AVIATION...
THE WINDS WILL REMAIN SOUTHEAST LESS THAN 10 KNOTS TONIGHT ALONG
ALL OF THE TAF SITES IN SOUTH FLORIDA BEFORE INCREASING TO 10 TO
15 KNOTS DURING WEDNESDAY. THE ONLY EXCEPTION TO THIS IS THAT APF

PREV DISCUSSION... /ISSUED 640 PM EDT TUE MAY 5 2009/

MARINE...ANTICIPATE NO CHANGES.

PREVIOUS DISCUSSION...SURFACE TROUGH TODAY IS POSITIONED FROM THE
BERMUDA AREA TO CENTRAL FLORIDA AND IS RELATIVELY WEAK OVER FLORIDA.
SURFACE TROUGH AND MID LEVEL LOW NORTH OF THE DOMINICAN REPUBLIC
WILL MOVE NORTH AND DISSIPATE BY FRIDAY AND THE SURFACE RIDGE WILL
MOVE SOUTH TO S OF 28N TO SOUTH FLORIDA. THE HIGHEST CHANCE OF
PRECIP THROUGH THE PERIOD WILL BE SLIGHT AND ENHANCED BY THE WEST
COAST SEA BREEZE AND EXPECT SOME RAIN OVER PARTS OF THE NORTHWEST.
ENOUGH INSTABILITY CAN BE EXPECTED FOR A POSSIBILITY OF THUNDER EACH
AFTERNOON NORTHWEST STARTING THURSDAY. A SLIGHT CHANCE OF LOW TOPPED
SHOWERS CAN BE EXPECTED THURSDAY NIGHT ON THROUGH EARLY NEXT WEEK.
MID LEVEL HIGH PRESSURE WILL PREVENT THE FRONT COMING OFF THE
CAROLINA COAST AND THE SOUTHEAST FROM MAKING MUCH PROGRESS SOUTH AND
LOOKS LIKE IT MAY NOT EVEN GET INTO FLORIDA NOW.

MARINE...A LIGHT TO GENTLE MOSTLY SOUTHEAST WIND FLOW (AOB 10 KTS)
SHOULD CONTINUE INTO NEXT WEEKEND WITH SEAS MOSTLY AT 2 FEET OR
LESS THROUGH THE ENTIRE FORECAST PACKAGE.

FIRE WEATHER...INCREASED FIRE DANGER EXPECTED AGAIN OVER NORTHWEST
INTERIOR SECTIONS THIS AFTERNOON AS THE COMBINATION OF TEMPS IN
THE UPPER 80S TO THE LOWER 90S AND DEW POINTS IN THE UPPER 50S
WILL RESULT IN RH VALUES FALLING BELOW 35 % ACROSS GLADES...HENDRY
AND POSSIBLY OVER NORTHERN PORTIONS OF COLLIER COUNTIES FOR FOUR
OR MORE HOURS. THEREFORE, A RED FLAG WARNING CONTINUES FOR THOSE
COUNTIES. RH SHOULD REMAIN WELL ABOVE 35% OVER THE REST OF SOUTH
FLORIDA. A FIRE WEATHER WARNING HAS BEEN ISSUED FOR GLADES AND
HENDRY COUNTIES WEDNESDAY SINCE DEW POINTS WILL STILL BE IN THE
UPPER 50S DURING MAX HEATING. A PERSISTENT SE FLOW WILL RESULT IN
DEW POINTS GRADUALLY CLIMBING UP THROUGH THIS WEEK, WITH MIN RH
VALUES REMAINING ABOVE CRITICAL LEVELS STARTING AFTER MID WEEK.
