.PREV DISCUSSION... /ISSUED 234 PM EST TUE DEC 27 2011/

..COOLER AND DRY WEATHER ON THE WAY TO SOUTH FLORIDA FOR REST OF
THE WEEK...

DISCUSSION...
LOW PRESSURE WAS LOCATED OVER OHIO VALLEY EARLY THIS AFTERNOON
WITH A TRAILING COLD FRONT SOUTHWEST INTO NORTH FLORIDA AND THEN
CONTINUING SOUTHWEST TO JUST WEST OF NAPLES AREA. THE LOW WILL
CONTINUE TO MOVE NORTHEAST INTO THE EASTERN GREAT LAKES REGION
BY THIS EVENING...AS THE COLD FRONT CONTINUES TO MOVE SOUTHEAST
AND THROUGH SOUTH FLORIDA. A LINE OF BROKEN SHOWER AHEAD OF THE
FRONT WILL ALSO CONTINUE TO MOVE SOUTHEAST AND THROUGH SOUTH
FLORIDA LATE THIS AFTERNOON INTO EARLY THIS EVENING. ONCE THE FRONT
CLEARS SOUTH FLORIDA AROUND MIDNIGHT...THE DRIER AND COOLER WEATHER
WILL WORK INTO THE AREA FROM THE NORTH FOR WEDNESDAY INTO THURSDAY
AS HIGH PRESSURE BUILDS INTO THE AREA FROM THE CENTRAL UNITED
STATES.

HIGHS FOR WEDNESDAY AND THURSDAY WILL BE IN THE 70S EXCEPT FOR
THE LAKE OKEECHOBEE AREA WHERE THEY WILL BE IN THE UPPER 60S ON
WEDNESDAY. LOWS TONIGHT WILL BE IN THE UPPER 40S TO LOWER 50S
AROUND LAKE OKEECHOBEE TO THE MID 50S TO LOWER 60S ALONG THE METRO
AREAS OF THE EAST AND WEST COAST. THURSDAY NIGHT WILL BE THE
COOLEST NIGHT ACROSS THE AREA WITH LOWS AROUND 40 NEAR LAKE
OKEECHOBEE TO THE UPPER 40S TO MID 50S ALONG THE EAST COAST METRO
AREAS. THE ONLY EXCEPTION IS THAT WEST OF LAKE OKEECHOBEE WHERE
THE LOWS SHOULD FALL INTO THE MID TO UPPER 30S. AT THIS TIME...DO
NOT EXPECT AREAS OF FROST WEST OF LAKE OKEECHOBEE DUE TO THE VERY
DRY AIR, BUT THERE COULD STILL BE A FEW ISOLATED AREAS THAT COULD
SEE PATCHY FROST ESPECIALLY IN WIND PROTECTED AREAS.

EXTENDED FORECAST...
THE HIGH OVER THE FLORIDA PENINSULA WILL SLOWLY MOVE EAST INTO THE
WESTERN ATLANTIC WATERS THIS NEW YEAR'S WEEKEND. THIS WILL ALLOW
FOR THE WINDS TO SWING FROM A NORTHERLY DIRECTION LATE THIS WEEK
TO A EASTERLY DIRECTION BY NEW YEAR'S DAY...AND ALLOW FOR THE
TEMPERATURES TO SLOWLY WARM BACK UP INTO THE 80S FOR HIGHS AND
LOWS INTO THE 50S, EXCEPT 60S ALONG THE EAST COAST METRO AREAS.
THE WEATHER WILL ALSO REMAIN MOSTLY DRY THIS NEW YEAR'S WEEKEND,
EXCEPT FOR A FEW ISOLATED SHOWERS ALONG THE EAST COAST METRO AREAS
MAINLY NEW YEAR'S EVE NIGHT AND NEW YEAR'S DAY.

ANOTHER COLD FRONT WILL THEN MOVE THROUGH SOUTH FLORIDA FOR THE
START OF THE FIRST WEEK OF THE NEW 2012 YEAR. BUT THIS FRONT WILL
BE DRY AND WILL JUST REINFORCE THE DRY WEATHER OVER SOUTH
FLORIDA...AND ALLOW FOR THE TEMPERATURES TO FALL BACK TO NEAR
NORMAL CONDITIONS.

MARINE...
THE WINDS TONIGHT WILL SWING TO A NORTHWEST DIRECTION BY MIDNIGHT
AS THE COLD FRONT MOVES THROUGH THE AREA. THE WIND SPEEDS WILL
INCREASE TO 15 TO 20 KNOTS IN THE GULF WATERS THIS EVENING INTO
TONIGHT. IN REST OF THE ATLANTIC WATERS...THE WIND SPEEDS WILL
INCREASE TO 15 TO 20 KNOTS BY MIDNIGHT TONIGHT AND REMAIN THERE
THROUGH WEDNESDAY MORNING.

THERE IS ALSO A NORTHWEST SWELL OF 1 TO 2 FEET THAT WILL WORK INTO
THE OFFSHORE GULF WATERS TONIGHT...AND A NORTHERLY SWELL OF 1 TO 2
FEET IN THE ATLANTIC WATERS LATE TONIGHT INTO WEDNESDAY. SO THE
SEAS WILL BUILD TO 5 TO 7 FEET IN THE PALM BEACH WATERS LATE
TONIGHT INTO WEDNESDAY...AND 4 TO 6 FEET IN REST OF THE ATLANTIC
WATERS. SO WILL BE PUTTING UP A SCEC FOR THE WINDS FOR ALL OF THE
WATERS AND A SCA CONDITION FOR THE SEAS IN THE PALM BEACH WATERS
AND OFFSHORE GULF WATERS FOR TONIGHT.

THE WINDS WILL THEN COME DOWN TO LESS THAN 15 KNOTS BY WEDNESDAY
EVENING...AND REMAIN BELOW 15 KNOTS THROUGH THE NEW YEAR'S EVE
WEEKEND WHILE SWINGING SLOWLY TO A EASTERLY DIRECTION. THIS WILL
ALLOW FOR THE SEAS TO FALL BELOW 6 FEET BY WEDNESDAY NIGHT AND
REMAIN BELOW 6 FEET THROUGH THE NEW YEAR'S WEEKEND IN BOTH THE
ATLANTIC AND GULF WATERS.

FIRE WEATHER...
A COLD FRONT WILL BE MOVING THROUGH SOUTH FLORIDA THIS EVENING.
BEHIND THE FRONT...MUCH DRIER AND COOLER WEATHER WILL WORK INTO
THE AREA FROM THE NORTH FOR WEDNESDAY INTO THURSDAY. THIS WILL
ALLOW FOR THE RELATIVE HUMIDITIES TO FALL INTO THE MID TO UPPER
20S OVER THE INTERIOR AREAS TO THE LOWER TO MID 30S ALONG THE
METRO AREAS OF SOUTH FLORIDA FOR WEDNESDAY. HOWEVER...THE ENERGY
RELEASE COMPONENT (ERC) HAS BEEN IN THE MID TO UPPER 20S OVER THE
LAST COUPLE OF DAYS AND SHOULD CONTINUE INTO WEDNESDAY. ALSO THE
20 FOOT WINDS WILL REMAIN LESS THAN 15 MPH FOR WEDNESDAY OVER THE
CWA. THEREFORE...WILL NOT BE ISSUING ANY FIRE WEATHER WATCHES OR
WARNINGS FOR SOUTH FLORIDA FOR WEDNESDAY...BUT WILL CONTINUE TO
MONITOR THE LATEST MODEL FORECAST ON THE ERC.
