AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CORPUS CHRISTI TX
359 PM CDT THU MAY 21 2015

.SHORT TERM (TONIGHT THROUGH FRIDAY NIGHT)...ECMWF WAS THE ONLY
MODEL SUITE TO PROPERLY HANDLE THIS MORNING/S MCS DOWN THE RIO
GRANDE. EVEN TODAY/S 12Z GFS AND ASSOCIATED HI RESOLUTION MODEL
SUITES DID NOT PICK UP ON THIS MORNING/S EVENT. IN TURN THIS LEADS
TO LOWER FORECAST CONFIDENCE FOR THE SHORT TERM FORECAST PACKAGE.
AS OF WRITING...A COLD FRONT WAS LOCATED FROM NEAR PORT LAVACA TO
NEAR MATHIS TO SOUTH OF HEBBRONVILLE. CONVECTION ALONG THE FRONT
IS EXPECTED TO DIMINISH THIS EVENING AS DIURNALLY DRIVEN
INSTABILITY WANES. BRUSH COUNTRY REMAINS WORKED OVER FROM THIS
MORNING/S CONVECTION AND THUS AM NOT ANTICIPATING MUCH IN THE WAY
OF PRECIP THERE THIS EVENING. BIGGEST UNCERTAINTY OVERNIGHT IS
WHETHER OR NOT ADDITIONAL CONVECTION MOVES IN FROM OLD MX
OVERNIGHT. ECMWF AND GFS DIFFER SIGNIFICANTLY ON HANDLING OF H5
S/W TROUGHS PUSHING THROUGH. 12Z ECMWF ADVECTS A S/W TROUGH
THROUGH OVERNIGHT AND KEEPS MOST OF THE AREA DRY THROUGH THE NIGHT
WITH CONVECTION WEAKENING BEFORE REACHING THE CWA /ASIDE FROM
EARLY EVENING CONVECTION ACROSS THE EAST/. THE GFS ON THE
OTHERHAND BRINGS A MUCH MORE POTENT S/W TROUGH THROUGH OVERNIGHT
AND INITIATES DEEP CONVECTION ACROSS COAHUILA MX AND INTO THE
BRUSH COUNTRY TOWARDS SUNRISE. OVERALL...HAVE UNDERCUT MET/MAV
GUIDANCE FOR THE OVERNIGHT HOURS AND HAVE 30/40 POPS FROM EAST TO
WEST. OTHER THAN PRECIP POSSIBLY MOVING IN FROM THE WEST LATE IN
THE NIGHT...ADDITIONAL CONVECTION MAY DEVELOP ACROSS THE EAST
ALONG THE FRONT AFTER MIDNIGHT. FRONT IS PROG TO GRADUALLY SHIFT
BACK NORTH ON FRIDAY RESULTING IN AN UNSTABLE AIRMASS ACROSS THE
REGION. ASSUMING THAT THERE IS NOT ANOTHER MCS TRAVERSING THE AREA
IN THE MORNING...DIURNALLY DRIVEN CONVECTION SHOULD DEVELOP DURING
THE DAY. LOCALLY HEAVY RAINFALL WILL BE POSSIBLE WITH ANY
CONVECTION THAT DEVELOPS THROUGH THE PERIOD. SLIGHTLY COOLER TEMPS
TONIGHT GIVEN LIGHT NORTHERLY WINDS BEHIND THE FRONT WITH CLOUD
COVER/RAIN IMPACTING MAX TEMPS ON FRI.

&&

.LONG TERM...UNSETTLED WEATHER WILL CONTINUE INTO THE LONG TERM
PART OF THE FORECAST. UPPER LEVEL RIDGE AXIS WILL SLOWLY MOVE OFF
TO THE EAST AS STRONG UPPER TROUGH DIGS OVER THE WESTERN CONUS
INTO FOUR CORNERS REGION. PERIOD WILL BEGIN WITH PLENTY OF
MOISTURE ACROSS SOUTH TEXAS WITH PWAT VALUES AROUND 1.7 TO 1.8
INCHES. EMBEDDED DISTURBANCE IN SW FLOW ALOFT WILL MOVE ACROSS THE
AREA ON SATURDAY WITH 30 POPS IN THE MORNING THEN SLIGHTLY
INCREASING TO ACROSS THE NW IN THE AFTERNOON. MODELS CONTINUE TO
HINT AT ANOTHER MCS TO OUR NW IN SATURDAY NIGHT INTO SUNDAY
MORNING. FOCUS AGAIN WOULD SHIFT TO THE WESTERN PARTS ON THE
REGION INTO THE RIO GRANDE PLAINS WITH THIS ACTIVITY. DEEP LEVEL
TROUGH WILL SLOWLY APPROACH SUNDAY WITH INCREASING DIFLUENCE ALOFT
AND LARGE SCALE LIFT. POTENTIAL EXISTS FOR ANOTHER ROUND OF HEAVY
RAINFALL AND POSSIBLY SOME STRONG CONVECTION DURING THIS TIME.
THREAT WILL CONTINUE INTO MONDAY...MOST LIKELY ACROSS THE EASTERN
PART OF THE FORECAST AREA. SEVERAL INCHES OF RAINFALL WILL BE
LIKELY THIS WEEKEND INTO EARLY NEXT WEEK...AND A FLASH FLOOD WATCH
MAY BECOME NECESSARY FOR PARTS OR ALL OF SOUTH TEXAS. MAIN TROUGH
AXIS WILL SLOWLY MOVE EAST OF THE REGION BY TUESDAY...BUT
LINGERING MOISTURE AND INSTABILITY WILL RESULT IN AT LEAST
ISOLATED TO SCATTERED CONVECTION. TEMPERATURES THROUGH THE
EXTENDED WILL BE HIGHLY DEPENDENT ON RAINFALL AND CLOUD
COVER...BUT WILL GENERALLY BE IN THE 80S.
