AREA FORECAST DISCUSSION FOR THE FLORIDA KEYS
NATIONAL WEATHER SERVICE KEY WEST FL
349 PM EST TUE JAN 21 2014

.DISCUSSION...
CURRENT WEATHER SUMMARY -- WINDS AT LOW ALTITUDES OVER THE FLORIDA
KEYS AND ADJACENT COASTAL WATERS ARE INCREASING RAPIDLY AS A LARGE
WINTER CYCLONE INTENSIFIES OFF THE EASTERN SEABOARD. THE KEY WEST
DOPPLER VAD WIND PROFILE SHOWS WEST WINDS AVERAGING 30-35 KNOTS
THROUGH THE LOWEST 15000 FEET...AND WE HAVE SEEN AN ACCELERATION IN
SHOWER MOVEMENT DURING THE LAST SIX HOURS OR SO...WITH SOME AREAS
LIKELY EXPERIENCING WIND GUSTS NEAR 30 KNOTS PLUS IN AND NEAR
HEAVIER DOWNPOURS OF RAIN. SURFACE WINDS HAVE SHIFTED TO WEST-
NORTHWEST MOST AREAS...AND ARE INCREASING FROM WEST TO EAST.
UPSTREAM OBSERVATIONS INDICATE WNW WINDS 20-25 KNOTS AND BUILDING
SEAS. SKIES HAVE TURNED CLOUDY...WITH AIR TEMPERATURES NOW BELOW 70F
MOST AREAS THANKS TO CLOUD COVER...RAIN...AND WIND OFF COLDER WATER.

WEATHER FORECAST HIGHLIGHTS NEXT 24 HOURS -- THE WINTER CYCLONE
CURRENTLY DEVELOPING OFF THE MID-ATLANTIC STATES WILL INTENSIFY INTO
A LARGE GALE CENTER AS IT MOVES NORTHEASTWARD OVER THE OPEN WESTERN
NORTH ATLANTIC. THIS WILL HELP BRING A ROBUST...BUT SHORT-LIVED WIND
SURGE AND HEALTHY DOSE OF COLD THERMAL ADVECTION TO THE FLORIDA KEYS
TONIGHT AND EARLY WEDNESDAY. HOWEVER...NORTH WINDS SHOULD BE
SLACKENING ABRUPTLY DURING THE AFTERNOON AS THE GALE CENTER PULLS
FARTHER AWAY AND A CONTINENTAL HIGH PRESSURE CELL SETTLES QUICKLY
SOUTHWARD OVER THE GULF OF MEXICO. TEMPERATURES WILL DIP TO 58-62F
TONIGHT...AND LIKELY WILL NOT RISE MORE THAN A FEW DEGREES ON
WEDNESDAY AS THE COOL...NORTH BREEZES BLOW. CLOUDY SKIES WILL TURN
PARTLY CLOUDY LATE TONIGHT...AND CLEAR EARLY WEDNESDAY OVER UPPER
KEYS COMMUNITIES FIRST...THENCE OVER THE LOWER KEYS AS STRATOCUMULUS-
BEARING WINDS TURN NORTH OFF THE DRIER/MORE STABLE MAINLAND BOUNDARY
LAYER.

WEATHER FORECAST HIGHLIGHTS THURSDAY-TUESDAY -- A MEAN LONG-WAVE
TROUGH WILL PERSIST ACROSS THE EASTERN UNITED STATES WITH RAPIDLY
MOVING/EVOLVING SURFACE SYSTEMS OF CONTINENTAL ORIGIN AFFECTING THE
FLORIDA KEYS. THIS WILL KEEP TEMPERATURES GENERALLY BELOW AVERAGE FOR
MOST OF THIS PERIOD. IN ADDITION...SKIES SHOULD AVERAGE OUT MOSTLY
CLEAR WITH NEAR NIL TO ONLY VERY SLIGHT MEASURABLE RAIN CHANCES.
&&

.MARINE...
A COLD FRONT CURRENTLY MOVING OVER THE CENTRAL GULF OF MEXICO... WILL
MOVE RAPIDLY SOUTHEASTWARD THIS EVENING...AND SWEEP THROUGH THE
FLORIDA KEYS OVERNIGHT. LOCAL BREEZES WILL FRESHEN TONIGHT...BECOMING
STRONG MOST AREAS BY DAYBREAK. WINDS WILL SHIFT NORTH LATE AND RELAX
WEDNESDAY...AS A HIGH PRESSURE CELL SHIFTS CLOSER TO THE FLORIDA
KEYS. THE NEXT HIGH PRESSURE SYSTEM BUILDING SOUTHWARD OVER THE
EASTERN UNITED STATES...WILL BRIEFLY FRESHEN NORTHEAST BREEZES ON
FRIDAY.
&&

.AVIATION...
PERIODIC MODERATE TO HEAVY SHOWERS MAY IMPACT THE TERMINALS THROUGH
THE EARLY EVENING HOURS WITH BRIEF PERIODS OF IFR CONDITIONS AND
MORE PROLONGED PERIODS OF MVFR CONDITIONS POSSIBLE IN TRAINING
SHOWERS. THEREAFTER...NNW WINDS WILL BUILD IN GRADUALLY THROUGH LATE
TONIGHT...WITH MODERATE CROSSWINDS POSSIBLE AT AREA RUNWAYS.
