AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE BROWNSVILLE TX
921 PM CDT MON MAY 12 2014

.DISCUSSION...ATMOSPHERIC CONDITIONS CONTINUE TO BE UNSTABLE THIS
EVENING ESPECIALLY ACROSS THE WESTERN ZONES WHERE A FEW
THUNDERSTORMS HAVE MOVED ACROSS THE RIVER INTO STARR COUNTY. A
CELL MERGER NEAR AND NORTHEAST OF ROMA COULD PRODUCE 2+ INCHES OF
RAIN THROUGH 930 PM. OTHER CELLS ARE MOVING INTO WEBB COUNTY
NORTH OF THE CWA WITH ADDITIONAL CELLS JUST WEST OF ZAPATA COUNTY.
ALTHOUGH THE SEVERE THREAT LOOKS TO BE WANING THIS EVENING A
THREAT CONTINUES OVERNIGHT AND INTO TUESDAY MORNING FOR HEAVY RAIN
WITH ISOLATED STRONG WIND GUSTS AND HAIL.

A SLOW MOVING COLD FRONT AND HIGH ATMOSPHERIC MOISTURE CONTENT TO
COMBINE WITH AN UPPER TROUGH AND AN INCREASINGLY DIFFLUENT FLOW TO
MAINTAIN A HIGH CHANCE OF RAIN OVER THE NEXT 12-30 HOURS OR
THROUGH LATE TUESDAY NIGHT. MODELS AND SATELLITE LOOPS SUGGEST
THAT THE SUBTROPICAL JET OVER THE EASTERN PACIFIC TO TRANSPORT
HIGH LEVEL MOISTURE ACROSS NORTHERN MEXICO AND SOUTH TEXAS TUESDAY
AND WILL COMBINE WITH A LONG FETCH OF ESE GULF OF MEXICO
MOISTURE. PRECIPITABLE WATERS AMOUNTS EXPECTED TO EXCEED 2 INCHES
TUESDAY WHICH WILL MAKE ANY THUNDERSTORM VERY EFFICIENT RAIN
MAKERS. QUESTION REMAINS ON HOW WIDESPREAD THE HEAVY RAIN BECOMES
IF THE STORMS WILL BE SLOW MOVING AS THEY CURRENTLY ARE OVER THE
HILL COUNTY AND NORTHEAST PORTIONS OF TEXAS. OVERNIGHT SHIFT WILL
HAVE A NEW MODEL SUITE TO LOOK AT AND DETERMINE IF A FLASH FLOOD
WATCH WILL BE WARRANTED FOR PORTIONS OF DEEP SOUTH TEXAS INCLUDING
THE RIO GRANDE VALLEY. MEDIA AND RESIDENTS SHOULD CONTINUE TO
MONITOR THE NWS FOR LATER UPDATES AND OR POSSIBLE
WATCHES...ADVISORIES OR WARNINGS.

&&

.PREV DISCUSSION... /ISSUED 631 PM CDT MON MAY 12 2014/

DISCUSSION...UPDATED FOR LATEST AVIATION DISCUSSION BELOW.

AVIATION...THUNDERSTORMS DEVELOPING WEST OF THE RIO GRANDE RIVER TO
APPROACH THE WESTERN COUNTIES BETWEEN 7 AND 8 PM THEN TRACK ENE
POSSIBLY APPROACHING KMFE BETWEEN 9 AND 10 PM AND AREAS NORTH AND
EAST AFTER 10 PM. A SLOW MOVING COLD FRONT OVER NORTH CENTRAL
TEXAS TO MOVE INTO SOUTH TEXAS TUESDAY PROVIDING WIDESPREAD
RAINFALL WITH SCATTERED TO NUMEROUS AREAS OF CONVECTION. IN
ADVANCE OF THE THUNDERSTORMS LOW CLOUDS TO PROVIDE MVFR TO
POSSIBLY IFR FLIGHT CATEGORIES TONIGHT. IFR TO LOW MVFR CONDITIONS
ARE EXPECTED WITH THE CONVECTION AND PERSIST THROUGH THE DAY
TUESDAY AS THE RAIN CHANCES REMAIN 60 PERCENT OR HIGHER. NON-
CONVECTIVE WINDS OF 15 TO 25 KNOTS THIS EVENING TO DIMINISH
THROUGH THE EVENING HOWEVER PERIODS OF STRONGER WINDS ARE LIKELY
WITH THE EXPECTED CONVECTION.

PREV DISCUSSION... /ISSUED 226 PM CDT MON MAY 12 2014/

SHORT TERM /NOW THROUGH TUESDAY NIGHT/...CURRENT WATER VAPOR
IMAGERY SHOWS THE BROAD UPPER LEVEL TROUGH ACROSS THE FRONT RANGE
OF THE ROCKIES. THE ASSOCIATED COLD FRONT EXTENDS FROM JUST WEST
OF DALLAS TO JUNCTION CITY TO THE NEAR THE BIG BEND EARLY THIS
AFTERNOON. CURRENT SATELLITE IMAGES AND SURFACE OBSERVATIONS
INDICATE PARTLY CLOUDY TO MOSTLY CLOUDY SKIES ACROSS THE REGION
EARLY THIS AFTERNOON.

