AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 1019 AM EDT TUE SEP 8 2015 .UPDATE... MID LEVEL TROUGH CONTINUES TO DRIFT NORTHWEST ACROSS THE NORTHEAST GULF OF MEXICO WITH ATLANTIC RIDGE BUILDING BACK TO THE WEST OVER SOUTH FLORIDA. THIS HAS RESULTED IN A CONTINUATION OF DEEP SOUTHERLY MOIST AIR BUT WITH SLIGHT WARMING ALOFT. THEREFORE, ACTIVITY WILL NOT BE AS ROBUST AS YESTERDAY BUT COULD STILL GET TORRENTIAL DOWNPOURS ESPECIALLY WHEREVER CONVERGENT BOUNDARIES MAY SET UP. SO WILL LEAVE MENTION OF FLOODING POTENTIAL IN THE HWO BUT WILL REMOVE STRONG WIND GUSTS DUE TO A LACK OF ANY DISCERNIBLE DRY LAYERS OBSERVED FROM THE 12Z MFL SOUNDING. KOB && .PREV DISCUSSION... /ISSUED 736 AM EDT TUE SEP 8 2015/ AVIATION... A DEEP SOUTHERLY FLOW OF TROPICAL AIR WILL INFLUENCE SOUTH FLORIDA THROUGH THE FORECAST PERIOD WITH SEA BREEZES DEVELOPING ALONG BOTH COASTS. THUNDERSTORMS WILL NOT BE QUITE AS ACTIVE AS YESTERDAY WITH SOME WARMING ALOFT AND WILL MOSTLY MOVE INLAND AWAY FROM THE TERMINALS. THUS, HAVE KEPT VCTS IN FOR ALL TAF SITES FOR THE LATE MORNING AND EARLY AFTERNOON. KOB PREV DISCUSSION... /ISSUED 306 AM EDT TUE SEP 8 2015/ .LATE SUMMER TIME WEATHER PATTERN CONTINUES ACROSS SOUTH FLORIDA THIS WEEK... SHORT TERM... LOW PRESSURE OVER THE NORTHEAST GULF OF MEXICO WILL CONTINUE TO MOVE NORTHWARD TODAY AND DISSIPATE OVER THE SOUTHEASTERN UNITED STATES TONIGHT ALLOWING FOR HIGH PRESSURE TO BUILD INTO THE FLORIDA PENINSULA FROM THE WESTERN ATLANTIC WATERS. THIS WILL ALLOW FOR THE WIND FLOW OVER SOUTH FLORIDA TO BE SOUTH/SOUTHEAST AND ALLOW FOR THE SEA BREEZES TO DEVELOP AND PUSH INLAND TODAY. THEREFORE...THE BEST COVERAGE OF SHOWERS AND THUNDERSTORMS TODAY WILL BE OVER THE INTERIOR AREAS OF SOUTH FLORIDA. THE HIGH WILL REMAIN OVER THE WESTERN ATLANTIC WATERS EXTENDING INTO CENTRAL FLORIDA FOR THE MIDDLE TO END OF THIS WEEK. THIS WILL KEEP SOUTH FLORIDA IN A EAST TO SOUTHEAST WIND FLOW FOCUSING THE SHOWERS AND THUNDERSTORM ACTIVITY OVER THE INTERIOR AND WEST COAST METRO AREAS EACH DAY. THEREFORE...THE HIGHEST POPS WILL BE OVER THE INTERIOR AND WEST COAST METRO AREAS EACH DAY THIS WEEK. LONG TERM... THE LONG RANGE MODELS ARE SHOWING A COLD FRONT TO MOVE SOUTHWARD INTO THE SOUTHEAST UNITED STATES THIS WEEKEND AND STALL OUT. THIS WILL PUSH THE HIGH SOUTHWARD INTO SOUTH FLORIDA THIS WEEKEND ALLOWING FOR THE WIND FLOW TO BECOME MORE SOUTHERLY ALONG WITH MORE DEEPER TROPICAL MOISTURE WORKING INTO THE AREA FROM THE SOUTH. THEREFORE...THE HIGHEST POPS WILL SHIFT TO THE NORTHERN AREAS OF SOUTH FLORIDA THIS WEEKEND BUT ALL OF SOUTH FLORIDA SHOULD SEE SCATTERED COVERAGE IN POPS. MARINE... THE WINDS WILL BE SOUTH TO SOUTHEAST TODAY BEFORE SWINGING MORE TO THE SOUTHEAST DIRECTION TONIGHT THROUGH REST OF THE WEEK. THE WIND SPEEDS WILL BE LESS THAN 10 KNOTS TODAY THROUGH REST OF THE WEEK. THIS WILL KEEP THE SEAS AT 2 FEET OR LESS IN BOTH THE ATLANTIC AND GULF WATERS OF SOUTH FLORIDA THROUGH THE WEEK. THEREFORE...BOATING CONDITIONS SHOULD BE GOOD ACROSS SOUTH FLORIDA WATERS OUTSIDE OF ANY SHOWERS OR THUNDERSTORMS. && .PRELIMINARY POINT TEMPS/POPS...
