AREA FORECAST DISCUSSION FOR THE FLORIDA KEYS
NATIONAL WEATHER SERVICE KEY WEST FL
950 AM EST THU DEC 18 2014

.DISCUSSION...
UNDER MOSTLY SUNNY SKIES WITH A LIGHT BREEZE VARYING FROM NORTH TO
EAST...TEMPERATURES IN THE KEYS ARE CLIMBING THROUGH THE LOWER 70S.
KBYX IS VOID OF PRECIPITATION ECHOES.

THE MORNING SOUNDING SHOWS JUST A TAD MORE MOISTURE IN THE LOWEST 5000
FEET THANKS TO BREEZES TURNING MORE TO THE EAST IN THAT LAYER ABOVE
THE SURFACE. BUT WE STILL REMAIN QUITE STABLE UNDER A VERY DRY
CAPPING MID LAYER. TEMPERATURES AT THIS HOUR ARE RUNNING ABOUT A
DEGREE ABOVE THE READINGS 24 HOURS AGO. MAY ADD A DEGREE TO OUR
GRIDDED DAYTIME MAX TEMPERATURES BASED ON THE MAX READINGS ACHIEVED
YESTERDAY. BUT THIS DOES NOT AFFECT THE ADVERTISED HIGHS FOR TODAY FROM
OUR EARLIER ISSUANCE. A ZONE UPDATE WILL LIKELY BE ISSUED IN A SHORT
WHILE JUST TO REMOVE SOME TRANSITIONAL WIND WORDING FROM THE PREVIOUS
PACKAGE.

&&

.MARINE...
ASIDE FROM VERY SMALL WORDING ADJUSTMENTS TO THE INITIAL WIND
DIRECTIONS...NO OTHER CHANGES WILL BE INSERTED TO THE UPCOMING
COASTAL WATERS UPDATE. RECREATIONAL BOATERS CAN EXPECT VERY AGREEABLE
CONDITIONS IN MOST WATERS SURROUNDING THE FLORIDA KEYS IN THE NEAR
TERM.

&&

.AVIATION...
VFR CONDITIONS ARE EXPECTED THROUGH THE TAF PERIOD AT BOTH THE KEY
WEST INTERNATIONAL AND MARATHON ISLAND TERMINALS. SURFACE WINDS MAY
DECOUPLE OVERNIGHT ESPECIALLY AT THE MARATHON TERMINAL...BECOMING
LIGHT AND VARIABLE.

&&
