AREA FORECAST DISCUSSION FOR THE FLORIDA KEYS
NATIONAL WEATHER SERVICE KEY WEST FL
355 AM EST FRI JAN 30 2009

.DISCUSSION...
THE SURFACE AXIS OF HIGHER PRESSURE HAS SETTLED SOUTH OF THE KEYS.
KBYX WIND PROFILE...CUDJOE PROFILER...AND THE LATE EVENING LOCAL
SOUNDING INDICATES A DEEP...ALBEIT LIGHT...SOUTH TO SOUTHWEST WIND
EXTENDING THROUGH AROUND 10 KFT. KBYX RADAR SHOWS NO PRECIPITATION
ECHOES NEARBY...AND ONLY ISOLATED RETURNS WELL TO THE NORTHWEST IN
THE GULF OF MEXICO...IN CLOSE PROXIMITY OF THE LEADING EDGE OF THE
COLD FRONT. EARLY MORNING IR SATELLITE IMAGES INDICATE ONLY SMALL
CUMULUS PATCHES DRIFTING THROUGH THE STRAITS...AND EVEN FEWER
POCKETS ALONG THE REEF. TEMPERATURES ARE IN THE UPPER 60S TO AROUND
70 ALONG THE ISLAND CHAIN...WITH DEWPOINTS RANGING FROM THE LOWER
60S CLOSE TO THE MAINLAND TO THE UPPER 60S IN THE LOWER KEYS.

.FORECAST...
LITTLE CHANGE IN FORECAST REASONING FROM THE LAST FEW ISSUANCES.
WILL NEED TO INSERT PATCHY FOG FOR EARLY THIS MORNING THANKS TO THE
LIGHT PROFILE...MOSTLY CLEAR SKIES...AND HIGH SURFACE DEWPOINTS.
WILL HAVE TO KEEP AN EYE ON THIS FOR THE NEXT FEW HOURS...IN THE
RARE CHANCE VISIBILITIES PLUMMET IN SOME OF THE LARGER LOWER KEYS.
OTHERWISE...A DIGGING TROUGH IN THE SOUTHEAST PORTION OF THE COUNTRY
WILL BEGIN TO ACCELERATE THE COLD FRONT THAT IS CURRENTLY STRETCHED
ACROSS THE CENTRAL SECTION OF THE FLORIDA PENINSULA SOUTHWARD TODAY.
ALL SHORT RANGE GUIDANCE IS IN CLOSE TEMPORAL AGREEMENT IN REGARDS
TO THE DIRECTIONAL SHIFT AND STEADY INCREASE IN WIND SPEEDS THROUGH
LATE THIS MORNING AND AFTERNOON. THE BEST MID LEVEL ENERGY REMAINS
SHUNTED NORTH AND NORTHEAST OF OUR LATITUDE AS THE FRONT PASSES
THROUGH EARLY THIS AFTERNOON. WE WILL SEE CLOUDS INCREASE AHEAD OF
THE FRONT THIS MORNING...BUT RAIN CHANCES WILL REMAIN IN THE LOWER
RANGE OF CHANCE TODAY. TEMPERATURES IN THE LOWER TO MIDDLE 70S ALONG
THE ISLAND CHAIN THROUGH THE MORNING WILL BEGIN TO DROP THROUGH THE
AFTERNOON WITH THE ONSET OF BREEZY NORTHERN CONDITIONS. WINDY
CONDITIONS WILL PERSIST TONIGHT DRAGGING QUITE COOL TEMPERATURES
INTO ALL OF THE KEYS. THICKNESSES AND TEMPERATURES ALOFT SUGGEST
UNDERCUTTING MOS GUIDANCE TEMPERATURES BY A FEW DEGREES FOR
TONIGHT...SO WILL MAINTAIN A 50 TO 55 DEGREE RANGE ALONG THE ISLAND
CHAIN. SATURDAY WILL BE COOL AS WELL WITH TEMPERATURES STRUGGLING TO
GET MUCH HIGHER THAN THE LOWER 60S THANKS TO A STEADY AND BREEZY
NORTH TO NORTHEAST WINDS. WILL MAKE THAT MINOR WORDING ADJUSTMENT
FOR THAT PERIOD ON THIS FORECAST.

THE MID TO UPPER LEVEL TROUGH PULLS WELL EAST OF THE COAST BY EARLY
SUNDAY...ALLOWING THE TRAILING SURFACE HIGH PRESSURE TO EXPAND
EASTWARD...AND BECOME CENTERED IN THE WESTERN ATLANTIC BY LATE
SUNDAY AND EARLY MONDAY. ANOTHER STRONG DIGGING TROUGH WILL BRING
ANOTHER COLD FRONT THROUGH SOUTH FLORIDA AND THE KEYS BY EARLY
TUESDAY MORNING. LONG RANGE GUIDANCE NUMBERS SUGGEST EVEN LOWER
OVERNIGHT TEMPERATURES BY A COUPLE OF DEGREES FOR BOTH TUESDAY NIGHT
AND WEDNESDAY NIGHT WHEN COMPARED TO THE EXPECTED CONDITIONS
TONIGHT. WILL NOT MAKE ANY ADJUSTMENTS TO EITHER THOSE GRIDDED
TEMPERATURES OR THE SMALL CHANCE OF SHOWERS FROM MONDAY THROUGH
EARLY TUESDAY MORNING ON THIS FORECAST.

.MARINE...
STRENGTHENING NORTHWESTERLY WINDS DO NOT BEGIN UNTIL ROUGHLY THE
MIDDLE OF THE DAY...BUT SMALL CRAFT ADVISORY CONDITIONS WILL
ENCOMPASS ALL OF THE SERVICE AREA BY LATE TODAY. SO THE ADVISORY HAS
BEEN INCLUDED IN THIS UPCOMING FORECAST. THE ADVISORY WILL CONTINUE
THROUGH TONIGHT AND SATURDAY AS WINDS VEER MORE TOWARDS THE
NORTHEAST. THERE IS A GOOD CHANCE THAT A SMALL CRAFT FOR HAZARDOUS
SEAS WILL CONTINUE INTO SUNDAY ACROSS THE STRAITS. MORE MODERATE
CONDITIONS WILL CONTINUE THROUGH MONDAY AHEAD OF ANOTHER
FRONT...WHICH IS EXPECTED TO MOVE THROUGH EARLY TUESDAY AND LIKELY
BRING AT LEAST CAUTIONARY CONDITIONS FOR SMALL CRAFT...POSSIBLY
ANOTHER ADVISORY.

&&

.AVIATION...
VFR CONDITIONS WILL PREVAIL THROUGH THE REMAINDER OF THE MORNING.
LIGHT WINDS WILL RESULT IN HAZY VFR CONDITIONS AROUND SUNRISE AND
PATCHY GROUND FOG IN SHELTERED AREAS. A COLD FRONT WILL MOVE ACROSS
THE KEYS THIS AFTERNOON...RESULTING IN OVERCAST MOSTLY VFR
CONDITIONS AND STRONG NORTHWEST TO NORTH CROSSWINDS AT THE ISLAND
TERMINALS. A PERIOD OF MVFR CEILINGS ARE POSSIBLE FOR A FEW HOURS
AFTER FRONTAL PASSAGE AS COLD AIR STRATOCU STREAMS ACROSS THE KEYS.
