AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KEY WEST FL
1014 PM EST FRI JAN 30 2015

.DISCUSSION...
SKIES ARE MOSTLY CLEAR AT THIS HOUR WITH THIN CI REMAINING NORTH OF
THE KEYS. WINDS ARE OSCILLATING IN SPEED LOCALLY...BUT UPSTREAM
ACROSS THE NEARSHORE WATERS ADJACENT TO THE PENINSULA WE SEE FRESH
TO OCCASIONALLY STRONG BREEZES SLIDING SOUTHWARD. TEMPERATURES ARE
CURRENTLY IN THE MID 60S ALONG THE ISLAND CHAIN.

THE LATE EVENING LOCAL SOUNDING SHOWS THE NORTHERLY WINDS HAVE
DEEPENED THROUGH AT LEAST 10000 FEET AND ACCELERATED THROUGH MUCH OF
THAT DEPTH OVER THE PAST 12 HOURS. THE FRONT ACROSS THE PENINSULA IS
EXPECTED TO PASS THROUGH THE KEYS AND SURROUNDING WATERS LATER IN THE
OVERNIGHT PERIOD. WE ARE NOT EXPECTING MUCH...IF ANYTHING...IN THE
WAY OF PRECIPITATION AS THIS PASSES THROUGH. IN FACT...NOT A
SIGNIFICANT THERMAL MODIFICATION OF THE AIRMASS IS EXPECTED LOCALLY.
WE DO EXPECT NORTH/NORTHEAST WINDS TO ACCELERATE ALL THE WAY TO THE
SURFACE LATER IN THE OVERNIGHT PERIOD. THE AFTERNOON ZONE FORECAST
HAS THE EXPECTED CONDITIONS COVERED WELL. NO UPDATE IS PLANNED AT
THIS TIME.

&&

.MARINE...
WIND SPEEDS SHOULD DAMPEN AND AMPLIFY OVER THE NEXT COUPLE OF HOURS
AHEAD OF A DRY FRONTAL PASSAGE...EXPECTED TO OCCUR LATER IN THE
OVERNIGHT PERIOD. MAY BE ADVERTISING CONDITIONS A BIT QUICKLY AND
POSSIBLY ERRING ON THE SIDE OF CAUTION...BUT PREFERRED TO RAISE A
SMALL CRAFT ADVISORY HEADLINE FOR ALL WATERS SURROUNDING THE FLORIDA
KEYS AS WINDS ACCELERATE FROM THE NORTH/NORTHEAST LATE IN THE
OVERNIGHT PERIOD. THIS DECISION WAS HEAVILY BASED ON THE DEPICTION OF
THE HRRR SOLUTIONS OVER THE PAST FEW HOURS. AGAIN...CONDITIONS MAY BE
CLOSER TO SUNRISE...BUT THE CONFIDENCE HAS INCREASED THROUGH THE LATE
EVENING. FRESH TO OCCASIONALLY STRONG BREEZES WILL TURN MORE TO THE
EAST THROUGH THE DAY SATURDAY. SO...RECREATIONAL BOATING CONDITIONS
WILL CERTAINLY NOT BE IDEAL ON ANY OF THE WATERS SURROUNDING THE
FLORIDA KEYS AT LEAST THROUGH THE FIRST HALF OF THIS WEEKEND.

&&

.AVIATION...
...31/00Z TAF ISSUANCE...TWO SIGNIFICANT WIND CHANGES ARE EXPECTED
THROUGH EARLY SATURDAY. THE FIRST WILL BE A MODERATE INCREASE IN
NORTHEAST WINDS AROUND DAYBREAK AS A RESULT OF A DRY FRONTAL
BOUNDARY PASSING THE KEYS. THE SECOND WILL BE A RESULT OF A BUILDING
HIGH ACROSS SOUTH FLORIDA...AND WILL BRING MORE GUSTY EASTERLY WINDS
ACROSS THE ISLAND CHAIN AFTER MID MORNING AND PERSISTING THROUGH THE
REMAINDER OF THE PERIOD. OTHER THAN WIND SHIFTS...NO SIGNIFICANT
CHANGES IN FLIGHT CONDITIONS ARE EXPECTED...AS VFR SHOULD PREVAIL
THROUGH THE PERIOD.

&&

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