AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE MIAMI FL
720 AM EDT FRI OCT 9 2015

.AVIATION...
THE EAST AND WEST COAST SEA BREEZES WILL DEVELOP LATE THIS MORNING
ALONG BOTH COASTS AND PUSH INTO THE INTERIOR AREAS BY THIS
AFTERNOON. THIS WILL ALLOW FOR THE WINDS OVER SOUTH FLORIDA TAF
SITES TO BE LIGHT AND VARIABLE THIS MORNING...BEFORE BECOMING
EASTERLY AT 5 TO 10 KNOTS THIS AFTERNOON OVER THE EAST COAST TAF
SITES AND WESTERLY AT 5 TO 10 KNOTS OVER KAPF TAF SITE. AS THE SEA
BREEZES PASSES THROUGH THE TAF SITES...THERE WILL BE A CHANCE OF
SHOWERS. HOWEVER...THE THREAT OF THUNDERSTORMS WILL BE OVER THE
INTERIOR AREAS THIS AFTERNOON. THE CEILING AND VIS SHOULD REMAIN
IN THE VFR CONDITIONS TODAY AT ALL OF THE TAF SITES...EXCEPT WHEN
A SHOWER PASSES OVER THE TAF SITES WHERE IT COULD FALL DOWN INTO
MVFR CONDITIONS.

.PREV DISCUSSION... /ISSUED 404 AM EDT FRI OCT 9 2015/

SHORT TERM (TODAY-SUNDAY)...
ASTRONOMICAL HIGH TIDES ALONG WITH THE LUNAR CYCLE WILL CONTINUE
THE THREAT OF MINOR STREET FLOODING ALONG THE ATLANTIC COAST
ESPECIALLY ALONG THE BARRIER ISLANDS. TIDES ARE RUNNING ABOUT A
FOOT ABOVE PREDICTED LEVELS AND HAVE BEEN ON THE RISE FOR THE PAST
COUPLE OF DAYS. THE SOUTHBOUND LANE ON INDIAN CREEK DRIVE IN
MIAMI BEACH WAS CLOSED LAST EVENING BETWEEN 7 AND 9 PM WHICH
COINCIDED WITH THE HIGH TIDE. DUE TO THESE COMBINING FACTORS, HAVE
DECIDED TO EXTEND THE COASTAL FLOOD ADVISORY THROUGH EARLY SUNDAY
AFTERNOON WITH THE NEW MOON OCCURRING NEXT TUESDAY. SO IN FACT,
MAY NOT HAVE EXTENDED THE STATEMENT LONG ENOUGH AND WILL CONTINUE
TO KEEP CLOSE TABS ON THE EVOLUTION OF THE HIGHER TIDES.

WEATHERWISE, A WEAK ZONAL FLOW PATTERN WILL EXIST ACROSS SOUTH
FLORIDA THROUGH EARLY SATURDAY WITH ALSO A WEAK SURFACE PRESSURE
GRADIENT. FORECAST SOUNDINGS SHOW THE PWAT WILL REMAIN AT OR JUST
BELOW 2" THROUGH THIS PERIOD SO EXPECT THE TYPICAL DIURNAL CYCLE
OF SHOWERS AND THUNDERSTORMS MAINLY DRIVEN BY SEA BREEZE AND
OUTFLOW BOUNDARIES WITH PLENTY OF SURFACE HEATING TAKING PLACE
DURING THE DAY.

ON SUNDAY, A MID/UPPER LEVEL TROUGH WILL MOVE ACROSS NORTH FLORIDA
AND THIS WILL BRING A DRIER AIRMASS ACROSS SOUTH FLORIDA BY SUNDAY
AFTERNOON WITH PWAT VALUES FORECAST TO DROP TO AROUND 1.5". FOR
THIS REASON, LOWERED THE POPS BELOW MOST GUIDANCE ALTHOUGH THE
BEST CHANCE COULD BE LATE MORNING AND EARLY AFTERNOON WITH THE
APPROACH OF A WEAK SURFACE BOUNDARY AND BEFORE THE DRIER AIR ALOFT
ARRIVES.

LONG TERM (MONDAY-THURSDAY)...
THE UPPER LOW WILL SLOWLY LIFT TO THE NORTHEAST EARLY NEXT WEEK
WITH THE PWAT REMAINING NEAR 1.5" THROUGH TUESDAY. MOISTURE WILL
RETURN BY THE MIDDLE TO THE END OF THE WEEK AS WEAK RIDGING ALOFT
OCCURS AND THE BOUNDARY LEVEL WINDS VEER TO THE SOUTHEAST AS
SURFACE HIGH PRESSURE BUILDS ACROSS THE SOUTHEAST STATES.

MARINE...
A SMALL NORTHEAST SWELL WILL CONTINUE TO SLOWLY DIMINISH OVER THE
ATLANTIC WATERS EAST OF PALM BEACH COUNTY TODAY WITH SEAS ALSO
SUBSIDING. SURFACE WINDS WILL BE LIGHT SOUTHEAST TO SOUTH TODAY
AND THEN VEER TO A WESTERLY DIRECTION LATE IN THE WEEKEND AND INTO
EARLY NEXT WEEK AS A SURFACE TROUGH APPROACHES AND MOVES ACROSS
THE SOUTH FLORIDA WATERS. SEAS WILL REMAIN BELOW ADVISORY LEVELS.
