AREA FORECAST DISCUSSION FOR THE FLORIDA KEYS
NATIONAL WEATHER SERVICE KEY WEST FL
352 PM EDT MON MAR 19 2012

.DISCUSSION...
ISOLATED SHOWERS HAVE GENERALLY MOVED WESTWARD FROM THE FLORIDA KEYS
AND SURROUNDING COASTAL WATERS. PARTLY CLOUDY TO MOSTLY CLEAR SKIES
SHOULD PREVAIL THROUGH THE LATE EVENING... WITH ONLY FAIR WEATHER
CUMULUS OBSCURING THE SKIES. MODEL SOUNDINGS INDICATED A DRYING TREND
OVERNIGHT WHICH WOULD MAKE THE CASE FOR DIMINISHED RAIN
CHANCES. HOWEVER...HAVE LEFT THE SLIGHT CHANCES IN THROUGH THE
TONIGHT TIME PERIOD ON ACCOUNT OF THE VISIBLE SATELLITE IMAGERY THAT
SHOWS AN AREA OF INCREASED MOISTURE AND LIFT OVER THE BAHAMAS...WHICH
SHOULD ARRIVE NEAR THE UPPER KEYS AND SOUTH FLORIDA BY 10 PM. RAIN
SHOWERS GENERATED SHOULD BE ISOLATED AND RELATIVELY LIGHT IN
NATURE...SO 10 PERCENT SHOULD HANDLE THIS SITUATION WELL. FOR THE
LONG TERM PERIOD... MADE VERY FEW CHANGES... A PERSISTENT HIGH WILL
MAINTAIN THE STATUS QUO WITH LIMITED CHANGES IN WIND SPEED AND POPS
THROUGH THURSDAY. ON FRIDAY INTO THE WEEKEND...A FRONTAL SYSTEM WILL
APPROACH THE REGION AND WILL CAUSE A BIT OF A PATTERN CHANGE.... BUT
THE CONFIDENCE IN THESE SOLUTIONS IS LOW. MAINLY REFLECTED NEAR CLIMO
CONDITIONS FOR THAT PERIOD.

&&

.MARINE...HOISTING A SMALL CRAFT ADVISORY WITH THIS FORECAST PACKAGE.
THE CMAN WINDS PERSISTED MUCH OF THE NEAR THE 20 KNOT MARK... WITH
ISOLATED GUSTS TO 23 KNOTS AT THE HEIGHT OF THE SENSORS... BELIEVED
THIS TO BE ISOLATED UP UNTIL NOW...HOWEVER SEVERAL SHIP REPORTS HAVE
COME BACK AS WELL WITH NEAR 20 KNOT WINDS...AND MODELS ARE
INDICATING A SURGE INTO THIS EVENING. WINDS MAY FLUCTUATE FOR THE
NEXT FEW DAYS...HOWEVER A SCA THROUGH THE DAY ON WEDNESDAY OVER THE
STRAITS AND HAWK CHANNEL IS CERTAINLY POSSIBLE.

&&

.AVIATION...THROUGH 12Z...VFR CONDITIONS WILL PREVAIL AT THE KEY WEST AND
MARATHON TERMINALS WITH EAST WINDS OF 10 TO 15 KNOTS AND GUSTS NEAR
20 KNOTS.

&&

.KEY WATCHES/WARNINGS/ADVISORIES...
FL...NONE.
