALLEY STRENGTHENS ESPECIALLY ALONG THE
COASTAL COUNTIES. HIGH TEMPERATURES INTO THE WEEKEND WILL BE A FEW
DEGREES ABOVE NORMAL.

THE STRONGER SYSTEM ACCORDING TO THE GFS AS WELL AS THE ECMWF ARE
HINTING THE UPPER LEVEL LOW WILL DIG SOUTHWARD INTO THE DESERT SW
AND NORTHERN MEXICO. EITHER SOLUTION PLANS OUT...A STRONG COLD FRONT
ASSOCIATED WITH THIS SYSTEM WILL MAKE ITS WAY SOUTH INTO THE VALLEY.
BOTH MODELS HAVE A LITTLE BIT OF DISAGREEMENT ON THE TIMING OF THIS
FRONT BUT IT WILL LIKELY BE ARRIVING INTO THE LOWER VALLEY BY 06Z TO
12Z TUESDAY. EXPECT SHOWER ACTIVITY TO ENHANCE AHEAD OF THE FRONT
ACROSS THE CWA WITH BREEZE TO WINDY CONDITIONS RIGHT BEHIND THIS
SYSTEM. GFS IS A LITTLE MORE AGGRESSIVE WITH POPS WHILE THE ECMWF IS
KEEPING MOST OF THE ACTIVITY OVER THE GULF WATERS. AT THIS TIME LEFT
20 PERCENT POPS AS IT IS STILL AT THE END OF THE LONG TERM PERIOD.
TEMPERATURES EARLY IN THE WEEK WILL BE UNIFORMLY ABOVE NORMAL ACROSS
THE CWA REACHING THE MID TO LOWER 80S WITH LOW TEMPERATURES IN THE
MID 60S. AFTER THIS FRONT MOVES THROUGH TUESDAY...HIGH TEMPERATURES
WILL STILL REACH THE MID TO LOW 70S FURTHER SOUTH INTO THE LOWER
VALLEY.

MARINE...NOW THROUGH WEDNESDAY NIGHT...BUOY 020 REPORTED EAST
SOUTHEAST WINDS AROUND 8 KNOTS WITH SEAS OF 4 FEET EARLY THIS
AFTERNOON. LIGHT EAST TO SOUTHEAST WINDS WILL CONTINUE THIS
AFTERNOON WITH WINDS BECOMING EAST THIS EVENING AS THE WEAK COLD
FRONT APPROACHES THE LOWER TEXAS COAST. THE FRONTAL BOUNDARY WILL
PUSH THROUGH LATER TONIGHT INTO WEDNESDAY MORNING...WITH ISOLATED
TO SCATTERED SHOWERS AND STORMS. MODERATE NORTH TO NORTHEAST WINDS
WILL DEVELOP WEDNESDAY AFTERNOON. EXERCISE CAUTION CONDITIONS
POSSIBLE ON ALL WATERS WEDNESDAY AFTERNOON...BUT CURRENTLY
ADVISORY LEVEL WINDS DO NOT APPEAR LIKELY...WITH SEAS REMAINING
MODERATE.

SATURDAY NIGHT THROUGH FRIDAY...SOUTHEAST WINDS WILL GRADUALLY
INCREASE INTO FRIDAY AS GRADIENT STRENGTHENS OVER THE LOWER
VALLEY. THIS IS DUE TO A STRONGER UPPER LEVEL SYSTEM ENTERING THE
PACIFIC NORTHWEST. THIS SYSTEM WILL DIG SOUTHWARD INTO THE DESERT
SOUTHWEST AND BRING A FRONT ACROSS VALLEY BY TUESDAY. STRONGER
NORTH TO NORTHWEST FLOW WILL INCREASE BEHIND THIS FRONT ACROSS THE
VALLEY AND WILL BUILD SEAS. EXPECT CLOSE TO SCA INTO THE WEEKEND
WITH THE SE FLOW ACROSS THE GULF WATERS LATE FRIDAY INTO SATURDAY
AND POSSIBLY CONTINUING INTO SUNDAY. ON TUESDAY AS THE FRONT MOVES
THROUGH THE GULF...EXPECT A NORTHERLY PUSH WITH THE FRONT WITH
SEAS BETWEEN 3 TO 5 FEET AND POSSIBLY INCREASE TO 6 FEET.
