AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
256 AM EST SUN DEC 18 2011

...DRIER AND COOLER WEATHER TODAY THROUGH EARLY THIS WEEK BEFORE
WARMING UP FOR THE SECOND HALF OF THE WEEK INTO THE CHRISTMAS WEEKEND...

.DISCUSSION...
A COLD FRONT OVER CENTRAL FLORIDA EARLY THIS MORNING WILL MOVE
THROUGH SOUTH FLORIDA THIS MORNING...AND BE LOCATED OVER THE
FLORIDA KEYS BY THIS AFTERNOON. THIS FRONT WILL BRING IN DRIER AND
COOLER WEATHER TO THE AREA FROM THE NORTH FOR TODAY INTO MONDAY.
THE HIGHS WILL BE IN THE 70S WITH LOWS IN THE 50S EXCEPT 60S FOR
THE EAST COAST METRO AREAS AND MID TO UPPER 40S WEST OF LAKE
OKEECHOBEE.

THE DRY WEATHER WILL REMAIN OVER THE CWA FOR TUESDAY INTO
WEDNESDAY...AS HIGH PRESSURE SETS UP OVER THE SOUTHEAST UNITED
STATES. THIS WILL ALSO ALLOW FOR THE WINDS TO SHIFT FROM A
NORTHERLY DIRECTION TODAY TO A EAST SOUTHEAST DIRECTION BY TUESDAY
INTO WEDNESDAY...AND ALLOW FOR A WARMING TREND TO START OVER THE
AREA. HIGHS ON TUESDAY AND WEDNESDAY WILL BE IN THE 80S WITH LOWS
AROUND 60...EXCEPT AROUND 70 EAST COAST METRO AREAS AND MID 50S
WEST OF LAKE OKEECHOBEE.

...EXTENDED FORECAST...
THE HIGH OVER THE SOUTHEAST UNITED STATES WILL MOVE EAST INTO THE
ATLANTIC WATERS BY END OF THIS WEEK INTO THE CHRISTMAS WEEKEND.
THIS WILL ALLOW FOR ANOTHER COLD FRONT TO WORK INTO FLORIDA FROM
THE NORTHWEST LATE THIS WEEK AND STALL OVER THE LAKE OKEECHOBEE
AREA CHRISTMAS WEEKEND...AND ALLOW FOR SOME LOW LEVEL MOISTURE TO
RETURN TO THE CWA FROM THE SOUTH. SO WILL KEEP THE SLIGHT CHANCE
OF SHOWERS IN THE FORECAST FOR LATE THIS WEEK INTO THE CHRISTMAS
WEEKEND OVER THE CWA. TEMPERATURES WILL ALSO CONTINUE TO RUN ABOVE
NORMAL WITH HIGHS IN THE 80S AND LOWS IN THE 60S EXCEPT AROUND 70
DEGREES EAST COAST METRO AREAS. THE AVERAGE HIGHS FOR THIS TIME
OF YEAR IS IN THE MID TO UPPER 70S WITH THE AVERAGE LOWS IN THE
MID TO UPPER 50S...EXCEPT LOWER 60S EAST COAST.

&&

.MARINE...
THE WINDS OVER THE CWA WATERS WILL BE NORTHERLY TODAY INTO TONIGHT
WITH WIND SPEEDS INCREASING TO 20 KNOTS BY TONIGHT. THE WINDS WILL
THEN SWING TO A EASTERLY DIRECTION MONDAY WITH SPEEDS REMAINING
AROUND 20 KNOTS....BEFORE SWINGING TO A SOUTHEAST DIRECTION FOR
THE MIDDLE OF THE WEEK WITH SPEEDS DECREASING TO LESS THAN 15
KNOTS.

THE SEAS WILL BE BUILDING TO 5 TO 7 FEET BY THIS AFTERNOON AND
REMAIN THERE THROUGH MONDAY. FOR THE REST OF THE ATLANTIC
WATERS...THE SEAS WILL BE BUILDING TO 4 TO 6 FEET BY THIS
AFTERNOON CONTINUING TO INCREASE TO 5 TO 7 FEET TONIGHT INTO
MONDAY. FOR THE GULF SIDE...THE SEAS WILL REMAIN BELOW 6 FEET
TODAY INTO MONDAY. SO WILL BE PUTTING UP A SCA FOR THE ATLANTIC
WATERS OF PALM BEACH COUNTY TODAY WITH A SCEC FOR REST OF SOUTH
FLORIDA WATERS DUE TO THE WINDS SPEEDS.

THE EASTERLY WINDS WILL ALSO LEAD TO AN INCREASE IN THE RISK OF
RIP CURRENTS FOR THE EAST COAST BEACHES OF SOUTH FLORIDA BY
TONIGHT AND CONTINUING THROUGH WEDNESDAY OF THIS WEEK. SO WILL
MENTION THIS IN THE MORNING HWO PACKAGE.

&&

.FIRE WEATHER...
THE COLD FRONT WILL BRING IN MUCH DRIER AIR TO THE AREA TODAY
ALLOWING FOR THE RELATIVE HUMIDITIES TO FALL INTO THE UPPER 30S
TO LOWER 40S OVER THE CWA...EXCEPT IN THE UPPER 40S TO LOWER 50S
EAST COAST AREAS AND INTO THE LOWER 30S OVER THE NORTHWEST
INTERIOR AREAS. THE ENERGY RELEASE COMPONENT OVER SOUTH FLORIDA
HAS BEEN RUNNING IN THE LOWER TO MID 20S FOR THE LAST COUPLE OF
DAYS...AND SHOULD CONTINUE AROUND THESE NUMBERS FOR TODAY. SO NO RED
FLAG WARNING IS NEEDED FOR THE NORTHWEST INTERIOR AREAS. WILL
CONTINUE TO MONITOR THE LATEST FORECAST MODELS AND CONDITIONS ON
THE RELATIVE HUMIDITIES THROUGH TODAY FOR THE POSSIBILITY OF A
FIRE DANGER STATEMENT...BUT AT THIS TIME THIS DOES NOT LOOK
LIKELY AS WELL.
