AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
303 PM EST WED FEB 27 2008

.DISCUSSION...

.TONIGHT...
THE MID TO UPPER LEVEL CLOUDS WERE STILL OVER SOUTH FLORIDA EARLY
THIS AFTERNOON...DUE TO THE MID TO UPPER LEVEL FLOW STILL FROM THE
SOUTHWEST AHEAD OF THE MID TO UPPER LEVEL TROUGH OF LOW PRESSURE
OVER THE GULF OF MEXICO. A FEW SPRINKLES WERE ALSO SHOWING UP ON
THE MIA DOPPLER RADAR OVER SOUTH FLORIDA EARLY THIS AFTERNOON.

THE MID TO UPPER LEVEL TROUGH OF LOW PRESSURE WILL CONTINUE TO
MOVE EAST THIS AFTERNOON AND THROUGH SOUTH FLORIDA THIS EVENING.
THIS WILL ALLOW FOR THE CLOUDS OVER SOUTH FLORIDA TO BE PUSH EAST
INTO THE ATLANTIC WATERS THIS EVENING LEAVING CLEAR SKIES TONIGHT
OVER THE AREA. AT THE SAME TIME...HIGH PRESSURE OVER TEXAS WILL
MOVE EAST INTO THE SOUTHERN GULF COAST STATES TONIGHT. THIS WILL
KEEP THE NORTHWEST WIND FLOW OVER THE CWA TONIGHT...AND ALLOW FOR THE
WINDS TO DECREASE FROM THE BREEZY TO WINDY CONDITIONS THIS
AFTERNOON TO AROUND 5 MPH OVER THE INTERIOR AREAS AND 5 TO 10 MPH
OVER THE METRO AREAS TONIGHT.

TEMPS WILL ALSO CONTINUE TO FALL THIS AFTERNOON INTO TONIGHT...AND
BY SUNRISE RISE WEDNESDAY LOW TEMPS SHOULD BE IN THE MID 30S OVER
THE INTERIOR AREAS TO AROUND 40 ALONG THE EAST COAST METRO AREAS.
THE ONLY EXCEPTION TO THIS IS OVER THE METRO AREAS OF BROWARD AND
MIAMI-DADE COUNTIES WHERE THE LOW TEMPS WILL FALL DOWN INTO THE
LOWER TO MID 40S. THE LOW TEMPS TONIGHT OVER GLADES AND HENDRY
COULD ALSO APPROACH NEAR RECORD LOWS WHICH ARE:

              FORECAST LOWS      RECORD LOWS
MOORE HAVEN        36             33 - 1935
IMMOKALEE          35             35 - 1980
DEVILS GARDEN      36             32 - 1968
CLEWISTON          39             36 - 2002

THE WIND CHILLS WILL ALSO BE ABLE TO FALL TO AROUND 30 OVER THE
NORTHERN INTERIOR AREAS TO LOWER 30S OVER THE SOUTHERN INTERIOR
AREAS...AND 30 TO 35 OVER THE METRO AREAS. THE ONLY EXCEPTION TO
THIS IS THAT COASTAL PALM BEACH...AND THE METRO AREAS OF MIAMI-
DADE AND BROWARD COUNTIES WILL ONLY GET DOWN INTO THE UPPER 30S TO
LOWER 40S. SO WILL CANCEL THE WIND CHILL WATCH FOR THE COASTAL
AREA OF PALM BEACH COUNTY...AND THE FOR THE SOUTHERN MIAMI-DADE
COASTAL AREAS FOR TONIGHT. THE WIND CHILL WATCH WILL BE UPGRADED
TO A WIND CHILL ADVISORY FOR REST OF THE AREAS THAT ARE IN THE
WIND CHILL WATCH FOR TONIGHT.

.THURSDAY THROUGH FRIDAY... HIGH PRESSURE WILL CONTINUE TO MOVE EAST INTO
THE NORTH FLORIDA ON THURSDAY AND THURSDAY NIGHT. THIS WILL KEEP
THE VERY DRY AIR OVER THE CWA DURING THIS TIME ALONG WITH LIGHT
WINDS OVER MOST OF THE CWA FOR THURSDAY NIGHT. HIGH TEMPS ON
THURSDAY WILL BE IN THE 60S OVER ALL OF THE CWA...AND THE LOWS
THURSDAY NIGHT WILL RANGE FROM THE MID 30S OVER THE NORTHWEST
INTERIOR AREAS TO THE UPPER 40S TO MID 50S OVER THE EAST COASTAL
AREAS. THE WEST COAST WILL ALSO SEE LOW TEMPS IN THE MID 40S. WITH
LIGHT WINDS OVER THE NORTHWEST INTERIOR AREAS AND LOW TEMPS IN THE
MID 30S WILL ALSO ADD PATCHY FROST FOR GLADES AND HENDRY COUNTIES
FOR THURSDAY NIGHT.

THE HIGH WILL SLOWLY MOVE EAST INTO THE ATLANTIC WATERS LATE THIS
WEEK ALLOWING FOR THE WINDS TO SWING TO A EASTERLY DIRECTION AND
ALLOW FOR SOME SLOW WARMING IN TEMPS. THE WEATHER WILL ALSO REMAIN
DRY.

