AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE CORPUS CHRISTI TX
1224 PM CDT SAT AUG 1 2009
.DISCUSSION...SEE AVIATION SECTION.
&&
.AVIATION...WITH DRIER AIR MOVING INTO SOUTH TEXAS...EXPECT
VFR CONDITIONS WILL BE PREVALENT OVER THE AREA THROUGH SUNDAY
MORNING. MODELS INDICATED THE MOIST LAYER AROUND 2 KFT...EVIDENT
ON THE 12Z CRP SOUNDING...WILL BE DRIER SUNDAY MORNING. SO DO NOT
EXPECT TO SEE MORE THAN VERY ISOLATED PATCHES OF MVFR CEILINGS
OVER THE INLAND COASTAL PLAINS OVERNIGHT. SOUTH WINDS DURING THE
OVERNIGHT AND MORNING HOURS WILL BECOME GUSTY BY MID MORNING AND
SHIFT TO SOUTHEAST AS THE SEA BREEZE FORMS IN THE AFTERNOON.
&&
.PREV DISCUSSION... /ISSUED 1057 AM CDT SAT AUG 1 2009/
DISCUSSION...LOOP OF GOES SOUNDER IMAGER OF PRECIPITABLE WATER
SHOWS THE MUCH DRIER AIR OVER THE GULF OF MEXICO ADVECTING TO THE
NORTHWEST INTO SOUTH TEXAS. 12Z CRP SOUNDING HAD A PWAT VALUE OF
0.89 INCHES COMPARED TO NEARLY 2 INCHES YESTERDAY MORNING. HOT AND
DRY WILL START AUGUST...WITH TEMPERATURES LIKELY TO A BE A FEW
DEGREES BELOW RECORDS AT CRP AND VCT TODAY. BREEZY/WINDY CONDITIONS
WILL CONTINUE TODAY AS WELL AS STRONG THERMAL GRADIENT DEVELOPS BY
THIS AFTERNOON. TEMPERATURE FORECAST LOOKS ON TRACK AND MADE NO
CHANGES TO CURRENT HEAT ADVISORY CONFIGURATION.
MARINE...OBSERVATIONS OVER THE NORTHERN BAYS SHOW WINDS SPEEDS
ABOUT 5 MPH HIGHER THAN THIS TIME YESTERDAY. 12Z CRP SOUNDING SHOWED
A 30-35 KNOT LOW LEVEL JET OVER THE REGION THIS MORNING. WENT AHEAD
AND INCLUDED THE NORTHERN BAYS IN THE SCA FOR THIS AFTERNOON INTO
THIS EVENING. THERMAL GRADIENT WILL STRENGTHEN OVER THE SOUTHERN
COASTAL BEND THIS AFTERNOON AND EXPECT WINDS WILL BE NEAR SCA FOR
THE NEARSHORE WATERS BY THEN. GFS/NAM MODELS SHOW 30 KNOT LOW LEVEL
FLOW OVER THE NEARSHORE WATERS THROUGH 06Z...SO EXTENDED THE SCA
FOR THIS AREA UNTIL AT LEAST 07Z SUNDAY.
PREV DISCUSSION... /ISSUED 337 AM CDT SAT AUG 1 2009/
SHORT TERM (TODAY THROUGH SUNDAY)...HEAT AND LACK OF RAIN REMAINS
THE STORY OVER SOUTH TEXAS AS ANOTHER MONTH BEGINS. THERE IS A
SMALL CHANCE FOR SOME SHOWERS/STORMS THIS AFTERNOON ALONG THE SEA
BREEZE OVER INLAND AREAS...BUT ACTIVITY EXPECTED BE ISOLATED.
ACTIVITY HAS THE POTENTIAL TO BE ENHANCED BY SOME WEAK SYNOPTIC
SCALE LIFT PROGGED BY THE DETERMINISTIC MODELS FOR TODAY. BEST
MOISTURE OVER THE EXTREME NORTHERN/NORTWESTERN AREAS BEGINS TO
LIFT NORTH THROUGH SUNDAY...ELIMINATING THE MEAGER CHANCE FOR RAIN
SOUTH TEXAS ALREADY HAS. DRY SOILS AND SUFFICIENT SUNSHINE WILL
KEEP TEMPERATURES WELL ABOVE NORMAL AGAIN. IT IS BORDERLINE...BUT
IT APPEARS THAT HEAT INDICES OVER THE SOUTHERN TIER OF COUNTIES
WILL BE NEAR 110 DEGREES OR MORE FOR TWO HOURS OR SO...THUS HAVE
GONE WITH HEAT ADVISORY FOR THIS AREA. NORTHERN AREAS WILL MAINLY
BE IN THE 105 TO 109 DEGREE RANGE FOR SOME PART OF THE AFTERNOON.
BREEZY CONDITIONS EXPECTED TODAY NEAR THE COAST AND SPREAD INLAND
TONIGHT AS WINDS REMAIN UP. THIS WILL MAKE ANOTHER NIGHT FOR
WARMER THAN NORMAL OVERNIGHT LOWS. OVERALL...GENERALLY STAYED ON
THE WARM SIDE OR WENT ABOVE GUIDANCE ALL THREE PERIODS.
MARINE (TONIGHT THROUGH SUNDAY)...SCA HAS BEEN ISSUED FOR
SOUTHERN BAYS. APPEARS SOUTHERN NEARSHORE WILL REMAIN BELOW SCA
AND OFFSHORE AROUND 15 KNOTS. SCA MAY HAVE TO BE EXTENDED OVER THE
NEARSHORE GULFMEX FOR TONIGHT...BUT WILL LET THE DAY SHIFT SEE IF
THAT IS NEEDED RATHER THAN ISSUE IT AND HAVE DAY SHIFT REMOVE IF
NOT APPLICABLE.
FIRE WEATHER...BREEZY CONDITIONS ALONG WITH MIN RH VALUES 30 TO
40 PERCENT INLAND AREAS AND 40 TO 50 PERCENT COASTAL COUNTIES WILL
MEAN ENHANCED FIRE DANGER TODAY...WILL ISSUE RFD FOR ALL BUT FOUR
WESTERN COUNTIES AS WINDS WILL REMAIN TOO LOW.
LONG TERM (SUNDAY NIGHT THROUGH FRIDAY)...AN UPPER LEVEL
ANTICYCLONE CENTERED OVER SOUTH TEXAS SUNDAY NIGHT WILL GRADUALLY
RETROGRADE INTO NORTHERN MEXICO BY WEDNESDAY...THEN SHIFT NORTHWARD
INTO THE FOUR CORNERS REGION OF THE DESERT SOUTHWEST. THE STRONG
MID/UPPER RIDGING WILL CONTINUE TO PRODUCE SYNOPTIC SUBSIDENCE
ACROSS THE REGION THROUGH THE PERIOD. AS A RESULT...HOT AND DRY
CONDITIONS ARE EXPECTED FOR ALL OF NEXT WEEK WITH HIGH TEMPERATURES
RANGING FROM THE LOW 90S ALONG THE COAST...TO AROUND 105 TO 107
DEGREES ALONG THE RIO GRANDE. HEAT INDEX VALUES EACH AFTERNOON WILL
LIKELY RANGE FROM 105 TO 109 DEGREES NORTH OF HIGHWAY 44...AND 110
TO 115 DEGREES SOUTH OF HIGHWAY 44.
