AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CORPUS CHRISTI TX
833 PM CDT FRI MAY 10 2013

.DISCUSSION...SEVERE THUNDERSTORM WATCH HAS BEEN ISSUED FOR ALL OF
SOUTH TEXAS UNTIL 2 AM. TWO AREAS OF CONCERN...FIRST BEING LONG
TRACK SUPERCELL THAT HAS MOVED OUT OF ATASCOSA COUNTY AND INTO
MCMULLEN AND LIVE OAK COUNTIES...WITH HISTORY OF PRODUCING LARGE
HAIL. UNSTABLE ATMOSPHERE CONTINUES ACROSS THE CENTRAL AND NORTHERN
COUNTIES AND THIS STORM SHOULD CONTINUE TO TRACK SOUTHEAST THROUGH
THE NEXT HOUR OR TWO. ATMOSPHERE BECOMES MORE CAPPED NEAR THE
COAST...BUT SHOULD COLD POOL/OUTFLOW BOUNDARY BECOME BETTER
ESTABLISHED THERE IS THE CHANCE STORMS COULD REACH THE COAST.
FARTHER WEST...UPPER LEVEL SUPPORT IS NOW REACHING COAHUILA AND
THE RIO GRANDE...AND HAVE SEEN INCREASING DEVELOPMENT OF STORMS
ACROSS MEXICO. SOME OF THESE STORMS COULD WORK INTO THE RIO GRANDE
PLAINS AND BRUSH COUNTRY.

&&

.PREV DISCUSSION... /ISSUED 630 PM CDT FRI MAY 10 2013/

DISCUSSION...UPDATED FOR 00Z TAFS.

AVIATION...ACTIVE WEATHER EXPECTED TONIGHT AND TOMORROW ACROSS
THE TAF SITES. THUNDERSTORMS ARE EXPECTED TO DEVELOP AROUND THE
LRD SITE BETWEEN 01Z AND 03Z...THEN EXPAND AND MOVE EASTWARD
ACROSS THE REST OF SOUTH TEXAS THROUGH THE OVERNIGHT. A PERIOD OF
SEVERE STORMS IS POSSIBLE AT THE ONSET OF CONVECTION...THEN RAIN
WILL BE POSSIBLE THROUGH THE DAY TOMORROW. MVFR TO IFR CIGS ARE
EXPECTED THOUGH TOMORROW MORNING...BUT SHOULD IMPROVE IN THE
AFTERNOON.

PREV DISCUSSION... /ISSUED 337 PM CDT FRI MAY 10 2013/

SHORT TERM (TONIGHT THROUGH SATURDAY NIGHT)...IT WILL TAKE SOME
TIME FOR MOISTURE/INSTABILITY TO RECOVER OVER SOUTH TEXAS IN THE
WAKE OF THE OUTFLOW BOUNDARY. BUT IT DOES APPEAR TO BE OCCURRING
AS WINDS HAVE VEERED TO EASTERLY AND DEWPOINTS HAVE INCHED BACK
UP AROUND 70 DEGREES ALONG THE COAST. LAPS/SPC ANALYSIS SHOWS
INSTABILITY BUILDING ALONG THE RIO GRANDE BACK INTO THE HIGHER
TERRAIN IN NORTHERN MEXICO. STILL HAVING TO DEAL WITH CAPPING
INVERSION OVER THE AREA BUT MODELS SHOW THE CAP ERODING AS AN
IMPULSE IN THE SOUTHWEST FLOW ALOFT COMES OUT OF COAHUILA TONIGHT.
MODELS CONTINUE TO FORECAST INCREASING UPPER LEVEL DIVERGENCE OVER
SOUTH TEXAS LATER TONIGHT IN THE LEFT EXIT REGION OF 100 KNOT 25H
JET STREAK COMING OUT OF COAHUILA. THE RAPID REFRESH MODEL HAS
HAD THE BEST HANDLE ON CONVECTION EARLIER TODAY AND CURRENT
ACTIVITY DEVELOPING OVER THE EDWARDS PLATEAU INTO COAHUILA. LOW
LEVEL EASTERLY FLOW SHOULD MAINTAIN STORMS OVER NORTHEAST MEXICO
INTO THE BRUSH COUNTRY LATER THIS EVENING WITH THE POSSIBILITY OF
STORMS STEADILY MOVING EAST AS THE CAP WEAKENS OVER THE COASTAL
PLAINS. 0-6 KM SHEAR WILL REMAIN AT 50-60 KNOTS ACROSS SOUTH TEXAS
WITH ADEQUATE INSTABILITY TO KEEP A THREAT OF SEVERE STORMS IN THE
FORECAST FOR TONIGHT.

