AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE BROWNSVILLE TX
1233 PM CDT FRI SEP 12 2014

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

&&

.AVIATION...SCATTERED SHOWERS AND THUNDERSTORMS IN THE AREA ARE
EXPECTED TO BECOME MORE NUMEROUS THROUGH THE AFTERNOON. VICINITY
THUNDER AND TEMPORARY THUNDERSTORM CONDITIONS ARE EXPECTED AT AREA
AIRFIELDS THROUGH 00Z. AN AREA OF MORE STRATIFORM RAIN IS ALSO
TRACKING INLAND. VISIBILITY OUTSIDE OF THUNDERSTORMS SHOULD HOLD
AT GREATER THAN 6SM BUT HEAVIER TSRA HAS TAKEN VISBY DOWN INTO THE
1 TO 2 MILE RANGE FOR ABOUT A HALF HOUR.

EXPECTING A BRIEF BREAK FROM HEAVIER ACTIVITY IN THE LATE
AFTERNOON AND EVENING BUT THE MAIN CORE OF THE TROPICAL WAVE WILL
ARRIVE TONIGHT. MAY BE A LITTLE TOO OPTIMISTIC ON VIS/CIG IN TAFS
AS RAIN AND LOCALLY HEAVY AND PERSISTENT RAIN IS IN THE GENERAL
FORECAST SATURDAY MORNING THROUGH EARLY SATURDAY AFTERNOON.
EMBEDDED THUNDERSTORMS ARE ALSO EXPECTED ESPECIALLY BETWEEN ABOUT
2 AM TO NOON OR SO. /68-JGG/

&&

.PREV DISCUSSION... /ISSUED 941 AM CDT FRI SEP 12 2014/

DISCUSSION...RADAR AND SATELLITE SHOW A DISTINCT UPTICK IN
CONVECTION OVER THE LAST 4 TO 6 HOURS OVER THE WESTERN GULF OF
MEXICO TO THE SOUTHEAST OF THE AREA. THIS APPEARS TO BE RELATED TO
SPEED DIVERGENCE AND DIRECTIONAL DIFFLUENCE ON THE NORTHERN
PERIPHERY OF A CLOSED UPPER LOW MOVING INLAND OVER TAMAULIPAS AND
NUEVO LEON STATE MEXICO. THIS LOW SHOULD CONTINUE TO TRACK WEST
NORTHWESTWARD AND RAP/NAM/GFS GUIDANCE SUGGEST THE JET MAXIMUM
PRODUCING THE SPEED DIVERGENCE WILL SLOWLY WEAKEN THROUGH THE DAY
BUT NOT BEFORE AIDING IN DEVELOPMENT OF CONVECTION OVER DEEP SOUTH
TEXAS THROUGH EARLY AFTERNOON AS IT MOVES INLAND.
EXPECTING NUMEROUS SHOWERS AND STORMS TO DEVELOP AND BEGIN TO WORK
INLAND IN A FEW HOURS. 12Z SOUNDING SHOWED MORE COLUMN MOISTURE
THAN ANTICIPATED...WITH A PRECIPITABLE WATER VALUE OF 2.3 INCHES
SO CONSIDERED BRINGING THE FLASH FLOOD WATCH START TIME FORWARD
BUT THE COVERAGE OF THIS CURRENT ACTIVITY LOOKS RIGHT NOW TO BE A
LITTLE TOO LOW TO CHANGE COURSE. THE WEAKENING OF THAT JET MAXIMUM
ALSO MAY LEAD TO A MODEST REDUCTION IN COVERAGE BY 5 TO 7 PM...BUT
THERE IS LARGE UNCERTAINTY ON WHETHER DAYTIME HEATING WILL BE
SUFFICIENT TO KEEP THE ATMOSPHERE UNSTABLE AND CONTINUE TO PRODUCE
LARGE COVERAGE THROUGH THE ENTIRE EVENING NEGATING THE EFFECTS OF
A SLIGHT REDUCTION IN SYNOPTIC FORCING.

