AREA FORECAST DISCUSSION FOR THE FLORIDA KEYS
NATIONAL WEATHER SERVICE KEY WEST FL
1053 PM EDT MON JUN 17 2013

.DISCUSSION...
SHOWERS REMAIN ISOLATED ON THE SOUTHERN AND EASTERN EXTREMES OF THE
SERVICE AREA...WITH A FEW WEAKER ECHOES ABOUT 30 NM SOUTH OF THE
MARQUESAS KEYS. THERE ARE A FEW THUNDERSTORMS ACCOMPANYING THE
STRONGER SOUTHERN CELLS. WINDS ARE GENTLE TO MODERATE FROM THE EAST
TO SOUTHEAST AND TEMPERATURES ARE BETWEEN 80 AND 85 DEGREES ALONG THE
KEYS ISLAND CHAIN.

THE LATE EVENING LOCAL SOUNDING SHOWS AN INCREASE IN MOISTURE IN THE
LOWEST LAYERS...THROUGH A DEPTH WHERE WINDS STILL REMAIN MODERATE. A
VEERED BUT SOMEWHAT LIGHTER PROFILE EXTENDS ABOVE THAT. PRECIPITABLE
WATER HAS INCREASED TO NEARLY 1.7 INCHES...AND WE ARE MORE UNSTABLE
THAN 24 HOURS AGO. THE HIGHER MOISTURE IS EXTENDING TO THE SOUTH AND
SOUTHEAST...GENERALLY UPSTREAM FROM THE KEYS ISLAND CHAIN. WE SHOULD
SEE AT LEAST A LITTLE HIGHER PROBABILITY/COVERAGE OF SHOWERS AND
THUNDERSTORMS THROUGH THE OVERNIGHT PERIOD. WILL LET THE AFTERNOON
ZONE ISSUANCE RIDE FOR NOW...BASED ON THE TRANSITIONAL WORDING FOR A
GREATER CHANCE OF PRECIPITATION THROUGH THE OVERNIGHT PERIOD.

&&

.MARINE...
NO CHANGES ON THE LATE EVENING MARINE UPDATE. A GENTLE TO MODERATE
EAST TO SOUTHEAST BREEZE IS EXPECTED ACROSS ALL MARINE ZONES THROUGH
THE OVERNIGHT PERIOD. EXPECT SCATTERED SHOWERS AND A FEW
THUNDERSTORMS THROUGH EARLY TUESDAY.

&&

.AVIATION...
VFR CONDITIONS WILL PREVAIL OVERNIGHT AT THE ISLAND TERMINALS.
SURFACE WINDS WILL RELAX OVERNIGHT TO AROUND 10 KNOTS OUT OF THE
EAST SOUTHEAST DIRECTION.

&&

.KEY WATCHES/WARNINGS/ADVISORIES...
