AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MELBOURNE FL 255 PM EDT SAT SEP 24 2011 .DISCUSSION... CURRENT-TONIGHT...WITH LACK OF SIGNIFICANT MID AND UPPER LEVEL FORCING MOST/ALL OF THE CONVECTION SHOULD BE MESOSCALE DRIVEN...SEA BREEZE COLLISIONS AND OUTFLOW BOUNDARIES INTERACTING WITH EACH OTHER THE REST OF THE AFTERNOON AND THROUGH LATE EVENING BEFORE WINDING DOWN. VERY MOIST ATMOSPHERE...PRECIPITABLE WATER VALUES AROUND 2 INCHES... AND LIGHT SOUTHWEST FLOW ABOVE THE SURFACE WILL PRODUCE SLOW MOVING STORMS CAPABLE OF LOCALLY HEAVY RAIN. BOUNDARY INTERACTION SHOULD YIELD FREQUENT LIGHTNING STRIKES FROM THE STRONGER STORMS. AFTERNOON CONVECTION EXPECTED TO LAST THROUGH THE EVENING BEFORE DISSIPATING. LOW AND MID LEVEL DEBRIS CLOUD SHOULD DISSIPATE AROUND MIDNIGHT WITH CLEARING SKIES THROUGH SUNRISE. WINDS SHOULD DIMINISH TO LIGHT OR CALM AS THE ATMOSPHERE DECOUPLES TOWARD SUNRISE. LOW CLOUDS MAY FORM AGAIN OVER AREAS THAT RECEIVED RAIN IF THE SOUTH TO SOUTHWEST WINDS ABOVE THE INVERSION ARE STRONG ENOUGH. SUN-SUN NIGHT...SOUTHERLY FLOW BETWEEN THE DEEP UPPER LEVEL CUTOFF LOW OVER THE MIDWEST AND THE STRONG UPPER HIGH OVER BERMUDA WILL CONTINUE TO PULL MOISTURE UP THE PENINSULA. AT THE SURFACE...AN INVERTED TROUGH UNDER THE UPPER LEVEL SOUTHERLY FLOW WILL PERSIST THROUGH THE DAY. THIS WILL CONTINUE TO PRODUCE A LIGHT WIND FIELD OVER THE PENINSULA. THE LIGHT SURFACE WIND PROFILE WILL ALLOW SEA BREEZES TO FORM BY EARLY AFTERNOON. HOWEVER...THE EAST COAST SEA BREEZE SHOULD MOVE INLAND SLOWER DUE TO THE INITIAL SOUTH TO SOUTHWEST SURFACE FLOW. THIS WILL RESULT IN STORMS MOVING TO THE NORTH AND NORTHEAST BACK TOWARD THE EAST COAST. WEAK IMPULSES MOVING OVERHEAD IN THE MID LEVEL SOUTHWEST FLOW AND BOUNDARY COLLISIONS WILL RESULT IN ANOTHER 50 TO 60 POP FOR SUNDAY AFTERNOON WITH STORMS OVER THE INTERIOR LINGERING INTO THE EVENING BEFORE ENDING BY MIDNIGHT. PREVIOUS LONG TERM DISCUSSION... MON-FRI...LARGE CUT OFF LOW WILL CONTINUE TO MEANDER OVER THE UPPER MIDWEST INTO MID NEXT WEEK...SLOWLY SHIFTING INTO NEW ENGLAND BY LATE WEEK. BOTH THE GFS AND ECMWF ARE STILL POINTING TO A DRIER PATTERN FOR MID WEEK AS THE UPPER LEVEL LOW LIFTS OUT INTO NEW ENGLAND AND THE ASSOCIATED TROUGH AXIS PUSHES THE DEEP MOISTURE OVER THE STATE