THE FRONT WILL MOVE THROUGH THE AREA LATE TONIGHT BUT ENOUGH
MOISTURE WILL REMAIN OVER THE REGION AS ANOTHER SHORT WAVE TROUGH
AND JET STREAK ENTER SOUTH TEXAS FROM THE SOUTHWEST SATURDAY. WILL
KEEP LIKELY POPS GOING FOR THE COASTAL PLAINS INTO THE COASTAL
WATERS FOR SATURDAY. THE UPPER LOW WILL BECOME DETACHED FROM THE
NORTHERN STREAM AS AN UPPER TROUGH SWINGS THROUGH OHIO RIVER
VALLEY SATURDAY NIGHT. THIS WILL BRING IN SOME DRIER AIR FROM THE
NORTH-NORTHEAST INTO THE SOUTH TEXAS WITH DIMINISHING RAIN CHANCES
FOR VICTORIA AREA. THE MOISTURE AXIS WILL REMAIN ALONG THE RIO
GRANDE KEEPING A THREAT FOR SCATTERED CONVECTION SATURDAY NIGHT.

LONG TERM (SUNDAY THROUGH FRIDAY)...EXTENDED PERIOD BEGINS WITH
MODELS IN SOME DISARRAY AS THEY STRUGGLE TO HANDLE MOISTURE POOLING
BEHIND THE COLD FRONT MOVING THROUGH OVER THE WEEKEND. CURRENT
THINKING IS THAT MOISTURE POOLING ALONG THE RIO GRANDE COULD COMBINE
WITH WEAK UPSLOPE FLOW TO TRIGGER ISOLATED CONVECTION OUT WEST
SUNDAY AND SUNDAY NIGHT.

THIS SCENARIO EXTENDS INTO MONDAY AND TUESDAY AS A SURFACE HIGH
BUILDS INTO THE CENTRAL GULF COAST AND ADDITIONAL MOISTURE WRAPS
AROUND THE HIGH ON GENERALLY EASTERLY MARINE FLOW. UPPER SUPPORT
REMAINS NEUTRAL TO SLIGHTLY POSITIVE AS MODELS MAINTAIN AN UPPER LOW
OVER BAJA CALIFORNIA AND ROTATE WEAK RIPPLES THROUGH THAT FLOW. HAVE
LEFT IN LOW CHANCE POPS THROUGH TUESDAY NIGHT TO HANDLE THIS
POSSIBILITY. BY WEDNESDAY THE UPPER SUPPORT FINALLY LIFTS OUT AND
GULF MOISTURE CONDUIT BREAKS DOWN...SO EXPECT DRY WEATHER FROM THERE
ON OUT WITH WARMING TEMPERATURES AS GENERALLY UNSETTLED PERIOD ENDS.

EXPECT TEMPERATURES TO STAY BELOW NORMALS THROUGH THE FIRST PART OF
NEXT WEEK ANTICIPATING HIGHER THEN NORMAL CLOUD COVER AND HUMIDITY
LEVELS. HEIGHTS AND TEMPERATURES LOOK TO INCREASE SUBSTANTIALLY
TOWARD THE END OF THE PERIOD.
