AREA FORECAST DISCUSSION FOR THE FLORIDA KEYS
NATIONAL WEATHER SERVICE KEY WEST FL
956 AM EDT MON MAY 20 2013

.DISCUSSION...
ISOLATED TO SCATTERED SHOWERS ARE MOVING NORTHWESTWARD THROUGH THE
ATLANTIC WATERS ADJACENT TO THE MIDDLE AND UPPER KEYS...ACROSS THE
ISLAND CHAIN INTO THE BAY AND ADJACENT GULF WATERS. LAYERED CLOUDS
ARE STARTING TO SHOW MORE PROMINENT BREAKS FROM JUST A FEW HOURS AGO
ALONG THE ISLAND CHAIN AND ADJACENT WATERS. WINDS ARE GENTLE FROM THE
EAST TO SOUTHEAST AS TEMPERATURES SLOWLY CLIMB THROUGH THE LOWER 80S.

EARLY MORNING VISIBLE SATELLITE IMAGES INDICATE THAT ADDITIONAL
BREAKS ARE EXPECTED IN THE LAYERED CLOUDS THROUGH THE AFTERNOON. THE
MORNING LOCAL SOUNDING SHOWS A MORE MOIST...UNSTABLE...AND
CONVECTIVELY UNINHIBITED AIRMASS IS NOW IN PLACE WHEN COMPARED TO THE
PREVIOUS FEW DAYS. WE EXPECT TO SEE SCATTERED SHOWERS THROUGH THE
DURATION OF THE AFTERNOON. AND A COUPLE THUNDERSTORMS CAN NOT BE
RULED OUT WITH A LOW AMPLITUDE MID LEVEL TROUGH NEARBY. SO...UNLESS
THE CLOUDS REMAIN STUBBORN OVER THE NEXT COUPLE OF HOURS...NO UPDATE
WILL BE ISSUED FOR THE ZONES THIS MORNING.

.MARINE...
EXPECT NO CHANGES ON THE LATE MORNING MARINE UPDATE. AWAY FROM
SCATTERED SHOWERS AND A FEW THUNDERSTORMS...GENTLE TO BRIEFLY
MODERATE EAST TO SOUTHEAST BREEZES WILL CONTINUE ACROSS ALL WATERS
SURROUNDING THE FLORIDA KEYS OVER THE NEXT COUPLE OF FORECAST
PERIODS.

.AVIATION...
VFR CONDITIONS WILL PREVAIL AT EYW AND MTH THIS MORNING INTO EARLY 
THIS AFTERNOON. MVFR OR LOWER CONDITIONS ARE CONCEIVABLE AT EYW AND 
MTH FROM LATE THIS AFTERNOON INTO THIS EVENING. THIS POSSIBILITY IS 
NOT GREAT ENOUGH TO PLACE IN THE TERMINAL FORECASTS AT THIS TIME. 
VFR CONDITIONS WILL PREVAIL AT EYW AND MTH TONIGHT. SUSTAINED EAST 
TO SOUTHEAST WINDS NEAR 10 KNOTS ARE EXPECTED FROM JUST OFF THE 
SURFACE TO ABOUT 8000 FEET.
