NATIONAL WEATHER SERVICE CORPUS CHRISTI TX
943 PM CDT TUE APR 12 2016

.DISCUSSION...GFE FORECAST MONITOR CONTINUES TO SHOW GREEN FOR
TEMP/DEWPOINT/RH AND ALMOST ALL WINDS. ERGO...NO NEED TO UPDATE
FORECAST. MARINE FORECAST IS WORKING OUT FINE. SMALL SCALE MODELS
AND RECENT OTHER GUIDANCE SUGGESTS MORE DEVELOPMENT AFTER MIDNIGHT
BUT LIKELY TRANSITION WILL BE FROM A POTENTIAL FOR SEVERE TO
STRONG STORMS AND MAIN CONCERNS BEING HEAVY RAINFALL. THUS...SEE
NO NEED TO MAKE ANY CHANGES AT THIS TIME. MARINE FORECAST IS GOING
FINE AT THIS TIME.

CONCERNING SEVERE WATCH 87...ANOTHER BORDERLINE SEVERE EVENT
(OFTEN THE CASE HERE IN SOUTH TEXAS) AND THERE IS STILL A CHANCE
SOME SEVERE STORMS COULD GET MAINLY INTO LA SALLE AND MCMULLEN
COUNTIES IN THE NEXT FEW HOURS. CAP/CIN IS INCREASING BUT STILL
SOME GOOD STORMS OUT TO THE WEST. ERGO...WATCH REMAINS IN PLACE.
TRENDS WILL BE MONITORED AND UPDATES WILL BE ISSUED AS-NEEDED.

.PREV DISCUSSION... /ISSUED 744 PM CDT TUE APR 12 2016/

DISCUSSION...SEVERE THUNDERSTORM WATCH TO BE ISSUED FOR NORTHERN
TIER OF COUNTIES THROUGH 1 AM. WILL UPDATE WHEN WCN IS ISSUED. FOR
NOW...POPS LOOK GOOD.

PREV DISCUSSION... /ISSUED 556 PM CDT TUE APR 12 2016/

DISCUSSION...SEE 00Z AVIATION DISCUSSION.

AVIATION...CONDITIONS WILL DETERIORATE THIS EVENING AND OVERNIGHT
NOT ONLY WITH RESPECT TO CEILINGS...WITH IFR/LIFR CIGS DEVELOPING
MOST AREAS BY 13/06Z. CONCERNING THE CONVECTION...WILL HAVE SOME
SHOWERS MAINLY BEFORE 13/06Z...EXCEPT AT KLRD WHERE VCTS TO START
OFF AND TEMPO THUNDER BY 13/03Z. TIMING OF CONVECTION THEN MOVES
EAST MAINLY AFTER 13/05Z...WITH GUSTY WINDS (AOA 30 KNOTS).
STRONGEST CONVECTION (TEMPOS) AT KLRD BETWEEN 13/03Z AND
13/07Z...BETWEEN 13/07Z AND 13/11Z AT KVCT...AND BETWEEN 13/09Z-
10Z AND 13/13Z- 14Z AT KALI AND KCRP. WILL CONTINUE WITH THUNDER
FOR 3 TO 6 MORE HOURS AFTER EACH TEMPO FOR STRONGEST CONVECTION.
CIGS WILL GRADUALLY IMPROVE FROM WEST TO EAST...WITH VFR AT KLRD
AOA 19Z...ABOUT 20Z AT KALI AND KVCT...WITH MVFR CONTINUING AT
KCRP THROUGH THE END OF THE PERIOD (OR AT LEAST NOT CONFIDENT
ENOUGH TO WARRANT ANOTHER PERIOD IN A LONG FORECAST TO START).
EAST WINDS TONIGHT BECOME NORTHEAST THROUGH THE PERIOD...MORE
NORTH AT KLRD AND KVCT.

