SOUTH FLORIDA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 140 PM EDT SUN AUG 8 2004 .DISCUSSION...THE STATIONARY FRONT WAS STILL LOCATED OVER SOUTH CENTRAL FLORIDA THIS MORNING...AS HIGH PRESSURE WAS OVER THE FLORIDA STRAITS. THE COMBINATION OF THE TWO SYSTEMS WAS KEEPING THE WINDS OVER SOUTH FLORIDA EARLY THIS AFTERNOON MAINLY OUT OF THE SOUTH TO SOUTHWEST DIRECTION. THE EAST COAST SEA BREEZE WAS TRYING TO FORM OVER THE MIAMI-DADE AND BROWARD COUNTIES EARLY THIS AFTERNOON WHICH WAS HELPING TO GENERATE SHOWERS AND THUNDERSTORMS. SHOWERS AND THUNDERSTORMS WERE ALSO DEVELOPING EARLY THIS AFTERNOON OVER THE WEST COAST AND NORTHERN INTERIOR AREAS OF THE CWA ALONG THE WEST COAST SEA BREEZE AND THE STATIONARY FRONT. THE SHOWERS AND THUNDERSTORMS SHOULD BECOME MORE NUMEROUS OVER SOUTH FLORIDA THIS AFTERNOON...DUE TO THE HEATING OF THE DAY AND THE OUTFLOW BOUNDARIES. A FEW STRONG COULD BECOME STRONG LATE THIS AFTERNOON OR EARLY EVENING OVER THE EAST COAST METRO REGIONS WITH GUSTY WINDS AND HEAVY RAINFALL ESPECIALLY WHERE THE OUTFLOWS FROM EARLY THUNDERSTORMS COLLIDE WITH THE EAST COAST SEA BREEZE. THERE COULD ALSO BE SOME LOCALIZE FLOODING DUE TO THE LOW VALUES TO NECESSARY TO PRODUCE FLOODING OVER THE CWA. THE SHOWERS AND THUNDERSTORMS ACTIVITY SHOULD THEN DISSIPATE THIS EVENING OVER MUCH OF THE CWA AS THE HEATING OF THE DAY IS LOST...BUT THERE COULD STILL BE A FEW SHOWERS OR THUNDERSTORMS THAT AFFECT THE WEST METRO COAST AND SOUTHEAST METRO COAST OF THE CWA THROUGH THE OVERNIGHT HOURS. THERE WAS ALSO SOME PATCHY FOG OVER INTERIOR AND THE WESTERN EAST COAST METRO AREAS OF SOUTH FLORIDA THIS MORNING. THE PATCHY FOG COULD REDEVELOP AGAIN IN THE SAME AREAS OF THE CWA TONIGHT...DUE TO THE LIGHT SOUTHWEST STEERING FLOW...THE FRONT NEARBY...AND THE SHOWERS AND THUNDERSTORMS ACTIVITY THIS AFTERNOON. SO PLAN ON MENTIONING PATCHY FOG OVER THE INTERIOR AND WESTERN EAST COAST METRO AREAS OF SOUTH FLORIDA IN THE AFTERNOON ZONE PACKAGE. THE STATIONARY FRONT WILL THEN START TO MOVE NORTH ON MONDAY INTO NORTH FLORIDA...AS THE DISTURBED WEATHER OVER THE WESTERN CARIBBEAN SEA MOVES WEST NORTHWEST INTO THE SOUTH CENTRAL GULF OF MEXICO. THIS WILL ALLOW FOR HIGH PRESSURE TO BUILD FROM THE BAHAMAS INTO SOUTH FLORIDA AND BRING IN DRIER AIR. THERE COULD BE SOME SHOWERS AND THUNDERSTORMS ON MONDAY...BUT MOST OF THEM SHOULD OCCUR OVER THE INTERIOR AND NORTHERN PORTIONS OF THE CWA. THE HIGH WILL THEN DRIFT A LITTLE SOUTH ON TUESDAY TO THE KEYS...AND THIS WILL ALLOW FOR THE SHOWERS AND THUNDERSTORMS ACTIVITY TO SHIFT BACK TO THE EAST COAST METRO AREAS OF SOUTH FLORIDA. .EXTENDED FORECAST...THE HIGH WILL THEN SHIFT BACK NORTH OVER SOUTH FLORIDA MIDDLE TO LATE NEXT WEEK BEFORE MOVING BACK TO THE KEYS NEXT WEEKEND...AS A TROUGH OF LOW PRESSURE DEVELOPS OVER THE EASTERN US. A TROPICAL WAVE EAST OF THE WINDWARD ISLAND WILL ALSO MOVE WEST NORTHWEST AND COULD MOVE INTO SOUTH FLORIDA FOR NEXT WEEKEND INCREASING THE TROPICAL MOISTURE AND THE SHOWERS AND THUNDERSTORMS FOR SOUTH FLORIDA. && .MARINE...WINDS WILL REMAIN MOSTLY SOUTH OVER THE CWA WATERS THROUGH THE WEEK WITH WIND SPEEDS OF 10 KNOTS OR LESS. THE SEAS WILL REMAIN BELOW 2 FEET OR LESS. && .FIRE WEATHER...NO CONCERNS. && .PRELIMINARY POINT TEMPS/POPS...
