AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
956 AM EST SUN FEB 18 2007

.UPDATE...COLD FRONT CONTINUING TO MAKE QUICK PROGRESS TO THE SE
WITH ITS CURRENT POSITION FROM ABOUT PBI TO EVERGLADES CITY AND
MOVING AT ABOUT 35 MPH. THIS SHOULD PUT IT OFF THE SE CST BY 16Z
OR EVEN EARLIER AND STRONG CAA BEHIND IT. MY CONCERN WITH THIS IS
THE TEMPS FOR THIS AFTERNOON. EVEN THOUGH SKIES WILL BE CLEARING
WE MIGHT STRUGGLE TO GET OUT OF THE LOWER 60S. GUIDANCE DOES SHOW
TEMPS GETTING INTO THE UPPER 60S BUT THIS MAY BE DOUBTFUL. WILL
LOWER THE AFTERNOON TEMPS TO ACCOUNT FOR THIS THINKING. THE
1000-850 THICKNESSES ALSO ARE NOT FORECAST TO GET DOWN AS LOW AS
WITH SATURDAY MORNINGS EVENT BUT STILL LOW ENOUGH FOR A POSSIBLE
FREEZE AROUND LAKE OKEE. THE OTHER CONCERN IS THAT THE SFC HIGH
WILL BE RAPIDLY MOVING TO THE EAST TONIGHT ALONG THE GULF CST AND
THIS MAY HELP KEEP WINDS UP BUT STILL THINK WITH CLEARING SKIES
WINDS OVER THE INTERIOR ZONES WILL BECOME LIGHT ENOUGH TO ALLOW
WIND SHELTERED AREAS TO GO CALM AND TEMPS COULD FALL TO FREEZING
OR SLIGHTLY BELOW. SO WILL NO DOUBT ISSUE FREEZE WARNING FOR
GLADES, HENDRY, NORTHERN COLLIER AND WESTERN PALM BEACH COUNTIES
AND WILL GET THIS PRODUCT OUT NO LATER THAN NOON. WITH THE WIND
CONSIDERATION, MAY ALSO HAVE TO ISSUE WIND CHILL ADVISORY FOR MUCH
OF THE REMAINDER OF S FLA BUT WILL DECIDE ON THAT WITH THE EARLY
AFTERNOON DISCUSSION AND ZONE ISSUANCE.

.PREV DISCUSSION... /ISSUED 425 AM EST SUN FEB 18 2007/

..STRONG COLD FRONT TO MOVE THROUGH SOUTH FLORIDA TODAY...
..INCREASED FIRE DANGER MOST AREAS THIS AFTERNOON...
..FREEZING TEMPERATURES PROBABLE ACROSS INTERIOR SOUTH FLORIDA
LATE TONIGHT TO EARLY MONDAY MORNING...

SYNOPSIS...COLD FRONT EXTENDING ACROSS NORTH-CENTRAL FLORIDA AT
08Z WITH A LINE OF MODERATE TO HEAVY SHOWERS AHEAD OF IT EXTENDING
FROM DAYTONA BEACH TO SARASOTA. SFC WINDS RAPIDLY AND
SIGNIFICANTLY INCREASING FROM THE NORTHWEST BEHIND THE FRONT WITH
MOST BUOYS IN NE GULF OF MEX REPORTING SUSTAINED 30 KTS AND GUSTS
TO NEAR 40 KNOTS. CLOUDLESS NIGHT OVER SOUTH FLORIDA WITH WINDS ON
THE CALM/LIGHT SIDE AND TEMPS RANGING FROM AROUND 40 DEGREES
GLADES COUNTY TO THE UPPER 40S EASTERN METRO AREAS AND AROUND 60 NAPLES.

SHORT TERM...TODAY AND TONIGHT...COLD FRONT SHOULD CONTINUE TO
MOVE RAPIDLY SOUTH WITH CLODS AND SHOWERS AHEAD OF THE FRONT
BEGINNING TO AFFECT NRN PORTIONS OF SOUTH FLORIDA BEFORE SUNRISE.
THE SHOWERS ARE THEN EXPECTED TO BE IN THE MIAMI AREA DURING THE
MORNING HOURS. THE FRNT ITSELF WILL MOVE THROUGH MIAMI DURING THE
LATE MORNING HOURS OR AROUND NOON WITH A RAPID DECREASE IN CLOUDS
AND SHOWERS. BREEZY TO WINDY CONDITIONS SHOULD SPREAD SOUTH BEHIND
THE BOUNDARY. WIND GUSTS UP TO 30 TO 35 MPH CAN BE EXPECTED AS THE
FRONT MOVES THROUGH SOUTH FLORIDA.

