AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CORPUS CHRISTI TX
844 AM CDT MON APR 12 2010

.DISCUSSION...SENT QUICK UPDATE TO INCREASE POPS SOUTHERN AND
WESTERN CWA AND LOWER TEMPS BASED ON CURRENT RADAR TRENDS. UPDATES
OUT.

&&

.PREV DISCUSSION... /ISSUED 618 AM CDT MON APR 12 2010/

DISCUSSION...SEE AVIATION SECTION.

AVIATION...AN UPPER LEVEL DISTURBANCE WILL CONTINUE TO BRING
NUMEROUS SHRA'S/TSRA'S TO THE BRUSH COUNTRY AND ISOLD TO SCT
TOWARD THE EAST AS THE STORMS MOVE INTO INCREASINGLY STABLE AIR
AND LIMITED MOISTURE FARTHER E AND NE. LRD HAS THE BEST CHC OF
TSRA'S WHILE LESSER CHCS EXIST FOR ALI AND CRP TO THE LEAST CHC
ACROSS VCT. GENERALLY MVFR CONDITIONS WILL PREVAIL WITH PERIODS
OF IFR DURING SHRA'S/TSRA'S. RAIN CHCS DECREASE TONIGHT...HOWEVER
LOW CIGS AND PATCHY FOG ARE EXPECTED TO DVLP...ESPECIALLY FOR THE
VCT AREA.

PREV DISCUSSION... /ISSUED 348 AM CDT MON APR 12 2010/

SHORT TERM (TODAY THROUGH TUESDAY)...SHOWERS AND THUNDERSTORMS ARE
MOVG INTO THE EXTREME W CWA FROM MEXICO THIS MORNING. THIS IS IN
RESPONSE TO A SHORT WAVE MVG E ALONG WITH DIFFLUENCE ALOFT...LFQ OF
JET...MOD CAPE AND THETA-E RIDGING ALONG THE RIO GRANDE. CAPE IS
PROGD TO INCREASE THRU 18Z ACROSS THE W AND INTO THE CENTRAL
PORTIONS OF THE CWA WITH DECREASING CIN. HOWEVER...CIN REMAINS
FAIRLY HIGH ACROSS THE E AND NE WITH LOW CAPE AND LIMITED
MOISTURE. GIVEN THE CAPE AND UPPER SUPPORT ACROSS THE WEST CWA...AM
EXPECTING THAT SOME STORMS COULD BECOME STRONG TO POSSIBLY MARGINAL
PULSE SVR. THE UPPER JET IS PROGD TO SHIFT S THROUGH THE
DAY...WHICH WILL LEAD TO LESS SUPPORT BY 00Z ALONG WITH DECREASING
CAPE VALUES. THEREFORE AM EXPECTING THE BEST CHCS FOR TSRA'S WILL
BE THIS MORNING TO EARLY AFTERNOON ACROSS THE WEST HALF OF THE
CWA. THEN BY LATE AFTERNOON...PRECIP TYPE WILL BE MORE SHRA/RAIN
AS CAPE DECREASES ACROSS MOST OF THE CWA EXCEPT THE FAR W AND
ACROSS MEXICO. RAIN CHCS DECREASE OVERNIGHT BUT REMAIN IN THE LOW
END CHC CATEGORY ACROSS THE WEST DUE TO PROXIMITY TO A SECOND
SHORT WAVE MOVG ACROSS MEXICO. CAPE VALUES ARE LOW ACROSS THE WEST
TO NIL ACROSS THE EAST...THEREFORE AM ONLY MENTIONING SHRA'S
TONIGHT. THE CAPE INCREASES ON TUE HOWEVER THE UPPER JET IS
FARTHER S. A THIRD SHORT WAVE WILL APPROACH S TX BRINGING A CHC OF
TSRA'S ONCE AGAIN...MAINLY TO THE W AND S CWA DUE TO THE HIGHER
CAPE. THE NE CWA WILL REMAIN IN LOWER CAPE AND LIMITED MOISTURE.

MARINE...LOW PRESSURE ACROSS WEST TEXAS AND HIGH PRESSURE ACROSS
THE NORTHERN GULF WILL MAINTAIN A MODERATE EASTERLY FLOW TODAY
THROUGH TUESDAY. A SERIES OF UPPER DISTURBANCES WILL BRING ISOLD TO
SCT SHRA'S AND TSRA'S THROUGH TUE.

LONG TERM (TUESDAY NIGHT THROUGH SUNDAY)...THE MODELS REMAIN IN
GOOD AGREEMENT THROUGH THURSDAY WITH THE WET SYNOPTIC PATTERN.
PERSISTENT MID/UPR DIVERGENCE/DIFLUENCE AHEAD OF A SLOW-MOVING
MID/UPR TROUGH AXIS WL PREVAIL THROUGH THURSDAY ACROSS THE CWA.
MEANWHILE...DEEP MOISTURE TRANSPORT AHEAD OF THIS TROUGH AXIS WL
ALLOW PWS TO RISE TO AT LEAST 1.5 INCHES. MARGINAL TO MODERATE
INSTABILITY ALONG WITH NO CAP THANKS TO THE PREVAIL EASTERLY
BOUNDARY LAYER FLOW. THE RESULT WL BE SCATTERED CONVECTION THROUGH
THURSDAY ACROSS MUCH OF THE CWA...ESPECIALLY THE WESTERN AND CENTRAL
PORTIONS. THE DEEP MOISTURE AND WK 0-6KM SHEAR WL KEEP THE THREAT
FOR ORGANIZED SVR STORMS AT A MINIMUM.  THE MAIN ISSUE WL INSTEAD BE
LOCALIZED HVY RAIN GIVEN THE SLOW MOVEMENT OF STORMS.  ONCE AGAIN
THE MODELS BEGIN TO DIVERGE BY FRIDAY. THE ECMWF SOLN REMAINS THE
WETTEST SOLN SINCE IT MAINTAINS A SHARPER AND SLOWER TROUGH AXIS.
THE GFS REMAINS THE DRIEST SOLN SINCE IT WEAKENS AND PUSHES THIS
TROUGH AXIS FURTHER EAST. FOR CONSISTENCY PURPOSES...WL LEAN TWDS
THE GFS SOLN FOR NOW.  HOWEVER...WL STILL MAINTAIN AT LEAST SLIGHT
CHC POPS THROUGH THE WEEKEND AS THERE WL LKLY BE AT LEAST RESIDUAL
MOISTURE ALONG WITH SUFFICIENT INSTABILITY AND WK TO NIL CAPPING.
WL BEGIN A SLOW WARMING TREND ON FRIDAY (MAINLY FOR HIGHS) AS SUBTLE
DRYING BEGINS.
