AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KEY WEST FL
1045 AM EST SAT DEC 12 2015

.DISCUSSION...
A METEOROLOGICAL ANALYSIS THIS MORNING REVEALS A DEEP LAYER MEAN
ANTICYCLONE CENTERED OVER THE EASTERN GULF OF MEXICO BASIN AND
FLORIDA PENINSULA...WITH PREVAILING LARGE-SCALE SUBSIDENCE. DATA FROM
THE KEY WEST MORNING RADIOSONDE BALLOON INDICATED FURTHER
TROPOSPHERIC DRYING AS WELL. IN FACT...THE TOTAL PRECIPITABLE WATER
VALUE OF 1.02 INCHES IS THE LOWEST MEASURED SINCE NOVEMBER 28.

KEYS WITH JUST A FEW SHALLOW CUMULUS AND STRATOCUMULUS VARIETIES
OBSERVED. AIR TEMPERATURES IN MOST ISLAND COMMUNITIES ARE IN THE
UPPER 70S...WITH DEWPOINT TEMPERATURES IN THE LOWER 70S. THERMAL AND
MOISTURE CONDITIONS REMAIN ABOVE AVERAGE IN A PERSISTENT MARITIME
TROPICAL AIR MASS. A SURFACE HIGH PRESSURE AREA OVER THE WESTERN
NORTH ATLANTIC IS INTENSIFYING AS A WEAKENING TROUGH OVER THE
NORTHERN BAHAMAS MOVES WESTWARD. THUS...NORTHEAST TO EAST BREEZES ARE
FRESHENING ACROSS KEYS COASTAL WATERS WITH BUILDING SEAS. THE
FORECASTS ARE ON TRACK AT THIS POINT...AND MORNING UPDATES ARE

WATERS AS EAST BREEZES FRESHEN THIS AFTERNOON. A SMALL CRAFT ADVISORY

AND TONIGHT...RESULTING IN FRESHENING EASTERLY BREEZES ACROSS FLORIDA
KEYS COASTAL WATERS. MEANWHILE...A TROUGH CURRENTLY OVER THE NORTHERN
BAHAMAS WILL WEAKEN AS IT MOVES WESTWARD THROUGH THE FLORIDA KEYS ON
SUNDAY. THEREAFTER...THE HIGH PRESSURE AREA OVER THE WESTERN NORTH
ATLANTIC WILL WEAKEN MONDAY THROUGH WEDNESDAY...RESULTING IN GENTLE
TO MODERATE MOSTLY SOUTHEASTERLY BREEZES ACROSS KEYS COASTAL WATERS.
&&

.AVIATION...
VFR CONDITIONS WILL PREVAIL ACROSS BOTH ISLAND TERMINALS TODAY...
WITH A FEW CLOUDS AND DRY WEATHER IN THE FORECAST. WINDS WILL BECOME
A MODERATE BREEZE BY MIDDAY...VEERING TO MORE OF AN EASTERLY
COMPONENT...AND GUSTING TO AROUND 20 KNOTS.
&&

.CLIMATE...
MONTH TO DATE...KEY WEST INTERNATIONAL AIRPORT HAS RECEIVED 4.13
INCHES OF RAINFALL...ECLIPSING THE NORMAL DECEMBER MONTHLY RAINFALL
BY 1.91 INCHES. IN FACT...THE NORMAL RAINFALL FOR THE ENTIRE
METEOROLOGICAL WINTER...DECEMBER THROUGH FEBRUARY...IS JUST 5.75
INCHES. HISTORICALLY DURING STRONG EL NINO EVENTS...AS IS THE CURRENT
