AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE CORPUS CHRISTI TX
1149 PM CST WED FEB 25 2009

.DISCUSSION...SEE AVIATION DISCUSSION BELOW.

&&

.AVIATION...MOISTURE TRAPPED BENEATH A STRONG INVERSION WILL
CONTINUE TO GENERATE MVFR CIGS ACROSS SOUTH TEXAS THROUGH THE
OVERNIGHT HOURS. MVFR/TEMPO IFR CIGS INLAND AFTER SUNRISE WILL
GRADUALLY SCT OUT TO VFR BETWEEN 15Z-16Z ACROSS THE SOUTHERN
PORTIONS OF THE REGION. BKN VFR CIGS ARE ANTICIPATED ALL DAY
THURSDAY FOR KVCT. WINDS WILL ONCE AGAIN BE GUSTY FOR THE COASTAL
PLAINS WITH WIND GUSTS RANGING BETWEEN 20-30 KNOTS BY THURSDAY
AFTERNOON. ANOTHER ROUND OF MVFR CIGS ARE EXPECTED TO DEVELOP
ACROSS SOUTH TEXAS BEFORE MIDNIGHT THURSDAY NIGHT.

&&

.PREV DISCUSSION... /ISSUED 938 PM CST WED FEB 25 2009/

DISCUSSION...11-3.9 MICRON SATELLITE IMAGERY SHOWS STRATUS ACROSS
THE EASTERN CWA GRADUALLY SPREADING INLAND THROUGH THE EVENING
HOURS. EXPECT THIS TREND TO CONTINUE OVERNIGHT WITH MOSTLY CLOUDY
SKIES AREAWIDE BY SUNRISE. ONLY UPDATED THE GRIDS TO ACCOUNT FOR
CURRENT TEMP/DEWPOINT OBS/TRENDS. OTHERWISE...THE CURRENT FORECAST
IS IN GOOD SHAPE. NO UPDATES ARE REQUIRED TO THE TEXT PRODUCTS.

PREV DISCUSSION... /ISSUED 252 PM CST WED FEB 25 2009/

SHORT TERM (TONIGHT THROUGH THURSDAY NIGHT)...A DEEP NW FLOW ALOFT
WILL MAINTAIN DRY WARM CONDITIONS ACROSS S TX THROUGH THE SHORT
TERM. DEEPENING LOW PRESSURE SYSTEM ACROSS THE PLAINS WILL CONT TO
STRENGTHEN THE SFC AND LOW LEVEL SLY WINDS THRU THU...WITH
BREEZY/WINDY CONDITIONS EXPECTED ONCE AGAIN THU AFTERNOON. WIND
SPEEDS ARE EXPECTED TO BE A COUPLE OF KNOTS HIGHER THAN THIS
AFTERNOON BUT ARE EXPECTED TO REMAIN BELOW WIND ADVISORY CRITERIA.
THE STRONG LOW LEVEL JET TONIGHT WILL PRODUCE A STRATUS DECK WHICH
WILL INHIBIT FOG FORMATION. LIGHT PATCHY FOG IS ALL THAT IS
EXPECTED. SIMILAR CONDITIONS ARE EXPECTED THU NITE. MN AND MX TEMPS
WILL CONT TO BE ABV NORM WITH MX TEMPS IN THE 90S ACROSS THE W HALF
OF THE CWA.

MARINE (TONIGHT THROUGH THURSDAY NIGHT)...A MOD TO STRONG ONSHORE
FLOW WILL PREVAIL THRU THE SHORT TERM. STRONG WINDS OVER THE SRN
BAYS THIS AFTERNOON WILL SHIFT OFFSHORE OVR NITE DUE TO DIURNAL
COOLING OVR LAND AREAS AND A STRENGTHENING LOW LEVEL JET ACROSS THE
WATERS. WINDS WILL BE 2 TO 4 KNOTS HIGHER THU AFTERNOON ACROSS THE
BAYS THEN SPREADING ONCE AGAIN OVER THE COASTAL WATERS THU NITE.
THEREFORE SCA CONDITIONS ARE EXPECTED TO BE ACROSS BAYS DURING THE
AFTERNOONS...ESPECIALLY SRN BAYS...AND OFFSHORE DURING THE NIGHTS.
WINDS ACROSS THE NEAR SHORE ARE LESS LIKELY TO REACH SCA CONDITIONS
DUE TO THE COOLER SHELF WATERS BUT MAY BE BORDERLINE THU NITE.

FIRE WEATHER (TONIGHT THROUGH THURSDAY NIGHT)...ELEVATED FIRE
DANGER CAN BE EXPECTED ONCE AGAIN THU AFTERNOON DUE TO VERY DRY
FUELS AND STRONG GUSTY WINDS. HOWEVER...RH VALUES ARE EXPECTED TO BE
HIGH ENOUGH THAT RED FLAG CONDITIONS ARE NOT ANTICIPATED FOR THU.

LONG TERM (FRIDAY THROUGH WEDNESDAY)...THE PERIOD WILL BEGIN WITH
THE LAST OF A SERIES OF VERY WARM DAYS THE END THE WEEK AS S-SW LOW
LEVEL FLOW PERSISTS AND A PREFRONTAL TROUGH MOVES INTO THE REGION.
MODELS SHOW DIFFERING SOLNS WRT ARRIVAL OF THE NEXT FRONT BUT ALL
INDICATE SOME TIME ON SAT. WILL CONTINUE TO LEAN TOWARD MORE OF AN
AFTN ARRIVAL ALTHOUGH THERE IS SOME INDICATION OF AN EARLIER WEAK
INITIAL BOUNDARY. STILL LOOKS VERY DRY ADVANCE OF THE FRONT AND
PRECIP POTENTIAL IS VERY LIMITED (POPS AOB 10%). MOST RECENT MODELS
HAVE BACKED OFF SLIGHTLY WRT STRENGTH OF THE FRONT...BUT WILL
CONTINUE TO LEAN BELOW MOS FOR LOWS GIVEN VERY DRY AIRMASS. A
MARGINAL RED FLAG EVENT MAY BE POSSIBLE POST FRONT MAINLY ON
SUN...BUT LOOKS LIKE WINDS WILL HAVE DROPPED OFF AND LOW RH VALUES
WILL BE ONLY CONCERN. QUICK RECOVERY AND RETURN TO ONSHORE FLOW ON
TAP FOR MON DUE TO MID LEVEL RIDGING AND QUICK SHIFT OF HIGH
PRESSURE TO THE EAST AND LOOKS LIKE THE RETURN TO WELL ABOVE NORMAL
TEMPS THE LAST FEW DAYS OF THE FORECAST PERIOD.