WHEN THE CORE OF THE TROPICAL WAVE ARRIVES LATE TONIGHT AND EARLY
TOMORROW MORNING THE THREAT OF MORE WIDESPREAD HEAVY RAIN AND
PERSISTENT BANDING WILL INCREASE. SATELLITE IMAGERY AND MODEL
ANALYSIS SUGGESTS THIS FEATURE IS ON TRACK AND ON SCHEDULE. THE
FRONT OVER CENTRAL TEXAS IS STILL EXPECTED TO GET MOVING LATER
TODAY/TONIGHT AND STALL NEAR OR OVER THE BROWNSVILLE CWA ON
SATURDAY CONTINUING THE FLASH FLOOD THREAT. /68-JGG/

PREV DISCUSSION... /ISSUED 640 AM CDT FRI SEP 12 2014/

DISCUSSION...UPDATED FOR LATEST AVIATION DISCUSSION BELOW.

AVIATION...CONVECTION JUST SOUTHEAST OF KBRO WITH SCATTERED TO
NUMEROUS ACTIVITY OVER THE GULF OF MEXICO EAST AND SOUTHEAST OF
KBRO. ALL CONVECTION IS MOVING WEST. SHOWERS AND THUNDERSTORMS TO
INCREASE THROUGH THE DAY AND TONIGHT. DEEP TROPICAL MOISTURE WILL
COMBINED WITH AN UPPER LOW PRESSURE AREA, TROPICAL WAVE AND SEA
BREEZE TODAY. TONIGHT AND SATURDAY A COLD FRONT AND LOW PRESSURE
SURFACE TROUGH TO COMBINE WITH THE MOISTURE FOR WIDESPREAD SHOWERS
AND THUNDERSTORMS. VFR IS EXPECTED IN THE MOST PART TODAY BUT EXPECT
MVFR TO BRIEF IFR CONDITIONS WITHIN THE HEAVIER SHOWERS AND
THUNDERSTORMS. LIGHT TO MODERATE SOUTHEAST TO EAST FLOW TODAY AND
TONIGHT.

PREV DISCUSSION... /ISSUED 407 AM CDT FRI SEP 12 2014/

SHORT TERM /NOW THROUGH SATURDAY/... LATEST SYNOPTIC MAP SHOWS A
STATIONARY FRONT OVER THE TEXAS HILL COUNTRY WITH A TROPICAL WAVE
APPROACHING THE NORTHEAST COAST OF MEXICO. UPPER LEVELS SHOW A
WELL DEFINE LOW PRESSURE AREAS ALONG THE NORTHEAST MEXICAN COAST.
THESE THREE ELEMENTS WILL BE COMBINING OVER THE NEXT 24 TO 36
HOURS TO PRODUCE A POSSIBLE SUBSTANTIAL RAINFALL EVENT ACROSS THE
DEEP SOUTH TEXAS ESPECIALLY THE RIO GRANDE VALLEY.

