AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
952 AM EDT THU AUG 31 2006

.UPDATE...NO MAJOR CHANGES TO MORNING UPDATES AS EVERYTHING PRETTY
MUCH STATUS QUO. THE ONLY EXCEPTION IS THE MORNING CLOUDINESS
ACROSS THE NW PORTION OF THE CWA WHERE TEMPS HAVE BEEN HELD DOWN A
FEW DEGREES. SO WILL LOWER MAX TEMPS THERE A NOTCH. T.S. ERNESTO
CONTINUES TO MOVE AWAY FROM S FLA BUT TRAILING TROUGH FROM THE
SYSTEM DRAPES ACROSS S CENT FLA AND THIS AS ADVERTISED IN EARLIER
DISCUSSION WILL BE FOCUS MECHANISM FOR CONVECTION THROUGHOUT THE
DAY. THE 12Z MFL SOUNDING SHOWS ATMOSPHERE NOT QUITE AS TROPICAL
AS 12 TO 24 HOURS AGO AND HAS DESTABILIZED SUBSTANTIALLY ALTHOUGH
50H TEMP IS NOT UNUSUALLY COOL. STILL, LOOKING AT THE
DESTABILIZING FACTOR AND SUBSTANTIAL HEATING IN MORE CLOUD FREE
ZONE OVER A LARGE PART OF THE REGION WILL ONLY ENHANCE CONVECTIVE
ACTIVITY BY LATE THIS MORNING INTO THE AFTERNOON. AND AS ALREADY
INDICATED EARLIER IN ADDITION TO THE MORNING SOUNDING STEERING
FLOW REMAINS SW SO ANYTHING THAT DOES DEVELOP WILL MOVE TOWARD THE
E CST REGION. THE SW STEERING FLOW IS STRONG ENOUGH THAT SEA
BREEZE ALONG THE E CST IS NOT FORECAST SO THIS SHOULD PREVENT ANY
CONVECTION FROM BECOMING STRONG TO SEVERE SO ONLY LOCALLY HEAVY
RAINFALL IS ANTICIPATED.

.PREV DISCUSSION...
DISCUSSION...

THURSDAY THROUGH FRIDAY...ERNESTO IS BACK OVER WATERS AND MOVING FARTHER
AWAY FROM SOUTH FLORIDA. THIS SHOULD MEAN BETTER WX CONDS...(WELL,
IN GENERAL IT DOES). HOWEVER..A TROUGH EXTENDING FROM THE
CIRCULATION SOUTHWESTWARD ACROSS SOUTH-CENTRAL FLORIDA AND
NORTHERN PORTION OF SOUTH FLORIDA WILL PLAY AN IMPORTANT ROLE IN
OUR WX CONDS TODAY. THIS TROUGH WILL SERVE AS THE FOCUSING
MECHANISM FOR SHWRS/TSTMS TO DEVELOP THIS AFTERNOON. A MID/UPPER
LEVEL TROUGH WILL DIG SOUTH DOWN THE MISSISSIPPI VALLEY TO CENTRAL
GULF OF MEX. THIS WILL HELP TO DESTABILIZE UPPER ATMOSPHERE
ENHANCING CONVECT.SOUTHWESTERLY STEERING FLOW WILL THEN ADVECT ANY
CONVECTIVE ACTIVITY EAST OVER ERN METRO AREAS. WILL INDICATE
LIKELY POPS THIS AFTERNOON. ALTHOUGH ERNESTO WILL PROBABLY BE
INLAND AGAIN OVER EASTERN SEABOARD BY FRIDAY...THE TROUGH
EXTENDING FROM THE CIRCULATION WILL STILL EXTEND SOUTHWARD
REMAINING CLOSE TO OUR AREA AND WITH UPPER LEVEL CONDITIONS
REMAINING VIRTUALLY UNCHANGED...WILL LOWER POPS ONLY SLIGHTLY FOR FRIDAY.

EXTENDED...ALTHOUGH ERNESTO WILL BECOME EXTRATROPICAL AND RAPIDLY MOVE
NORTHEASTWARD...A LOW LEVEL TROUGH/BOUNDARY (SUGGESTED BY GFS)
WILL LINGER ACROSS SOUTH FLORIDA AND WILL CONTINUE TO BE THE
FOCUSING MECHANISM FOR CONVECTION. THEREFORE WILL INDICATE DAILY
AFTERNOON SHWRS/TSTMS ESPECIALLY SATURDAY WITH A RETURN TO MORE
CLIMO CONDS THEREAFTER.

AVIATION...
TROPICAL STORM ERNESTO CONTINUES TO MOVE NORTHEAST JUST OFF THE EAST
FLORIDA COAST. ANY LINGERING OUTER RAINBANDS ARE NOW MAINLY OVER THE
LOCAL ATLANTIC WATERS...WITH ALL LOCAL TERMINALS UNDER VFR
CONDITIONS...ALTHOUGH THERE IS A CEILING NEAR TEN THOUSAND FEET AT
MOST TERMINALS. VFR CONDITIONS SHOULD CONTINUE THROUGH EARLY TO MID
MORNING. THEREAFTER...WITH LINGERING TROPICAL MOISTURE OVER SOUTH
FLORIDA AND SOUTHWESTERLY LOW LEVEL WINDS...THE FAVORED AREAS FOR
CONVECTION THIS AFTERNOON WILL BE THE EAST COAST OF SOUTH FLORIDA.
SO THERE WILL BE PERIODS OF IFR CONDITIONS POSSIBLE OVER THE EAST
COAST TERMINALS THIS AFTERNOON AND EVENING...ESPECIALLY PBI.

MARINE...
WL KEEP SCEC OVER NORTHERN OFFSHORE ATLANTIC WATERS THROUGH THIS
AFTERNOON AS WINDS COULD RANGE BETWEEN 15 TO 20 KTS AND SEAS UP TO
6 FEET DURING THE MORNING HOURS. REST OF THE WATERS CONDS SHOULD
REMAIN BELOW SCEC CRITERIA THROUGH THE END OF THE FORECAST PERIOD.

FIRE WEATHER...
NO CONCERNS AT THIS TIME.
