SOUTH FLORIDA FORECAST DISCUSSION. NATIONAL WEATHER SERVICE MIAMI FL 145 PM EDT FRI AUG 6 2004 .DISCUSSION...A TROUGH OF LOW PRESSURE IN THE UPPER LEVELS OF THE ATMOSPHERE EXTENDED FROM THE GREAT LAKES SOUTHWARD TO JUST EAST OF FLORIDA THIS MORNING...WHILE HIGH PRESSURE ALOFT WAS LOCATED OVER THE LONE STAR STATE. THE COMBINATION OF THESE TWO SYSTEMS WAS CAUSING THE STEERING FLOW OVER THE CWA TO BE NORTHWEST EARLY THIS AFTERNOON...AND DRIVE THE SHOWERS AND THUNDERSTORMS SOUTHEAST ACROSS THE CWA. THE SHOWERS AND THUNDERSTORMS SHOULD CONTINUE TO DEVELOP OVER SOUTH FLORIDA THROUGH THE AFTERNOON HOURS...AS THE PWAT WAS 2.08 INCHES FROM THE MIA SOUNDING THIS MORNING. THERE COULD EVEN BE A FEW STRONG STORMS OVER THE EAST COAST METRO AREAS OF THE CWA LATE THIS AFTERNOON OR EARLY EVENING...SOME DRIER AIR ON SATELLITE OVER NORTH AND CENTRAL FLORIDA HAS WORKED INTO SOUTH FLORIDA EARLY THIS AFTERNOON. SO PLAN ON MENTIONING A FEW STORM COULD BECOME STRONG WITH GUSTY WINDS AND SMALL HAIL FOR THIS EVENING. THE COLD FRONT OVER NORTH FLORIDA WILL SLOWLY MOVE SOUTH INTO CENTRAL FLORIDA TONIGHT...AS THE TROPICAL WAVE OVER THE CENTRAL BAHAMAS WILL MOVE WEST INTO WESTERN CARIBBEAN SEA WITH THE NORTHERN PORTION OF THIS WAVE MOVING THROUGH THE FLORIDA STRAITS. SO PLAN ON LEAVING ISOLATED SHOWERS AND THUNDERSTORMS IN FOR MOST OF THE CWA FOR THE OVERNIGHT HOURS...DUE TO THE COMBINATION OF THE FRONT AND THE TROPICAL WAVE. FOR THE WEST COAST METRO REGIONS PLAN ON LEAVING SCATTERED ACTIVITY OVERNIGHT...AS THERE SHOULD BE SCATTERED SHOWERS AND THUNDERSTORMS ACTIVITY IN THE GULF THAT WILL MOVE INTO THE WESTERN AREAS OF THE CWA. THE TROPICAL WAVE OVER THE WESTERN CARIBBEAN SEA WILL MOVE INTO THE SOUTHERN GULF OF MEXICO THIS WEEKEND...AS THE COLD FRONT WILL REMAIN NEARLY STATIONARY OVER CENTRAL FLORIDA ON SATURDAY BEFORE MOVING SLOWLY NORTHWARD ON SUNDAY. SO PLAN ON LEAVING NUMEROUS ACTIVITY OVER MOST OF THE CWA FOR SATURDAY...THEN NUMEROUS OVER THE NORTHERN PORTION OF THE CWA TO SCATTERED OVER THE SOUTHERN PORTIONS OF THE CWA ON SUNDAY. .EXTENDED FORECAST...THE COLD FRONT WILL GET PUSH INTO THE SOUTHEAST US EARLY NEXT WEEK...AS HIGH PRESSURE ALOFT BUILDS INTO SOUTH FLORIDA FROM THE FLORIDA STRAITS. THIS WILL ALLOW THE WINDS TO BECOME SOUTH TO SOUTHEAST EARLY NEXT WEEK OF SOUTH FLORIDA...AND PUSH THE SHOWERS AND THUNDERSTORMS ACTIVITY TO THE NORTHERN PORTIONS OF THE CWA. THE HIGH PRESSURE ALOFT WILL THEN GET PUSH SOUTH AGAIN LATE NEXT WEEK...AS ANOTHER TROUGH OF LOW PRESSURE DEVELOPS OVER THE EASTERN US. SO SOUTH FLORIDA WILL GET BACK INTO A SOUTHWEST FLOW WITH A GOOD CHANCE OF SHOWERS AND THUNDERSTORMS ACTIVITY LATE NEXT WEEK. && .MARINE...WINDS WILL REMAIN WEST/SOUTHWEST THROUGH SATURDAY AT 5 TO 10 KNOTS BEFORE SWINGING BACK TO THE S/SE LATE IN THE WEEKEND INTO EARLY NEXT WEEK...AS A RIDGE OF HIGH PRESSURE BUILDS INTO SOUTH FLORIDA. SO THE BOATING WEATHER SHOULD BE GOOD THIS WEEKEND...EXPECT FOR THE DODGING OF THE SHOWERS AND THUNDERSTORMS. && .FIRE WEATHER...NO CONCERNS AS THE RELATIVE HUMIDITIES WILL REMAIN HIGH AND WINDS LIGHT. && .PRELIMINARY POINT TEMPS/POPS...
