AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE BROWNSVILLE TX
134 PM CST FRI NOV 20 2015

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

&&

.AVIATION...THE MAIN BODY OF PCPN HAS SHIFTED NORTH OVER
WILLACY AND KENEDY COUNTIES AND OUT OVER THE BAY AND GULF WATERS
AND CONTINUE TO MOVE NORTH. MORE PATCHY RAIN IS MOVING UP FROM THE
SOUTH ALSO. THE CEILINGS AND VSBYS WILL LIKELY RANGE BETWEEN
VFR/MVFR CRITERIA WITH SOME POSSIBLE BRIEF REDUCTIONS TO IFR
LEVELS AS HEAVIER SHOWERS MOVE OVER THE RGV AIRPORTS. EXPECT THE
PCPN THREAT TO SHIFT A LITTLE MORE OFFSHORE LATER THIS EVENING
INTO THE OVERNIGHT HOURS. AT THIS POINT HOWEVER THE PROBLEM WILL
LIKELY BE AREAS OF FOG AND LOW CLOUDS FORMING UP AHEAD OF THE
FRONT PUSHING SOUTH INTO DEEP SOUTH TX. THIS WILL LIKELY RESULT IN
CEILINGS TRENDING MORE TOWARDS IFR LEVELS AS THE LOW CLOUDS AND
FOG FORM UP. THE AVIATION CONDITIONS WILL IMPROVE SOMEWHAT LATER
TOMORROW AS THE COLD FRONT CLEARS THROUGH THE REGION. HOWEVER
T-STORMS WILL BE POSSIBLE TOMORROW AFTERNOON FOR THE RGV AIRPORTS
AS THE COLD FRONT MOVES CLOSER TO THE REGION.

&&

.PREV DISCUSSION... /ISSUED 838 AM CST FRI NOV 20 2015/

DISCUSSION...HAVE UPDATED THE MORNING FORECAST TO INCREASE POPS A
BIT ACROSS THE LOWER RGV. KBRO RADAR SHOWS A PRETTY LARGE AREA OF
SHOWERS WITH ISOLATED THUNDERSTORMS MOVING NORTH ALONG THE
COASTLINE OF NORTHEAST MEXICO. BELIEVE THAT SOME OF THIS RAINFALL
MAY EDGE INTO THE RGV FROM THE SOUTH WITH THE HEAVIES RAINFALL
OCCURRING ALONG THE COASTAL COUNTIES AND OFFSHORE. HAVE ALSO
UPDATED THE MARINE FORECAST TO POST A GALE WATCH FOR THE LOWER TX
MARINE LOCATIONS AFTER THE FROPA TOMORROW.

PREV DISCUSSION... /ISSUED 545 AM CST FRI NOV 20 2015/

DISCUSSION...UPDATED FOR LATEST AVIATION DISCUSSION BELOW.

AVIATION...KBRO DOPPLER RADAR SHOWS AN AREA OF LIGHT
PRECIPITATION APPROACHING THE MAJOR AERODROMES FROM THE
SOUTH...AND THE TIMING OF THIS RAINFALL HAS BEEN BUILT
INTO THE CURRENT SUITE OF TAFS. DRIER CONDITIONS SHOULD
DEVELOP DURING THE LATE MORNING OR EARLY AFTERNOON...
UNLESS A SECOND BATCH OF RAINFALL FARTHER DOWN THE COAST
OF TAMAULIPAS HOLDS TOGETHER AND AFFECTS THE LOCAL AREA
DURING THE AFTERNOON HOURS. ALTHOUGH VFR IS EXPECTED
THROUGH A MAJORITY OF THE NEXT 24 HOURS...THE FORMATION
OF FOG DURING THE EARLY MORNING HOURS OF SATURDAY IN
ADVANCE OF A COLD FRONT MAY BRING DEGRADED AVIATION
CONDITIONS AT THAT TIME AND UNTIL SUNRISE SATURDAY
MORNING.

PREV DISCUSSION... /ISSUED 414 AM CST FRI NOV 20 2015/

SHORT TERM  /TODAY THROUGH SATURDAY/...ISOLATED SHOWERS ARE
FLIRTING WITH THE LOWER TEXAS COASTAL WATERS RIGHT NOW...WITH A
LARGER AREA OF MORE WIDESPREAD SHOWERS OVER NORTHERN TAMAULIPAS
STATE.

TODAY...THE AFOREMENTIONED PRECIPITATION MAY AFFECT THE SOUTHERN
HALF OF THE BRO CWFA COURTESY OF WEAK INVERTED SURFACE TROUGHINESS
ALONG THE LOWER TEXAS COAST. OBSERVED HIGH TEMPERATURES WERE IN THE
MID 80S AT THE THREE OFFICIAL SITES ON THURSDAY...AND NEARLY SIMILAR
NUMBERS SHOULD OCCUR AGAIN FOR TODAY...AND WHAT IS CURRENTLY IN THE
OFFICIAL FORECAST MAY BE A COUPLE OF DEGREES TOO LOW ACROSS DEEP
SOUTH TEXAS AND THE RIO GRANDE VALLEY IF LESSER CLOUDINESS OCCURS
THAN IS CURRENTLY FORECAST.

TONIGHT...INVERTED SURFACE TROUGH INTENSIFIES SLIGHTLY...RESULTING
IN A CONTINUED SLIGHT OPPORTUNITY FOR RAINFALL INLAND AND A CHANCE
OF PRECIPITATION FOR THE ADJACENT COASTAL WATERS. INHERITED LOW
TEMPERATURES LOOKED REASONABLE AND WERE RETAINED GIVEN WHAT IS
CURRENTLY BEING OBSERVED ACROSS THE BRO CWFA FOR THE EARLY MORNING
HOURS OF FRIDAY.