THE TIGHT PRESSURE GRADIENT WILL MAINTAIN BREEZY SOUTHEAST
WINDS...MAINLY ALONG AND EAST OF HIGHWAY 281/INTERSTATE 69C...
THROUGH THIS AFTERNOON BEFORE DECREASING LATER THIS EVENING. DEEP
GULF MOISTURE WILL CONTINUE TO ADVECT INTO THE AREA DUE TO THE
PERSIST SOUTHEASTERLY FLOW. AN UPPER LEVEL DISTURBANCE OVER NORTHERN
MEXICO WILL MOVE ALONG IN THE SOUTHEAST FLOW ALOFT AND WILL MOVE
OVERHEAD LATER THIS AFTERNOON INTO THIS EVENING. THIS WILL RESULT IN
SHOWERS AND ISOLATED THUNDERSTORMS DEVELOPING OVER NORTHERN MEXICO
AND GRADUALLY MOVING INTO THE WESTERN COUNTIES LATER THIS AFTERNOON
THROUGH AROUND MIDNIGHT. WILL MAINTAIN A SLIGHT CHANCE OF POPS
ACROSS THE COASTAL COUNTIES THIS EVENING DUE TO THE WEAKEN CAPPING.
THE COLD FRONT WILL CONTINUE TO PROGRESS SOUTHEASTWARD OVERNIGHT
WITH THE FRONT GENERALLY EXTENDING FROM NORTHEAST TEXAS INTO THE
HILL COUNTRY THEN SOUTH OF EAGLE PASS. LOW TEMPERATURES TONIGHT WILL
BE IN THE MID 70S UNDER CLOUDY SKIES.

THE MID LEVEL THROUGH MOVES FARTHER EAST TUESDAY MORNING WITH THE
COLD FRONT APPROACHING THE NORTHWEST PORTIONS OF THE AREA BY LATE
TUESDAY MORNING INTO EARLY AFTERNOON HOURS CLOUDY SKIES. ORGANIZED
CONVECTION/POSSIBLE SQUALL LINE IS EXPECTED TO MOVE ACROSS THE DEEP
SOUTH TEXAS ON TUESDAY...PROVIDING A GOOD CHANCE OF SHOWERS AND
THUNDERSTORMS. HIGH TEMPERATURES ON TUESDAY WILL BE IN THE LOW TO
MID 80S DUE TO ABUNDANT CLOUDINESS AND MOISTURE.

MAIN CONCERNS ON TUESDAY WITH THIS SYSTEM WILL BE THE POSSIBILITY OF
STRONG TO SEVERE STORMS AND HEAVY RAINFALL. THE ENTIRE FORECAST AREA
IS OUTLOOKED IN A GENERAL THUNDERSTORM RISK THROUGH LATE TUESDAY
NIGHT. DEEP LAYER MOISTURE...STEEP MID-LEVEL LAPSE RATES AND
DIRECTIONAL SHEAR COULD PRODUCE SOME STRONG TO MARGINALLY SEVERE
THUNDERSTORMS ON TUESDAY. HOWEVER...THE COLD FRONT MAY MOVE THROUGH
THE AREA BEFORE AFTERNOON PEAK HEATING AND MOST OF THE INSTABILITY
SHOULD REMAIN NORTH OF THE AREA. THAT BEING SAID...WIDESPREAD
SHOWERS AND THUNDERSTORMS EXPECTED ON TUESDAY...SOME STORMS COULD
PRODUCE LARGE HAIL AND DAMAGING STRAIGHT LINE WINDS OF 60 MPH.

HEAVY RAINFALL IS POSSIBLE ON TUESDAY DUE TO THE HIGH PRECIPITABLE
WATERS VALUES /EXCEEDING 2.10 INCHES/ AND THE SLOW PROGRESSION OF
THE COLD FRONT ACROSS THE AREA. THE LATEST DAY 1-2 QPF VALUES
INDICATE 1 TO 3 INCHES OF RAINFALL WITH HEAVY AMOUNTS OF 2 TO 4
INCHES POSSIBLE ACROSS PORTIONS OF THE RIO GRANDE VALLEY AND DEEP
SOUTH TEXAS THROUGH LATE TUESDAY NIGHT. ANY FLOODING THAT OCCURS IS
EXPECTED TO BE MORE SHORT LIVED LOCALIZED NUISANCE FLOODING WITH THE
STRONGER AND SLOWER MOVING SHOWERS AND THUNDERSTORMS.