FIRST OFF A FLASH FLOOD WATCH WILL BE ISSUED FOR COUNTIES ALONG THE
RIO GRANDE RIVER INCLUDING WILLACY, CAMERON, HIDALGO, STARR AND
ZAPATA FROM MIDNIGHT TONIGHT THROUGH SATURDAY. UPPER TROUGH OVER THE
NORTHERN PLAINS TO MOVE EAST TODAY WITH PRESSURE RISES ALONG THE
FRONT RANGE AND SOUTHERN PLAINS ALLOWING FOR THE STATIONARY FRONT TO
BEGIN MOVING SOUTH LATER TONIGHT. GFS/ECMWF AND HPC GUIDANCE ALL
AGREE THAT THE FRONT ENDS UP DRAPED ACROSS THE CWA SATURDAY MORNING.
A WAVE OF LOW PRESSURE OR A COASTAL TROUGH BEGINS TO INTENSIFY WITH
850-700MB FLOW STRENGTHENING. CONVERGENCE ALONG THE COASTAL TROUGH
AND LIFT WITHIN THE FRONTAL BOUNDARY PEAK BETWEEN MIDNIGHT AND 18Z
SATURDAY OVER MUCH OF EASTERN AND SOUTHERN COUNTIES. HEAVY RAIN WILL
LIKELY BE FOCUSED IN THE MORNING ALONG THE COAST AND LOWER MID
VALLEY THEN SHIFT WESTWARD AS THE EASTERLY FLOW DEEPENS ALONG THE
SIERRA MADRE LATER IN THE DAY. UPPER LOW TO AIDE IN DECENT DIVERGENT
FLOW WITH SUBSTANTIAL DEEP OMEGA OVERNIGHT. MOISTURE BEGINNING TO
INCREASE WITH SCATTERED CONVECTION OFFSHORE AND JUST SOUTH OF THE
RIVER. AS THE TROPICAL WAVE OVER THE SW GULF MOVES INLAND A URGE IN
TROPICAL MOISTURE IS EXPECTED. PWAT VALUES TO INCREASE NEAR 2.5
INCHES WHICH IS PLENTY OF JUICE FOR HEAVY TO TORRENTIAL RAINFALL.
AVERAGE RAINFALL AMOUNTS OF 2-4 INCHES WITH LOCALLY HIGHER AMOUNTS
TO 6 INCHES WILL BE FAVORED ACROSS THE WATCH AREA. SOME OF THIS RAIN
WILL OCCUR IN SHORT AMOUNT OF TIME WHICH WILL PRODUCE THE POSSIBLE
FLOODING. IF THE FRONT BECOMES THE MAIN FOCUS FEATURE THEN SOME
AREAS WITHIN THE FRONTAL BOUNDARY COULD SEE ISOLATED HIGHER
AMOUNTS.

AS FOR TODAY SCATTERED SHOWERS EARLY ON BECOME MORE NUMEROUS
LATER TODAY AS DAYTIME HEATING AND SEA BREEZE DEVELOPS. AS THE UPPER
LOW DRIFTS FARTHER WEST DIFFLUENT FLOW STRENGTHENS AND COMBINES WITH
CONVERGENCE OF THE SEA BREEZE. POPS HAVE BEEN LOWERED JUST A TAD BUT
MOST AREAS WILL SEE RAIN TODAY WITH THE BETTER CHANCES ARRIVING
TONIGHT AND SATURDAY MORNING AS THE FRONT ARRIVES IN THE AREA.

TEMPERATURES TODAY STILL RATHER WARM BUT A CATEGORY LOWER THEN
YESTERDAY DUE TO THE RAIN AND INCREASING CLOUD COVER. ANY OUTDOOR
PLANS WILL LIKELY BE A WASH OUT ON SATURDAY WITH POPS CLOSE TO 100
PERCENT. HIGH TEMPERATURES WILL BE GREATLY AFFECTED AND WILL SHOW
LITTLE INCREASE FROM SATURDAY MORNING LOWS.

THANKS TO CRP FOR COORDINATION.

LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/...MAIN RAINFALL EVENT
WILL BE ENDING ON SATURDAY NIGHT AS THE TROPICAL WAVE DEPARTS TO
THE NW AND H5 RIDGING SLOWLY BUILDS BACK ACROSS THE NW GULF. WHILE
THE DYNAMICS MAY BE LESSENED...MOISTURE REMAINS DENSE ACROSS THE
REGION. A SLOW RETURN OF DAYTIME HEATING WILL BRING THE SEABREEZE
INLAND AGAIN SUNDAY...WHICH MAY INTERACT WITH WHATEVER IS LEFT OF
THE STATIONARY FRONT TO BRING A CHANCE FOR RAINFALL AGAIN DURING
THE AFTERNOON. STARTING MONDAY...MIDLEVEL MOISTURE DECREASES AS H5
RIDGE CENTERS IN THE VICINITY. RIDGE IS WEAK...AND LOWER LEVEL
MOISTURE REMAINS HIGHER FROM FLOW OFF THE GULF...SO CHANCE FOR
SEABREEZE SHOWERS CONTINUES THROUGH THE MIDDLE OF NEXT WEEK. LATER
IN THE WEEK THE RIDGE SHIFTS OFF TO THE WEST...SETTING UP
NORTHERLY MIDLEVEL FLOW ALOFT. THIS USUALLY IS A DRYING
PATTERN...SO WILL MINIMIZE RAIN CHANCES FOR THURSDAY INTO FRIDAY.
TEMPERATURES WILL REMAIN NEAR TO SLIGHTLY ABOVE NORMAL. TEMPS WILL
HAVE A HARD TIME RISING FURTHER DUE TO AMPLE LLVL MOISTURE.

