AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MELBOURNE FL 215 PM EDT THU JUL 9 2009 .DISCUSSION... REMAINDER OF THIS AFTERNOON...SHOWERS AND LIGHTNING STORMS WILL MOVE WEST TO EAST AT AROUND 15 TO 20 MPH ACROSS THE CENTER THIRD OF THE STATE. AN AREA OF STORMS OVER HIGHLANDS AND POLK COUNTIES WILL MOVE OVER OKEECHOBEE AND SOUTHERN OSCEOLA COUNTIES AND COUNTY AND INTO INDIAN RIVER...SAINT LUCIE AND MARTIN COUNTIES DURING THE AFTERNOON AND EARLY EVENING. COOLER TEMPERATURES ALOFT WILL STEEPEN MID LEVEL LAPSE RATES AND ENHANCE THE POTENTIAL FOR STRONG GUSTY WINDS (WET MICROBURSTS) AND HAIL ESPECIALLY ALONG THE COAST CAPE CANAVERAL SOUTH. SOME STORMS WILL BECOME STRONG TO POSSIBLY SEVERE AS THEY APPROACH THE COAST/MARINE ENVIRONMENT CAPE CANAVERAL TO JUPITER INLET. LOCATIONS ALONG THAT PORTION OF THE COASTLINE SHOULD KEEP AN EYE TO THE WEST FOR APPROACHING STORMS. FUNNEL CLOUDS AND WATER SPOUTS ARE NOT OUT OF THE QUESTION AS THE STRONGER STORMS MOVE OVER THE COASTAL AND ADJACENT NEARSHORE ATLANTIC WATERS. TONIGHT...STORMS SHOULD WIND DOWN BY SUNSET AS DAYTIME HEATING SUBSIDES AND ANY LINGERING STORMS/SHOWERS ENCOUNTER THE COOLING AIR FROM BOTH THE AREAS BEING WORKED OVER AND/OR LOSS OF DAYTIME HEATING. MID/HIGH LEVEL DEBRIS CLOUDINESS SHOULD DISSIPATE LATE OVERNIGHT. FRIDAY...DEEP SOUTHWEST FLOW WILL HAVE EMBEDDED SHOWERS IN IT AS IT MOVES FROM THE EASTERN GULF OF MEXICO AND ACROSS WEST AND EAST CENTRAL FLORIDA DURING THE MORNING. UPPER LEVEL TROUGH AXIS FORECAST TO MOVE OVER THE PENINSULA DURING THE DAY. COOLER AND DRIER MID LEVEL AIR MASS AND SOUTHWEST NORTHEAST MOVING VORTICITY MAXES MOVING OVER THE AREA SHOULD TRIGGER SCATTERED SHOWERS AND ISOLATED STORMS DURING THE MORNING. COVERAGE WILL INCREASE AS DAYTIME HEATING DESTABILIZES THE LOWER ATMOSPHERE AND THE ALREADY DESTABILIZED MID LEVELS WILL LEAD TO AT LEAST ISOLATED STRONG STORMS DURING THE AFTERNOON HOURS. SEA BREEZE FORMATION ALONG THE COAST CAPE CANAVERAL SOUTH WILL HAVE TO BE FACTORED IN FOR THE HAZARDOUS WEATHER PICTURE. (PREVIOUS DISCUSSION) SAT...DISTURBED/WET PATTERN WILL BEGIN TO TRANSITION TO MORE TYPICAL SUMMER THUNDERSTORM REGIME AS TROUGH ALOFT WEAKENS AND RIDGE LIFTS NORTH TOWARDS LAKE OKEECHOBEE. EXPECT ONE MORE DAY OF ABOVE NORMAL RAINFALL COVERAGE...WITH ACTIVE SEA BREEZE BOUNDARIES WORKING INLAND DURING THE AFTERNOON. STORMS EXPECTED TO MOVE INLAND OVER SOUTHERN THIRD OF CWA...BUT ENOUGH SW STEERING FLOW OVER NORTHERN CWA SHOULD KEEP CHANCE FOR STORMS NEAR COASTAL COUNTIES THROUGH THE DAY. SUN-WED...DEEP LAYER RIDGE LIFTS TO CENTRAL PENINSULA AND REMAINS GENERALLY STATIONARY THROUGH THE MIDDLE OF NEXT WEEK. MOISTURE DEPTH LOWERS TO SEASONABLE NORMS. NORMAL MID SUMMER PATTERN OF LIGHT WINDS AND ACTIVE/INLAND MOVING SEA BREEZE BOUNDARIES SUGGESTS A 34-40 PERCENT COVERAGE OF STORMS EACH AFTERNOON. RAIN CHANCES WILL BE GREATEST MID DAY TO EARLY AFTERNOON ACROSS THE COASTAL COUNTIES...THEN TRANSITIONING TO THE INTERIOR COUNTIES BY MID-LATE AFTERNOON. TEMPS NEAR NORMAL. && .AVIATION...SCT/NMRS TSRA THROUGH SUNSET WITH MVFR TEMPO IFR CONDITIONS AND THE POTENTIAL FOR SFC WND G40-50KT AND COIN SIZE HAIL WITH STRONGER STORMS. ACTIVITY DIMINISHING AND MOST AREAS BECOMING VFR AGAIN BTWN 1002Z AND 1004Z. ISOLATED MVFR SHOWERS AND LATE MORNING STORMS 10/13Z-10/18Z. && .MARINE...NDBC AND SCRIPPS BUOYS RECORDING LONG PERIOD 1 TO 2 FOOT SEAS AND SOUTHWEST WINDS AROUND 10 KNOTS. AFTERNOON SEA BREEZES CAPE CANAVERAL SOUTH WILL ENHANCE STRONG LIGHTNING STORM POTENTIAL AS THE STORMS MOVE OFF THE MAINLAND...CROSSING THE INTRACOASTAL WATERWAY (ICW) AND ENTER THE NEARSHORE WATERS CANAVERAL SOUTH. WEATHER WINDS DOWN BY MIDNIGHT WITH PREVAILING SOUTHWEST FLOW TAKING OVER AGAIN. FRI...SOUTHWEST WINDS AROUND 10 KNOTS WITH AFTERNOON SEA BREEZE FORMING AND INCREASING THE POTENTIAL FOR MORE STRONG STORMS MOVING OFF THE MAINLAND AND INTO THE ICW AND NEARSHORE WATERS MID TO LATE AFTERNOON. SAT-TUE...NO GRADIENT WIND/SEA CONCERNS. SAT AFTERNOON...STORMS SHOULD PUSH INLAND SOUTH OF MLB...BUT MAY LINGER OR PUSH OFFSHORE FARTHER NORTH DURING THE AFTERNOON/EARLY EVENING. SUN-TUE...NORTHERN MOVING RIDGE AXIS WILL SHIFT STORM PATTERN MAINLY INLAND DURING THE AFTERNOONS. && .PRELIMINARY POINT TEMPS/POPS...

