AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CORPUS CHRISTI TX
841 PM CDT TUE JUL 3 2007

.UPDATE...INFRARED AND WATER VAPOR IMAGERIES SHOWED LOW PRESSURE
CENTERED OVER CENTRAL TEXAS. CORPUS DOPPLER RADAR INDICATED
CONVECTION HAD ENDED ACROSS THE FORECAST AREA EXCEPT OVER THE
NORTHWEST CORNER WHERE A RAGGED LINE OF SHOWERS/THUNDERSTORMS WAS
MOVING INTO THE REGION FROM THE NORTHWEST. CLOUD TOPS ASSOCIATED
WITH THE ACTIVITY TO THE NORTHWEST HAD GENERALLY BEEN WARMING
EXCEPT ALONG AND NEAR A MORE SOLID LINE OF THUNDERSTORMS THAT HAD
PUSHED SOUTHWESTWARD INTO NORTHEAST MEXICO FROM THE HILL COUNTRY.
BEST CONVECTIVE POTENTIAL STILL REMAINS OVER THE WESTERN ZONES
THIS EVENING IN AREAS THAT HAD MUCH BETTER DAYTIME HEATING TODAY.
THE FEW THUNDERSTORMS THAT WERE MAKING IT INTO THE NORTHWEST
CORNER WERE NOT HOLDING TOGETHER WELL AS EFFECTS FROM DAYTIME
HEATING WERE DECREASING. THE AFOREMENTIONED LOW PRESSURE CENTER,
COUPLED WITH ABUNDANT MOISTURE ACROSS SOUTH TEXAS (00Z CORPUS
SOUNDING SHOWED 1.99 PWAT VALUE), ARGUES FOR THE CONINUATION OF
HIGH CHANCES OF PRECIPITATION OVERNIGHT, ESPECIALLY OUT WEST.
RAINFALL AMOUNTS WILL GENERALLY BE LESS THAN A QUARTER OF AN INCH
OVERNIGHT, THOUGH HIGHER AMOUNTS WILL EASILY BE POSSIBLE IN
PASSING THUNDERSTORMS. A FLASH FLOOD WATCH WITH EXCESSIVE RAINFALL
IS IN PLACE THROUGH MIDDAY WEDNESDAY WITH NO CHANGES ANTICIPATED
TO THIS PRODUCT AT THIS TIME. REMAINDER OF FORECASTS THIS EVENING
LOOK ON TRACK AS WELL, THUS NO CHANGES.

&&

.AVIATION...EXPECT CONVECTION AT KLRD TO MAINLY IMPACT AREA BETWEEN
01Z AND 05Z...BUT STILL COULD LINGER AFTER THAT SO HAVE A TEMPO
AFTER 05Z. FARTHER EAST...WILL PLAY A SIMILAR SCENARIO TO TODAY
WITH CONVECTION DEVELOPING OVERNIGHT THEN MOVING INLAND DURING THE
DAY...TIMING SIMILAR TO TODAY. ONLY CAVEAT IS HOW MUCH CONVECTION
OVER DEEP SOUTH TEXAS AFFECTS OVERALL AIRMASS...ATTM WITH UPPER LOW
STILL PROXIMATE FEELING IS NOT MUCH SINCE NOT MUCH LIFT AND
INSTABILITY NEEDED WITH ALL THE MOISTURE AVAILABLE TO GET CONVECTION
GOING ONCE AGAIN.  IF WINDS DIMINISH AND CLOUDS CLEAR OUT
ENOUGH...COULD AGAIN HAVE SOME BR ISSUES AT KALI.
