AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE MIAMI FL
125 PM EDT WED APR 22 2009

.AVIATION...VFR UNDER CLEAR SKIES WILL PREVAIL. NW WINDS ALONG THE
EAST COAST WILL BECOME NE OVER THE NEXT FEW HRS. TFLL RADAR ALREADY
SHOWING THE SEA BREEZE BEGINNING TO DEVELOP...SO WIND FCST LOOKS ON
TRACK...JUST DELAYED THE SWITCH TO NE BY AN HR/19Z. KAPF ALREADY HAS
THE SEA BREEZE. WINDS OVERNIGHT WILL BECOME LIGHT/VAR WITH THE
POSSIBILITY OF A LAND BREEZE DEVELOPING AS DEPICTED BY THE WRF. /DG

&&

.UPDATE....SURFACE ANALYSIS SHOWS HIGH ACROSS THE CWA WITH COOL
START THIS MORNING. 12Z SOUNDING CAME DRIER THAN ALL GUIDANCE WITH
PWAT OF 0.32 INCHES. SKIES SHOULD REMAIN MOSTLY CLOUD FREE TODAY
AND TONIGHT AND UPDATED GRIDS TO REFLECT THAT. THE EXCEPTION TO
THIS IS DEW POINT BOUNDARY CURRENTLY ACROSS CENTRAL FLORIDA MOVING
SOUTH AROUND 16 KNOTS WITH DEW POINTS FALLING BY 10 DEGREES OR SO
BEHIND IT AND A FEW CLOUDS ALONG ITS LEADING EDGE. NEEDLESS TO
SAY NO PRECIP WHAT SO EVER. THE MAIN CONCERN TODAY IS FIRE
WEATHER. MODEL GUIDANCE...AND IN PARTICULAR LOCAL WRF PLUMMET THE
MINRHS THIS AFTERNOON ACROSS MUCH OF THE AREA EVEN WHEN ITS
INITIAL MOISTURE PROFILES WERE MOISTER THAN THE OBSERVED IN THE
SNDG. THAT IS THE SAME STORY WITH THE OTHER MODELS. ALSO...THE
COOL START THIS MORNING HAS RESULTED IN A REINFORCED LAND BREEZE
WITH SNDG SHOWING NNW WINDS ABOVE THE SURFACE TOO. THE BOTTOM LINE
IS I BELIEVE THE ONSET OF ONSHORE WINDS ON THE EAST COAST WILL
LIKELY NOT TAKE PLACE UNTIL LATER THIS AFTERNOON. GIVEN THAT...THE
MIXING ASSOCIATED WITH THE DRY ATMOSPHERIC PROFILES...AND ANY
REINFORCEMENT OF DRY AIR FROM DEW POINT FRONT IF IT MAKES IT INTO
THE AREA THIS AFTERNOON...IS THAT RED FLAG WARNINGS CURRENTLY IN
PLACE ARE A SAFE BED. IN FACT...DECIDED TO EXTEND THEM INTO THE
METRO ZONES OF PALM BEACH TO MIAMI DADE AND FAR SOUTH MIAMI DADE
EXCLUDING COASTAL SECTIONS WHERE THE ONSET OF THE ONSHORE WINDS
THIS AFTERNOON WILL LIKELY PREVENT MINRH TO DROP BELOW 35 PERCENT
FOR 4 HOURS OR LONGER.

.MARINE...ADJUSTED WAVE HEIGHTS DOWN A BIT GIVEN OBSERVATIONS.
THERE IS STILL A GOOD CHANCE SEAS IN THE GULF STREAM COULD BUILD
UP TO 7 FEET LATER THIS AFTERNOON FOR A BRIEF PERIOD OF TIME
BEFORE WINDS SWITCH FROM THE EAST. THE ADVISORY ONLY APPLIES TO
THE GULF STREAM WATERS AND IT WILL BE IN EFFECT UNTIL 8 PM THIS
EVENING.