PREV DISCUSSION... /ISSUED 357 PM CDT TUE APR 12 2016/

SHORT TERM (TONIGHT THROUGH WEDNESDAY NIGHT)...INCREASING RAIN CHCS
EXPECTED TONIGHT INTO WED AS A WEAK BDRY STALLS ACROSS THE AREA WITH
A COASTAL TROUGH DRAPED TO ITS SE. THE BDRY...COMBINED WITH AN UPPER
SHORT WAVE AND A SPLIT UPPER LEVEL JET AND INCREASING MOISTURE WITH
2IN PWATS ACROSS E CWA...WILL LIKELY PRODUCE HEAVY RAINFALL LATE
TONIGHT INTO WED. MODEL SOUNDINGS ALSO SHOW A CONDUCIVE ENVIRONMENT
FOR EFFICIENT WARM RAIN PROCESSES ALONG WITH MODERATE INSTABILITY TO
THE E OF THE BDRY. THE HEAVIEST RAINFALL IS EXPECTED TO BE GENERALLY
ALONG AND EAST OF HIGHWAY 281 WITH AMOUNTS RANGING FROM 1 TO 3
INCHES AND LOCAL AMOUNTS UP TO 5 INCHES POSSIBLE. THEREFORE HAVE
ISSUED A FLASH FLOOD WATCH FOR THE EASTERN CWA BEGINNING AT 10Z
THROUGH 21Z WED. SOME MODELS SUGGEST HEAVY RAINFALL ACROSS THE W CWA
TONIGHT...BUT FEEL THE HEAVIER RAIN WILL NOT LAST AS LONG ACROSS THE
WEST AS IT IS EXPECTED TO DO ACROSS THE EAST. THAT BEING SAID...CAN
NOT RULE OUT LOCALIZED FLOODING ACROSS THE WESTERN CWA. THE MAIN
THREAT ACROSS THE W CWA IS TONIGHT FROM POSSIBLE SVR STORMS WITH
DAMAGING HAIL AND WIND BEING THE PRIMARY THREATS. THE STORM
PREDICTION CENTER HAS THE W CWA UNDER A SLIGHT RISK WITH A MARGINAL
RISK FARTHER E.

THE OVERALL PICTURE...AM EXPECTING THAT CONVECTION CURRENTLY
DVLPG S OF BIG BEND OVER MEX WILL BECOME BETTER ORGANIZED THROUGH
THE EVENING...POSSIBLY MOVG ACROSS THE W OR NW CWA CLOSER TO
MIDNIGHT. THIS SYSTEM IS THEN EXPECTED TO MORF INTO A WIDESPREAD
HEAVY RAIN MAKER AS IT CONTS TO SLOWLY MOVE E TOWARD EARLY WED
MORNING. SOME MODELS PROG THE HEAVY RAIN TO CONTINUE ALONG THE
COAST THROUGH WED AFTERNOON WHILE OTHER SHOW A DECREASING TREND AS
THE UPPER TROUGH EXITS THE REGION. FOR NOW WENT WITH A DECREASING
TREND WED AFTERNOON WITH ONLY A SLIGHT CHC REMAINING ACROSS THE
WATERS WED NIGHT.

LONG TERM (WEDNESDAY NIGHT THROUGH MONDAY)...WEDNESDAY NIGHT UPPER
TROUGH WILL BE MOVING EAST OF THE REGION...AND LAST OF CONVECTION
WILL BE MOVING OFFSHORE AND AWAY FROM SOUTH TEXAS.  THURSDAY AND
FRIDAY WILL BE DRY WITH WEAK RIDING DEVELOPING ALOFT. PWAT VALUES
WILL FALL BELOW 1 INCH ACROSS MOST LOCATIONS ON THURSDAY.
HOWEVER...NEXT LONGWAVE TROUGH/CLOSED LOW WILL DIG INTO THE SW CONUS
THURSDAY AND FRIDAY. POTENT UPPER LOW WILL MOVE OVER THE FOUR
CORNERS REGION BY SATURDAY. MOISTURE INCREASES ACROSS THE REGION
ONCE AGAIN FRIDAY INTO THE WEEKEND WITH STRENGTHENING ONSHORE FLOW.
SEEING SOME DIFFERENCES WITH PLACEMENT AND PROGRESSION OF THIS NEXT
SYSTEM...BUT MODELS ARE FAIRLY CONSISTENT IN KEEPING THIS LOW
CENTERED TO THE NORTHWEST OF THE REGION OVER THE WEEKEND BEFORE
PROGRESSING EASTWARD EARLY NEXT WEEK. KEPT WITH GENERALLY WIDESPREAD
HIGHER CHANCE POPS FROM MULTIPLE ROUNDS OF CONVECTION OVER THE
WEEKEND AND EARLY NEXT WEEK (WILL SEE BETTER TIMING AS EVENT DRAWS
CLOSER).

TIGHTENING PRESSURE GRADIENT FROM A SURFACE LOW OVER
NORTHCENTRAL/NORTHEAST MEXICO WILL STRENGTHEN ONSHORE FLOW OVER THE
WEEKEND.  BUILDING SEAS AND STRONG ONSHORE FLOW OVER THE GULF WATERS
MAY ELICIT SMALL CRAFT ADVISORIES DURING THIS TIME.

A GRADUAL WARMING TREND DEVELOPS AND BRINGS TEMPERATURES TO ABOVE
NORMAL VALUES THROUGH THE END OF THE WEEK.
