.AVIATION...LIGHT NORTHEAST TO EAST WINDS PREVAIL AT THE REGIONAL
AIRPORTS THIS MORNING UNDER MOSTLY CLEAR SKIES. ONLY SCT HIGH
DEBRIS CLOUDS ARE MOVING OVER FROM THE SOUTHWEST. SURFACE HIGH
PRESSURE WILL REMAIN DOMINANT THE NEXT 24 HOURS...BUT DEEPENING
LOW PRESSURE OVER THE SOUTHERN HIGH PLAINS WILL WORK TO TIGHTEN
THE LOCAL PRESSURE GRADIENT AND INCREASE WINDS TODAY. BREEZY
SOUTHEAST WINDS WILL BE ON TAP FOR THIS AFTERNOON...AND WILL IN
FACT CONTINUE INTO THIS EVENING AND TONIGHT. THE WINDS WILL BRING
BKN TO OVC LOW CLOUDS IN FROM THE GULF TONIGHT WITH MVFR CEILINGS.
A SLIGHT REDUCTION IN VISIBILITY DUE TO HAZE WILL BE POSSIBLE
BEFORE DAWN SATURDAY MORNING.

&&

.PREV DISCUSSION... /ISSUED 623 PM CDT THU APR 28 2011/

DISCUSSION...SEE UPDATED AVIATION SECTION FOR DISCUSSION ON THE
00Z TAF PACKAGE.

AVIATION...VFR FLIGHT CONDITIONS ARE EXPECTED TO PREVAIL THROUGH
THE NEXT 24 HOURS. CLEAR SKIES ARE BEING OBSERVED AT ALL TERMINALS
THIS AFTERNOON WITH EASTERLY WINDS REMAINING AROUND 10-15 KTS AND
GUSTY. WINDS SHOULD BEGIN TO LET UP OVERNIGHT TO DROP BELOW 10 KTS
FOR ALL TERMINALS. WINDS WILL AGAIN PICK UP AND BECOME GUSTY AFTER
SUNRISE FRIDAY HOWEVER. SKIES WILL REMAIN RATHER CLEAR THROUGH
MOST OF THE TAF PERIOD. A FEW CLOUDS MAY BEGIN TO RETURN TO THE
AREA FRIDAY AFTERNOON AND ESPECIALLY INTO FRIDAY EVENING.

PREV DISCUSSION... /ISSUED 236 PM CDT THU APR 28 2011/

SHORT TERM /TONIGHT THROUGH FRIDAY NIGHT/...NO CONCERNS WEATHER
WISE FOR DEEP SOUTH TX DURING THE SHORT TERM FORECAST PERIOD. HIGH
PRESSURE...CURRENTLY CENTERED OVER NORTH CENTRAL SECTIONS OF THE
STATE EARLY THIS AFTN...WILL CONTINUE TO DRIFT ESEWD THE REMAINDER
OF TODAY AND TONIGHT. THIS HIGH WILL BECOME SITUATED ACROSS THE
NORTHWEST GULF OF MEXICO AND THE LWR MS VALLEY DURING THE DAY
FRIDAY. OUR LOCAL LLVL FLOW WILL VEER WITH TIME AND BECOME SELY
TONIGHT AND FRIDAY. THE RESUMING ONSHORE FLOW WILL BEGIN TO
TRANSITION OUR CURRENT DRY AND COMFORTABLE AIRMASS INTO A MORE HUMID
AND INCREASINGLY UNCOMFORTABLE ONE BY THE END OF THE PERIOD. CLEAR
SKIES COMBINED WITH DRY SFC AIR TONIGHT WILL ALLOW TEMPS TO REACH
THE UPPER 50S NORTH AND TO MID 60S SOUTH AND EAST. PLENTY OF
SUNSHINE IS EXPECTED ONCE AGAIN ON FRIDAY WITH SLIGHTLY WARMER AFTN
TEMPERATURES IN THE UPPER 80S TO LOW 90S ACROSS OUR CENTRAL AND
EASTERN COS WITH MID 90S FAR WEST.

LONG TERM /SATURDAY THROUGH THURSDAY/...VERY WARM TO HOT
TEMPERATURES ARE EXPECTED TO DEVELOP SATURDAY AS LOW PRESSURE
ACROSS THE SOUTHERN PLAINS BRINGS A SURFACE TROUGH INTO SOUTHWEST
TX SAT AFTERNOON PROVIDING A MORE SOUTHERLY THAN SOUTHEAST WIND
ACROSS THE CWA. NOT VERY CONFIDENT ABOUT RAIN CHANCES DEVELOPING
SUNDAY INTO SUN NIGHT AS A COLD FRONT IS PROGGED TO BRING A LINE
OF CONVECTION ACROSS NORTH TX SUN MORNING SOUTHWARD INTO SOUTH TX
EARLY MONDAY. BUT WITH MOST OF THE LONG TERM MODELS BRINGING LOW
LEVEL MOISTURE ACROSS THE RIO GRANDE PLAINS FOR THE END OF THE
WEEKEND...WILL GO AHEAD AND MENTION A SLIGHT CHANCE OF SHOWERS
AND THUNDERSTORMS SUN NIGHT FOR NOW EVEN THOUGH THE PAST FRONTAL
SYSTEMS HAVE BEEN DRY AND THE SEVERE TO EXTREME DROUGHT CONDITIONS
ACROSS DEEP SOUTH TX PERSIST. THE GFS CONTINUES TO PROG RAIN
CHANCES INTO EARLY NEXT WEEK BUT THE ECMWF BRINGS DRIER AIR INTO
THE LOWER RIO GRANDE VALLEY IN THE WAKE OF THE FRONTAL PASSAGE MON
NIGHT INTO TUESDAY. WILL NOT MENTION ANY RAIN CHANCES THROUGH THE
REST OF THE FORECAST PERIOD FOR NOW EXCEPT FOR WEDNESDAY WHERE
BOTH THE GFS AND ECMWF PROG MOISTURE INCREASING ACROSS THE AREA
WITH AN ONSHORE FLOW RETURNING TOWARDS THE MIDDLE OF NEXT WEEK. &&

