AREA FORECAST DISCUSSION FOR THE FLORIDA KEYS
NATIONAL WEATHER SERVICE KEY WEST FL
358 PM EDT SUN MAR 20 2011

.DISCUSSION...
CURRENTLY - A SPRAWLING HIGH PRESSURE SYSTEM IS BUILDING DOWN THE
ATLANTIC COAST TOWARDS FLORIDA. LOCAL WINDS HAVE INCREASED OUT OF THE
EAST...AND ARE EAST AROUND 15 AND GUSTY OVER THE ISLAND CHAIN...AND A
BIT HIGHER AT THE CMANS ALONG THE REEF. VISIBLE SATELLITE IMAGERY
DEPICTS A BROAD ARC OF CLOUDS ASSOCIATED WITH THE WIND SURGE. DEW
POINT TEMPERATURES HAVE INCREASED A COUPLE OF DEGREES...AND WHILE
WEAK...AN ISLAND CLOUD LINE DID DEVELOP TODAY. NO SHOWER ACTIVITY WAS
PRESENT ACROSS THE KEYS AREA...AS CONDITIONS WERE TO STABLE FOR
SHOWER DEVELOPMENT.

FORECAST - WINDS WILL INCREASE OVER THE NEXT 12 HOURS AS HIGH
PRESSURE BUILDS SOUTHWARD INTO NORTH FLORIDA. BREEZY NORTHEAST TO
EAST WINDS WILL PERSIST ACROSS THE KEYS AREA TONIGHT AND INTO MONDAY
NIGHT. A FEW SHOWERS WILL BE POSSIBLE AS THE ENHANCED LOW LEVEL
MOISTURE AND CONFLUENT FLOW...ALONG WITH COOLER MID LEVEL
TEMPERATURES MOVE THROUGH THE KEYS AREA AT AROUND THE SAME TIME. QPF
WILL BE QUITE LIMITED DUE TO THE ISOLATED FAST MOVING NATURE OF ANY
ACTIVITY.

THEREAFTER MEAN MID AND UPPER LEVEL RIDGING WILL MOVE INTO THE KEYS
AREA...WHILE A SUCCESSION OF MID LATITUDE TROUGHS PUSH THE SURFACE RIDGE
AXIS SOUTHWARD CLOSER AND CLOSER TO THE KEYS. EXPECT INCREASING
STABILITY THROUGH THE WEEK AS WINDS VEER TO EAST TO SOUTHEAST AND
RELAX BY THURSDAY. LOCAL EFFECTS OF HEATING OVER SOUTH FLORIDA AND
CUBA WILL INCREASINGLY DOMINATE THE WIND REGIME AS THE RIDGE DRAWS
NEAR. AT THIS POINT WILL KEEP POPS OUT OF THE FORECAST IN THE MEDIUM
AND EXTENDED AS MOISTURE WILL BE LIMITED AND IT IS STILL UNCERTAIN
IF ANY CONVECTION WILL BE ABLE TO DEVELOP THIS EARLY IN SPRING WITH
SUCH A STABLE SYNOPTIC SETUP.

&&

.MARINE...
WINDS WILL INCREASE FURTHER OVER THE NEXT 12 HOURS AS STRONG RIDGING
EXPANDS DOWN THE ATLANTIC COAST INTO NORTH FLORIDA. A SMALL CRAFT
ADVISORY WILL BE REQUIRED FOR THE ATLANTIC WATERS...AND MAY BE
REQUIRED FOR THE GULF AND BAY SIDE AS WELL SHOULD CONDITIONS WARRANT.
THE TIGHT GRADIENT WILL REMAIN INTO TOMORROW NIGHT. MARINERS CAN
EXPECT THE USUAL PEAKS AND LULLS TO OCCUR. AT THIS POINT THE MOST
LIKELY TIMES FOR SURGES WILL BE THIS EVENING AND TOMORROW EVENING.
THEREAFTER...THE RIDGE TO OUR NORTH WILL STEADILY SHIFT
SOUTHWARD...MOVING INTO SOUTH FLORIDA AND THE KEYS BY LATE WEDNESDAY
OR THURSDAY. AS A RESULT...WINDS WILL GRADUALLY DECREASE AND VEER
FROM MONDAY NIGHT.

&&

.AVIATION...
THROUGH 12Z...STRATOCUMULUS BETWEEN 3 AND 5000 FEET WILL BE ON THE
INCREASE WITH CEILINGS NEAR 3000 FEET LIKELY AFTER MIDNIGHT AND
PERSISTING INTO EARLY MORNING. OTHERWISE...NORTHEAST TO EAST WINDS
OF 10 TO 15 KNOTS WITH GUSTS NEAR 20 KNOTS CAN BE EXPECTED...WITH
OCCASIONAL LULLS AND MINOR SURGES.
