AREA FORECAST DISCUSSION FOR THE FLORIDA KEYS
NATIONAL WEATHER SERVICE KEY WEST FL
248 PM EST THU DEC 25 2014

.DISCUSSION...
CURRENTLY - HIGH PRESSURE IS CONSOLIDATING OVER THE SOUTHEASTERN
UNITED STATES...AS A COOL AIR IN WAKE OF THIS MORNINGS COLD FRONT
CONTINUES TO FLOW SOUTHWARD THROUGH THE KEYS. WINDS ARE QUITE
VARIABLE ACROSS THE SERVICE AREA...WITH WINDS 10 TO 15 KNOTS IN THE
LEE OF SOUTH FLORIDA...BUT CLOSER TO 20 KNOTS OVER OUR WESTERN ZONES.
RESIDUAL WEAK SHOWER ACTIVITY REMAINS ACROSS THE OUTER EASTERN
FLORIDA STRAITS AS THE SURFACE FRONTAL BOUNDARY BEGINS TO DECAY.
SKIES HAVE BEEN QUITE VARIABLE THIS AFTERNOON...WITH PERIODS OF
MOSTLY CLEAR SKIES...MIXED WITH OVERCAST PERIODS. THIS IS DUE TO
A STILL SATURATED AND FAST VEERING FLOW THROUGH THE LOWER
LEVELS...CONTRIBUTING TO THE DEVELOPMENT OF LOW ALTO DECKS. THE KEYS
THEMSELVES HAVE BEEN RAIN FREE THROUGH THE AFTERNOON. DESPITE THE
PASSAGE OF THE COLD FRONT...COLD AIR ADVECTION WAS WEAK...AND WATER
TEMPERATURES ARE WARM. AS A RESULT...TEMPERATURES WERE ABLE TO REACH
INTO THE LOW TO MID 70S. DEW POINTS HAVE LINGERED IN THE MID 60S.

FORECAST - WINDS ARE EXPECTED TO INCREASE OUT OF THE NORTH...BECOMING
BREEZY ACROSS MUCH OF THE FORECAST AREA...THEN TURN NORTHEAST TOWARDS
MORNING AS THE PREVIOUSLY MENTIONED HIGH OVER THE SOUTHEASTERN UNITED
STATES EXPANDS EASTWARD. THE GRADIENT WILL RELAX TOWARDS
MORNING...AND WINDS WILL SLACKEN OUT OF THE NORTHEAST TO EAST TOWARDS
MORNING. NO COLD AIR ADVECTION IS EXPECTED TONIGHT...AND
TEMPERATURES WILL BE LUCKY TO DIP MUCH BELOW 60. LOWER LEVEL VEERING
THROUGH A STILL SATURATED LAYER MAY PROVIDE ENOUGH FORCING FOR A FEW
SHOWERS OVERNIGHT.

RESIDUAL LOW LEVEL MOISTURE WILL WASH OUT AND LIFT NORTH OF OUR AREA
ON FRIDAY...AND THE WIND PROFILE WILL WEAKEN AND BECOME LESS
ORGANIZED AS LOW LEVEL HIGH PRESSURE BECOMES BETTER ESTABLISHED OVER
EXTREME SOUTH FLORIDA AND THE BAHAMAS. A CLEARING AND WARMING TREND
WILL SET UP WITH WINDS LIGHT TO GENTLE MAINLY OUT OF THE EAST. EXPECT
TEMPERATURES TO BE NEAR OR SLIGHTLY ABOVE NORMAL ON FRIDAY WITH DEW
POINTS IN THE MID TO UPPER 60S.

THE SURFACE HIGH TO OUR NORTH WILL SETTLE SOUTHEASTWARD AND ELONGATE
EASTWARDS INTO THE ATLANTIC OVER THE WEEKEND INTO EARLY NEXT WEEK.
GENTLE TO MODERATE EAST WINDS WILL GRADUALLY FADE OUT AND TREND MORE
EAST SOUTHEAST THROUGH THIS PERIOD. HIGHS AND LOWS WILL GRADUALLY
GLIDE UPWARDS. DEEP LAYERED RIDGING ACROSS THE AREA WILL KEEP POPS
OUT OF THE FORECAST.

&&

.MARINE...
WINDS WILL BECOME MORE UNIFORMLY MODERATE TO FRESH OUT OF THE NORTH
THIS EVENING AS HIGH PRESSURE CONSOLIDATES OVER THE SOUTHEASTERN
UNITED STATES. THIS HIGH WILL EXPAND EASTWARD LATER IN THE NIGHT AND
WINDS WILL SWING NORTHEASTERLY...THEN RELAX TOWARDS DAY BREAK AS THE
LOCAL PRESSURE GRADIENT RELAXES. THEREAFTER...THE PREVIOUSLY MENTIONED
HIGH WILL SETTLE SOUTHEASTWARD AND ELONGATE EASTWARD THIS WEEKEND
INTO NEXT WEEK...RESULTING IN A GRADUAL VEERING AND SLACKENING OF
SURFACE WINDS.

&&

.AVIATION...
VFR CONDITIONS EXPECTED THIS AFTERNOON AT THE KEY WEST AND MARATHON
TERMINALS. NORTH WINDS AT AROUND 10 KNOTS WITH GUSTS UP TO 18 KNOTS
ARE EXPECTED AT MARATHON WITH FEW KNOTS HIGHER AT KEY
WEST...SHIFTING FROM THE NORTHEAST LATER TONIGHT. MVFR CIGS ARE
POSSIBLE LATER TONIGHT ACROSS THE KEYS. TIMING IS UNCERTAIN AND WILL
BE ADDRESSED WITH AMENDMENTS...AS NECESSARY.

&&

.CLIMATE...
ON THIS DATE IN KEYS WEATHER HISTORY...IN 1989...KEYS RESIDENTS HAD
AS CLOSE AS THEY HAVE EVER GOTTEN TO A WHITE CHRISTMAS...WITH A LOW
TEMPERATURE OF 46F AND A HIGH TEMPERATURE OF ONLY 54F...BOTH DAILY
RECORDS. ALSO IN 1873...THE DAILY RECORD RAINFALL OF 2.33" WAS
RECORDED.
