AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 230 PM EDT WED JUL 15 2009 ...SCATTERED SHOWERS AND THUNDERSTORMS CONTINUE THROUGH THE WEEKEND... .DISCUSSION... THE EAST AND WEST COAST SEA BREEZES WERE DEVELOPING ALONG BOTH COAST EARLY THIS AFTERNOON...AND SHOULD PUSH SLOWLY INLAND THROUGH THE AFTERNOON AND EVENING HOURS. SHOWERS AND THUNDERSTORMS SHOULD ALSO CONTINUE TO DEVELOP ALONG BOTH SEA BREEZES THROUGH THE EVENING HOURS. SO WILL CONTINUE WITH THE SCATTERED POPS OVER THE CWA THIS AFTERNOON WITH THE HIGHEST POPS AGAIN OVER THE INTERIOR AREAS. THE SHOWERS AND THUNDERSTORMS SHOULD DISSIPATE THIS EVENING AS THE HEATING OF THE DAY IS LOST WITH THE HIGHEST POPS AGAIN OVER THE LAKE OKEECHOBEE AREA. THERE COULD ALSO BE A FEW SHOWERS OR THUNDERSTORMS THAT COULD WORK INTO THE EAST COAST METRO AREAS TONIGHT FROM THE ATLANTIC WATERS...DUE TO THE LIGHT SOUTHEAST TO SOUTH WIND FLOW AROUND THE HIGH PRESSURE SYSTEM THAT EXTENDS FROM THE WESTERN ATLANTIC WATERS INTO THE LAKE OKEECHOBEE AREA. THE HIGH WILL REMAIN NEARLY STATIONARY THURSDAY INTO FRIDAY ALLOWING FOR THE LIGHT SOUTHEAST TO SOUTH WIND FLOW TO CONTINUE OVER SOUTH FLORIDA. THIS WILL ALSO ALLOW FOR THE SEA BREEZES TO DEVELOP ALONG BOTH COAST EACH DAY AND PUSH INLAND SLOWLY. AT THE SAME TIME...THE WATER VAPOR SATELLITE IMAGES SHOW ANOTHER ROUND OF DEEPER MOISTURE OVER THE CENTRAL BAHAMA ISLANDS EARLY THIS AFTERNOON. THIS DEEPER MOISTURE SHOULD WORK INTO SOUTH FLORIDA ON THURSDAY INTO FRIDAY...AS IT MOVES ROUND THE WESTERN EDGE OF THE HIGH PRESSURE SYSTEM. SO WILL RAISE THE POPS UP TO HIGH IN CHANCE CAT FOR THE INTERIOR AND NORTHEAST AREAS AND CHANCE CAT FOR REST OF THE CWA FOR THURSDAY AND FRIDAY. .EXTENDED FORECAST... THE RIDGE OF HIGH PRESSURE WILL REMAIN OVER SOUTH FLORIDA THIS WEEKEND INTO EARLY NEXT WEEK...AS A TROUGH OF LOW PRESSURE DEVELOPS OVER THE CENTRAL UNITED STATES SOUTHWARD INTO THE CENTRAL GULF OF MEXICO. THIS WILL ALLOW FOR A SOUTH TO SOUTHWEST STEERING FLOW OVER THE CWA THIS WEEKEND INTO EARLY NEXT WEEK OVER THE CWA. AT THE SAME TIME...A TROPICAL WAVE OVER THE FAR EASTERN ATLANTIC WATERS WILL MOVE WEST TO NORTHWEST TOWARDS SOUTH FLORIDA THROUGH THE WEEKEND...BRINGING IN SOME DRIER AIR TO THE AREA FOR THIS WEEKEND. THE TROPICAL WAVE COULD THEN MOVE INTO SOUTH FLORIDA EARLY NEXT WEEK ALLOWING FOR DEEPER TROPICAL MOISTURE TO WORK INTO THE AREA. SO HAVE KEPT THE POPS IN THE SLIGHT CHANCE TO LOW END CHANCE CAT THIS WEEKEND FOR SOUTH FLORIDA, THEN THE HIGH IN CHANCE CAT FOR EARLY NEXT WEEK. && .AVIATION... THE EAST AND WEST COAST SEA BREEZES HAVE DEVELOPED EARLY THIS AFTERNOON ALONG BOTH COAST. THE SEA BREEZES HAS PUSH WEST OF THE THE EAST COAST TAF SITES EXCEPT FOR KPBI AND THE WEST COAST SEA BREEZE HAS PUSH EAST OF KAPF. SO HAVE SHOWN THIS IN THE WIND FIELD AND KEPT VCSH AT ALL OF THE TAF SITES, EXCEPT FOR KPBI WHICH WILL BE IN THE VCTS UNTIL 23Z. THE WEATHER SHOULD BE DRY AFTER 15/23Z TONIGHT AS MOST OF THE ACTIVITY SHOULD BE INLAND OF THE TAF SITES. THERE COULD BE A FEW SHOWERS OR THUNDERSTORMS LATE TONIGHT FOR THE EAST COAST TAF SITES...BUT THE COVERAGE SHOULD BE VERY SMALL. SO HAVE LEFT IT OUT OF THE EAST COAST TAF SITES. THE WIND SPEEDS SHOULD BE LESS THAN 5 KNOTS FROM THE SOUTHEAST DIRECTION WITH VFR CONDITIONS AT ALL OF THE TAF SITES. && .MARINE... THE WINDS OVER ALL OF THE SOUTH FLORIDA WATERS WILL BE LESS THAN 10 KNOTS TONIGHT THROUGH THIS WEEKEND MAINLY FROM THE SOUTHEAST TO SOUTH DIRECTION. THIS WILL KEEP THE SEAS BELOW 2 FEET. SO BOATING WEATHER SHOULD BE GOOD OUTSIDE OF THE SHOWERS AND THUNDERSTORM ACTIVITY. && .FIRE WEATHER... THE RELATIVE HUMIDITIES WILL BE ABOVE THE 35 PERCENT CRITICAL VALUE THROUGH THE WEEKEND. SO NO PROBLEMS WITH THE FIRE WEATHER PRODUCTS THROUGH THE WEEKEND. && .PRELIMINARY POINT TEMPS/POPS...
