AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CORPUS CHRISTI TX
747 PM CDT SUN SEP 23 2012

.DISCUSSION...MORE TSRA ACTIVITY OCCURRED THIS EVENING THAN WAS
EXPECTED DUE TO DEEPER MOISTURE ADVECTING FARTHER N INTO THE NRN
RIO GRANDE PLAINS. THE ACTIVITY IS BEGINNING TO DIMINISH ACROSS
WEBB COUNTY AND IS EXPECTED TO DIMINISH ACROSS LASALLE AS WELL
WITHIN THE HOUR. WILL UPDATE ZONES TO REMOVE THE MENTION OF
EVENING SHRA/TSRA'S FROM WESTERN ZONES AND WILL INCREASE SKY COVER.
REST OF FCST LOOKS ON TRACK WITH NO OTHER CHANGES ANTICIPATED AT
THIS TIME.

&&

.PREV DISCUSSION... /ISSUED 708 PM CDT SUN SEP 23 2012/

DISCUSSION...SEE AVIATION BELOW FOR UPDATES

AVIATION...START PERIOD WITH VCSH AT KLRD...AND VFR CONDITIONS AT
KALI...KCRP...AND KVCT. EXPECT ACTIVITY TO MOVE OUT FROM KLRD BY
01Z THIS EVENING. MAIN CONCERN FOR THE PERIOD WILL BE DEVELOPMENT
OF PATCHY FOG ACROSS KALI...KCRP...AND KVCT OVERNIGHT AND INTO THE
EARLY MORNING. VISIBILITIES WILL BE REDUCED TO 1/2 MILE AT
TIMES...WITH CONDITIONS MOVING BETWEEN MVFR-IFR-LIFR. EXPECT BR/FG
TO DIMINISH WITH SUNRISE...AND CEILING TO RISE THROUGH THE DAY.
WINDS WILL REMAIN GENERALLY LIGHT OUT OF THE SOUTHEAST THROUGH
MOST OF THE PERIOD.

PREV DISCUSSION... /ISSUED 500 PM CDT SUN SEP 23 2012/

DISCUSSION...MADE MINOR UPDATE TO WEATHER FCST ACROSS THE
SOUTHERN BRUSH COUNTRY/RIO GRANDE PLAINS BY INCLUDING THE MENTION
OF ISOLD SHRA/TSRA FOR THIS EVENING. RADAR WAS INDICATING
CONVECTION ACROSS THE S PORTIONS OF DUVAL COUNTY THAT IS MOVG
GENERALLY WEST INTO A LESS FAVORABLE ENVIRONMENT...BUT STILL
SLIGHTLY UNSTABLE. THIS SHOULD BE SHORT-LIVED ONCE THE SUN GOES
DOWN AND THE ATMOSPHERE STABILIZES.

PREV DISCUSSION... /ISSUED 259 PM CDT SUN SEP 23 2012/

SHORT TERM (TONIGHT THROUGH MONDAY NIGHT)...GENERALLY QUIET WX
EXPECTED THROUGH THE SHORT TERM PERIOD. SEA BREEZE IS PUSHING
INLAND AS OF WRITING WITH ISOLATED CONVECTION DEVELOPING OVER S
CNTRL ZONES. ACTIVITY SHOULD QUICKLY DIMINISH LATE THIS AFTERNOON
WITH LOSS OF DIURNAL HEATING. MODERATE SERLY LLJ PROG TO DEVELOP
OVERNIGHT ALONG RIO GRANDE IN RESPONSE TO WEAK LOW PRESSURE OVER
THE PLAINS. THIS SHOULD AID IN SCATTERED STRATUS DEVELOPMENT OVER
WESTERN ZONES LATE TONIGHT AND INTO MONDAY MORNING. FARTHER
EAST...COMBINATION OF LIGHT WINDS...MOIST AIRMASS IN THE LOWER
LEVELS WITH DRY AIR JUST ABOVE MOIST LAYER SHOULD LEAD TO THE
DEVELOPMENT OF PATCHY FOG ALONG AND WEST OF HIGHWAY 77 FROM LATE
TONIGHT SHORTLY AFTER SUNRISE MONDAY. ANY FOG THAT OCCURS SHOULD
MIX OUT BY MID MORNING WITH MOSTLY SUNNY SKIES PREVAILING THROUGH
THE DAY AREAWIDE AS AREA TO BE IN SUBSIDENT AIRMASS. A STRONGER
LOW LEVEL JET MON NIGHT SHOULD ALLOW SURFACE WINDS TO REMAIN A
LITTLE MORE ELEVATED THROUGH THE NIGHT ALONG WITH MORE CLOUD COVER
THAN PREVIOUS NIGHTS. WENT CLOSE TO GUIDANCE FOR MIN TEMPS
TONIGHT AND A LITTLE ABOVE FOR MON NIGHT AS CLOUD COVER AND
ELEVATED SURFACE WINDS SHOULD PREVENT TEMPS FROM FALLING MUCH PAST
THE LOW TO MID 70S. HAVE GONE ABOVE GUIDANCE ALL BUT COASTAL AREAS
ON MONDAY AS SUBSIDENT AIRMASS AND MORE SERLY WIND PROFILE SHOULD
AID IN HIGHS REACHING THE MID 90S /LOW 90S NE ZONES/.

LONG TERM (TUESDAY THROUGH SATURDAY)...SHORTWAVE TROUGH WILL BE
MOVING OUT OF THE FOUR CORNERS REGION...SHIFTING RIDGE AXIS EAST
OF THE AREA. AT THE SURFACE...LEE SIDE TROUGH WILL SETUP OVER WEST
TEXAS...STRENGTHENING THE PRESSURE GRADIENT OVER THE AREA. WINDS
WILL PICK UP ON TUESDAY INTO THE BREEZY CATEGORY WHICH COULD
CREATE SOME AREAS OF ELEVATED FIRE WEATHER ACROSS THE BRUSH
COUNTRY AND RIO GRANDE PLAINS. SHORTWAVE WILL WEAKEN AS IT EMERGES
ONTO THE PLAINS...WITH LOWER WINDS EXPECTED FOR WEDNESDAY AND
THURSDAY. LOW PW/S WILL BE SITUATED ACROSS SOUTH TEXAS TO BEGIN
THE LONG TERM... BUT PERSISTENT SOUTHEASTERLY FLOW WILL USHER
MOISTURE BACK INTO THE REGION. GFS PROGS PW/S TO INCREASE TO
AROUND 1.7/1.8 INCHES BY THURSDAY AFTERNOON...CLIMBING AT OR ABOVE
2 INCHES FROM FRIDAY INTO SATURDAY. WITH THE INCREASE IN
MOISTURE...BELIEVE CHANCES FOR ISOLATED SHOWERS AND STORMS WILL BE
BETTER LATE IN THE WEEK. HOWEVER...MODELS DO DIVERGE IN HANDLING
TROPICAL SYSTEM MIRIAM IN THE PACIFIC AND ITS EVENTUAL TRACK.
ALSO...TOWARDS THE VERY END OF THE FORECAST THE EUROPEAN WANTS TO
BRING A FRONT THROUGH WHILE THE GFS KEEPS DEEPER MOISTURE AROUND
THE AREA. FOR NOW...HAVE LEFT THE 20 AND 30 POPS IN THE FORECAST
FROM THURSDAY THROUGH SATURDAY...WHICH IS IN DECENT AGREEMENT WITH
12Z MEX POPS.
