AREA FORECAST DISCUSSION FOR THE FLORIDA KEYS
NATIONAL WEATHER SERVICE KEY WEST FL
421 AM EST MON JAN 24 2011

.DISCUSSION...
.CURRENTLY...
CLOUDS HAVE INCREASED ACROSS THE SERVICE AREA DURING THE OVERNIGHT
HOURS...AND A FEW SPRINKLES OR POSSIBLE LIGHT SHOWERS HAVE DEVELOPED
ACROSS THE OFFSHORE WATERS WELL SOUTH OF THE LOWER KEYS DURING THE
PAST HOUR. WINDS VARY QUITE A BIT ACROSS THE AREA...WITH AN EASTERLY
SURGE BRINGING 15 TO 20 KNOT WINDS TO PARTS OF THE ATLANTIC WATERS...
WHILE PARTS OF THE GULF SIDE AND ISLAND CHAIN MAINTAIN A MUCH
LIGHTER NORTHEAST FLOW.

SURFACE ANALYSIS DEPICTS A SPRAWLING HIGH PRESSURE AREA CENTERED OVER
THE NORTHEASTERN UNITED STATES AND EXTENDING DOWN THE EASTERN
SEABOARD...WITH A LOW PRESSURE TROUGH DEVELOPING ALONG THE TEXAS
COAST. THE KEYS LIE WITHIN A MODERATE PRESSURE GRADIENT ALONG THE
SOUTHERN PERIPHERY OF THE HIGH. ALOFT...BROAD TROUGHING OVER THE
MIDWEST AND NORTHEAST IS ANCHORED BY A POLAR VORTEX OVER THE CANADIAN
MARITIMES...WITH SHORTWAVE ENERGY DIVING SOUTHWARD ALONG THE WESTERN
SIDE OF THE LONGWAVE TROUGH OVER THE ROCKIES. THE SUNDAY EVENING KEY
WEST SOUNDING REMAINED DRY AND STABLE...HOWEVER VEERING FLOW IN THE
LOW LEVELS WAS ALLOWING FOR INCREASING MOISTURE AND LIKELY SOME
SHALLOW ISENTROPIC LIFT BENEATH THE INVERSION.

.SHORT TERM (TODAY THROUGH WEDNESDAY)...
BENIGN WEATHER WILL CONTINUE ACROSS THE KEYS TODAY AND TONIGHT...
THEN GIVE WAY TO A MORE ACTIVE WEATHER PERIOD FOR TUESDAY THROUGH
WEDNESDAY. A PROGRESSIVE FLOW REGIME OVER THE CONUS WILL ALLOW HIGH
PRESSURE INITIALLY ALONG THE EASTERN SEABOARD TO SHIFT OFFSHORE TODAY
AND TONIGHT. LOW LEVEL WINDS ARE ALREADY VEERING ACROSS THE KEYS...
WITH INCREASING STRATOCU ACROSS THE ATLANTIC WATERS LIKELY INDICATIVE
OF ISENTROPIC LIFT BENEATH THE INVERSION. THUS EXPECT MOSTLY CLOUDY
CONDITIONS FOR THE NEXT 24 HOURS...ALTHOUGH CONTINUED STABLE
CONDITIONS WITH THE LOW LEVEL INVERSION REMAINING IN PLACE SHOULD
ALLOW FOR JUST ISOLATED SHOWERS. WILL MAINTAIN DIME POPS TODAY...
INCREASING TO 20 PERCENT TONIGHT. TEMPS TODAY WILL REBOUND TO JUST
SLIGHTLY BELOW NORMAL (HIGHS IN THE LOWER 70S)...WITH ONLY A FEW
DEGREES OF COOLING EXPECTED TONIGHT DUE TO CLOUD COVER AND INCREASING
EAST/SOUTHEAST WINDS.

TUESDAY THROUGH WEDNESDAY...CONFIDENCE IN THE EVOLUTION AND TIMING
OF THE LARGE SCALE PATTERN HAS INCREASED SOMEWHAT DUE TO BETTER
AGREEMENT AMONG THE VARIOUS FORECAST MODELS. A STRONG SHORTWAVE WILL
DIVE INTO TEXAS TUESDAY...THEN CUT OFF OVER THE LOWER MISSISSIPPI
VALLEY TUESDAY NIGHT...AND TRACK EASTWARD OVER THE SOUTHEASTERN
STATES ON WEDNESDAY. THE ASSOCIATED SURFACE LOW WILL TRACK EASTWARD
ALONG THE NORTHERN GULF COAST ON TUESDAY...PASSING ACROSS NORTH
FLORIDA OR SOUTH GEORGIA TUESDAY NIGHT...AND OFF THE CAROLINA COAST
ON WEDNESDAY. THE TRAILING COLD FRONT NOW APPEARS LIKELY TO PASS
THROUGH THE KEYS WEDNESDAY MORNING...WITH A POSSIBLE PRE-FRONTAL
TROUGH LATE TUESDAY NIGHT. DEEP MOISTURE APPEARS LIKELY TO BE DRAWN
NORTHWARD INTO THE KEYS AHEAD OF THIS FRONT...ALONG WITH AN AXIS OF
MODERATE INSTABILITY. STRONG LOWER/MID LEVEL WIND FIELDS AND A NICELY
VEERING VERTICAL WIND PROFILE WOULD ALLOW FOR THE POSSIBILITY OF A
FEW STRONG OR EVEN ISOLATED SEVERE THUNDERSTORMS LATE TUESDAY NIGHT
INTO WEDNESDAY MORNING. MID/UPPER LEVEL SUPPORT APPEARS TO BE PRESENT
AS WELL...WITH THE LATEST GFS RUN DEPICTING RATHER IMPRESSIVE DEEP
LIFT ACROSS OUR AREA LATE TUE NIGHT INTO WED MORNING AS STRONG
MID/UPPER LEVEL JET STREAKS TRANSLATE ACROSS THE FLORIDA PENINSULA.
MUCH OF THE FLORIDA PENINSULA HAS BEEN PLACED INTO SLIGHT RISK OF
SEVERE BY SPC FOR THAT PERIOD...WITH THE KEYS LYING JUST SOUTH OF THE
OFFICIAL SLIGHT RISK AREA. WILL CONTINUE WITH CHANCE POPS FOR TUE
AFTERNOON...THEN INCREASE TO LIKELY POPS FOR TUE NIGHT...BEFORE
TRAILING POPS OFF ONCE AGAIN ON WEDNESDAY. TEMPS WILL WARM TO A FEW
DEGREES ABOVE NORMAL TUESDAY...THEN START TO COOL OFF WEDNESDAY WITH
DAILY HIGHS LIKELY OCCURRING DURING THE MORNING HOURS DUE TO THE
FRONTAL PASSAGE.