MARINE...
TONIGHT THROUGH FRIDAY NIGHT...THE 1 PM OBSERVATION FROM
BUOY020 INDICATED WINDS WERE NORTHEAST AROUND 14 KTS GUSTING TO
AROUND 16 KTS AND SEAS WERE AROUND 9 FT WITH A PERIOD OF 8 SECONDS.
MARINE CONDITIONS WILL CONTINUE TO REMAIN UNSETTLED ACROSS THE GULF
OF MEXICO WATERS THE REMAINDER OF THE AFTN INTO EARLY
EVENING...MAINLY DUE TO THE ROUGH SEAS. HOWEVER...AN IMPROVING TREND
IS EXPECTED WITH TIME BY THIS EVENING AS SEAS SLOWLY SUBSIDE. THE
STRONGER NELY WINDS HAVE DIMINISHED THIS AFTN FROM EARLIER MAXES AND
ARE EXPECTED TO CONTINUE TO DIMINISH THE REMAINDER OF THE DAY. HIGH
PRESSURE BUILDING INTO THE NW GULF AND CLOSER TO OUR LOCAL MARINE
AREA WILL ALLOW MORE FAVORABLE MARINE CONDITIONS TO PREVAIL TONIGHT
INTO FRIDAY. A VEERING LOW LEVEL FLOW TONIGHT WILL MEAN SELY WINDS
WILL RETURN OVRNGT AND FRIDAY. THE ONSHORE FLOW IS EXPECTED TO
STRENGTHEN A BIT BY THE AFTN AND THE END OF THE PERIOD ALLOWING SELY
WINDS TO INCREASE DURING THE AFTN. SCEC CONDITIONS WILL BE POSSIBLE
FRI AFTN/EVENING MAINLY DUE AN INCREASING WIND.

SATURDAY THROUGH TUESDAY...MODERATE TO STRONG SOUTHEAST WINDS WILL
PREVAIL ACROSS THE COASTAL WATERS SATURDAY THROUGH EARLY SUNDAY
AS THE PRESSURE GRADIENT REMAINS STRONG ACROSS THE WESTERN GULF OF
MEXICO BEFORE A COLD FRONT APPROACHES THE AREA SUN NIGHT. WINDS WILL
DIMINISH LATE SUNDAY INTO EARLY MONDAY AS A RESULT AS THE GRADIENT
RELAXES. WINDS SHOULD SHIFT TO THE NORTH AND INCREASE MON NIGHT
INTO TUESDAY AS HIGH PRESSURE BUILDS INTO DEEP SOUTH TX IN THE
WAKE OF A FRONTAL PASSAGE LATE MONDAY.

FIRE WEATHER...OUR ATTENTION WILL FOCUS ACROSS OUR WESTERN COUNTIES
BY MIDDAY AND AFTERNOON FRIDAY. SOUTHEASTERLY WINDS ARE EXPECTED TO
RETURN OVERNIGHT TONIGHT AND TOMORROW. THESE WINDS ARE ANTICIPATED
TO INCREASE BY THE MIDDAY AND AFTERNOON HOURS. SLOW LLVL MOISTURE
RECOVER IS ANTICIPATED TO OCCUR AS DEW POINT TEMPERATURES REMAIN IN
THE UPPER 40S/LOW 50S ACROSS THE WESTERN THIRD OF DEEP SOUTH TX ON
FRIDAY AFTERNOON. AS TEMPERATURES WARM DURING THE DAY...RH VALUES
WILL FALL INTO THE 20 TO 30 PERCENT RANGE INCREASING THE THREAT FOR
WILDFIRE GROWTH AND SPREAD. AT THIS POINT...WIND SPEEDS LOOK
MARGINAL FOR RED FLAG WARNING CONDITIONS AND THE FORECAST
ENVIRONMENT LOOKS TO FALL MORE IN LINE WITH A RANGELAND FIRE
DISCUSSION. WILL LET FUTURE SHIFTS EXAMINE NEW MODEL DATA...BUT
ANTICIPATE AN RFD PRODUCT WILL COVER THE FIRE WEATHER CONCERN ON
FRIDAY.