.EXTENDED FORECAST...
A COLD FRONT OVER THE NORTHWEST UNITED STATES WILL ALSO MOVE
SOUTHEAST AND DOWN INTO SOUTH FLORIDA THIS WEEKEND. HOWEVER...THE
FRONT WILL BE VERY WEAK BY THE TIME IT GETS TO SOUTH FLORIDA. SO
WILL ONLY HAVE A FEW SHOWERS IN THE FORECAST FOR THIS WEEKEND AND
NEAR NORMAL TEMPERATURES.

THE LONG RANGE MODELS ARE STARTING TO SHOW THAT LOW PRESSURE WILL
DEVELOP OVER THE SOUTHERN CENTRAL GULF COASTAL STATES LATE THIS
WEEKEND...AND SLOWLY MOVE EAST INTO THE WESTERN ATLANTIC WATERS
EARLY NEXT WEEK. THIS LOW WILL PUSH A COLD FRONT THROUGH THE CWA
EARLY NEXT WEEK THAT COULD HAVE A LINE OF SHOWERS AND THUNDERSTORMS
ALONG IT. SO WILL CONTINUE TO MENTION SHOWERS AND THUNDERSTORMS FOR
EARLY NEXT WEEK.

GFS FOR SEVERAL RUNS NOW HAS BEEN SHOWING A VIGOROUS SHORTWAVE
TROUGH DIVING OUT FROM THE MIDWEST AND CLOSING OFF OVER THE GEORGIA
AS IT CONNECTS WITH SOUTHERN STREAM ENERGY. THE LATEST 12Z ECWMF IS
NOW COMING IN LINE WITH THE GFS SOLUTION OF CUTTING OFF THIS LOW AT
SUCH A LOW LATITUDE. THIS IS FAR OUT IN TIME SO SOLUTIONS COULD
EASILY CHANGE...BUT THIS BEARS WATCHING FOR POTENTIAL SEVERE WEATHER
EARLY NEXT WEEK. FOR NOW...WILL INCLUDE STRONG STORM MENTION IN THE
HAZARDOUS WEATHER OUTLOOK...AND WE CAN TREND WORDING UP OR DOWN
BASED ON HOW THIS EVOLVES THROUGH THE WEEKEND.

&&

.AVIATION...
SOUTH FLORIDA TAF SITES SHOULD REMAIN THE VFR CONDITIONS TONIGHT
INTO THURSDAY. THE WINDS WILL REMAIN OUT OF THE NORTHWEST BETWEEN
15 TO 20 KNOTS THROUGH THIS EVENING...BEFORE FALLING BELOW 15
KNOTS LATE TONIGHT INTO THURSDAY. THE WEATHER WILL ALSO BE DRY AT
ALL THE TAF SITES.

&&

.MARINE...
THE WINDS EARLY THIS AFTERNOON HAVE BEEN FROM THE NORTHWEST AT 20
TO 25 KNOTS MOST OF THE CWA WATERS...EXCEPT AROUND 20 KNOTS OVER
BISCAYNE BAY AND THE NEAR-SHORE GULF WATERS. THIS DIRECTION AND
SPEED WILL CONTINUE THIS EVENING BEFORE DECREASING TO 15 TO 20
KNOTS AFTER MIDNIGHT OVER ALL OF THE CWA WATERS. THE DIRECTION
WILL THEN SWING SLOWLY TO THE EAST THROUGH FRIDAY...WHILE THE
SPEEDS SLOWLY DECREASE TO 10 TO 15 KNOTS.

THE GULF STREAM SEAS WILL BE 9 TO 11 FEET TONIGHT THROUGH
THURSDAY...BEFORE SLOWLY DECREASING TO BELOW 6 FEET BY FRIDAY. THE
NEAR-SHORE SEAS WILL REMAIN BELOW 6 FEET THROUGH FRIDAY.

FOR THE GULF SIDE...THE NEAR-SHORE SEAS WILL ALSO REMAIN BELOW 6
FEET. HOWEVER...THE OFFSHORE GULF WATERS WILL SLOWLY FALL FROM 6
TO 8 FEET THIS AFTERNOON TO LESS THAN 6 FEET BY THURSDAY.

SO WILL CONTINUE WITH THE SCA FOR ALL THE CWA WATERS UNTIL
MIDNIGHT...THAN A SCA FOR THE GULF STREAM SEAS FROM MIDNIGHT
TONIGHT THROUGH THURSDAY AFTERNOON.

&&

.FIRE WEATHER...
THE VERY DRY AIR TO THE NORTH WILL CONTINUE TO WORK INTO SOUTH
FLORIDA TONIGHT. BY THURSDAY...THE DEW POINTS WILL RANGE FROM THE
20S OVER THE WESTERN AREAS TO THE 30S OVER THE EASTERN AREAS.
TEMPS WILL ALSO BE IN THE 60S. THIS WILL ALLOW FOR THE RELATIVE
HUMIDITIES TO BE BELOW 35 PERCENT MORE THAN 4 HOURS ON THURSDAY. SO
HAVE ISSUED A RED FLAG WARNING FOR ALL OF THE CWA FOR THURSDAY
AFTERNOON INTO THURSDAY EVENING.
