AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE MIAMI FL
206 PM EDT TUE AUG 14 2012

.SHORT TERM...TONIGHT THROUGH FRIDAY...AN UPPER LEVEL RIDGE SHOULD
CONTINUE TO EXTEND FROM THE GULF OF MEX AND ACROSS THE PENINSULA,
WHILE THE LOW LEVEL ATLANTIC RIDGE WILL CONTINUE JUST NORTH OF THE
LOCAL AREA ACROSS CENTRAL FLORIDA. WHILE THE UPPER RIDGE WILL
CONTRIBUTE TO LIMIT WIDESPREAD PRECIP ACTIVITY BY WAY OF MODERATE
SUBSIDENCE, SOMEWHAT DEEPER EASTERLIES AROUND THE BASE OF THE
SURFACE ATLANTIC RIDGE WILL HELP TO TRANSPORT MOISTURE FROM THE
TROPICAL ATLANTIC OVER SOUTH FLORIDA. THIS MOISTURE, COMBINED WITH
LOCAL FACTORS SUCH AS SEA/LAKE BREEZES AND DIURNAL HEATING, WILL
LIKELY LEAD TO THE FORMATION OF DAILY AFTERNOON SCT SHWRS/TSTMS
ACROSS INLAND AREAS. ISOLATED TO WIDELY SCT NIGHTTIME/EARLY
MORNING ACTIVITY COULD ALSO OCCUR ALONG THE EAST COAST AND
ATLANTIC WATERS.

NEAR SEASONAL AFTERNOON TEMPS SHOULD CONTINUE TO BE EXPECTED ALONG COASTAL
AREAS DURING THIS PERIOD, BUT COULD SOAR TO THE MID 90S ACROSS
PORTIONS OF THE INTERIOR. HEAT INDICES WILL LIKELY RUN AT OR ABOVE
105 DEGREES EACH DAY.

.LONG TERM...SATURDAY THROUGH TUESDAY...ALTHOUGH THE UPPER RIDGE
MAY FINALLY MOVE OUT OF THE AREA...THE SURFACE RIDGE SHOULD REMAIN
JUST NORTH OF THE REGION WITH A MORE OR LESS WELL ESTABLISHED LOW
LEVEL EASTERLY FLOW ACROSS SOUTH FLORIDA. NO SIGNIFICANT CHANGES
IN THE CURRENT WEATHER PATTERN SHOULD BE EXPECTED WITH SCATTERED
AFTERNOON SHWR/TSTM ACTIVITY MAINLY ACROSS INTERIOR AREAS AND ISOLATED
TO LOW SCT NIGHTTIME/EARLY MORNING ACTIVITY ALONG COASTAL AREAS
AND ADJACENT WATERS. NO SIGNIFICANT CHANGES EXPECTED IN
TEMPERATURES EITHER.
