AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CORPUS CHRISTI TX
305 PM CDT THU JUL 22 2004

.SHORT-TERM (TONIGHT THROUGH FRIDAY NIGHT)...DIURNAL CONVECTION
FIRING UP AGAIN TODAY ALONG AND AHEAD OF THE SEA-BREEZE FRONT.
EXPECT THIS ACTIVITY TO MOVE NORTH AND WEST INTO THE RIO GRANDE
PLAINS LATER THIS AFTERNOON.  DO NOT EXPECT ANYTHING SEVERE BUT WITH
THE DRY AIR IN THE MID-LEVELS...CANNOT RULE OUT AN ISOLATED STRONG
STORM.  UPPER-LEVEL LOW CONTINUES WEST-NORTHWEST TRACK INTO THE BIG
BEND COUNTRY.  SHOULD SEE THE CONVECTION WANE AS THE DAYTIME HEATING
DIMINISHES THIS EVENING...BUT COULD STILL SEE A FEW LINGERING TSRA.
MAY NEED A PRE-PERIOD ON THE AFTERNOON ZONES TO ACCOUNT FOR ONGOING
CONVECTION THAT WILL NOT BE COVERED BY THE EVENING PERIOD.  NOT
EXPECTING MUCH IN THE WAY OF FOG TONIGHT...ALTHOUGH COULD SEE
LOCATIONS ALONG THE HIGHWAY 77 CORRIDOR EXPERIENCE PATCHY FOG FOR A
BRIEF TIME.  TOMORROW...SHOULD SEE SCATTERED TSRA OVER THE
NORTHEASTERN AREAS...AND ADJACENT COASTAL WATERS...DURING THE
MORNING HOURS.  THIS SHOULD GIVE WAY TO SCATTERED ACTIVITY ALONG THE
SEA-BREEZE DURING THE AFTERNOON.  MODELS ARE SHOWING H25 WINDS
BECOMING INCREASINGLY DIFFLUENT OVER THE NEXT 12-24 HOURS AS THE
UPPER-LOW MOVES WEST.  THIS COMBINED WITH MODEST MOISTURE AND
SEA-BREEZE WILL ALLOW TSRA TO DEVELOP.  AGAIN...THIS SHOULD DIMINISH
DURING THE EVENING HOURS TOMORROW.  SCEC CONTINUES FOR THE SOUTHERN
BAYS THIS EVENING...BUT WILL LIKELY BE DROPPED WITH THE 1030PM
PACKAGE. MAY NEED TO PUT SCEC OUT FOR THE GULF WATERS FOR THE
OVERNIGHT PERIOD FOR WINDS 15 TO 20 KNOTS.

&&

.LONG-TERM (SATURDAY THROUGH THURSDAY)...EXTENDED PORTION OF THE
FORECAST REMAINS A CHALLENGE AS MODELS STILL DIFFER ON HANDLING OF
THE FRONTAL BOUNDARY SUNDAY THROUGH TUESDAY.  GFS HAS BEEN
FLIP-FLOPPING ON ITS SOLUTION...BEING MORE AGGRESSIVE WITH THE FRONT
WHILE CANADIAN AND NOGAPS PRETTY MUCH KEEP IT NORTH OF THE AREA.
GENERALLY EXPECT THE FRONT TO STAY TO THE NORTH...ALTHOUGH WE COULD
GET SOME LIGHT NORTH WINDS IN THE MORNING OVER THE NORTHEASTERN
COUNTIES.  AVAILABLE MODELS SHOWING ATMOSPHERIC HUMIDITY HAVE BEEN
PERSISTENT/SOMEWHAT CONSISTENT IN BRINGING HIGHER MOISTURE VALUES
INTO THE AREA BY TUESDAY MORNING...WITH GFS HAVING 2 INCH PWATS OVER
THE AREA BY THEN.  AGAIN...MOISTURE MAY BE A BIT OVERDONE BY THE GFS
BRINGING THE BOUNDARY DOWN SO FAR TO THE SOUTH...HOWEVER GIVEN THE
THE OFTEN DRIER DGEXU HAS BEEN SHOWING THIS BETTER MOISTURE OVER THE
AREA AND THE EXPECTED WIND FIELDS ARE LIGHT IN A COL AREA
ALOFT...WITH GO WITH CHANCE POPS MONDAY...TUESDAY AND WEDNESDAY OVER
THE EAST AND SLIGHT CHANCE OVER THE WEST.  UPPER HIGH TRYING TO
BUILD BACK ON THURSDAY AND MOISTURE IS A BIT MORE LACKING...AND
WINDS BEGINNING TO PICK UP A BIT.  AS A RESULT...WILL JUST GO WITH
SLIGHT CHANCE POPS OVER THE EAST ON THURSDAY.  AS FAR AS
TEMPERATURES ARE CONCERNED...WILL KEEP MAX TEMPS ABOVE CLIMATOLOGY
SATURDAY AND SUNDAY...BUT KEEP THEM NEAR TO BELOW CLIMO MONDAY
THROUGH WEDNESDAY WITH THE INCREASE IN CLOUD COVER AND THE CHANCE
FOR PRECIPITATION.  WILL GO WITH NEAR CLIMATOLOGY WITH MIN
TEMPERATURES FOR MOST PERIODS.  WINDS WILL NOT BE TOO STRONG UNTIL
THE END OF THE FORECAST PERIOD AS THE THERMAL LOW REDEVELOPS OVER
THE LEE OF THE ROCKIES.
