AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL

...CHANCE OF NEEDED RAINFALL THROUGH THE WEEK ACROSS SOUTH FLORIDA...

.DISCUSSION...
A STATIONARY FRONT OVER NORTH FLORIDA WILL SLOWLY MOVE SOUTH TONIGHT
INTO CENTRAL FLORIDA ALLOWING FOR THE STEERING FLOW OVER THE CWA
TO REMAIN IN A SOUTHWEST DIRECTION...AND KEEP THE DEEP TROPICAL
MOISTURE IN PLACE OVER THE AREA. WITH THE TROPICAL MOISTURE AND
THE PARTLY CLOUDY SKIES OVER THE SOUTH FLORIDA THIS AFTERNOON INTO
THIS EVENING...PLAN ON KEEPING A CHANCE OF POPS OVER THE CWA WITH
THE HIGHEST POPS OVER THE NORTHERN AREAS. THE ATMOSPHERE IS ALSO
UNSTABLE THIS AFTERNOON ALLOWING FOR THE POSSIBILITY OF SOME
THUNDERSTORMS ESPECIALLY WHERE THE SEA BREEZES AND LAKE BREEZE
COLLIDE. SO WILL CONTINUE THE THREAT OF THUNDER FOR THE AREA
THROUGH THIS EVENING.

THE LINE OF SHOWERS AND THUNDERSTORMS OVER THE NORTHEAST GULF OF
MEXICO IS ALSO FORECAST BY THE SHORT RANGE MODELS TO MOVE EAST
SOUTHEAST TOWARDS CENTRAL FLORIDA TONIGHT...HOWEVER...THE SOUTHERN
PORTION OF THE LINE COULD WORK INTO THE NORTHERN PORTION OF THE
CWA LATE TONIGHT. SO WILL CONTINUE THE CHANCE OF POPS OVER THE
WEST COAST METRO AREAS WITH SLIGHT CHANCE OF POPS OVER REST OF THE
CWA FOR THE OVERNIGHT HOURS TONIGHT.

THERE COULD ALSO BE SOME PATCHY TO AREAS OF FOG OVER THE INTERIOR
AND EAST COAST METRO AREAS LATE TONIGHT ESPECIALLY IF THE SKIES
REMAIN MORE CLEAR AND THE LINE OF SHOWERS AND STORMS STAYS MORE
INTO CENTRAL FLORIDA. SO AT THIS TIME HAVE ADDED PATCHY FOG
WORDING TO THE INTERIOR AND EAST COAST METRO AREAS ZONES FOR LATE
TONIGHT...AND WILL LET THE EVENING CREW LOOK MORE CLOSELY AT THE
FOG POTENTIAL FOR LATE TONIGHT.

THE TROPICAL MOISTURE WILL REMAIN IN PLACE OVER THE CWA ON TUESDAY
AS THE STATIONARY FRONT WASHES OUT OVER CENTRAL FLORIDA. THE
STEERING FLOW WILL ALSO BE MORE SOUTHERLY OVER THE CWA DURING THIS
TIME. SO WILL CONTINUE THE CHANCE OF POPS ALONG WITH THE THUNDER
WORDING OVER THE CWA FOR TUESDAY. HOWEVER...THE HIGHEST POPS WILL
BE OVER THE LAKE OKEECHOBEE AREA.

HIGH PRESSURE WILL THEN BUILD INTO SOUTH FLORIDA FROM THE KEYS
MIDDLE OF THIS WEEK ALLOWING FOR SOME DRIER AIR TO WORK INTO THE
CWA. SO THE POPS WILL BE MORE ISOLATED TO LOW END SCATTERED RANGE
WITH THE HIGHS POPS OVER THE INTERIOR AREAS.

.EXTENDED FORECAST...
THE HIGH WILL THEN GET PUSH EAST INTO THE WESTERN ATLANTIC WATERS
LATE THIS WEEK...AS ANOTHER TROUGH OF LOW PRESSURE MOVES FROM THE
WESTERN UNITED STATES EASTWARD AND INTO THE EASTERN UNITED STATES.
THIS WILL ALLOW FOR ANOTHER COLD FRONT OVER THE NORTHWEST UNITED
STATES TO MOVE SOUTHEAST AND THROUGH SOUTH FLORIDA BY END OF THIS
WEEK BRINGING ANOTHER AROUND OF SHOWERS AND THUNDERSTORMS TO THE
AREA.

THE LATEST LONG RANGE MODELS ARE ALSO SHOWING THAT THERE COULD BE
A MID TO UPPER LEVEL JET COMING THROUGH THE CWA DURING THIS TIME.
THIS COULD LEAD TO A FEW STRONG STORMS WITH THE PASSAGE OF THE
FRONT ON FRIDAY. SO WILL CONTINUE TO MONITOR THE LATEST MODEL RUNS
FOR THE POSSIBLE OF STRONG STORMS ON FRIDAY AND FINE TUNE THE
DETAILS AS THE EVENT GETS CLOSER.

HIGH PRESSURE SHOULD THEN BUILD INTO SOUTH FLORIDA FROM THE NORTH
BEHIND THE FRONT FOR NEXT WEEK ALLOWING FOR DRY WEATHER ACROSS THE
CWA.

&&

.MARINE...
THE WINDS WILL BE FROM THE SOUTHERLY DIRECTION THIS AFTERNOON INTO
TUESDAY BEFORE SWINGING BACK EAST ON WEDNESDAY. THE SPEEDS WILL ALSO
REMAIN BELOW 15 KNOTS WHICH IN TURN WILL KEEP THE SEAS BELOW 6
FEET IN BOTH THE ATLANTIC AND GULF WATERS. SO BOATING CONDITIONS
WILL BE GOOD OUTSIDE OF ANY SHOWERS OR THUNDERSTORMS.

&&

.FIRE WEATHER...
THE RELATIVE HUMIDITIES ACROSS SOUTH FLORIDA WILL REMAIN WELL
ABOVE THE 35 PERCENT CRITICAL VALUE THIS AFTERNOON INTO
WEDNESDAY DUE TO THE TROPICAL MOISTURE IN PLACE. SO NO PROBLEMS
WITH THE FIRE WEATHER AT THIS TIME OVER SOUTH FLORIDA THROUGH
WEDNESDAY.
