AREA FORECAST DISCUSSION FOR THE FLORIDA KEYS
NATIONAL WEATHER SERVICE KEY WEST FL
314 PM EST SUN DEC 11 2011

.DISCUSSION...
WIDELY SPACED AND RELATIVELY SMALL SHOWERS PERSIST ON KBYX DOPPLER
RADAR EARLY THIS AFTERNOON. THE CURRENT ECHOES ARE HUGGING THE LOWER
AND MIDDLE KEYS...AND ADDITIONAL PATCHES ARE TRAVERSING THE GULF
WATERS BEYOND 20 NM FROM MAINLAND MONROE COUNTY...AND THE ATLANTIC
WATERS WELL SOUTH OF THE LOWER AND MIDDLE KEYS. AWAY FROM THESE FEW
SHOWERS...SKIES ARE PARTLY CLOUDY IN THE KEYS SERVICE AREA. TEMPERATURES
RANGE FROM 75 TO 80 DEGREES ALONG THE ISLAND CHAIN. WINDS ARE
NORTHEAST...AROUND 10 MPH ALONG THE ISLAND CHAIN...BETWEEN 10 AND 15
KNOTS IN THE BAY AND GULF WATERS...AND MORE CONSISTENTLY BETWEEN 15
AND 20 KNOTS OVER THE ATLANTIC AND FAR WESTERN GULF WATERS.

AN INITIAL LOW AMPLITUDE TROUGH WILL MOVE EAST OF THE EAST COAST
TONIGHT WHILE A SECONDARY AND SLIGHTLY STRONGER TROUGH MOVES THROUGH
THE SOUTHEAST AND MID ATLANTIC COAST THROUGH MONDAY. AT THE
SURFACE...AN APPENDAGE OF THE LARGE EAST COAST HIGH PRESSURE
SEPARATES EASTWARD INTO THE ATLANTIC OVERNIGHT. THE MAIN AREA OF HIGH
PRESSURE REMAINS ROOTED CLOSE TO THE EAST COAST WITH AN EXTENSION
INTO THE DEEP SOUTH...AND RESTRENGTHENS THROUGH EARLY WEDNESDAY. THE LOCAL
AREA WILL SEE A PERSISTENT NORTHEAST TO EAST BREEZE THROUGH 5 TO 8
KFT THROUGH THE NEXT 36 HOURS OR SO. BY EARLY TUESDAY...A
STRENGTHENING MID TO UPPER LEVEL RIDGE TAKES SHAPE ACROSS FLORIDA AND
THE SOUTHEAST REGION. THIS RIDGING REMAINS DOMINANT THROUGH THE
DURATION OF THE FORECAST. THE FLOW WILL REMAIN FRESH TO OCCASIONALLY
STRONG ON THE SOUTHERN PERIPHERY OF THE LARGE HIGH SURFACE PRESSURE.
THERE WILL PROBABLY BE VERY SMALL SHOWERS OR SPRINKLES THROUGH THE
LATE PERIODS OF THE FORECAST...BUT ON THE UPCOMING ZONE
FORECAST...PLAN TO ONLY ADVERTISE A SLIGHT CHANCE OF MEASURABLE RAIN
THROUGH LATE MONDAY NIGHT. FROM TUESDAY THROUGH NEXT WEEKEND...WILL
KEEP ANY MENTION OF MEASURABLE RAIN OUT ON THIS FORECAST.
TEMPERATURES WILL BE A FEW DEGREES ABOVE SEASONAL AVERAGE...ESPECIALLY
FROM TUESDAY THROUGH NEXT WEEKEND.

&&

.MARINE...
THE LATEST ASCAT IMAGE SHOWS 15 TO 20 KNOT WINDS REMAIN ACROSS THE
WESTERN-MOST GULF WATERS...JUST LIKE ACROSS ALL ATLANTIC WATERS. LESS
MIXING IS EXPECTED TO CONTINUE ACROSS THE BAY AND GULF WATERS BEYOND
20 NM FROM MAINLAND MONROE. WILL MAINTAIN AN EXERCISE CAUTION FOR
SMALL CRAFT IN THE ATLANTIC AND FAR WESTERN GULF WATERS ON THE
UPCOMING ISSUANCE FOR TONIGHT AND MONDAY. WINDS ARE EXPECTED TO SURGE
ON TUESDAY AS THE HIGH PRESSURE TO THE NORTH RE-STRENGTHENS. SMALL
CRAFT ADVISORY CONDITIONS ARE POSSIBLE IN THE ATLANTIC WATERS
BEGINNING THEN AND CONTINUING THROUGH THURSDAY. AN EXERCISE CAUTION
IS PROBABLE FOR ALL OTHER WATERS DURING THOSE PERIODS.

&&

.AVIATION...
VFR CONDITIONS EXPECTED AT THE KEY WEST AND MARATHON ISLAND
TERMINALS THROUGH MONDAY MORNING. NORTHEAST TO EAST SURFACE WINDS
NEAT 10 KNOTS WITH GUSTS OF 15 TO 20 KNOTS. SHORT LIVED FEW TO
SCATTERED CLOUDS WITH THE LOWEST LEVEL AOA 025 FEET WILL PASS THE
ISLAND TERMINALS AT TIMES. THERE IS A POSSIBILITY THAT VERY BRIEF
PERIODS OF MVFR DUE TO A PASSING SHOWER WITH LITTLE IMPACT TO FLIGHT
OPERATIONS.

&&

.CLIMATE...
KEYS WEATHER DATELINE...1936...THE LOW TEMPERATURE IN KEY WEST WAS
50 DEGREES. THIS SET THE DAILY RECORD MINIMUM TEMPERATURE ON DECEMBER
ELEVENTH...WHICH STANDS 75 YEARS LATER.
