AREA FORECAST DISCUSSION FOR THE FLORIDA KEYS
NATIONAL WEATHER SERVICE KEY WEST FL
316 PM EST WED JAN 15 2014

.DISCUSSION...
.CURRENTLY...
AFTER A GRADUAL SURGE IN WINDS HAS EXITED THE ISLAND CHAIN TO OUR
SOUTHWEST...SUSTAINED ARE NORTH-NORTHWESTERLY WINDS ARE GENERALLY IN
THE 15 TO 20 KNOT RANGE SOUTH OF THE ISLAND CHAIN AND AROUND 15 KNOTS
ACROSS THE GULF WATERS. LIGHT RAIN AND A FEW HEAVIER SHOWERS HAVE BEEN
CONFINED TO THE OUTER WATERS OF MAINLAND MONROE AND THE WESTERN
STRAITS OF FLORIDA THUS FAR TODAY. TEMPERATURES HAVE HOVERED AROUND
70 THUS FAR TODAY WITH A GRADUAL DECREASE IN TEMPS EXPECTED THROUGH
THE REMAINDER OF THE AFTERNOON AND EVENING HOURS ON THE STRENGTH OF
COLD ADVECTION FROM THE NORTH.

.SHORT TERM...
ONLY MINOR CHANGES IN THE SHORT TERM PERIOD OF THE FORECAST THIS
CYCLE. WITH CURRENT SATELLITE AND RADAR TRENDS...EXPECT THAT A
FORECAST ON THE HIGH SIDE OF CURRENT MOS GUIDANCE POP VALUES FOR
TONIGHT IS APPROPRIATE. ISENTROPIC LIFT HAS BEEN VARIABLE ACROSS THE
WESTERN WATERS THROUGH TODAY...AND HAS BEEN VERY POORLY HANDLED BY
THE MODELS. EXPECT THAT HEAVIER SHOWERS THAT ARE CURRENTLY VISIBLE
OVER CUBA SHOULD REMAIN LOCKED TO THAT LAND MASS OR SHORT LIVED ON
THE NORTH SIDE IN WEST-NORTHWESTERLY MIDLEVEL FLOW...WHILE A
TRANSITIONING MIDLEVEL WESTERLY FLOW WILL USHER IN DEEP MOISTURE IN
THE MID AND UPPER LEVELS. A FORECASTED LOW LEVEL DRY POCKET SHOULD
LIMIT ANY SIGNIFICANT SHOWER ACTIVITY THAT WOULD OTHERWISE REACH THE
GROUND TONIGHT...BUT A STRAY LIGHT SHOWER OR SPRINKLE CANNOT BE RULED
OUT. HAVE ALSO EXTENDED THE FORECASTED SLIGHT RAIN CHANCE PERIOD
THROUGH THE DURATION OF THE OVERNIGHT PERIOD. OWING TO SIGNIFICANT
UNCERTAINTY EVEN IN THE SHORT RANGE HIGH-RES MODELS.

LATE IN THE OVERNIGHT PERIOD...A SECONDARY SURFACE FRONT WILL RAPIDLY
SWEEP ACROSS THE SOUTHWEST GULF OF MEXICO...BRINGING A WINDY TIME
PERIOD TO THE KEYS THROUGH EARLY THURSDAY. BEHIND THIS
FRONT... NORTH TO NORTHEASTERLY WINDS WILL ADVECT POSSIBLY THE
COLDEST AIR OF THE SEASON ACROSS THE ISLAND CHAIN WITH PORTIONS OF
THE UPPER KEYS BOTTOMING OUT IN THE UPPER 40S...WITH BREEZY WINDS AND
MOSTLY CLEAR SKIES TAKING HOLD.

.LONG TERM...
EXPANSIVE RIDGING OVER THE GULF OF MEXICO...AND CONSEQUENTLY LIGHT TO
MODERATE NORTHERLY LOW LEVEL WINDS WILL CONTINUE TO DOMINATE THE
SYNOPTIC PATTERN FROM LATE FRIDAY THROUGH AT LEAST TUESDAY. THIS WILL
COMBINE WITH A PERSISTENTLY DRY MID AND UPPER LEVEL PROFILE TO
PROVIDE AN EXTENDED PERIOD OF UNSEASONABLY COOL TEMPERATURES AND
MOSTLY CLEAR SKIES. THE NEXT FRONTAL BOUNDARY THAT IS EXPECTED TO
WAVE THROUGH THE AREA IS PROGGED TO IMPACT THE KEYS ON LATE TUESDAY
OR EARLY WEDNESDAY. AHEAD OF THIS FRONT...CORRESPONDING NOTCHED
TEMPERATURES AND POPS UP A BIT ON TUESDAY NIGHT... AND INCREASED
CLOUD COVER OVER THE ISLANDS FOR TUESDAY OVERNIGHT INTO WEDNESDAY. NO
OTHER SIGNIFICANT CHANGES ARE EXPECTED FOR THIS AFTERNOONS FORECAST
PACKAGE.

&&

.MARINE...
NORTHWESTERLY WINDS WILL RAPIDLY INCREASE OVERNIGHT TONIGHT AFTER
MIDNIGHT ACROSS ALL WATERS...WITH THE STRONGEST WINDS EXPECTED TO BE
IN THE 20 TO 25 KNOT RANGE. THIS IS SLIGHTLY LESS INTENSE THAN
PREVIOUS WINDS WERE FORECASTED TO BE...BUT WINDS ARE STILL EXPECTED
TO FALL SOLIDLY WITHIN SCA CRITERIA. THEREAFTER... WINDS WILL
GRADUALLY DECREASE THROUGH FRIDAY NIGHT...WITH A FEW EXPECTED WIND
SURGES EXPECTED TO IMPACT THE WATERS THROUGH THE WEEKEND.

&&

.AVIATION...
UNTIL 12Z/16TH...CEILINGS OF BETWEEN OF AROUND 120 ACCOMPANIED BY
PERHAPS LIGHT RAIN OR SPRINKLES WILL PREDOMINATE AT THE KEY WEST AND
MARATHON TERMINALS FOR THE BALANCE OF THIS AFTERNOON AND EARLY
EVENING. HOWEVER...CEILINGS BETWEEN 030-035 ARE POSSIBLE AFTER 09Z.
MOSTLY NORTHWEST WINDS WILL FLUCTUATE BETWEEN 8 AND 11 KNOTS WITH
OCCASIONAL GUSTS OF BETWEEN 14 AND 17 KNOTS...BEFORE A STEADIER AND
MORE PRONOUNCED WIND INCREASE OCCURS AFTER 05Z.

&&

.KEY WATCHES/WARNINGS/ADVISORIES...
FL...NONE.
GM...SMALL CRAFT ADVISORY UNTIL 11 AM EST THURSDAY FOR GMZ031>035-
     042>044-052>055-072>075.