&&

.LONG TERM (WEDNESDAY NIGHT THROUGH SUNDAY)...
LONGWAVE TROUGHING OVER THE EASTERN CONUS SHOULD PROVIDE AN EXTENDED
PERIOD OF COOL AND DRY WEATHER ACROSS THE KEYS THROUGH THE LONG TERM
PERIOD. EXPECT DECREASING CLOUDINESS WED NIGHT...FOLLOWED BY MOSTLY
CLEAR CONDITIONS THU AND THU NIGHT IN THE WAKE OF THE COLD FRONT. THE
LATEST ECMWF REMAINS SOMEWHAT MORE AMPLIFIED THAN THE OTHER GUIDANCE
WITH A SHORTWAVE SWINGING THROUGH FLORIDA ON FRIDAY...BUT EVEN THE
EC HAS BACKED OFF FROM EARLIER RUNS WITH THIS FEATURE. AT THIS POINT
EXPECT NOTHING MORE THAN AN INCREASE IN HIGH CLOUDS...WITH NO POPS
MENTIONED THROUGHOUT THE LONG TERM. TEMPERATURES WILL REMAIN BELOW
NORMAL...WITH THE COOLEST READINGS EXPECTED THU/FRI WHEN HIGHS WILL
ONLY REACH THE UPPER 60S. THE WEEKEND WILL SEE SLIGHTLY WARMER
TEMPS...BUT STILL BELOW NORMAL WITH HIGHS ONLY AROUND 70 DEGREES.
LOWS WILL BE COOL...BUT NOT AS CHILLY AS WE HAVE SEEN PREVIOUSLY THIS
WINTER...MAINLY DROPPING INTO THE MID TO UPPER 50S.

&&

.MARINE...
AN EASTERLY WIND SURGE IS AFFECTING THE ATLANTIC WATERS...WITH C-MAN
OBS AND A LATE EVENING ASCAT PASS SHOWING WINDS IN THE 15 TO 20 KNOT
RANGE...AND A FEW SHIP REPORTS ESTIMATING EVEN STRONGER WINDS AT
DECK LEVEL. MEANWHILE..THE ASCAT DATA AND EXTRAPOLATION FROM THE FEW
AVAILABLE OBS INDICATE CONSIDERABLY LIGHTER NORTHEAST TO EAST WINDS
OVER THE COOLER GULF WATERS. THESE SURGES ARE OFTEN DIFFICULT TO
FORECAST...BUT IT APPEARS THAT CAUTION LEVEL WINDS OF 15-20 KNOTS
SHOULD PERSIST ACROSS THE ATLANTIC WATERS TODAY. TONIGHT...AS LOW
PRESSURE DEVELOPS OVER THE NORTHWESTERN GULF...AT LEAST CAUTION
CONDITIONS APPEAR LIKELY...WITH A GOOD CHANCE FOR SMALL CRAFT
ADVISORIES ON THE ATLANTIC SIDE. CAUTION OR ADVISORY CONDITIONS
SHOULD CONTINUE TUESDAY AND TUESDAY NIGHT...AS WINDS GRADUALLY VEER
AROUND TO THE SOUTHEAST THEN SOUTH AS THE LOW AND ASSOCIATED COLD
FRONT TRACK EASTWARD ACROSS THE GULF. STRONG THUNDERSTORMS WILL BE
POSSIBLE TUESDAY NIGHT INTO WEDNESDAY MORNING AS THE COLD FRONT MOVES
THROUGH OUR AREA. WINDS WILL THEN SHIFT TO THE NORTHWEST BEHIND THE
FRONT...WITH CAUTION OR ADVISORY CONDITIONS LIKELY CONTINUING AT
LEAST THROUGH WEDNESDAY EVENING. MODERATE NORTHERLY FLOW SHOULD THEN
PREVAIL FROM THURSDAY THROUGH THE END OF THE WEEK.

&&

.AVIATION...
A SCATTERED TO BROKEN DECK OF STRATOCUMULUS ACROSS THE FLORIDA
STRAITS WILL CONTINUE SPREADING NORTHWESTWARD ACROSS THE FLORIDA
KEYS TODAY. VFR CONDITIONS WILL HOWEVER PREVAIL...WITH BASES BETWEEN
3500 TO 6000 FT...WITH TOPS AROUND 6000 FT. SURFACE WINDS WILL BE
NORTHEAST AT 5 TO 10 KNOTS AND GUSTY THIS MORNING...INCREASING TO 10
TO 15 KNOTS AND GUSTY THROUGH TODAY. WINDS ARE EXPECTED TO INCREASE
FURTHER THIS EVENING TO AROUND 15 KNOTS.
