AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE CORPUS CHRISTI TX
910 PM CDT THU MAR 29 2012

.DISCUSSION...AS THE MESOSCALE CONVECTIVE VORTEX LIFTED INTO
SOUTHEAST TEXAS LATE THIS AFTERNOON...AIR MASS BECAME STRONGLY
UNSTABLE OVER THE COASTAL PLAINS WITH LIFTED INDECES AROUND -10
DEGREES AND CAPE VALUES AROUND 3000 J/KG. STRONG TO SEVERE
STORMS DEVELOPED ALONG THE SEA BREEZE WITH THE MOST SEVERE
AFFECTING ROBSTOWN WITH DAMAGING WINDS AND HAIL UP TO 2 INCHES.
MOST OF THE ACTIVITY DIMINISHED WITH THE LOSS OF HEATING AND
WEAK STABILIZATION BEHIND THE SEA BREEZE. BUT MORE ACTIVITY
LINGERING OVER DEEP SOUTH TEXAS HAS SHOWN A DRIFT TO THE
NORTHEAST AHEAD OF AN UPPER LEVEL SHORT WAVE TROUGH NORTH
OF MONTERREY MOVES EAST-NORTHEAST. WILL MODIFY POPS TO SHOW
BEST CHANCES FROM SOUTHWEST TO LIMITED NORTHEAST AND OVER THE
GULF WATERS. MODELS SHOW THIS VERY UNSTABLE AIRMASS TO REMAIN
OVER THE REGION FOR FRIDAY. FORECAST INSTABILITY FIELDS SHOW
CAPE FROM 3500-4000 J/KG OVER THE INLAND COASTAL PLAINS AND
BRUSH COUNTRY WITH LIFTED INDEX VALUES AROUND -11 TO -12
DEGREES WITH LIMITED CONVECTIVE INHIBITION. RAISED POPS TO
LOW END CHANCE OVER MOST OF THE BRUSH COUNTRY TO INLAND COASTAL
PLAINS FRIDAY AFTERNOON. POTENTIAL FOR ISOLATED SEVERE
THUNDERSTORMS AGAIN TOMORROW AFTERNOON INTO THE EVENING.

&&

.PREV DISCUSSION... /ISSUED 642 PM CDT THU MAR 29 2012/

DISCUSSION...SEE AVIATION SECTION BELOW.

AVIATION...ONGOING CONVECTION ALONG A SEA BREEZE THIS AFTERNOON
WILL CONTINUE TO MOVE SLOWLY WEST THRU THE EVENING HOURS. AREAS
AHEAD OF AND IN THE WAKE OF THE SEA BREEZE ARE GENERALLY VFR.
THESE STORMS ARE EXPECTED TO DIMINISH OVER THE NEXT TWO TO THREE
HOURS...HOWEVER THUNDERSTORMS ACROSS MEX ARE EXPECTED TO AFFECT
LRD LATER THIS EVENING TOWARD MIDNIGHT. THIS SYSTEM IS EXPECTED TO
GENERALLY MOVE E TO SE OVERNIGHT ACROSS S TX. GENERALLY MVFR CIGS
ARE EXPECTED TO DVLP OVERNIGHT WITH IFR/LIFR CONDITIONS IN AND
NEAR TSRA'S. ONCE THIS STORM SYSTEM HAS EXITED THE AREA...VFR
CONDITIONS ARE EXPECTED TO DVLP BY FRI AFTERNOON.

