NATIONAL WEATHER SERVICE MIAMI FL
314 PM EST SUN NOV 23 2014

...DRY WEATHER FOR MONDAY THEN A RETURN TO SHOWERS AND THUNDERSTORMS
FOR TUESDAY INTO WEDNESDAY..

...COOLER AND DRY CONDITIONS RETURN TO SOUTH FLORIDA LATE WEEK...

.SHORT TERM...
LOW PRESSURE WAS LOCATED OVER THE MISSISSIPPI VALLEY EARLY THIS
AFTERNOON WITH A WARM FRONT EXTENDING EAST INTO NORTH FLORIDA.
THE LOW WILL MOVE NORTHEAST INTO THE OHIO VALLEY TONIGHT WITH THE
WARM FRONT MOVING NORTH. THE LOW WILL ALSO PUSH A COLD FRONT EASTWARD
INTO NORTHERN FLORIDA BEFORE STALLING OUT ON MONDAY. THIS WILL
KEEP THE STEERING FLOW OVER SOUTH FLORIDA IN A SOUTHERLY DIRECTION
TONIGHT INTO MONDAY BRINGING IN SOME DRIER AIR TO THE AREA FROM THE
SOUTH. WEATHER WILL BE MAINLY DRY OVER SOUTH FLORIDA TONIGHT INTO
MONDAY EXCEPT FOR A FEW SHOWERS OVER THE NORTHEAST AREAS OF SOUTH
FLORIDA ON MONDAY AFTERNOON.

FOG IS ALSO EXPECTED TO FORM TONIGHT OVER THE INTERIOR AND WEST
COAST METRO AREAS AND COULD EVEN SPREAD INTO THE EAST COAST METRO
AREAS LATE TONIGHT INTO EARLY MONDAY MORNING ON THE SOUTHERLY WIND
FLOW. THE INTERIOR AREAS COULD EVEN SEE SOME DENSE FOG LATE
TONIGHT INTO EARLY MONDAY MORNING. THEREFORE...FOG HAS BEEN ADDED
TO THE FORECAST FOR LATE TONIGHT INTO EARLY MONDAY MORNING OVER
MOST OF SOUTH FLORIDA.

HIGH PRESSURE OVER THE CENTRAL UNITED STATES WILL MOVE SLOWLY SOUTHEAST
TOWARDS THE SOUTHEASTERN UNITED STATES ON TUESDAY. THIS IN TURN WILL
PUSH THE STATIONARY FRONT SOUTH INTO CENTRAL FLORIDA. AT THE SAME
TIME...MOISTURE OVER THE EASTERN CARIBBEAN SEA WILL ALSO BE MOVING
WEST NORTHWEST AND WILL GET PULLED UP INTO SOUTH FLORIDA AHEAD OF
THE FRONT. THIS WILL ALLOW FOR SCATTERED SHOWERS AND EVEN A FEW
THUNDERSTORM TO DEVELOP OVER SOUTH FLORIDA WITH THE BEST COVERAGE
OVER THE LAKE OKEECHOBEE REGION.

LOW PRESSURE WILL THEN DEVELOP OVER THE CENTRAL GULF OF MEXICO
TUESDAY NIGHT AND MOVE NORTHEAST ALONG THE STATIONARY FRONT OVER
CENTRAL FLORIDA WEDNESDAY MORNING INTO THE ATLANTIC WATERS WEDNESDAY
AFTERNOON. THE LOW WILL PUSH THE FRONT SOUTHWARD THROUGH SOUTH
FLORIDA ON WEDNESDAY. SHOWERS AND EVEN SOME THUNDERSTORMS WILL
CONTINUE TO AFFECT SOUTH FLORIDA TUESDAY NIGHT INTO WEDNESDAY OVER
SOUTH FLORIDA.

A MID LEVEL JET OF 50 KNOTS WILL ALSO BE MOVING THROUGH THE LAKE
OKEECHOBEE REGION LATE TUESDAY INTO WEDNESDAY. THIS MID LEVEL JET
WILL ALLOW FOR A FEW THUNDERSTORMS TO BECOME STRONG OVER SOUTH
FLORIDA WITH THE PRIMARY IMPACTS BEING GUSTY WINDS. SPC HAS ALSO
PUT SOUTH FLORIDA IN A MARGINAL RISK OF SEVERE WEATHER FOR LATE
TUESDAY NIGHT ESPECIALLY OVER THE LAKE OKEECHOBEE AREA.


.LONG TERM...
THE COLD FRONT WILL CONTINUE TO MOVE SOUTHWARD THROUGH THE FLORIDA
STRAITS AND INTO CUBA LATE THIS WEEK AS HIGH PRESSURE BUILDS INTO
THE SOUTHEASTERN UNITED STATES. THIS WILL ALLOW FOR A NORTHERLY
WIND FLOW ALONG WITH DRIER AND COOLER WEATHER OVER SOUTH FLORIDA
LATE THIS WEEK. THE COOLEST MORNING ACROSS SOUTH FLORIDA WILL BE
THANKSGIVING MORNING WHERE MOST OF SOUTH FLORIDA WILL BE IN THE
MID 40S TO LOWER 50S, EXCEPT LOWER TO MID 50S EAST COAST METRO
AREAS. THE WINDS WILL ALSO BE 5 TO 10 MPH OVER MOST OF SOUTH
FLORIDA...EXCEPT 10 TO 15 MPH OVER THE EAST COAST METRO AREAS
DURING THE EARLY MORNING HOURS OF THANKSGIVING. THIS WILL ALLOW
FOR THE WIND CHILLS TO FALL TO AROUND 40 OVER THE AREA WEST OF
LAKE OKEECHOBEE EARLY THANKSGIVING MORNING.

THE HIGH WILL SHIFT SLOWLY EAST INTO THE WESTERN ATLANTIC WATERS
NEXT WEEKEND ALLOWING FOR THE WINDS TO BECOME BREEZY FROM THE EAST
LEADING TO A THREAT OF RIP CURRENTS ALONG THE EAST COAST BEACHES
OF SOUTH FLORIDA. THE WEATHER WILL ALSO REMAIN DRY NEXT WEEKEND
OVER SOUTH FLORIDA.

THEREFORE...THE SCA HEADLINE WILL BE DROPPED FROM ALL OF SOUTH
FLORIDA WATERS FOR THE AFTERNOON PACKAGE...BUT MAY NEED TO BE PUT
BACK UP BY MIDDLE OF THE WEEK.

&&

.MARINE...
THE WINDS WILL REMAIN SOUTHERLY OVER SOUTH FLORIDA TONIGHT INTO
TUESDAY WITH WIND SPEEDS AT 15 KNOTS OR LESS. THIS WILL KEEP THE
SEAS BELOW 6 FEET IN BOTH THE ATLANTIC AND GULF WATERS OF SOUTH
FLORIDA. THE WINDS WILL QUICKLY BECOME NORTHERLY BEHIND THE
PASSAGE OF THE COLD FRONT MIDDLE OF THIS WEEK AS WIND SPEEDS
INCREASE TO 20 TO 25 KNOTS. THIS WILL ALLOW FOR THE SEAS IN BOTH
THE ATLANTIC AND GULF WATERS TO BUILD RAPIDLY TO 7 FEET OR HIGHER
LATE WEDNESDAY AFTERNOON INTO WEDNESDAY NIGHT BEHIND THE PASSAGE
OF THE COLD FRONT.
