AREA FORECAST DISCUSSION FOR THE FLORIDA KEYS
NATIONAL WEATHER SERVICE KEY WEST FL
333 PM EST FRI DEC 14 2012

.DISCUSSION...
STRATUS CLOUDS HAVE PERSISTED FOR MUCH OF THE DAY OVER THE LOWER
FLORIDA KEYS...AND AT TIMES...PORTIONS OF THE MID/UPPER KEYS. THE
CLOUD COVER HAS KEPT AIR TEMPERATURES A LITTLE COOLER THAN INITIALLY
EXPECTED OVER THE LOWER KEYS. HIGH TEMPERATURES THUS FAR HAVE RANGED
FROM ABOUT 73F IN KEY WEST TO NEAR 80F IN KEY LARGO. THE FRONTAL
PASSAGE YESTERDAY WAS BY NO MEANS A CLEAN ONE. IN FACT...THE OLD
FRONTAL ZONE IS DISINTEGRATING PRETTY MUCH RIGHT OVER THE STRAITS OF
FLORIDA AT THIS MOMENT. A FEW THOUSAND FEET OFF THE GROUND...WINDS
ARE LIGHT OUT OF THE SOUTH...WITH SOME LAYERED LIFTING AND
CONDENSATION YIELDING STRATOCUMULUS CLOUD VARIETIES TO ADD TO THE
LOWER STRATUS. ISOLATED SHOWERS ARE CONCENTRATED ALONG A ROPE CLOUD
WHICH IS CENTERED OVER THE FLORIDA CURRENT/GULF STREAM IN THE STRAITS
OF FLORIDA. ALSO...A FEW RECENT SHOWERS HAVE FORMED OVER THE
EVERGLADES OWING TO SOUTH FLORIDA PENINSULAR HEATING AND CONVERGENCE
IN THE NORTHEASTERLY FLOW. THESE LOW-TOPPED CELLS NOW ARE DRIFTING
SOUTHWESTWARD OVER PORTIONS OF FLORIDA BAY AND THE EXTREME
SOUTHEASTERN GULF OF MEXICO.

WINDS HAVE LULLED A LITTLE THIS AFTERNOON FROM THEIR OVERNIGHT
SPEEDS. HOWEVER...AN EVENING SURGE LOOKS PROBABLE AS A SMALL-SCALE
PRESSURE PERTURBATION TRANSITS THE AREA. LOW TEMPERATURES TONIGHT
SHOULD BE SIMILAR TO LAST NIGHT...LIKELY ENDING UP IN THE UPPER 60S
AT MOST ISLAND LOCATIONS. A FEW SPRINKLES OR VERY LIGHT SHOWERS ARE
POSSIBLE THIS EVENING OVER THE KEYS. HOWEVER...CLOUD COVER IS
EXPECTED TO THIN OVERALL...AS LOW-LEVEL WINDS VEER...THE LOW STRATUS
DISSIPATES...AND CUMULUS AND STRATOCUMULUS BASES RISE.

THE OVERALL UPPER-AIR PATTERN ACROSS NORTH AMERICA WILL REMAIN
PROGRESSIVE FOR THE NEXT SEVERAL DAYS...WITH AT LEAST TWO SHORT
WAVES PROPAGATING EASTWARD WITHIN THE WESTERLIES. EACH OF THE SHORT-
WAVE TROUGHS WILL BE ASSOCIATED WITH A WEAK COLD FRONT AT THE
SURFACE. BOTH FRONTS ARE LIKELY TO REACH THE FLORIDA KEYS...ALTHOUGH
TIMING AND INTENSITY REMAIN UNCERTAIN. THE FIRST FRONT LOOKS LIKE IT
WILL BE IN THE VICINITY AROUND TUESDAY NIGHT...AND THE SECOND FRONT
MAY BE APPROACHING BY NEXT FRIDAY. EACH FRONT APPEARS TO BE SHALLOW
WITH LIMITED RETURN FLOW AND LARGE-SCALE FORCING FOR ASCENT...SIMILAR
TO THE LAST COUPLE OF FRONTS WE HAVE SEEN. THEREFORE...RAIN CHANCES
WILL REMAIN VERY LOW TO NIL FOR MOST OF THE NEXT SEVEN DAYS.
TEMPERATURES WILL FLIRT WITH DECEMBER AVERAGES...RISING A LITTLE OVER
THESE AVERAGES LEADING UP TO THE FRONTAL PASSAGES...AND DIPPING
SLIGHTLY BELOW THE AVERAGES FOLLOWING THEM.
&&

.MARINE...
SMALL CRAFT SHOULD EXERCISE CAUTION IN HAWK CHANNEL AND THE STRAITS
OF FLORIDA TONIGHT AS NORTHEASTERLY BREEZES SURGE TO 15-20 KNOTS.
SLACKENING BREEZES ARE PROBABLE FOR LATER TONIGHT INTO THE WEEKEND.
HOWEVER...SUSTAINED WINDS LIKELY WILL REMAIN ABOVE 10 KNOTS. WINDS
WILL BOX AROUND THE COMPASS...TURNING EASTERLY ON SUNDAY...SOUTHERLY
ON MONDAY...AND WESTERLY ON TUESDAY. A WEAK COLD FRONT LOOKS
INCREASINGLY LIKELY FOR TUESDAY NIGHT...FOLLOWED BY ANOTHER RAPID
POST-FRONTAL TRANSITION LATER IN THE WEEK.
&&

.AVIATION...
VFR CONDITIONS WILL PREVAIL OVERNIGHT AT THE ISLAND TERMINALS. BRIEF
MVFR CEILINGS WILL BE POSSIBLE AS PATCHES OF STRATOCUMULUS STREAM
SOUTHWESTWARD ACROSS THE AREA. SURFACE WINDS WILL BE 10 TO 15 KNOTS
THIS AFTERNOON...PICKING UP A FEW KNOTS WITH INCREASING GUSTS THIS
EVENING...THEN RELAX TOWARDS MORNING OUT OF THE EAST NORTHEAST.
