AREA FORECAST DISCUSSION FOR THE FLORIDA KEYS
NATIONAL WEATHER SERVICE KEY WEST FL
1135 AM EST SAT FEB 16 2013

.DISCUSSION...
.CURRENTLY...KBYX SHOWS THAT MOST OF THE CWA IS CLEAR OF
PRECIPITATION AT THIS TIME. A FEW SHOWERS ARE FOUND SOUTH OF THE
FLORIDA STRAITS COASTAL WATERS ZONE...AND A FEW FALSE ECHOS ARE
VISIBLE NORTH OF THE ISLAND CHAIN. CMAN WINDS HAVE YET TO
INCREASE APPRECIABLY...AND ARE GENERALLY IN THE 10 TO 15 KNOT RANGE
WITH HIGHER WINDS...GUSTING TO 20 KNOTS...OVER THE GULF OF MEXICO.
MORNING KEY SOUNDING CAME IN WITH A THERMODYNAMIC PROFILE THAT IS
LARGELY UNCHANGED FROM 24 HOURS AGO. PWAT WAS 1.66 INCHES WHICH IS
AROUND 150 PERCENT OF NORMAL FOR THIS TIME OF THE YEAR. LOW LEVEL JET
WAS ALSO STILL APPARENT ABOVE 925 MB. WHILE MOISTURE AND INSTABILITY
ARE AVAILABLE...MOST OF THE DYNAMIC LIFT HAS PUSHED SOUTHEAST OF THE
AREA...THEREBY LEAVING THE AREA WITHOUT ANY CONVECTIVE TRIGGER.

.SHORT TERM...
WHILE A FEW SHOWERS CANNOT BE RULED OUT IN THE POST FRONTAL
ENVIRONMENT...POPS ARE SIGNIFICANTLY LOWER THAN YESTERDAY. THE BIG
STORY OF THE DAY WILL RESIDE IN THE STRONG WINDS THAT ARE SET TO
IMPACT BOTH THE LAND AND MARINE ZONES BEGINNING THIS AFTERNOON. WINDS
WILL GRADUALLY RAMP THROUGH TONIGHT ACROSS THE AREA RATHER THAN
SURGING IN A RAPID FASHION AS A PASSING FRONT WOULD. OVER
LAND...SUSTAINED WINDS SHOULD MAX OUT AROUND 25 MPH...THOUGH HIGHER
GUSTS TO 30 ARE POSSIBLE. THESE NUMBERS HAVE US FALLING JUST BELOW
OUR CRITERIA FOR A WIND ADVISORY...BUT THIS POSSIBILITY WILL BE RE-
EXAMINED THIS AFTERNOON. AS WINDS TURN NORTHEASTERLY TOMORROW
MORNING...THEY WILL INTRODUCE A CONTINENTAL AIR MASS TO THE ISLAND
CHAIN FROM THE MAINLAND WHICH SHOULD KEEP THE AREA IN THE CHILLER FOR
MOST OF THE DAY. TIMING OF LOWEST TEMPERATURES FOR SUNDAY SHOULD
COINCIDE WITH THIS WIND SHIFT AND WILL LIKELY BE IN THE MID MORNING
TO EARLY AFTERNOON TIME PERIOD. LOWEST TEMPS WILL BE FOUND IN THE
UPPER KEYS...WHERE WE SHOULD ONLY SINK TO NEAR 50 DEGREES. THIS
SHOULD KEEP US FROM SIGNIFICANT CONCERN ABOUT WIND CHILLS OR OTHER
WINTERTIME WEATHER CRITERIA...BUT MAKE NO MISTAKE...IT WILL BE A
CHILLY OVERNIGHT FOR SENSITIVE ANIMALS AND PLANTS. POPS THROUGH SUNDAY
SHOULD REMAIN MINIMAL AS EXCESSIVELY DRY MIDLEVEL AIR WILL IMPEDE ANY
DEEP CONVECTION. WITH STRONG LOW LEVEL INSTABILITY AND INCREASED
MOISTURE FLUX OFF OF WARM WATERS IN A BRISK WIND ENVIRONMENT... A FEW
SPRINKLES CANNOT BE RULED OUT IN THE NOCTURNAL ENVIRONMENT. STARTING
EARLY NEXT WEEK...A GRADUAL WARM UP SHOULD RETURN US TO CLIMATOLOGICAL
LEVELS.

&&

.MARINE...
THE STRONGEST WINDS SHOULD IMPACT THE GULF WATERS BEGINNING AFTER 21Z
TODAY...AND SHOULD GRADUALLY SPREAD SOUTHEAST THROUGH THE OVERNIGHT
HOURS TONIGHT. A NORTHWESTERLY SWELL WILL ACCOMPANY THIS WIND SURGE
AND WILL MOSTLY AFFECT THE WESTERN ZONES OF THE GULF AND FLORIDA
STRAITS. SEAS IN THE NORTHWESTERLY SWELL SHOULD MAX OUT AROUND 12
FEET. DURING THE DAYTIME TOMORROW...THE RESIDUAL SWELL WILL COMING
IN THE WESTERN STRAITS WITH A LOCALIZED NORTHEASTERLY WIND SWELL TO
CREATE AN AGITATED AND HIGHLY CONFUSED SEA STATE.

&&

.AVIATION...
THROUGH 00Z/17TH...VFR CONDITIONS WILL PREVAIL AT THE KEY WEST AND
MARATHON TERMINALS. THE MAIN WEATHER CONCERN WILL BE STRONG
NORTHWEST WINDS AND RESULTING SIGNIFICANT CROSSWINDS. EXPECT
NORTHWEST WINDS TO INCREASE DURING THE AFTERNOON TO BETWEEN 15 AND
20 KNOTS SUSTAINED WITH GUSTS OF 20 TO 25 KNOTS...BEFORE INCREASING
FURTHER THIS EVENING.

&&

.KEY WATCHES/WARNINGS/ADVISORIES...
FL...NONE.
GM...SMALL CRAFT ADVISORY UNTIL 5 AM EST SUNDAY FOR GMZ031>034-042>044-
     052>055-072>075.
