AREA FORECAST DISCUSSION FOR THE FLORIDA KEYS
NATIONAL WEATHER SERVICE KEY WEST FL
240 PM EDT THU OCT 9 2014

.DISCUSSION...A LOW LEVEL ANTICYCLONE HAS DEVELOPED ACROSS THE
SOUTHEASTERN UNITED STATES...FAVORABLY DOWNSTREAM FROM AN UPPER LEVEL
RIDGE EMANATING FROM MEXICO. RIBBONS OF DRY AND MOIST AIR LAY UPSTREAM
OF THE FLORIDA KEYS...APPARENT ON AVAILABLE MIMIC TPW LOOPS OF THE
WESTERN NORTH ATLANTIC. THIS MORNING'S SOUNDING DESCRIBED AN EAST-
NORTHEASTERLY AND MOIST PROFILE THROUGH 700 MB...UNDERNEATH
WARMING...DRYING...AND LIGHTER WINDS. SIMILAR TO YESTERDAY...A SLOW
START TO DAYTIME HEATING. OPAQUE HIGHER CLOUDS CONTAINED ISLAND
TEMPERATURES IN THE LOWER 80S THROUGH MUCH OF THE MORNING. RECENT
VISIBLE SATELLITE SCANS PLACE THE ARC OF CIRRUS WELL SOUTH OF THE
ISLAND CHAIN...AND TEMPERATURES HAVE RESPONDED...REACHING WELL INTO
THE UPPER 80S.

.SHORT TERM (TONIGHT THROUGH SATURDAY NIGHT)...THE ANTICYCLONE TO OUR
NORTH WILL DRIFT EAST AND MAINTAIN ITS INTENSITY. EXPECT FRESH
NORTHEAST BREEZES TO PEAK AND LULL FOR THE NEXT FEW DAYS. RAIN
CHANCES WILL BE SLIGHT DUE TO SUBSIDENCE ABOVE THE BOUNDARY LAYER.
OVERNIGHT LOWS WILL BE A LITTLE ABOVE NORMAL...LOWER 80S...WHILE
DAYTIME HIGHS WILL BE NEAR NORMAL...UPPER 80S. LAND BREEZES MAY
RESULT IN CONFLUENT FLOW DURING THE OVERNIGHT HOURS WHILE DAYTIME
HEATING MAY RESULT IN DIFFLUENT FLOW...ASIDE FROM LEESIDE STREAMERS.
LONG STORY SHORT...PRECIPITATION WILL BE FAVORED NEAR DAWN ACROSS THE
ATLANTIC COASTAL WATERS...AND IN THE LEE OF ISLANDS DURING THE
AFTERNOONS.

&&

.LONG TERM (SUNDAY THROUGH THURSDAY)...A DEEP AND SHARP UPPER LEVEL
TROUGH WILL DIG INTO THE CENTRAL UNITED STATES SUNDAY AND
MONDAY...NUDGING THE LOW LEVEL ANTICYCLONE EAST INTO THE NORTH
ATLANTIC. THIS MUCH IS AGREED UPON. THE DEGREE AND MAGNITUDE OF
VEERING IN THE WIND PROFILE IS UNCERTAIN. FOR NOW...WE HAVE VEERED
THE TEXT PRODUCTS TO THE SOUTHEAST...WHEN IN FACT THEY MAY BOX ALL
THE WAY AROUND THE ROSE...WEDNESDAY THROUGH THURSDAY. SOUTHEASTERLIES
WERE CHOSEN BASED ON A BLEND OF ENSEMBLES AND DETERMINISTIC
SOLUTIONS.

&&

.MARINE...A HIGH PRESSURE SYSTEM CENTERED OVER THE WESTERN NORTH
ATLANTIC WILL SUPPORT FRESH NORTHEAST TO EAST BREEZES ACROSS FLORIDA
KEYS COASTAL WATERS. BREEZES MAY SLACKEN EARLY NEXT WEEK AS THE HIGH
PRESSES EAST INTO THE NORTH ATLANTIC.

&&

.AVIATION...ISOLATED SHOWERS AND A FEW THUNDERSTORMS ARE EXPECTED TO
FAVOR THE ATLANTIC WATERS THROUGH LATE THIS EVENING. THE OVERALL
PROBABILITY OF SUB-VFR CONDITIONS AT EITHER KEY WEST OR MARATHON
THROUGH THE ENTIRE FORECAST IS LOW ENOUGH TO KEEP THAT MENTION OUT OF
THE TAFS AT THIS TIME. EXPECT NORTHEAST WINDS BETWEEN 10 TO 15 KNOTS
AT BOTH LOCATIONS.

&&

.CLIMATE...ON THIS DATE IN KEYS WEATHER HISTORY...IN 1990...3.14
INCHES OF RAIN WAS RECORDED IN KEY WEST. THIS SET THE DAILY RAINFALL
RECORD FOR OCTOBER NINTH IN KEY WEST. RAINFALL RECORDS FOR KEY WEST
DATE BACK TO 1871.