FURTHER SOUTH AND EAST. POPS WILL BE BELOW NORMAL AT 20-30 PERCENT TUES-THURS WITH THE BEST RAIN CHANCES ACROSS THE TREASURE COAST AND NEAR LAKE OKEECHOBEE. THE ECMWF AND GFS SOLUTIONS DIVERGE AS WE GO INTO LATE NEXT WEEK AS TO HOW MUCH AND HOW QUICKLY MOISTURE RETURNS ACROSS THE PENINSULA. NOT MUCH CHANGE IN TEMPERATURES THROUGH THE PERIOD WITH UPPER 80S AND LOW 90S FOR HIGHS. LOW TEMPS WILL DROP FROM THE MID 70S EARLY IN THE WEEK TO UPPER 60S/LOW 70S BY MID-LATE WEEK AS DRIER AIR FILTERS IN. && .AVIATION... BACKED OFF A COUPLE OF HOURS...19Z-20Z...BEFORE STARTING AFTERNOON STORMS BUT KEPT VCTS THROUGH 00Z. SHOULD BE LIKE LAST NIGHT WITH STORMS LINGERING THROUGH MIDNIGHT/04Z. DEBRIS CLOUDS WILL DISSIPATE AFTER 2AM/06Z WITH SOME DECOUPLING OF THE LOWEST LAYERS TOWARD SUNRISE...AROUND 6AM/10Z. SOUTH TO SOUTHWEST WIND JUST ABOVE THE SURFACE LAYER MAYBE STRONG ENOUGH FOR LIFR-IFR STRATUS 10Z-13Z BEFORE LIFTING. LIGHT SOUTH TO SOUTHWEST WINDS THROUGH LATE MORNING THEN DEVELOPING SEA BREEZES WILL SHIFT WINDS TO THE EAST AND SOUTHEAST 2PM-4PM/18Z- 20Z. MARINE... SUN-WED...WEAK PRESSURE GRADIENT OVER THE REGION WILL KEEP THE FLOW RELATIVELY LIGHT INTO EARLY NEXT WEEK. SOUTH-SOUTHWESTERLY WINDS EXPECTED DURING THE NIGHTS AND MORNINGS WITH FLOW BECOMING SOUTHEAST NEAR THE COAST WITH THE DAILY SEA BREEZE. WIND SPEEDS GENERALLY AROUND 10 KTS...10-15KITS WITH THE DEVELOPMENT OF THE SEA BREEZE EACH AFTERNOON. A DISSIPATING BOUNDARY MOVING OVER THE AREA WILL PRODUCE LIGHT WINDS TUE NIGHT AND EARLY WED. WINDS START A SHIFT BACK TO THE SOUTH AND EAST LATE WED AS HIGH PRESSURE BEGINS REBUILDING EAST TO WEST ACROSS THE COASTAL WATERS AND CENTRAL FLORIDA.WEAK BOUNDARY PASSING THROUGH THE REGION TUE NIGHT IS EXPECTED TO VEER WINDS AROUND TO THE NORTHEAST BY THE AFTERNOON IN ITS WAKE...BUT MODELS DIFFER SLIGHTLY ON HOW QUICKLY THIS BOUNDARY PASSES. SEAS WILL BE AT 2-4FT NEARSHORE AND 3-5FT OFFSHORE...BECOMING 5-6FT OFFSHORE MON AND TUES AS A SWELL TRAIN FROM THE ATLANTIC BRIEFLY MOVES THROUGH. STEERING FLOW FOR STORMS EACH AFTN AND EVENING WILL BE OFFSHORE AT AROUND 10 KNOTS AHEAD OF AN APPROACHING FRONTAL SYSTEM/UPPER TROUGH. COVERAGE OF SHOWERS AND STORMS WILL DIMINISH AFTER MONDAY WITH THE PASSAGE OF THE TROUGH. && .PRELIMINARY POINT TEMPS/POPS...

