AREA FORECAST DISCUSSION FOR THE FLORIDA KEYS
NATIONAL WEATHER SERVICE KEY WEST FL
1012 PM EDT WED JUN 12 2013

.DISCUSSION...
SEVERAL EPISODES OF SHOWERS...ACCOMPANIED BY A FEW
THUNDERSTORMS...FLARED OVER PORTIONS OF THE KEYS SINCE THE MIDDLE OF
THE DAY. LOCATIONS IN THE LOWER KEYS RECORDED WELL OVER 3
INCHES...WITH KEY WEST INTERNATIONAL AIRPORT RECORDING A NEW RECORD
OF 3.03 INCHES THUS FAR THROUGH THE CALENDAR DAY. CURRENTLY...SEVERAL
SMALL CLUSTERS OF SHOWERS AND THUNDERSTORMS ARE PUSHING SOUTHWESTWARD
NEAR THE MIDDLE AND LOWER KEYS AND EXTENDING INTO THE ATLANTIC
WATERS. UNDER PARTLY TO MOSTLY CLOUDY SKIES AT THIS HOUR ALONG THE
KEYS ISLAND CHAIN...TEMPERATURES ARE IN THE LOWER 80S...WITH A LIGHT
BREEZES VARYING IN DIRECTION.

THE LATE EVENING LOCAL SOUNDING SHOWS THE LIGHT BREEZES EXTENDING
THROUGH ABOUT 5000 FEET...WITH STRONGER WINDS BACKED TO THE NORTH
THROUGH ABOUT ABOUT 20000 FEET. ALTHOUGH THERE IS EVIDENCE OF DRIER
AIR INTRUDING ALOFT...WE REMAIN RELATIVELY MOIST AND UNSTABLE. AND AS
WITH THE LAST COUPLE OF EVENINGS/OVERNIGHT PERIODS...SEVERAL LOW
LEVEL BOUNDARIES WILL BE WORKING THROUGH THE SERVICE AREA TONIGHT.
WAS DEBATING REDUCING OUR PROBABILITY OF MEASURABLE
PRECIPITATION...THE LATEST LOOP OF OUR LOCAL KBYX RADAR SUGGESTS
KEEPING WHAT WE CURRENTLY HAVE ADVERTISED. A CHANCE OF SHOWERS AND
THUNDERSTORMS WILL BE MAINTAINED...AND THE UPCOMING ZONE UPDATE WILL
REMOVE SOME TIMED WORDING IN THE FIRST PERIOD. ALL OF THE OTHER
SENSIBLE WEATHER ELEMENTS ARE IN LINE.

&&

.MARINE...
EXPECT NO CHANGES TO THE LATE EVENING COASTAL WATERS FORECAST. WINDS
WILL BE LIGHT...VARYING IN DIRECTION OVER A LARGE PORTION OF THE
SERVICE AREA AND AN EAST/SOUTHEASTERLY COMPONENT MAINLY IN THE
ATLANTIC WATERS.

&&

.AVIATION...
EXPECT MOSTLY VFR CONDITIONS AT BOTH THE KEY WEST INTERNATIONAL AND
MARATHON ISLAND TERMINALS OVERNIGHT. BRIEF PERIODS OF MVFR VSBYS AND
OR CEILINGS ARE POSSIBLE DUE TO LINGERING BOUNDARIES INTERACTING WITH
CLOUDLINES THROUGH 04Z. AS THE CLOUD LINE REDEVELOPS DURING THE DAY
EXPECT TO SEE SIMILAR MVFR/IFR CONDITIONS AFTER 13/15Z ESPECIALLY
NEAR KEY WEST. WINDS WILL REMAIN LIGHT AND VARIABLE.

&&

.CLIMATE...
ON THIS DATE IN KEYS WEATHER HISTORY...1946...2.67 INCHES OF RAIN
FELL ON KEY WEST SETTING THE DAILY RECORD FOR RAINFALL ON JUNE
12TH IN KEY WEST. THIS RECORD WAS SHATTERED TODAY AS 3.03 INCHES OF
RAIN FELL AT THE KEY WEST INTERNATIONAL AIRPORT...SO FAR. RAINFALL
RECORDS AT KEY WEST DATE BACK TO 1871.
