AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
231 PM EDT THU JUN 11 2015

.SYNOPSIS...
HIGH PRESSURE CENTERED OVER THE ATLANTIC WILL BUILD INTO SOUTH
FLORIDA INTO EARLY NEXT WEEK...BRINGING SLIGHTLY DRIER CONDITIONS.
THUNDERSTORMS WILL BE FOCUSED OVER INTERIOR AND WESTERN PORTIONS
OF SOUTH FLORIDA.

&&

.SHORT TERM /TONIGHT THROUGH SUNDAY NIGHT/...
CI DEBRIS FROM OVERNIGHT CONVECTION HAS HELD ON IN SOUTH FLORIDA
INTO THE EARLY AFTERNOON...SUPPRESSING INSTABILITY AND
TEMPERATURES TO SOME DEGREE. THUS...TSTM CHANCES HAVE BEEN REDUCED
TODAY.

WEAK M/ULVL LOPRES OVER NORTH-CENTRAL GULF WILL GRADUALLY
RETROGRADE AND WEAKEN AS SUBTROPICAL RIDGE BUILDS IN FROM THE
EAST. EXPECT MORE SOUTHEASTERLY FLOW THROUGH THE SHORT
TERM...LEADING TO EVEN LOWER POPS ALONG ATLANTIC COAST...WITH
TYPICAL SUMMERTIME DIURNAL CONVECTION REMAINING SCATTERED AND
INLAND. OVERNIGHT BREEZE OFF THE ATLANTIC WILL KEEP MINIMA
WARM...NEAR 80F...WITH MAXIMA AREAWIDE IN THE UPPER 80S TO LOW
90S.

EASTERLY WIND INCREASE WILL RESULT IN MODERATE RISK FOR RIP
CURRENTS ON ATLANTIC BEACHES THROUGH THE WEEKEND.

.LONG TERM /MONDAY THROUGH WEDNESDAY NIGHT/...
RELATIVELY BENIGN CONDITIONS WILL PERSIST WELL INTO NEXT WEEK.
SUBTROPICAL RIDGING WILL CONTINUE TO DOMINATE WITH SCATTERED
AFTERNOON CONVECTION ANTICIPATED. OVERALL...FCST RNFL AMOUNTS WELL
BELOW NORMAL THROUGH THE PERIOD. TEMPS WILL BE NEAR/SLIGHTLY ABOVE
NORMAL.

&&

.AVIATION...
VFR CONDITIONS TO PREVAIL AT ALL SITES THROUGH THE NEXT 24 HOURS
OUTSIDE OF ANY CONVECTION THAT MAY DEVELOP. MUCH MORE STABLE LOW
AND MID LEVELS ALONG WITH PLENTY OF CLOUD COVER HAVE KEPT
CONVECTION FROM FORMING THUS FAR THIS AFTERNOON. LATEST VISIBLE
SATELLITE DOES SHOW SOME BREAKS IN THE CLOUDS ACROSS THE EAST
COASTAL AREAS BUT MAY FILL BACK IN SHORTLY WITH THICKER CIRRUS
MOVING IN FROM THE SOUTH. THEREFORE BELIEVE ANY CONVECTION THAT
DEVELOPS SHOULD BE CONFINED ACROSS THE INTERIOR AND MUCH LESS IN
COVERAGE THAN OVER THE LAST FEW DAYS.

&&

.MARINE...
HIGH PRESSURE STRENGTHENING OVER WESTERN ATLANTIC WILL BRING
PREDOMINANTLY EASTERLY WIND TO THE WATERS INTO EARLY NEXT
WEEK..ALTHOUGH SPEEDS SHOULD REMAIN 15 KT OR LESS.  SEAS WILL
REMAIN BELOW 4 FEET.
