Area forecast discussion, Aug 3, 3:02 PM EDT, 1 hour 45 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 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. && .PRELIMINARY POINT TEMPS/POPS...