&&

PREV DISCUSSION... /ISSUED 730 AM EDT WED APR 22 2009/

AVIATION...VFR UNDER A MOSTLY CLEAR SKY WILL PREVAIL THROUGH THE
PERIOD. FOR KAPF...WINDS WILL PREVAIL OUT OF THE NE THEN SWITCH TO
THE WEST AT NEAR 12 KT THIS AFTERNOON AS A SEA BREEZE DEVELOPS.
FOR ALL THE EAST COAST TERMINALS...WINDS WILL PREVAIL OUT OF THE
NW AT 5-10 KT UNTIL WINDS TURN NE AT NEAR 12 KT THIS AFTERNOON
(MOST LIKELY BETWEEN 1-2 PM). LIGHT/VAR WINDS ARE THEN EXPECTED
AGAIN BY LATE TONIGHT. /DG

PREV DISCUSSION... /ISSUED 428 AM EDT WED APR 22 2009/

CLIMATE...
TEMPS EARLY THIS MORNING HAVE BEEN RUNNING IN THE UPPER 40S TO
LOWER 50S OVER THE INTERIOR AREAS OF SOUTH FLORIDA. THESE EARLY
MORNING TEMPS SHOULD REMAIN NEARLY STATIONARY THROUGH THE NEXT
COUPLE OF HOURS WHICH ARE ABOUT 10 DEGREES COOLER THAN NORMAL FOR
THIS TIME OF YEAR.

ALSO A FEW LOCATION OVER THE INTERIOR AREAS ARE ALSO NEAR RECORD
LOWS FOR THIS TIME OF YEAR WHICH ARE:

CITIES      CURRENT TEMPS 4 AM EDT     RECORD LOWS
IMMOKALEE            51                 51 - 1988

PREV DISCUSSION... /ISSUED 328 AM EDT WED APR 22 2009/

HIGH PRES WILL MOVE FROM THE GULF OVER THE FLA PENINSULA TODAY
AND INTO THE ATLC THU AND REMAIN CENTERED OVER THE ATLC OFF OF
THE SE U.S. COAST.

FOR THE SHORT TERM...TODAY THROUGH FRI...WESTERLY FLOW WILL PREVAIL
OVER S FLA TODAY EXCEPT ALONG THE IMMEDIATE E COAST WHERE AN E COAST
SEA BREEZE WILL DEVELOP. STILL MAX TEMPS WILL BE AROUND 80 ON THE W
COAST BUT REACHING POSSIBLY THE MID 80S IN MANY AREAS ON THE E COAST
BEFORE THE SEA BREEZE SETS IN. WIND WILL BE OFF OF THE ATLC THU AND
FRI WITH THE MAX TEMP PATTERN REVERSED. THE SLIGHTLY COOL TEMPS OVER
THE AREA THIS MORNING WILL GRADUALLY BE MODIFIED UP TONIGHT AND THU
NIGHT. LOOKS LIKE IT WILL BE DRY THROUGH THIS PERIOD.

EXTENDED PERIOD...SAT THROUGH TUE...DRY SAT BUT A PERSISTENT
EASTERLY FLOW GRADUALLY INCREASE MOISTURE AND MINIMAL NOCTURNAL
SHOWERS WILL IMPACT TO E COAST AND DIURNAL SHOWERS IN THE INTERIOR
AND W.

MARINE...AS HIGH PRES BUILDS IN...WINDS BECOME MORE NW THEN N
THROUGH THE DAY AND GRADUALLY DECREASE. BUT THE NORTHERLY FLOW WILL
NUDGE GULF STREAM SEAS TO 7 FEET TODAY THROUGH EARLY EVENING.
ADVISORY ALREADY OUT AND WILL KEEP THE HIGHLIGHT. WINDS CONTINUE TO
VEER BUT GULF STREAM SEAS 5 FEET AT LEAST THROUGH THU. EASTERLY FLOW
INCREASES FRI INTO THE WEEKEND AND CAUTION AT LEAST MAY BE REQUIRED.
RIP CURRENTS WILL HAVE AN INCREASED THREAT TO THE ATLC BEACHES THU
THROUGH THE WEEKEND AT LEAST.

FIRE WEATHER...ALREADY SEEING SOME POCKETS OF DEW POINTS BELOW
/AROUND 50. UPSTREAM 00Z ROABS AND FORECAST MODEL SOUNDING INDICATE
THAT DEW POINTS BELOW 50 COULD BECOME WIDESPREAD ACROSS S FLA AND
TEMPS REACH LOWER TO MID 80S AND DRY AIR ALOFT MIXES DOWNWARD. THE
IMMEDIATE W COAST AREAS WILL BE SPARED AS WINDS THROUGH THE DAY WILL
BE WESTERLY. ON THE EAST COAST...A SEA BREEZE IS EXPECTED TO DEVELOP
IN THE AFTERNOON HOURS SPARING THE E COAST ZONES AND METRO AREAS
OF MIAMI-DADE AND PALM BEACH THOUGH 2 HOURS BELOW 35 PERCENT MAY
OCCUR. SOME DRY AIR WILL PERSIST OVER THE INTERIOR ZONES AND A FIRE
WEATHER WATCH WILL BE IN EFFECT FOR GLADES...HENDRY AND INLAND
