AREA FORECAST DISCUSSION FOR THE FLORIDA KEYS
NATIONAL WEATHER SERVICE KEY WEST FL
323 PM EDT MON MAY 30 2011

.DISCUSSION...
DURING THE COURSE OF THE DAY...SKIES HAVE RANGED FROM MOSTLY SUNNY
TO MOSTLY CLOUDY WITH ABOUT 35 PERCENT OF THE ISLAND CHAIN RECEIVING
AT LEAST A BRIEF SPELL OF RAINFALL...BUT RAINFALL AMOUNTS WERE
GENERALLY LESS THAN A TENTH OF AN INCH DUE TO FAST MOVING SHOWERS.
SURFACE WISE...A PERSISTENT WESTERN ATLANTIC RIDGE EXTENDS ACROSS
THE SOUTHEAST UNITED STATES...WITH TYPICAL LOWER PRESSURE IN THE
NORTHWEST CARIBBEAN SEA. ACROSS OUR MARINE DISTRICT...C-MAN STATION
PLATFORM OBSERVATIONS INDICATE MOSTLY EAST WINDS OF AROUND 15 KNOTS
WITH OCCASIONAL GUSTS TO 20 KNOTS.

.SHORT TERM (TONIGHT THROUGH THURSDAY)...
A DEEP TROPOSPHERIC ANTICYCLONE CENTERED OVER THE TENNESSEE AND OHIO
VALLEY WILL RELOCATE WESTWARD INTO THE SOUTHERN PLAINS...WHILE
EXPANDING EASTWARD ACROSS THE SOUTHEAST UNITED STATES. MEANWHILE...A
TROPICAL UPPER TROPOSPHERIC TROUGH (TUTT) LIKE FEATURE FROM THE
SOUTHWEST ATLANTIC OCEAN ACROSS THE BAHAMAS...AND INTO THE WESTERN
CARIBBEAN SEA WILL REMAIN FOR THE MOST PART SQUELCHED THROUGH THE
PERIOD. SURFACE WISE...A PERSISTENT WESTERN ATLANTIC RIDGE REACHING
ACROSS THE SOUTHEAST UNITED STATES WILL SLOWLY WEAKEN AND SAG
SOUTHWARD INTO THE NORTHER PORTION OF THE FLORIDA PENINSULA...WHILE
LOWERING PRESSURE IN THE WESTERN CARIBBEAN GRADUALLY TAKES PLACE.

PRECIPITATION WISE...WITH OUR REGION LYING ON THE SOUTHERN PERIPHERY
OF THE AFOREMENTIONED ANTICYCLONIC FLOW AND DEEP TROPICAL MOISTURE
HOLDING IN THE NORTHWEST CARIBBEAN SEA...PERIODIC AND SUBTLE LOW
LEVEL UNDULATIONS ASSOCIATED WITH SLIGHTLY HIGHER MOISTURE CONTENT
WILL MIGRATE THROUGH OUR SERVICE AREA OVER THE NEXT SEVERAL DAYS.
GIVEN TIMING ISSUES...WILL INSERT LOW CHANCE 30 PERCENT
POPS...REALIZING POPS MAY VARY FROM 10 TO 40 PERCENT ALONG THE
ISLAND CHAIN AT ANY GIVEN TIME. TEMPERATURE WISE...DESPITE BREEZY TO
OCCASIONAL WINDY CONDITIONS...STRONG INSOLATION WILL ALLOW HIGH
TEMPERATURES TO CLIMB INTO THE UPPER 80S WITH OVERNIGHT LOWS IN THE
UPPER 70S TO AROUND 80 DEGREES OUTSIDE OF A SIGNIFICANT DOWNPOUR.

&&

.LONG TERM (THURSDAY NIGHT THROUGH MONDAY)...
FORECAST UNCERTAINTY REMAINS HIGH DURING THE PERIOD...AS THE GFS
CONTINUES TO DELAY LIFTING THE DEEP TROPICAL MOISTURE (PWAT IN
EXCESS OF 2.0 INCHES) NORTHWARD INTO OUR REGION...WHILE ECMWF
REMAINS STEADFAST IN BLOCKING AND KEEPING THE RICH...MOIST TROPICAL
AIR SOUTH OF THE ARCHIPELAGO OF CUBA. GIVEN THE MASSIVE AND
VERY FORMIDABLE EAST-WEST ORIENTED ANTICYCLONE TO THE NORTH...WILL
LEAN TOWARD A GRADUAL INCREASE IN MOISTURE WITH ISOLATED
THUNDERSTORMS INCLUDED ALONG THE ISLAND CHAIN BEGINNING THURSDAY.
CONSIDERING THE PROLONGED DRY PATTERN IN OUR REGION...WILL MAINTAIN
LOW CHANCE POPS UNTIL FORECAST CONFIDENCE INCREASES. TEMPERATURE
WISE...DAYTIME HIGHS WILL AVERAGE IN THE UPPER 80S WITH OVERNIGHT
LOWS IN THE UPPER 70S TO NEAR 80 OUTSIDE OF RAINFALL.

&&

.MARINE...
WITH HIGH PRESSURE TO THE NORTH AND A TROUGH OF LOW PRESSURE
LINGERING IN THE NORTHWEST CARIBBEAN SEA...FRESH TO OCCASIONAL