LUCIE-MARTIN-COASTAL VOLUSIA- SOUTHERN LAKE-NORTHERN BREVARD- 1030 AM EDT SAT SEP 24 2011 THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA. .DAY ONE...THIS AFTERNOON AND TONIGHT. .THUNDERSTORM IMPACT... DEEP MOISTURE ALONG WITH SURFACE HEATING AND BOUNDARY COLLISIONS WILL SUPPORT SCATTERED TO NUMEROUS LIGHTNING STORMS THIS AFTERNOON. THE EAST COAST SEA SEA BREEZE WILL DEVELOP EARLY AFTERNOON WITH A FEW STORMS FORMING ALONG IT AS IT PUSHES INLAND. INCREASED STORM COVERAGE AND INTENSITY IS EXPECTED LATE THIS AFTERNOON OVER INTERIOR COUNTIES AS BOUNDARIES AND STORM OUTFLOWS INTERACT. STORMS WILL DRIFT SLOWLY TO THE EAST-NORTHEAST BACK TOWARD THE EAST COAST. FREQUENT CLOUD TO GROUND LIGHTNING WILL BE THE MAIN THREAT. A FEW STRONGER STORMS MAY PRODUCE WIND GUSTS UP TO 45 MPH. ALSO...NUMEROUS BOUNDARY INTERACTIONS MAY PRODUCE A BRIEF FUNNEL CLOUD OR LANDSPOUT. .FLOOD IMPACT... DEEP MOISTURE AND SLOW STORM MOTION WILL ALLOW STORMS TO PRODUCE LOCALLY HEAVY RAINS. AREAS WHERE MORE THAN ONE STORM MOVES THROUGH WILL BE CAPABLE OF PRODUCING UP TO 4 INCHES OF RAIN IN A FEW SPOTS. THE BEST CHANCE FOR SEEING SUCH POCKETS OF EXCESSIVE RAINFALL WILL BE OVER INTERIOR COUNTIES DURING THE LATE AFTERNOON. THIS WOULD PRODUCE AT LEAST NUISANCE FLOODING OF LOW LYING AND POOR DRAINAGE AREAS WITH MORE SIGNIFICANT IMPACTS POSSIBLE OVER AN URBANIZED AREA. .RIP CURRENT IMPACT... WEATHER AND OCEAN CONDITIONS WILL PRODUCE A MODERATE THREAT FOR RIP CURRENTS AT THE BEACHES OF EAST CENTRAL FLORIDA TODAY. ALWAYS SWIM WITHIN SIGHT OF A LIFEGUARD. .MARINE THUNDERSTORM GUST IMPACT... STORMS WILL BE CAPABLE OF PRODUCING STRONG WIND GUSTS AROUND 35 KNOTS OVER INLAND LAKES THIS AFTERNOON. SOME OF THE STORMS ARE FORECAST TO REACH THE EAST COAST EARLY TONIGHT AND MAY ALSO PRODUCE STRONG GUSTY WINDS. STORMS WILL MOVE SLOWLY TO THE EAST-NORTHEAST. .DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY. DEEP MOISTURE WILL REMAIN IN PLACE SUNDAY AND MONDAY WHICH WILL SUPPORT SCATTERED LIGHTNING STORMS CAPABLE OF PRODUCING FREQUENT LIGHTNING AND HEAVY RAINS. AT THE SAME TIME THERE WILL BE AN INCREASING THREAT FOR OFFSHORE MOVING STORMS. DRIER AIR IS FORECAST TO MOVE INTO EAST CENTRAL FLORIDA NEXT WEEK AND REDUCE RAIN CHANCES. .SPOTTER INFORMATION STATEMENT... SPOTTERS ARE REQUESTED TO MONITOR THE WEATHER AND SELF ACTIVATE IF NEEDED. PLEASE REPORT TO THE NATIONAL WEATHER SERVICE RAINFALL AMOUNTS OF 2 INCHES OR GREATER IN ONE HOUR...OR TOTAL ACCUMULATIONS OF 3 INCHES OR GREATER. KELLY/GLITTO
