Area forecast discussion, Apr 14, 6:46 AM CDT, 11 minutes before

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE CORPUS CHRISTI TX
646 AM CDT TUE APR 14 2015

.DISCUSSION...UPDATED FOR THE 12Z AVIATION DISCUSSION.

&&

.AVIATION...ONGOING SCATTERED CONVECTION COVERING SOUTH TEXAS
WILL CONTINUE THROUGH THE MORING HOURS...WITH ADDITIONAL
CONVECTION MOVING IN FROM THE WEST ACROSS THE US/MEX BORDER. WILL
SEE LIFR/IFR CONDITIONS THIS MORNING...ESPECIALLY WITHIN AND NEAR
THUNDERSTORMS. ISOLATED THUNDER SHOULD ALSO EXTEND NORTH TOWARD
VCT...BUT THE HEAVIEST MORNING ACTIVITY EXPECTED TO AFFECT AREAS
FROM LRD-ALI-CRP. THUNDERSTORMS THIS MORNING MAY OVERWORK THE
ATMOSPHERE LEADING TO SLIGHTLY QUIETER WEATHER THIS
AFTERNOON...HOWEVER ISOLATED SHOWERS AND THUNDERSTORMS MAY STILL
LINGER AROUND WITH ENOUGH HEATING. OVERALL...MVFR CIGS ARE
EXPECTED THIS AFTERNOON...BUT BRIEF PERIODS OF VFR MAY EXIST. A
RETURN OF LOW CIGS IS EXPECTED OVERNIGHT.

&&

.PREV DISCUSSION... /ISSUED 419 AM CDT TUE APR 14 2015/

SHORT TERM (TODAY AND TONIGHT)...ONE SHORTWAVE MOVING THROUGH
THIS MORNING HELPING TO SUSTAIN CONVECTION ACROSS WESTERN PORTIONS
OF CWA. A FEW STORMS HAVE BEEN STRONG...AND THIS COULD CONTINUE TO
BE THE CASE AS THIS CONVECTION PROGRESSES EASTWARD TOWARD THE
COAST INTO EVEN MORE MOIST AIR. WEAK SURFACE FRONTAL BOUNDARY
REMAINS TO THE NORTH OF THE AREA...BETWEEN THETA E AND WIND
ANALYSES...APPEARS TO BE BETWEEN SAN ANTONIO AND PLEASANTON.
EXPECT THE FRONT TO SAG SOUTH DURING THE DAY...WITH ANOTHER
SHORTWAVE FORECAST TO MOVE THROUGH LATER TODAY. WITH DAYTIME
HEATING...SHOULD ERODE THE CAP ONCE AGAIN THIS AFTERNOON. ABUNDANT
MOISTURE AND FAIR SHEAR ALONG WITH CAPE COULD ALLOW FOR SOME
STRONG STORMS TO DEVELOP. EXPECT AN ISOLATED NATURE OF STRONGER
STORMS...MAINLY A HAIL THREAT. CANT COMPLETELY RULE OUT A SEVERE
STORM OR TWO. STRONGEST STORMS SHOULD BE ALONG OR SOUTH OF THE
WEAK FRONTAL BOUNDARY...SO WILL HAVE TO KEEP AN EYE ON WHERE THAT
STALLS THIS AFTERNOON. SHOULD SEE CONVECTION WEAKEN TONIGHT.

LONG TERM (WEDNESDAY THROUGH MONDAY)...THE WASHED OUT WEAK BOUNDARY
WILL SHUNT MOISTURE ACROSS THE SOUTHEASTERN HALF OF THE
CWA...DECREASING POPS FROM WEST TO EAST THROUGH WEDNESDAY NIGHT INTO
THURSDAY MORNING. A PERSISTENT SOUTHWESTERLY FLOW REMAINS IN THE MID
TO UPPER LEVELS AHEAD OF THE NEXT APPROACHING TROUGH. MOISTURE
RETURNS TO AREA THURSDAY SHOWING DIFFERENCES IN PWAT VALUES AMONGST
MODELS...BUT OVERALL THE TREND CONTINUES TO SHOW PWATS PEAKING TO
1.5 TO 1.7 INCHES IN THE AFTERNOON. THIS COMBINED WITH THE SOUTHWEST
FLOW IN THE MIDLEVELS AND THE UPPER JET STREAK NUDGING NORTH FROM
THE WEST WILL KEEP SCATTERED SHOWERS AND THUNDERSTORMS IN THE
FORECAST...PEAKING IN THE AFTERNOON AND EVENING. THURSDAY LOOKS TO
BE LIKE AN INTERESTING DAY AS CAPE VALUES INCREASE AND RANGE BETWEEN
2000-3000 J/KG. MODELS DO VARY ON THE STRENGTH OF LOW LEVEL INFLOW
IN THE AFTERNOON BUT OVERALL A 10-20 KT SOUTHEAST FLOW IS EXPECTED
TO EXIST. THIS ALL COMBINED COULD LEAD TO ANOTHER DAY OF STRONG TO
POSSIBLY ISOLATED SEVERE STORMS FOR SOUTH TEXAS. BETTER CHANCES FOR
THE STRONG TO EVEN SEVERE POSSIBILITY WILL RESIDE ACROSS THE WESTERN
AREAS WHERE BETTER THETA-E ADVECTION EXISTS. THIS SAID...SPC HAS
MUCH OF THE CWA IN A MARGINAL RISK FOR SEVERE THUNDERSTORMS.

MODELS THEN DIVERGE WITH RESPECT OF THE UPPER TROUGH FOR LATE IN THE
WORK WEEK. MODELS DO SEEM TO AGREE WITH A CUT OFF LOW DEVELOPING
FROM THE TROUGH...SLOWLY PROGRESSING EASTWARD FRIDAY. GFS CONTINUES
TO BRING A FRONT THROUGH THE REGION FRIDAY DRYING THINGS COMPLETELY
IN TIME FOR THE WEEKEND...WHILE THE EURO/CANADIAN AND IMPLICATIONS
FROM THE NAM TEND TO SHOW A MUCH SLOWER PROGRESSION OF THE LOW. WITH
DIFFERENCES EVEN BETWEEN THE GFS ENSEMBLES...WILL CONTINUE TO GO FOR
A SLOWER PROGRESSION OF DRYING OUT ACROSS THE REGION...WITH CHANCES
TAPERING OFF SATURDAY NIGHT AND DRIER CONDITIONS IN STORE BY SUNDAY.

NEAR SEASONAL NORMALS CAN BE EXPECTED THROUGH MUCH THE PERIOD.
