.PREV DISCUSSION... /ISSUED 552 PM EDT WED AUG 3 2011/

UPDATE...
THE LATEST FORECAST ON FROM THE NATIONAL HURRICANE CENTER ON
TROPICAL STORM EMILY NOW MOVES HIM THROUGH THE NORTHERN BAHAMA
ISLANDS ON SATURDAY INSTEAD LATE FRIDAY NIGHT. THIS WILL DELAY THE THREAT
OF THE TROPICAL STORM FORCE WINDS UNTIL SATURDAY FOR THE ATLANTIC
WATERS OF SOUTH FLORIDA. THEREFORE...THE POSSIBLE OF TROPICAL
STORM FORCE WINDS WORDING WILL CONTINUE FOR ALL OF SOUTH FLORIDA
ATLANTIC WATERS ON SATURDAY...BUT WILL REMOVE THE POSSIBLE
TROPICAL STORM FORCE WINDS WORDING FROM THE ATLANTIC WATERS FRIDAY
NIGHT.

THE CONE OF UNCERTAINLY OF TROPICAL STORM EMILY STILL COVERS THE
EASTERN PORTION OF SOUTH FLORIDA WHICH INCLUDES THE METRO AREAS OF
PALM BEACH...BROWARD...AND MIAMI-DADE COUNTIES. THEREFORE...PLEASE
REFER TO THE NATIONAL HURRICANE CENTER PRODUCTS FOR THE LATEST
INFORMATION ON EMILY.

UPDATE...54/BNB

PREV DISCUSSION... /ISSUED 302 PM EDT WED AUG 3 2011/

DISCUSSION...A TROUGH PUSHING OFF THE EAST COAST IS BRINGING
IN A BIT OF DRIER AIR ALOFT, ALTHOUGH THIS IS MUCH MORE
SUBSTANTIAL OVER CENTRAL AND NORTH FLORIDA. MEANWHILE, A SURFACE
RIDGE AXIS EXTENDS FROM THE WESTERN ATLANTIC INTO THE KEYS.
TEMPERATURES ALOFT REMAIN RELATIVELY WARM, BUT WE STILL
ANTICIPATE THE DEVELOPMENT OF A FEW STRONG THUNDERSTORMS THIS
AFTERNOON. FLOW REMAINS WEST-SOUTHWESTERLY ALOFT, WHILE THE SEA
BREEZES ARE SLOWLY MOVING INLAND ON EACH COASTLINE. OVERALL, THIS
WILL FAVOR STORM MOVEMENT TOWARD THE EAST/SOUTHEAST. SHOWERS AND
THUNDERSTORMS WILL DIMINISH EARLY THIS EVENING, WITH JUST
ISOLATED ACTIVITY PERSISTING OVERNIGHT, MAINLY OVER THE WATERS.
AS THE LAND BREEZE BECOMES ESTABLISHED TONIGHT, SOME PATCHY SMOKE
MAY MOVE INTO EASTERN BROWARD AND EASTERN MIAMI DADE COUNTIES.

AN UPPER LEVEL RIDGE WILL REMAIN OVER THE REGION THURSDAY INTO
FRIDAY, ALTHOUGH SUFFICIENT LOW LEVEL MOISTURE COMBINED WITH
DAYTIME HEATING AND INSTABILITY WILL AGAIN RESULT IN SCATTERED
SHOWERS AND THUNDERSTORMS EACH AFTERNOON. THE INTERIOR AND
WESTERN SECTIONS WILL LIKELY SEE THE HIGHEST COVERAGE AS THE
UPPER LEVEL FLOW BECOMES MORE NORTHEASTERLY. CONVECTION MAY BE
FURTHER LIMITED OVER EASTERN SECTIONS ON FRIDAY AFTERNOON DUE TO
SUBSIDENCE IN ADVANCE OF EMILY.

THE FORECAST FOR FRIDAY NIGHT THROUGH EARLY SUNDAY REMAINS HIGHLY
UNCERTAIN, DEPENDENT ON THE ULTIMATE TRACK AND INTENSITY OF
EMILY. THE LATEST OFFICIAL TRACK FROM THE NATIONAL HURRICANE
CENTER HAS MUCH OF SOUTH FLORIDA IN THE CONE OF UNCERTAINTY.
OVERALL, THE MODELS HAVE RECENTLY TRENDED A BIT FURTHER WESTWARD
WITH THE TRACK. HOWEVER, THE NEXT 24 HOURS WILL BE CRITICAL AS
THE SYSTEM INTERACTS WITH HISPANIOLA. IF IT MAINTAINS ITSELF, BUT
REMAINS RATHER WEAK, CONTINUED MOVEMENT TO THE WEST (RATHER THAN
NORTHWEST) IS MORE LIKELY. INTERESTS ACROSS SOUTH FLORIDA SHOULD
CONTINUE TO MONITOR THE SITUATION FOR FURTHER UPDATES ON TROPICAL
STORM EMILY.

THE NEXT UPPER TROUGH WILL MOVE OFF THE EASTERN SEABOARD EARLY
NEXT WEEK, WHICH WILL HELP LIFT EMILY TO THE NORTHEAST. THE
TROUGH WILL AGAIN RESULT IN A WESTERLY FLOW OVER THE LOCAL AREA
WITH SCATTERED SHOWERS AND THUNDERSTORMS CONCENTRATING TOWARDS
THE INTERIOR AND EAST COAST.

AVIATION...RECENT SATELLITE IMAGERY...RADAR RETURNS AND WIND
OBSERVATIONS INDICATE THAT THE EAST AND WEST COAST SEA BREEZES
ARE BECOMING ESTABLISHED...BUT THE EAST COAST SEA BREEZE HAS NOT
PENETRATED TO ALL THE EAST COAST TAF SITES THUS FAR BUT IS
EXPECTED TO. ALL TERMINALS ASSIGNED VCTS THIS AFTERNOON TO EARLY
EVENING, SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS EXPECTED
LATER THIS AFTERNOON TO EARLY EVENING WITH BRIEF PERIODS OF
MVFR/IFR CONDITIONS POSSIBLE ALL SOUTH FLORIDA TERMINALS WITH
OCCURRENCE OF ANY SHOWERS AND THUNDERSTORMS AT THE TAF SITES. A
WEAK SOUTH TO SOUTHWEST WIND FLOW EXPECTED TO PREVAIL ACROSS THE
REGION TONIGHT INTO THURSDAY.

MARINE...WINDS WILL REMAIN GENERALLY SOUTHERLY ON THURSDAY,
BEFORE BECOMING MORE EASTERLY ON FRIDAY. SEAS WILL REMAIN 3 FEET
OR LESS. TROPICAL STORM EMILY MAY AFFECT THE ATLANTIC MARINE
ZONES FRIDAY NIGHT INTO SATURDAY WITH TROPICAL STORM CONDITIONS
POSSIBLE. PLEASE REFER TO THE LATEST INFORMATION AND FORECASTS ON
TROPICAL STORM EMILY FROM THE NATIONAL HURRICANE CENTER.

FIRE WEATHER...RELATIVE HUMIDITIES WILL REMAIN ABOVE CRITICAL
THRESHOLDS THROUGH THE WEEK WITH NO SIGNIFICANT CONCERNS,
ALTHOUGH LOCAL BRUSH FIRES MAY RESULT IN AREAS OF SMOKE.
