AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KEY WEST FL
307 PM EST WED MAR 4 2015

.DISCUSSION...
CURRENTLY - A LARGE ATLANTIC HIGH EXTENDING A RIDGE ACROSS
FLORIDA...AND INTO THE GULF OF MEXICO...IS RETREATING EASTWARD. WINDS
HAVE TRENDED SLOWLY DOWNWARDS OVER THE PAST 24 HOURS...AND ARE GENTLE
TO MODERATE OUT OF THE EAST SOUTHEAST. TEMPERATURES WERE ABLE TO
CLIMB INTO THE LOWER 80S WITH DEW POINTS NEAR 70 DEGREES. DEEP
LAYERED RIDGING IS IN PLACE ACROSS THE FORECAST AREA...KEEPING MOSTLY
SUNNY TO PARTLY CLOUDY SKIES...WITH NO SHOWER DEVELOPMENT.

FORECAST - THE ATLANTIC RIDGE WILL CONTINUE TO RETREAT EASTWARD AS A
MIDLATITUDE SYSTEM MOVES INTO THE NORTHEASTERN UNITED STATES. SURFACE
WINDS WILL WEAKEN OUT OF THE EAST TO SOUTHEAST THROUGH MUCH OF THE
REMAINDER OF THE WEEK. DEEP LAYERED RIDGING WILL CONTINUE ACROSS THE
AREA. RAIN CHANCES WILL REMAIN SLIM TO NONE WITH MOSTLY SUNNY SKIES.
TEMPERATURES WILL REMAIN NEAR OR SLIGHTLY ABOVE NORMAL.

THE LONG WAVE TROUGH WILL SHIFT INTO THE EASTERN UNITED STATES LATE
THIS WEEK...AND AN ASSOCIATED FRONTAL BOUNDARY WILL SHIFT INTO
CENTRAL FLORIDA. DEEP LAYERED RIDGING WILL WEAKEN AT THIS TIME. THESE
FACTORS WILL RESULT IN SLIGHTLY COOLER TEMPS ALOFT...AND AN INCREASE
IN LOW LEVEL MOISTURE. WILL MAINTAIN INTRODUCING DIME POPS FRIDAY
NIGHT. MEANWHILE...A HIGH PRESSURE SPREADING SOUTHEASTWARD INTO THE
EASTERN UNITED STATES WILL CAUSE WINDS TO BACK TO NORTHEAST ON
FRIDAY. THE MORE NORTHERLY TRAJECTORY WILL ALLOW TEMPERATURES TO
SETTLE DOWN A FEW DEGREES TO NEAR OR SLIGHTLY BELOW NORMAL.

THIS NEW HIGH WILL WEAKEN AS IT SPREADS EASTWARD INTO THE ATLANTIC.
CONSEQUENTLY...WINDS ARE EXPECTED TO QUICKLY RETURN EASTERLY
RESULTING IN NEAR OR SLIGHTLY ABOVE NORMAL TEMPS. FOR NOW WILL HOLD
ONTO SLIGHT CHANCE OF POPS AS DEEP LAYERED RIDGING WILL REMAIN
DISPLACED EASTWARD OF OUR AREA...AND AT TIMES THERE WILL BE SOME ROOM
FOR WEAK SHOWER FORMATION TO DEVELOP IN THE RELATIVELY WARM MOIST
BOUNDARY LAYER.

&&

.MARINE...
SURFACE WINDS WILL WEAKEN FURTHER OVER THE NEXT COUPLE OF DAYS AS AN
ATLANTIC RIDGE WILL CONTINUE TO SHIFT EASTWARD. GENTLE WINDS WILL
BACK NORTHEAST ON FRIDAY AS ANOTHER HIGH SPREADS EAST AND
SOUTHEASTWARD OVER THE EASTERN UNITED STATES. THIS NEW HIGH WILL
WEAKEN AND SPREAD EASTWARD OVER THE WEEKEND. AS A RESULT...WINDS WILL
RETURN TO EASTERLY...AND REMAIN GENERALLY GENTLE TO MODERATE.

&&

.AVIATION...
VFR CONDITIONS EXPECTED TO PREVAIL AT THE KEY WEST AND
MARATHON AIRPORTS. CLOUDS WITH BASES AROUND 020 ARE POSSIBLE FROM
TIME TO TIME. WINDS GENERALLY SOUTHEAST WILL BE 6 TO 12 KNOTS WITH
OCCASIONAL GUSTS NEAR 18 KNOTS.
