AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
428 AM EST MON JAN 29 2007

.DISCUSSION...
A DRY COLD FRONT WAS MOVING SOUTH THROUGH CENTRAL FLORIDA EARLY
THIS MORNING. THIS FRONT WILL CONTINUE TO MOVE SOUTH AND THROUGH
THE CWA DURING THE MORNING HOURS. THE FRONT WILL BRING VERY DRY
AIR AT THE LOW LEVELS AND MUCH COOLER AIR TO THE AREA BY THIS
AFTERNOON.

THE SHORT RANGE MODELS CONTINUE TO SHOW THAT THE HIGH PRESSURE
OVER SOUTHEAST TEXAS EARLY THIS MORNING WILL CONTINUE TO MOVE
SOUTH AND EAST TOWARDS FLORIDA TODAY AND OVER NORTH FLORIDA
TONIGHT. THIS WILL ALLOW FOR THE WINDS OVER THE INTERIOR AREAS TO
BECOME LIGHT AND VARIABLE TONIGHT SETTING UP A GOOD RADIATIONAL
COOLING EVENT. THE ONLY FLY IN THE OINTMENT COULD BE SOME HIGH
CIRRUS CLOUDS THAT COULD MOVE INTO THE AREA LATE TONIGHT FROM THE
WEST REDUCING THE RADIATIONAL COOLING EVENT. HOWEVER WITH THE VERY
DRY AIR AT THE LOW LEVELS TODAY...LOW TEMPS COULD STILL GET DOWN
TO NEAR FREEZING CONDITIONS TOWARD SUNRISE TUESDAY. SO WILL KEEP
THE FREEZE WATCH UP FOR THE NORTHERN INTERIOR AREAS OF SOUTH
FLORIDA FOR TONIGHT...AND LET THE DAY SHIFT DETERMINE IF A FREEZE
WARNING MAY BE NEEDED FOR TONIGHT. THERE COULD EVEN BE SOME PATCHY
FROST OVER THE INTERIOR AREAS OF THE CWA TOWARD SUNRISE.

FOR REST OF CWA TONIGHT...THE SHORT RANGE MODELS DO TRY TO BRING
THE WINDS AROUND TO THE NORTHEAST TONIGHT ALLOWING FOR SOME
MOISTURE TO WORK INTO THE EAST COAST METRO AREAS. HOWEVER WITH THE
VERY DRY AIR OVER THIS AREA TODAY...THINK THAT DRAINAGE WILL SET UP
ALONG BOTH COASTS. SO HAVE WENT BELOW THE MAV GUIDANCE ABOUT 3 TO
5 DEGREES FOR TONIGHTS LOWS ALONG BOTH METRO COASTS OF THE
CWA...WITH UPPER 30S WELL INLAND TO MID TO UPPER 40S NEAR THE
COASTLINE.

THE HIGH WILL THEN MOVE SLOWLY TO THE EAST THROUGH THURSDAY...AS
ANOTHER LOW PRESSURE DEVELOPS IN THE WESTERN GULF OF MEXICO. THIS
WILL ALLOW FOR THE WINDS TO SWING TO A EASTERLY DIRECTION AND
ALLOW FOR A WARM UP TO NEAR NORMAL TEMPS FOR THE CWA BY WEDNESDAY.
THE WX WILL ALSO REMAIN DRY THROUGH WEDNESDAY OVER THE CWA.

.EXTENDED FORECAST...
THE LOW PRESSURE SHOULD THEN MOVE EAST THROUGH NORTH FLORIDA LATE
THIS WEEK ALLOWING FOR THE WINDS TO SWING TO SOUTHERLY DIRECTION
OVER THE AREA...AND ALLOW FOR TEMPS TO WARM UP TO ABOVE NORMALS
FOR THIS TIME OF YEAR. THERE COULD ALSO BE SOME SHOWERS AROUND
LATE THIS WEEK DUE TO THE INCREASE IN MOISTURE OVER THE AREA. SO
HAVE KEPT THE SLIGHT CHANCE OF SHOWERS IN THE FORECAST FOR LATE
THIS WEEK OVER THE CWA.

THE FRONT IS THEN FORECAST TO MOVE THROUGH THE CWA THIS WEEKEND
KEEPING THE MOISTURE OVER THE AREA. SO HAVE KEPT THE CHANCE OF
POPS IN THE FORECAST FOR SATURDAY AND SLIGHT CHANCE OF SHOWERS FOR
SUNDAY. TEMPS SHOULD ALSO BE NEAR NORMAL FOR THIS TIME OF YEAR
THIS WEEKEND.

&&

.AVIATION...
GAIN...MODELS GROSSLY OVER-ESTIMATED WINDS OVERNIGHT. WINDS ARE 5
KT OR LESS EVERYWHERE WITH EVEN CALM WINDS AT TMB AND APF. WINDS
WILL PICK UP OUT OF THE N-NW AFTER SUNRISE TO AROUND 10 KT. MOSTLY
CLEAR SKIES WILL PREVAIL ACROSS THE AREA...EXCEPT SCT035 AT APF
MAINLY THIS MORNING. SO NO AVIATION CONCERNS.

&&

.MARINE...
THE WINDS THIS MORNING HAVE BEEN COMING FROM THE WEST TO NORTHWEST
AROUND 15 TO 20 KNOTS. THESE WINDS SHOULD SWING TO A NORTHERLY
DIRECTION BY TONIGHT AND SLOWLY DECREASE TO AROUND 5 TO 10 KNOTS
BY MIDNIGHT. THE WINDS WILL THEN REMAIN OUT OF THE NORTH AT 5 TO
10 KNOTS ON TUESDAY BEFORE SWINGING TO A EASTERLY DIRECTION BY WEDNESDAY.

THIS WILL ALLOW FOR THE SEAS IN THE GULF STREAM TO BE UP TO 13
FEET THIS MORNING BEFORE SLOWLY DECREASING TO LESS THAN 7 FEET BY
LATE THIS EVENING. SO WILL KEEP A SCA UP FOR THE GULF STREAM FOR
SEAS THROUGH EARLY THIS EVENING.

FOR REST OF THE CWA WATERS...PLAN ON HAVING A SCEC UP THIS MORNING
FOR THE WINDS.

&&

.FIRE WEATHER...
THE DEW POINTS BEHIND THE DRY COLD FRONT WERE IN THE 20S TO 30S.
THESE DEW POINTS WILL WORK INTO THE CWA THIS MORNING INTO EARLY
AFTERNOON. TEMPS WILL ALSO WARM UP INTO THE 60S OVER THE CWA. THIS
WILL ALLOW FOR THE RELATIVE HUMIDITIES TO FALL DOWN INTO THE 20S
OVER MOST OF THE CWA THIS AFTERNOON. SO WILL UPGRADE THE FIRE
WEATHER WATCH TO A RED FLAG WARNING FOR ALL OF THE CWA FOR THIS
AFTERNOON.

THE RELATIVE HUMIDITIES ON TUESDAY AFTERNOON COULD FALL DOWN TO
THE LOWER 30S AROUND THE LAKE OKEECHOBEE AREA FOR 3 TO 4 HOURS.
WILL LET THE DAY SHIFT LOOK AT THIS MORE CLOSELY TO SEE IF A FIRE
WEATHER WATCH NEEDS TO BE PUT UP FOR THIS AREA FOR TUESDAY
AFTERNOON.
