AREA FORECAST DISCUSSION FOR THE FLORIDA KEYS
NATIONAL WEATHER SERVICE KEY WEST FL
254 PM EDT THU JUN 2 2011

.DISCUSSION...
SHOWERS HAVE REMAINED SCATTERED EARLY THIS AFTERNOON IN THE OFFSHORE
WATERS SOUTH AND SOUTHWEST OF THE LOWER AND MIDDLE KEYS. A FEW
THUNDERSTORMS HAVE BEEN EMBEDDED WITHIN THIS LINE. ASIDE FROM A THIN
LINE OF SHALLOW CUMULUS EXTENDING OFF THE LOWER KEYS...SKIES ARE
MOSTLY SUNNY. TEMPERATURES ARE IN THE UPPER 80S...BUT DEWPOINTS HAVE
EASED DOWNWARD INTO THE 60S FROM EARLIER TODAY ALONG THE ISLAND CHAIN.
WINDS REMAIN MOSTLY FRESH FROM THE NORTHEAST/EAST AT ALL REPORTING
SENSORS...AND GUSTY OUT OVER OUR COASTAL WATERS.

DEEP RIDGING IN THE MID TO UPPER LEVELS WILL CONTINUE OVER THE SOUTHEAST
STATES AND WESTWARD TOWARD THE LOWER MS VALLEY OVER THE NEXT COUPLE
OF DAYS. SURFACE HIGH PRESSURE REBUILDING OVER NORTH FLORIDA AND THE
SOUTHEAST COAST WILL REMAIN THE DOMINANT WEATHER FEATURE THROUGH THE
WEEKEND...WITH LOWER PRESSURE IN THE WESTERN CARIBBEAN MOVING VERY
LITTLE. AS A RESULT...WE CAN EXPECT BREEZY CONDITIONS FROM NOW
THROUGH THE WEEKEND. RAIN CHANCES WILL BE TRIMMED OVER THE NEXT
COUPLE OF DAYS FOR THE KEYS AND SURROUNDING WATERS THANKS TO AN
INTRUSION OF DRIER AIR ALOFT FROM THE EAST/NORTHEAST AND MINOR
STABILIZATION IN THE MID LAYERS. THIS WILL KEEP POPS AT A SLIGHT
CHANCE THROUGH THE WEEKEND.

BY EARLY NEXT WEEK...A LOW AMPLITUDE TROUGH WILL DAMPEN THE RIDGE
ACROSS THE SOUTHEAST STATES AND WEAKEN THE SURFACE HIGH PRESSURE
WHILE SHIFTING IT SOUTHWARD CLOSER TO THE KEYS. WINDS ARE EXPECTED TO
DROP OFF SIGNIFICANTLY THEN. BROADER BUT MUCH WEAKER HIGH PRESSURE
TAKES SHAPE TO OUR NORTH THROUGH THE MIDDLE OF NEXT WEEK...AND
GRAPHICAL GUIDANCE SUGGESTS THAT LOW PRESSURE IN THE CARIBBEAN BEGINS
TO REACH NORTHEASTWARD. HOWEVER...DEEP MOISTURE REMAINS SHUNTED WELL
TO THE SOUTH AND SOUTHEAST OF OUR SERVICE AREA. WILL MAINTAIN A
RELATIVELY LOW POPS ADVERTISED THROUGH THE MIDDLE AND LATE PORTIONS
OF THE UPCOMING FORECAST...WITH TEMPERATURES AT OR SLIGHTLY ABOVE THE
SEASONAL AVERAGES.

&&

.MARINE...
EXPECT FRESH TO BRIEFLY STRONG WINDS OVER THE ENTIRE MARINE SERVICE
AREA TONIGHT THROUGH AT LEAST SUNDAY THANKS TO THE ORIENTATION OF THE
STRONG HIGH PRESSURE TO OUR NORTH AND STEADY LOW PRESSURE IN THE
WESTERN CARIBBEAN. AN EXERCISE CAUTION FOR SMALL CRAFT WILL REMAIN
HEADLINED IN EACH MARINE GROUPING TONIGHT THROUGH AT LEAST SUNDAY.
THERE IS THE PROBABILITY OF A SMALL CRAFT ADVISORY FOR LATE FRIDAY
THROUGH EARLY SATURDAY MORNING IN THE ATLANTIC WATERS AS A SURGE IS
EXPECTED THEN. EITHER WAY...HIGHER SEAS CAN BE EXPECTED THANKS TO THE
DURATION OF THE FRESH TO OCCASIONALLY STRONG NORTHEAST/EAST BREEZES
THAT HAVE BEEN AND WILL REMAIN IN PLACE. TAKE THIS INTO CONSIDERATION
IF YOU PLAN ANY BOATING IN THE WATERS SURROUNDING THE FLORIDA KEYS
THIS WEEKEND. MORE AGREEABLE RECREATIONAL BOATING IS ON TAP EARLY
NEXT WEEK AS WEAKER HIGH PRESSURE SETTLES CLOSER TO SOUTH FLORIDA AND
THE KEYS.

&&

.AVIATION...
OVERNIGHT...THE COMBINATION OF LOW PRESSURE IN THE WESTERN CARIBBEAN
AND SURFACE RIDGING ACROSS THE FLORIDA PENINSULA WILL RESULT
SUSTAINED EAST WINDS AVERAGING 12 TO 15 KNOTS WITH GUSTS IN EXCESS
OF 20 KNOTS. ONLY ISOLATED SHOWERS ARE EXPECTED TO IMPACT THE KEYS
TERMINALS WITH SHORT LIVED REDUCTIONS IN BOTH CIGS AND/OR VIS.