PREV DISCUSSION... /ISSUED 333 PM CDT THU MAR 29 2012/

SHORT TERM (TONIGHT THROUGH FRIDAY NIGHT)...ATMOSPHERE WAS PRETTY
WORKED OVER TODAY FROM LAST NIGHT/S CONVECTION WITH REMNANT MCV
NOTED ACROSS HGX CWA. LOW CLOUD DECK HAS BEEN SLOW TO MIX OUT
ACROSS BRUSH COUNTRY...BUT IS FINALLY STARTING TO DO SO AND ALL IN
ALL ATMOSPHERE IS GRADUALLY BECOMING MORE UNSTABLE AGAIN. PATTERN
LOOKS MORE LIKE MAY THAN MARCH WITH VORT MAXES TRAVERSING ACROSS
SOUTH TX IN THE MID LEVEL FLOW PRODUCING CONTINUING CHANCES OF
SHOWERS AND THUNDERSTORMS. OVER THE PAST HOUR CONVECTION HAS BEEN
TRYING TO FIRE ALONG THE SEABREEZE AS IT MOVES INLAND. THE
COMBINATION OF AN INCREASINGLY UNSTABLE AIRMASS AND AN AXIS OF
HIGHER PWATS DRAPED FROM SW TO NE ACROSS THE COASTAL PLAINS SHOULD
ALLOW ADDITIONAL CONVECTION TO DEVELOP ALONG THE SEABREEZE THROUGH
EARLY EVENING. ATTENTION THEN TURNS TO THE WEST WHERE CONVECTION
IS CURRENTLY DEVELOPING ACROSS HIGHER TERRAIN OF OLD MEX. HIRES
MODELS PROVIDE A VARIETY OF OUTPUT WITH 4KM WRF DEVELOPING
SIGNIFICANT CONVECTION ACROSS MUCH OF S TX THIS EVENING WHILE HRRR
IS MORE OF THE ISOLATED VARIETY. HRRR INITIALIZED MUCH BETTER THAN
4KM WRF SO HAVE LEANED MORE TOWARDS ITS OUTPUT FOR TONIGHT.
TRIMMED POPS SOME FOR TONIGHT OUT WEST BUT NOT AS DRY AS HRRR
GIVEN UNCERTAINTY. ANY STORMS THAT DEVELOP MAY BRIEFLY PULSE TO
STRONG/SEVERE LEVELS BUT WIDESPREAD SEVERE WX IS NOT CURRENTLY
ANTICIPATED. TOMORROW S TX IS PROG TO BE IN BETWEEN VORT MAXES AND
SHOULD GENERALLY BE DRY ASIDE FROM ISOLATED CONVECTION DEVELOPING
FROM DAYTIME MIXING AND INTERACTIONS WITH THE SEABREEZE. STRONGER
VORT MAX PROG TO APPROACH AREA FRI NIGHT WITH GOOD
PVA...INSTABILITY...AND MOISTURE TO EXIST FOR MCS FEATURE TO
POSSIBLY DEVELOP ALONG RIO GRANDE AND MOVE WEST THROUGH THE NIGHT.
STRONG WINDS AND HAIL MAY OCCUR IF MCS DEVELOPS BUT FINER DETAILS
TO COME IN FUTURE FORECASTS. TEMPS THROUGH THE SHORT TERM PERIOD
WILL BE DEPENDENT ON IF THEY BECOME RAIN COOLED AND HOW MUCH CLOUD
COVER DEVELOPS FROM CONVECTION. FOR NOW HAVE GONE GENERALLY WITH A
MOS BLEND.

LONG TERM (SATURDAY THROUGH THURSDAY)...EXPECT NOCTURNAL MCS TO BE
MOVING OUT OF THE FORECAST AREA BY THE START OF THE EXTENDED PERIOD.
HAVE ADDED 20 POPS TO THE FAR EAST TO ACCOUNT FOR TIMING OF THE
CONVECTION POSSIBLY LASTING INTO THE SATURDAY MORNING TIME PERIOD.
EXPECT TIMING WILL BE SIMILAR TO THE CONVECTION THE PAST TWO NIGHTS.
BY SATURDAY NIGHT LOOKS LIKE ALTHOUGH THUNDERSTORMS OVER THE SIERRA
MADRE ARE POSSIBLE...THE MOVEMENT SHOULD BE QUITE DIFFERENT THAN
OTHER NIGHTS HAVE BEEN AND WILL BE. CORFIDI VECTORS AND THICKNESS
CONTOURS WOULD INDICATE AN ALMOST DUE SOUTH MOVEMENT SO HAVE OPTED
TO TAKE PRECIP WORDING OUT OF THE FORECAST FOR SATURDAY NIGHT.  COLD
FRONT STILL ON TRACK FOR MONDAY...WITH RATHER IMPRESSIVE MODEL
AGREEMENT FOR FOUR DAYS OUT. TIMING IS CLOSER TO THE SLOWER ECMWF
FROM YDAY RUNS AND HAVE STUCK MAINLY WITH THE ECMWF FOR THE FORECAST
THIS AFTERNOON. PRECIP CHANCES DO NOT LOOK GREAT AT THIS TIME...WITH
SLIGHT CHANCES IN THE EAST. BEHIND THE FRONT LOOK FOR A MODEST COOL
DOWN OF 5 TO 10 DEGREES FOR THE NEXT FEW DAYS WITH DRIER CONDITIONS
AND MOSTLY CLEAR SKIES.
