AREA FORECAST DISCUSSION FOR THE FLORIDA KEYS
NATIONAL WEATHER SERVICE KEY WEST FL
1055 AM EST MON NOV 11 2013

.DISCUSSION...
SKIES RANGE FROM MOSTLY SUNNY TO MOSTLY CLOUDY THIS MORNING
DEPENDING ON YOUR EXACT LOCATION AROUND THE FLORIDA KEYS.
CURRENTLY...AIR TEMPERATURES ARE RISING THROUGH THE LOWER 80S IN
MOST KEYS ISLAND COMMUNITIES...WHILE DEWPOINTS ARE HOLDING IN THE
LOWER 70S. THE AIR MASS IN PLACE IS BORDERLINE MARITIME TROPICAL WITH
A FAIRLY DEEP LAYER OF EAST-NORTHEAST WINDS PREVAILING IN THE LOWEST
10000 FEET OF THE ATMOSPHERE SOUTH OF A MODIFIED CONTINENTAL POLAR
ANTICYCLONE. THE ATMOSPHERE IS MORE MOIST THAN USUAL THIS TIME OF
YEAR AS EVIDENCED BY A TOTAL PRECIPITABLE WATER VALUE WHICH IS NEARLY
TWO STANDARD DEVIATIONS ABOVE THE NOVEMBER MEAN. IN FACT...SCATTERED
TO LOCALLY NUMEROUS SHOWERS AND ISOLATED THUNDERSTORMS HAVE BEEN
PREVALENT IN THE OUTER TIER OF MARINE ZONES BEYOND ABOUT 20 NAUTICAL
MILES SOUTH OF THE KEYS FOR THE LAST SEVERAL HOURS WITH CELL MOVEMENT
MAINLY DUE WESTWARD. BOUNDARY-LAYER WIND ANALYSIS AND SATELLITE
IMAGERY SUGGEST AN OLD FRONTAL SHEAR LINE PRESENT HERE WITH
ASSOCIATED ENHANCED LOW-LEVEL MOISTURE CONVERGENCE/LOW-LEVEL ASCENT.

LITTLE CHANGE IS EXPECTED DURING THE FIRST PERIOD...AND NO
SIGNIFICANT ADJUSTMENTS WILL BE MADE TO THE FORECAST DATABASE UNTIL
LATER THIS AFTERNOON.
&&

.MARINE...
SMALL CRAFT SHOULD EXERCISE CAUTION OVER MOST ZONES THIS AFTERNOON AS
NORTHEAST TO EAST BREEZES BLOW A STEADY 15 TO 20 KNOTS. SOME HIGHER
GUSTS ARE LIKELY ACROSS THE STRAITS OF FLORIDA WHERE COVERAGE OF
SHOWERS AND A FEW THUNDERSTORMS WILL BE GREATER. SEAS OF 4-7 FEET ARE
EXPECTED IN THE STRAITS OF FLORIDA WITH HIGHEST WAVE HEIGHTS AND
STEEPNESS IN THE GULF STREAM.
&&

.AVIATION...
VFR WILL PREVAIL ACROSS BOTH ISLAND TERMINALS THROUGH THE TAF
PERIOD...WHILE SHOWER ACTIVITY REMAINS WELL SOUTH OF THE ISLAND
TERMINALS THROUGH.
&&

.CLIMATE...
ON THIS DATE IN KEYS WEATHER HISTORY...1980...TROPICAL STORM JEANNE
STALLED SEVERAL HUNDRED MILES WEST OF KEY WEST ON NOVEMBER
11TH...BUT PROVIDED 22.75 INCHES OF RAIN. THIS SET NOT ONLY THE
DAILY RECORD RAINFALL...BUT ALSO THE WETTEST DAY EVER RECORDED IN
KEY WEST.