MARINE...
NOW THROUGH FRIDAY NIGHT... TODAY WIND AND SEAS START OFF LIGHT
AND LOW RESPECTIVELY WITH A STATIONARY FRONT OVER CENTRAL TEXAS.
EASTERLY SURFACE WINDS TO STRENGTHEN TONIGHT INTO SATURDAY AS A
COASTAL TROUGH DEVELOPS. EASTERLY FLOW TO MAY APPROACH SMALL CRAFT
ADVISORY LEVELS WITH SEAS RESPONDING OVERNIGHT. THE BRIEF INCREASE
BEGINS TO RELAX LATER SATURDAY AFTERNOON AS THE FRONT PULLS UP
STATIONARY ONCE AGAIN ALONG THE MID TO LOWER TEXAS COAST. SEAS MAY
LINGER LONGER THEN THE WINDS. SHOWERS AND THUNDERSTORMS ARE
EXPECTED AND WILL BE INCREASING THIS MORNING WITH WIDESPREAD
ACTIVITY OVERNIGHT AND SATURDAY. SEAS WILL LIKELY BE ROUGH AND
HIGHER NEAR THE THUNDERSTORMS.

SATURDAY NIGHT THROUGH TUESDAY...EARLY WEEK MARINE CONDITIONS WILL
IMPROVE AS EASTERLY FLOW DECREASES WITH THE DISSIPATION OF THE
LOCAL FRONTAL BOUNDARY. WINDS SHOULD GENERALLY REMAIN 10 TO 15
KNOTS...WHILE SEAS FALL FROM 6 FEET SATURDAY NIGHT DOWN TO AROUND
3 FEET BY TUESDAY MORNING.

...SHOWERS AND THUNDERSTORMS INCREASING IN COVERAGE...

DEEP TROPICAL MOISTURE OVER SOUTH TEXAS AND THE RIO GRANDE VALLEY
IS PROVIDING FUEL FOR INCREASING SHOWER AND THUNDERSTORM ACTIVITY
THIS AFTERNOON. THE MOISTURE IS BEING FOCUSED BY CONVERGENCE ALONG
AN AXIS OF LOWER PRESSURE FROM THE BAY OF CAMPECHE NORTH ALONG THE
NORTHEAST MEXICAN COAST.

SHOWERS AND THUNDERSTORMS WILL CONTINUE TO INCREASE IN COVERAGE
AND INTENSITY ACROSS THE COUNTY WARNING AREA TONIGHT THROUGH
SATURDAY MORNING AS A COLD FRONT MOVES INTO THE AREA AND STALLS.
THE BEST CHANCE FOR RAIN...INCLUDING HEAVY DOWNPOURS...WILL BE
SATURDAY. RAIN ACCUMULATION FOR MOST AREAS THROUGH SATURDAY WILL
BE TWO TO FOUR INCHES OF RAIN WITH ISOLATED AMOUNTS OF UP TO SIX
INCHES. AT A MINIMUM...THIS WILL LEAD TO NUISANCE FLOODING OF
URBAN AREAS...ARROYOS AND RESACAS...WITH ISOLATED FLASH FLOODING
POSSIBLE.

TAKE THE TIME TO CLEAN DRAINAGE CHANNELS SUCH AS ALONG THE SIDES
OF THE STREET AND MONITOR UPDATES.