LATEST GFS AND NAM RUN SUGGEST LOW TEMPS TONIGHT/MONDAY MORNING COULD
RIVAL THE ONE EXPERIENCED SATURDAY MORNING WITH TEMPS HOVERING
AROUND THE FREEZING MARK IN GLADES/HENDRY AND WESTERN PALM BEACH
COUNTIES AND IN THE LOWER 40S COASTAL AREAS. HENCE THE FREEZE WATCH
FOR NORTHERN INTERIOR SECTIONS OF SOUTH FLORIDA. THE ONLY FLY IN
THE OINTMENT IS THE EXPECTED WIND SPEED FOR TONIGHT. WINDS SPEED OF
5 TO 10 MPH WITH HIGHER GUSTS ARE EXPECTED OVER THE AREAS UNDER
THE WATCH. THIS COULD PROMOTE MIXING AND PREVENT TEMPS FROM
REACHING THE FREEZING MARK. WILL BRIEF DAY FORECASTER ON THIS AND
LET THEM ANALISE FURTHER DATA BEFORE MAKING A DECISION.

THE EXPECTED WIND SPEED FOR TONIGHT COULD ALSO RESULT IN WIND
CHILL VALUES BELOW ADVISORY CRITERIA OVER COASTAL AREAS IN PALM
BEACH COUNTY. IN VIEW OF THIS DECIDED TO GO AHEAD AND ISSUE A WIND
CHILL ADVISORY FOR PALM BEACH COUNTY STARTING AFTER MIDNIGHT
TONIGHT. ALTHOUGH WIND CHILL VALUES MAY FALL BELOW 35 DEGREES
ACROSS BROWARD/MIAMI-DADE COUNTY AS WELL...IS EXPECTED TO BE FOR A
SHORT DURATION DURING THE EARLY MORNING HOURS.

LONG TERM...MONDAY THROUGH SATURDAY...THE COLD FRONT WILL
CONTINUE TO MOVE SOUTHEAST AND SFC HIGH BEHIND WILL MOVE FROM THE
GULF OF MEX EAST TO WESTERN ATLANTIC JUST NE OF THE BAHAMAS BY TUE
MORNING. THIS SYSTEM WILL THEN BECOME THE DOMINANT WX FEATURE
THROUGH THIS ENTIRE FORECAST PERIOD. EAST TO SOUTHEAST SFC WIND
FLOW AROUND THIS HIGH WILL OCCASIONALLY ADVECT PATCHES OF
CLOUDS/MOISTURE BACK OVER SOUTH FLORIDA BUT FOR THE MOST PART
FAIRLY DRY CONDITIONS SHOULD PREVAIL. TEMPS WILL BOUNCE BACK
QUICKLY BY MID WEEK WITH AFTERNOON TEMPS REACHING THE MID 80S BY
THE END OF THE WEEK.

AVIATION...CLOUDS WILL CONTINUE TO INCREASE THIS MORNING AS A COLD FRONT
APPROACHES FROM THE NORTH. A FEW SHOWERS WILL ALSO BE AROUND SOUTH
FLORIDA THIS MORNING AS THE FRONT MOVES THROUGH, AND VCSH HAS BEEN
LEFT IN ALL TAFS DURING A PORTION OF THE MORNING. BEHIND THE FRONT
WINDS WILL INCREASE AND BECOME GUSTY TO OVER 20 ACROSS SOUTH FLORIDA
DURING THE AFTERNOON.

MARINE...AS INDICATED ABOVE BUOYS IN THE E-CENTRAL GULF ALREADY
INDICATING SUSTAINED WINDS AROUND 30 KTS WITH GUSTS TO AROUND 40
KTS BEHIND THE FRONT. EXPECTED THESE WINDS TO RAPIDLY REACH OUR
GULF WATERS AND LAKE OKEECHOBEE BEFORE SUNRISE AND THEN SPREAD
OVER BISCAYNE BAY AND ATLANTIC WATERS DURING THE MORNING HOURS.
WIND GUSTS WILL LIKELY REACH GALE FORCE AND SO THE FORECAST WILL
INDICATE THAT. ALTHOUGH WINDS ARE EXPECTED TO DECREASE
SIGNIFICANTLY FOR TONIGHT...AN IMPROVEMENT IN THE SEAS WILL LAG
BEHIND AND SO THE SMALL CRAFT ADVISORY CONDITIONS ARE LIKELY TO
REMAIN IN PLACE AT LEAST FOR ATLC/GULF OF MEX WATERS THROUGH
MONDAY MORNING.

FIRE WEATHER...A RATHER DRY AIR MASS WITH DEWPOINTS FROM THE
UPPER 20S TO AROUND 40 IS EXPECTED TO SPREAD SOUTH BEHIND THE
FRONT THIS AFTERNOON. THIS WILL RESULT IN RH BELOW 35% FOR QUITE A
FEW HOURS THIS AFTERNOON. WINDS SPEED HIGHER THAN 15 MPH WILL
AGGRAVATE THE FIRE DANGER TODAY. THEREFORE...DECIDED TO GO AHEAD
WITH RED FLAG WARNING FOR THE AREAS PREVIOUSLY UNDER A FIRE
WEATHER WATCH.
