.DISCUSSION...
.CURRENTLY...
SKIES ARE PARTLY CLOUDY WITH BOTH ZONALLY PASSING UPPER LEVEL CLOUD
COVER...AND LOW LEVEL TRADE WIND INDUCED CUMULUS DECKS. EARLIER
SHOWER ACTIVITY OVER THE STRAITS OF FLORIDA HAS DISSIPATED...LEAVING
ONLY FALSE ECHO RETURNS ACROSS THE SERVICE AREA. ISLAND WINDS ARE
GENERALLY EASTERLY AT 10 TO 15 MPH...AND MOST MARINE OBSERVING
STATIONS ARE REPORTING 15 TO 20 KNOT EAST-SOUTHEASTERLY CONDITIONS.
MORNING KKEY SOUNDING CAME IN WITH SEASONALLY MOIST AND UNSTABLE
CONDITIONS UP TO 800 MB...WHERE A VERY PRONOUNCED SUBSIDENT
INVERSION OF NEAR 15 DEGREES FAHRENHEIT IS FOUND. TEMPERATURES/DEW
POINTS HAVE BOTH CLIMBED OVER THE PAST 12 HOURS DUE TO THE INCREASING
EAST-SOUTHEASTERLY FLOW. TEMPS ARE IN THE LOW 70S AND DEW POINTS ARE
NEAR 60.

.FORECAST...
NO SIGNIFICANT CHANGES WERE REQUIRED TO THE TEXT FORECASTS OR GRIDS
THIS CYCLE. ONLY UPDATE TO THE ZFP WAS TO REMOVE TRANSITIONAL WORDING
FOR THIS AFTERNOON. TEMPS WILL RISE TO THE MID 70S TODAY AND WINDS
WILL CONTINUE THEIR GRADUAL VEERING TO THE SOUTH BY TONIGHT BEFORE
SHIFTING WEST-SOUTHWEST BY TUESDAY. TEMPERATURES AND DEW POINTS WILL
BE SLIGHTLY ABOVE NORMAL DUE TO THIS WIND REGIME THROUGH LATE
TUESDAY. A FRONTAL PASSAGE ON WEDNESDAY WILL BRING A FEW PERIODS OF
HIGHER RAIN CHANCES...THEN COOLER AND DRIER CONDITIONS THROUGH THE
REST OF THE WEEK.

&&

.MARINE...
MARINE FORECAST UPDATE THIS FORECAST CYCLE INCLUDES HEADLINES FOR
CAUTIONARY CONDITIONS AS WINDS WILL SURGE THROUGH THE AFTERNOON
HOURS. A FEW OBSERVING STATIONS IN THE ATLANTIC WATERS HAVE BEEN
BORDERLINE FOR A SCA AT THIS TIME...BUT EXPECT 1 TO 2 KNOTS OF
SLACKENING TO OCCUR IN THE WINDS AFTER NOON. THEREAFTER...NO CHANGES
WERE NECESSARY TO THE TEXT MARINE FORECASTS.

&&

.AVIATION...
VFR CONDITIONS WILL PREVAIL AT EYW AND MTH TODAY AND TONIGHT.
SUSTAINED EAST TO SOUTHEAST WINDS OF 20 TO 25 KNOTS FROM JUST OFF

TO 20 KNOTS TONIGHT.