SATURDAY...MAIN EVENT ARRIVES: THE FIRST MAJOR COLD FRONT OF THE
FALL SEASON. STORM PREDICTION CENTER HAS DEEP SOUTH TEXAS AND THE
RIO GRANDE VALLEY IN A GENERAL RISK OF THUNDERSTORMS...AND THIS HAS
BEEN BUILT INTO THE FORECAST FOR SATURDAY. SOMETHING TO MONITOR WILL
BE THE POTENTIAL FOR A WIND ADVISORY...WITH MEXHBV AND MEXHRL
SHOWING A BRIEF PERIOD OF 26-KNOT WINDS AND 30-KNOT WINDS...
RESPECTIVELY. GIVEN THE EARLY ARRIVAL OF THE COLD FRONT...CURRENT
HIGH TEMPERATURES INDICATED FOR THIS DAY MAY VERY WELL BE TOO WARM
ESPECIALLY WITH DENSE CLOUD COVER AND LIKELY PRECIPITATION
FORECAST.

LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...MAIN HIGHLIGHTS:
COLDER TEMPERATURES BEHIND THE FRONT EARLY SUNDAY MORNING WITH
A BRIEF PERIOD OF SHOWERS STILL LINGERING OVER THE LOWER VALLEY
SUNDAY.

UPPER TROUGH LIFTS NORTHEAST WITH RIDGE BUILDING ALONG THE WEST
COAST. SURFACE HIGH WILL CONTINUE TO BUILD INTO DEEP SOUTH TEXAS
SUNDAY INTO MONDAY BRINGING BELOW NORMAL TEMPERATURES EARLY SUN
MORNING. ABUNDANT DRY AIR BEHIND THE FRONT WILL ALLOW FOR SOME
CLEARING WITH MORE SUNSHINE REACHING THE SURFACE IN THE AFTERNOON
AS A RESULT WARMING TEMPERATURES BACK IN THE 60S OVER THE LOWER
RGV AND COOLER MID 50S OVER THE NORTHERN RANCHLANDS. RIDGE WEAKENS
INTO TUESDAY WITH A MORE ZONAL FLOW ALOFT ACROSS MUCH OF THE CONUS.
A WEAK 500MB SHORTWAVE TRAVELS EAST ACROSS MX INTO SOUTH TEXAS TUE
WHILE 850 MB SE FLOW FEEDS GULF MOISTURE AHEAD OF THIS WAVE WHICH
WILL INCREASE THE CHANCE OF RAIN TUESDAY AFTERNOON INTO WEDNESDAY.
WITH NO BIG CHANGES IN THE WEATHER PATTERN...THE MOISTURE CONTENT
REMAINS IN PLACE THROUGH WEDNESDAY WITH THE NEXT LOW PRESSURE SYSTEM
DIGGING SE OVER THE GREAT BASIN.

THE SOUTHEAST WINDS WILL PREVAIL AND STRENGTHEN THU THROUGH THE END
OF THE WEEK AS THE LOW PRESSURE MOVES INTO THE FOUR CORNERS REGION.
DEEPER MOISTURE WILL BE PULL NORTH ALONG THE CENTRAL PLAINS INCREASING
THE CHANCES OF RAIN SHOWERS THROUGH THE END OF THE WEEK. THE SE FLOW
WILL ALLOW FOR TEMPERATURES TO WARM BACK INTO THE 80S ACROSS THE AREA.
LOW TEMPERATURES WILL ALSO BE RISING TO THE MID 60S EARLY IN THE WEEK
AND IN THE 70S BY THE END OF THE WEEK.

MARINE...NOW THROUGH SATURDAY...BUOY 42020 REPORTED EAST WINDS
AROUND 16 KNOTS GUSTING TO AROUND 19 KNOTS WITH SEAS SLIGHTLY UNDER
6 FEET WITH A PERIOD OF 7 SECONDS AT 03 CST/09 UTC. GENERALLY
MODERATE WINDS AND SEAS ARE EXPECTED ALONG THE LOWER TEXAS COAST
TODAY AND TONIGHT IN ADVANCE OF A COLD FRONT. SMALL CRAFT WILL
LIKELY NEED TO EXERCISE CAUTION FOR A PORTION OF THE GULF OF MEXICO
WATERS EAST OF PADRE ISLAND TODAY DUE TO SEAS. THE PASSAGE OF A
STRONG COLD FRONT THROUGH THE LOWER TEXAS COASTAL WATERS SATURDAY
MORNING WILL BRING MUCH MORE ADVERSE MARINE CONDITIONS TOMORROW...
WITH SMALL CRAFT ADVISORIES LIKELY AND GALE WARNINGS INCREASINGLY
LIKELY.

SATURDAY NIGHT THROUGH FRIDAY...AS THE SURFACE HIGH BUILDS INTO
THE GULF WATERS SMALL CRAFT ADVISORY ARE POSSIBLE ACROSS THE GULF
WATERS AND LAGUNA MADRE WITH STRONG NORTHERLY WINDS. LATE MONDAY
SURFACE HIGH SHIFTS TO THE EAST VEERING EAST TO SE BY MONDAY NIGHT
INTO TUESDAY WITH MODERATE WINDS. AS THE NEXT SYSTEM DEVELOPS...
HIGHER VALUES OF MOISTURE WILL BE CONCENTRATED OVER THE AREA
ALLOWING FOR CHANCE OF SHOWERS AND THUNDERSTORMS WED THROUGH FRI.
THE SE WINDS INCREASE AND BUILD SEAS WITH THE POTENTIAL FOR SCA
POSSIBLE WED AND THU.