LUCIE-MARTIN-COASTAL VOLUSIA- SOUTHERN LAKE-NORTHERN BREVARD- 1106 AM EDT THU JUL 9 2009 THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA. .DAY ONE...THIS AFTERNOON AND TONIGHT. ...THUNDERSTORM IMPACT... AN UPPER LEVEL DISTURBANCE...COOLING TEMPERATURES ALOFT AND DEVELOPMENT OF THE EAST COAST SEA BREEZE FROM AROUND CAPE CANAVERAL SOUTHWARD WILL ALLOW NUMEROUS STORMS TO DEVELOP TODAY WITH THE POTENTIAL FOR A FEW SEVERE THUNDERSTORMS. ANY STORMS TODAY WILL BE CAPABLE OF PRODUCING VERY HEAVY DOWNPOURS... STRONG WIND GUSTS OF 40 MPH...FREQUENT CLOUD TO GROUND LIGHTNING... AND SMALL HAIL. A FEW OF THE STORMS MAY BECOME SEVERE...ESPECIALLY NEAR THE COAST AS THE EAST COAST SEA BREEZE DEVELOPS WITH THE MAIN CONCENTRATION ALONG THE COAST CAPE CANAVERAL SOUTH WHERE THE SEA BREEZE SHOULD FORM MID TO LATE AFTERNOON. THESE STORMS MAY PRODUCE DAMAGING WIND GUSTS...COIN SIZE HAIL AND POSSIBLY A ROTATING STORM OR WATERSPOUT AS THEY NEAR THE EAST COAST. THERE WERE TWO AREAS WITH LIGHTNING VICTIMS IN EAST CENTRAL FLORIDA ON WEDNESDAY. OFTEN THESE DANGEROUS STRIKES OCCUR WELL BEFORE OR AFTER THE HEAVY RAIN IS OVER YOUR LOCATION. MOVE INDOORS WELL IN ADVANCE OF AN APPROACHING STORM AND REMAIN INSIDE UNTIL 30 MINUTES AFTER THE LAST THUNDER IS HEARD. ...RIP CURRENT IMPACT... A LONG PERIOD EASTERLY SWELL AND HIGH ASTRONOMICAL TIDES WILL CONTRIBUTE TO AN ELEVATED RIP CURRENT RISK AT THE BEACHES. ALWAYS SWIM WITHIN SIGHT OF A LIFE GUARD AND NEVER SWIM ALONE. ...MARINE THUNDERSTORM GUST IMPACT... EASTWARD MOVING STORMS WILL AFFECT THE INLAND LAKES MAINLY FROM SOUTH BREVARD TO MARTIN COUNTY. THE SEA BREEZE FORMATION NEAR THE EAST COAST WILL HELP STRENGTHEN STORMS OVER THE INTRACOASTAL AND NEAR SHORE ATLANTIC WATERS. STRONG GUSTY WINDS...CLOUD TO WATER LIGHTNING...A FEW WATERSPOUTS AND HEAVY RAIN CAN BE EXPECTED FROM CAPE CANAVERAL TO JUPITER INLET. BOATERS SHOULD SEEK SAFE HARBOR WELL BEFORE STORMS APPROACH FROM THE WEST. ...WATERSPOUT IMPACT... A FEW WATERSPOUTS WILL BE POSSIBLE NEAR THE COAST AS STORMS MOVE OVER THE COASTAL AREAS AND NEARSHORE WATERS FROM CAPE CANAVERAL TO JUPITER INLET. .DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY. HIGHER THUNDERSTORM CHANCES AND POTENTIAL FOR A FEW SEVERE STORMS CAN BE EXPECTED AGAIN ON FRIDAY. THE SURFACE RIDGE WILL BEGIN TO SHIFT NORTHWARD OVER CENTRAL FLORIDA THIS WEEKEND WITH A GRADUAL TREND BACK TOWARD SCATTERED COVERAGE OF SEA BREEZE BOUNDARY GENERATED LIGHTNING STORMS EACH AFTERNOON. .SPOTTER INFORMATION STATEMENT... SPOTTERS ARE REQUESTED TO MONITOR THE WEATHER AND SELF ACTIVATE IF NEEDED. GLITTO/UPDATE WIMMER
