AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KEY WEST FL
1031 PM EDT SUN MAR 29 2015

.DISCUSSION...
CURRENTLY - A HIGH PRESSURE SYSTEM CENTERED OVER THE CAROLINAS IS
SPREADING SOUTHEAST AND SOUTHWARD...AND FOR THE TIME BEING...KEEPING
A FAIRLY TIGHT PRESSURE GRADIENT ACROSS THE KEYS. NORTHEAST TO EAST
WINDS HAVE COME UP TO 15 TO 20 KNOTS ACROSS MOST KEYS WATERS...AND
GENERALLY 10 TO 15 MPH OVER LAND. STABLE CONDITIONS ARE IN PLACE
WITH DRY AIR PRESENT THROUGH MUCH OF THE COLUMN. TEMPERATURES ARE
CURRENTLY NEAR 70...WITH DEW POINTS NEAR 60.

SHORT TERM UPDATE (OVERNIGHT) - NEAR BREEZY NORTH TO EAST WINDS WILL
RELAX LATE TONIGHT AS THE HIGH CELL TO OUR NORTH SPREADS FURTHER
SOUTH AND SOUTHEAST...AND WEAKENS THE LOCAL PRESSURE GRADIENT. MOSTLY
CLEAR SKIES WITH WINDS RIGHT DOWN THE ISLAND CHAIN SHOULD LET
TEMPERATURES SETTLE A BIT FURTHER INTO THE MID TO UPPER 60S. STABLE
CONDITIONS WILL PREVAIL...AND NO PRECIPITATION WILL OCCUR. NO UPDATE
PLANNED FOR THE ZONE FORECAST.

&&

.MARINE...
WINDS HAVE INCREASED AGAIN THIS EVENING ACROSS KEYS WATERS...HENCE A
CAUTION IS IN PLACE FOR ALL MARINE ZONES. WINDS ARE EXPECTED TO TREND
DOWNWARDS TOWARDS THE END OF THE OVERNIGHT PERIOD AS A HIGH CELL
CENTERED OVER THE CAROLINAS SPREADS SOUTH AND
SOUTHEASTWARD...REDUCING THE LOCAL PRESSURE GRADIENT. WILL ONLY
ADJUST TRANSITIONAL WIND WORDING IN THE EVENING MARINE UPDATE.

&&

MARATHON AIRPORTS. SURFACE NORTHEAST TO EAST WINDS OF 6 TO 12 KNOTS
