AREA FORECAST DISCUSSION FOR THE FLORIDA KEYS
NATIONAL WEATHER SERVICE KEY WEST FL
1018 AM EST WED JAN 29 2014

.DISCUSSION...
CURRENT WEATHER SUMMARY -- A HARD RAIN SWEPT FROM WEST TO EAST
THROUGH THE FLORIDA KEYS LATE LAST NIGHT AND EARLY THIS MORNING...
WITH RAINFALL MEASUREMENTS EXCEEDING ONE INCH IN SEVERAL
COMMUNITIES. THE RAINS WERE ASSOCIATED WITH RAPID DEVELOPMENT OF
NUMEROUS SHOWERS AND SCATTERED THUNDERSTORMS WITHIN A NORTHEAST TO
SOUTHWEST ZONE OF INCREASING BOUNDARY-LAYER MOISTURE CONVERGENCE
ALIGNED OVER THE FLORIDA KEYS. A COMPARISON OF DATA FROM RADIOSONDE
BALLOONS OVER THE LAST 24 HOURS SHOWS BOTH SIGNIFICANT WARMING IN THE
LOWER TROPOSPHERE AND SIGNIFICANT COOLING IN THE MID TROPOSPHERE...
LEADING TO DESTABILIZATION AND A SPIKE IN POTENTIAL BUOYANCY. THE
OVERNIGHT RAIN-COOLED LOW TEMPERATURES AVERAGED RIGHT AROUND 70F...
WHILE WINDS REMAINED MOSTLY LIGHT AND VARIABLE OR LIGHT SOUTH...
EXCEPT LOCALLY HIGHER AND GUSTY NEAR THUNDERSTORMS. CURRENTLY...A
THUNDERSTORM CLUSTER IS MOVING NORTHEASTWARD OVER THE WATERS JUST
SOUTH OF DRY TORTUGAS NATIONAL PARK...WHILE NUMEROUS SHOWERS ARE
MOVING WITHIN A SWATH OVER THE EXTREME SOUTHEASTERN GULF OF MEXICO.
MOSTLY RAIN-FREE CONDITIONS ARE OBSERVED ACROSS FLORIDA KEYS ISLAND
COMMUNITIES...HAWK CHANNEL...AND THE STRAITS OF FLORIDA.
HOWEVER...OPAQUE SKY COVER EQUALS OR EXCEEDS 50 PERCENT OVER MOST OF
THE AREA ALONG AND NORTH OF THE FLORIDA KEYS...WITH MOSTLY SUNNY
SKIES PREVAILING OVER MUCH OF THE STRAITS OF FLORIDA WHICH REMAIN
SOLIDLY IN THE WARM SECTOR. BOTH SATELLITE AND SURFACE OBSERVATIONS
SHOW AN APPROACHING COLD FRONT JUST NORTH OF THE FLORIDA KEYS. THE
PRECEDING ROPE CLOUD APPEARS TO BE WITHIN 50 MILES NORTHWEST OF DRY
TORTUGAS AND WITHIN 100 MILES OF KEY WEST...PER SATELLITE IMAGES.
MARITIME TROPICAL AIR HAS DEVELOPED OVER AND/OR ADVECTED ACROSS THE
FLORIDA KEYS AND ADJOINING COASTAL WATERS THIS MORNING...WITH CURRENT
AIR TEMPERATURES IN THE UPPER 70S AND DEWPOINTS IN THE LOW TO MID
70S.

AFTERNOON FORECAST HIGHLIGHTS -- THE WEATHER PATTERN FAVORS CONTINUED
LARGE-SCALE ASCENT OF WARM...MOIST AIR OVER THE FLORIDA KEYS THIS
AFTERNOON. THE APPROACHING COLD FRONT IS VERY SHALLOW AND IN A DECAY
STAGE...AND LIKELY WILL DECELERATE AND DISINTEGRATE AS IT LIMPS
THROUGH THE FLORIDA KEYS LATER TODAY. HOWEVER...AT THE SAME TIME...
THE FRONTAL ZONE WILL ONLY ADD TO A ZONE OF MOISTURE CONVERGENCE IN
PLACE OVER THE SOUTHERN FLORIDA PENINSULA AND SOUTHEASTERN GULF OF
MEXICO. DEVELOPMENT OF CONVECTION CELLS/SYSTEMS AND ASSOCIATED COLD
POOLS/OUTFLOWS LIKELY WILL PLAY HAVOC WITH THE AREA WIND FIELD LATER
TODAY AND PERHAPS LEAD TO AN EARLIER DE FACTO FRONTAL PASSAGE FROM
COOL OUTFLOW AS NEARBY CONVECTIVE COLD POOLS COALESCE WITH THE
APPROACHING SHALLOW CONTINENTAL AIR MASS.

WE WILL STAY THE COURSE WITH THE FORECAST FOR THIS AFTERNOON. BEST
CHANCE FOR ADDITIONAL MEASURABLE RAINFALL MAY IN FACT BE DURING THE
LATE AFTERNOON HOURS. HOWEVER...THE PROXIMITY OF MESOSCALE BOUNDARIES
AND THE APPROACHING FRONT MAY LEAD TO RAPID IN SITU DEVELOPMENT OF
SHOWERS/STORMS EARLIER.
&&

.MARINE...
A WEAKENING COLD FRONT WILL MOVE SOUTHWARD OVER THE EXTREME
SOUTHEASTERN GULF OF MEXICO AND SOUTHERN FLORIDA PENINSULA THIS
AFTERNOON...APPROACHING THE FLORIDA KEYS THIS EVENING. THE FRONT WILL
STALL NEAR THE FLORIDA KEYS WEDNESDAY AND THURSDAY. A HIGH PRESSURE
SYSTEM WILL SHIFT EASTWARD OVER THE SOUTHERN UNITED STATES FRIDAY
THROUGH SUNDAY.
&&

.AVIATION...
THROUGH 29/19Z...PREVAILING VFR CONDITIONS ARE EXPECTED AT BOTH EYW
AND MTH. FROM 29/19Z-29/24Z...SHORT-LIVED MVFR/IFR CIGS AND OR/VIS
WILL BE LIKELY ANY IN ANY SHOWERS AND THUNDERSTORMS THAT MANAGE TO
IMPACT EITHER OR BOTH ISLAND TERMINALS. AMENDMENTS WILL BE ISSUED AS
NECESSARY...BUT HAVE INSERTED VCTS IN TAF. ISOLATED WIND GUSTS NEAR
30 KNOTS ARE POSSIBLE IN AND NEAR SHOWERS OR STORMS. WINDS WILL SHIFT
NORTHERLY AS THE SURFACE FROPA IMPACTS THE TERMINALS....WITH WINDS
INCREASING TO 12-15KT AND GUSTS OF 20-25KT.
