AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KEY WEST FL
253 PM EST SAT JAN 23 2016

.DISCUSSION...
CLOUDS ARE BREAKING MORE NOTICEABLY ACROSS THE UPPER KEYS THIS
AFTERNOON. THE STRONG NORTHWESTERLY WINDS CONTINUE TO CARRY PACKED
CUMULUS ACROSS THE LOWER AND MIDDLE KEYS. TEMPERATURES ALONG THE
ISLAND CHAIN WERE 65 OR 66 DEGREES AT ALL REPORTING STATIONS AT THE
TOP OF THE LAST HOUR. KBYX DOPPLER RADAR IS VOID OF PRECIPITATION
ECHOES AT THIS HOUR.

THE GRADIENT REMAINS TIGHT ACROSS THE LOCAL AREA...AND FRESH TO
STRONG NORTHWEST WINDS WILL CONTINUE OVER THE NEXT COUPLE OF HOURS.
THE AREA OF LOW PRESSURE CURRENTLY NEAR DELMARVA WILL LIFT
NORTHEASTWARD TONIGHT THROUGH SUNDAY. HIGH SURFACE PRESSURE WILL SINK
TO THE SOUTHEAST STATES AND ACROSS THE FLORIDA PENINSULA DURING THAT
TIME...AND AS A RESULT THE WINDS WILL DIMINISH WHILE TURNING TO THE
NORTH/NORTHEAST. MOISTURE WILL REMAIN QUITE LIMITED OVER THE NEXT FEW
PERIODS...AND SHALLOW RIDGING IN THE MID TO UPPER LEVELS WILL REPLACE
THE DEEP LOW PULLING AWAY FROM THE EAST COAST. WE WILL BE RELATIVELY
COOL THANKS TO VEERING WINDS...ESPECIALLY LATER TONIGHT AND THROUGH
SUNDAY AND SUNDAY NIGHT. A LIGHTER WIND PROFILE WILL TRANSITION TO
EASTERLY EARLY NEXT WEEK...MODERATING OUR TEMPERATURES CLOSER TO THE
SEASONAL AVERAGE. BY TUESDAY...THE LARGE AREA OF HIGH PRESSURE WILL
BE CENTERED IN THE WESTERN NORTH ATLANTIC AND MOISTURE VALUES BEGIN
TO REBOUND LOCALLY. A SLIGHT CHANCE OF SHOWERS WILL BE ADVERTISED
BEGINNING THEN. THE LATEST RUN OF THE GFS AND ECMWF SHOW MUCH DEEPER
MOISTURE RETURNING WEDNESDAY AND WEDNESDAY NIGHT WELL AHEAD OF A
TROUGH SWINGING INTO THE NORTHERN GULF. INCREASED OUR PROBABILITY OF
RAIN THEN...AND INSERTED A SLIGHT CHANCE FOR THUNDER AS INSTABILITY
INCREASES. A FRONT DROPS INTO THE SOUTHEASTERN GULF BY LATE THURSDAY
AND SHOULD BE PULLED THROUGH THE KEYS AND SURROUNDING WATER BY EARLY
FRIDAY MORNING. MID LEVEL RAIN CHANCES LATE THURSDAY DIMINISH TO JUST
A SLIGHT CHANCE THROUGH THE DURATION OF THE FORECAST. THE WARM
CONDITIONS THROUGH THE MIDDLE OF THE WORK WEEK WILL TRANSITION TO A
FEW DEGREES BELOW THE SEASONAL AVERAGE FOR FRIDAY AND SATURDAY.

&&

.MARINE...
WILL ALLOW THE GALE WARNING TO CONTINUE FOR AT LEAST A COUPLE MORE
HOURS...BUT A TRANSITION TO A SMALL CRAFT ADVISORY MOST LOCATIONS IS
EXPECTED FOR LATER THIS EVENING AND OVERNIGHT. RECREATIONAL BOATING
CONDITIONS WILL CONTINUE TO IMPROVE THROUGH SUNDAY AS HIGH PRESSURE
REACHES FURTHER DOWN THE FLORIDA PENINSULA AND OUR GRADIENT RELAXES.
BY MONDAY...A GENTLE WIND WILL SET IN FROM THE EAST. GENTLE TO
MODERATE WINDS WILL TRANSITION TUESDAY AND WEDNESDAY WELL AHEAD OF A
FRONT THAT PUSHES INTO THE SOUTHEASTERN GULF OF MEXICO BY THURSDAY.
SHOWER COVERAGE IS EXPECTED TO INCREASE WEDNESDAY AND WEDNESDAY NIGHT
WITH ISOLATED THUNDERSTORMS.

&&

.AVIATION...
UNTIL 12Z/24TH...WEST TO NORTHWEST SURFACE WINDS WILL
AVERAGE BETWEEN 18 AND 25 KNOTS WITH OCCASIONAL GUSTS OF AROUND 30
KNOTS FOR THE BALANCE OF THIS AFTERNOON...BEFORE SLACKENING TO 10 TO
15 KNOTS WITH GUSTS OF 20 TO 25 KNOTS BY EVENING. WINDS
WILL DECREASE LATE TONIGHT...WITH NORTHWEST TO NORTH WINDS OF 10
TO 15 KNOTS WITH OCCASIONAL GUSTS OF AROUND 20 KNOTS. VFR CEILINGS
OF 050-060 WILL PREVAIL AT THE KEY WEST TERMINAL...BUT CLOUD COVER
WILL ERODE TOWARD MORNING AT THE MARATHON AIRPORT.