THE COLD FRONT MOVES OFF THE COAST BY MIDNIGHT WITH SHOWERS AND
THUNDERSTORMS LINGERING ACROSS PORTIONS OF THE RIO GRANDE VALLEY AND
DEEP SOUTH TEXAS LATE TUESDAY NIGHT. OVERNIGHT LOW TEMPERATURES
TUESDAY NIGHT WILL RANGE FROM THE UPPER 50S ACROSS THE NORTHERN
RANCHLANDS TO THE LOWER 60S ACROSS THE LOWER VALLEY AND ALONG THE
COAST.

LONG TERM /WEDNESDAY THROUGH MONDAY/...THE COLD FRONT WILL BE
LOCATED OFFSHORE OF DEEP SOUTH TX BY EARLY WED AS THE 500 MB TROUGH
AXIS EXITS THE REGION LATE WED AND WED NIGHT. THIS WILL ALLOW MUCH
DRIER AIR TO FILTER INTO THE REGION ALLOWING THE POTENTIAL FOR CONV
TO RAPIDLY DIMINISH WED. 500 MB RIDGING WILL THEN BUILD OVER THE
AREA THROUGHOUT THE END OF THE WEEK THROUGHOUT THE WEEKEND INTO MON.
AFTER A BRIEF COOL DOWN AFTER THE FRONT...THE TEMPERATURES WILL BE
ON THE INCREASE THROUGH NEXT MON AS THE SURFACE WAA RETURNS AND THE
DIURNAL HEATING EFFECTS KICK BACK IN.

THE GFS AND ECMWF SHOW DECENT MODEL TO MODEL AGREEMENT WITH THE
PLACEMENT OF THE LARGER SYNOPTIC SCALE FEATURES. ALSO THE GFS MEX
MOS SHOWS DECENT RUN TO RUN CONSISTENCY. HOWEVER THE ECMWF IS
QUICKER AND STRONGER WITH THE WARMUP VERSUS THE GFS MEX MOS
GUIDANCE. BELIVE THAT THE GFS IS TOO SLOW IN REFLECTING THE WARMUP
AND WILL BE LEANING MORE TOWARDS THE ECMWF FOR HIGHS AND LOWS
THROUGH DAY 7.  OVERALL CONFIDENCE IN THE LONGER RANGE FORECAST
WORDING IS ABOVE AVERAGE GIVEN THE GOOD MODEL AGREEMENT IN THE
SYNOPTIC PATTERN.

MARINE...NOW THROUGH TUESDAY NIGHT...BUOY 42020 REPORTED SOUTHEAST
WINDS AROUND 13 KNOTS WITH GUSTS OF 18 KNOTS AND SEAS OF 5.2 FEET AT
1350 PM CDT/1850 UTC. MARINE OBSERVATION PLATFORMS ALONG THE LAGUNA
MADRE THIS AFTERNOON INDICATE SOUTHEAST WINDS BETWEEN 16 TO 22
KNOTS. A SMALL CRAFT ADVISORY FOR WINDS REMAINS IN EFFECT THROUGH 7
PM THIS EVENING. THERE IS A POSSIBILITY SMALL CRAFT ADVISORY
CONDITIONS TONIGHT ACROSS THE LOWER TEXAS GULF WATERS AS THE
PRESSURE GRADIENT STRENGTHENS AGAIN.

THE PRESSURE GRADIENT WILL STRENGTHEN ALONG THE LOWER TEXAS COAST
THROUGH THE FORECAST PERIOD AS A COLD FRONT APPROACHES THE AREA.
MODERATE TO STRONG ONSHORE FLOW WILL CONTINUE TONIGHT THROUGH
TUESDAY EVENING BECOMING NORTHERLY LATE TUESDAY NIGHT. SMALL CRAFT
ADVISORIES WILL LIKELY BE NEEDED FOR THE LOWER TEXAS GULF WATERS
TUESDAY NIGHT. SHOWERS AND THUNDERSTORMS ARE IN THE FORECAST TONIGHT
THROUGH TUESDAY NIGHT AS AS UPPER LEVEL DISTURBANCE MOVES OVERHEAD
TONIGHT AND A COLD FRONT MOVES ACROSS THE REGION TUESDAY AND TUESDAY
NIGHT.

WEDNESDAY THROUGH SATURDAY...THE STRONG POST FRONTAL PGF PREVAILING
OVER THE LOWER TX MARINE AREAS ON WED WILL LIKELY REQUIRE SCAS ON
INTO WED. THE PGF WILL THEN WEAKEN BELOW SCA LEVELS WED NIGHT INTO
THURS AS A MORE ONSHORE FLOW RETURNS. SURFACE RIDGING OVER THE GULF
OF MEX WILL THEN MAINTAIN A LIGHT TO MODERATE SE SURFACE FLOW INTO
FRI AND SAT WITH LOWER SEAS PREVAILING.
