AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MELBOURNE FL 255 PM EDT MON JUN 21 2004 .DISCUSSION... NWS DOPPLER RADAR IS PICKING UP THE EAST COAST SEA BREEZE BOUNDARY AS IT BEGINS TO PUSH INLAND...AND SFC OBSERVATIONS CONFIRM THIS. NEXRAD HAS ALSO BEEN PICKING UP A FEW FIRES (LIKELY CONTROLLED BURNS) ALONG THE KISSIMMEE RIVER IN OSCEOLA AND POLK COUNTIES THIS AFTERNOON. 15Z CAPE SOUNDING SHOWS PCP WATER IS HOLDING AT 1.9... SLIGHTLY LOWER THAN YESTERDAY BUT STILL PLENTY MOIST. DEEPEST MOISTURE IS POOLED ACROSS NORTH FLORIDA ASSOCD WITH OLD FRONTAL BOUNDARY AND WIDESPREAD STRONG CONVECTION HAS ALREADY BROKEN OUT JUST NORTH OF OUR FA. EXPECT COVERAGE AND INTENSITY OF STORMS TO INCREASE NEXT FEW HOURS IN EC FL AS EAST COAST BREEZE PUSHES SLOWLY INLAND AND INTERACTS WITH STORM OUTFLOWS APPROACHING FROM THE SW AND PROPOGATING SOUTH FROM NORTHERN CONVECTION. ULTIMATELY THERE WILL BE A COLLISION WITH THE WEST COAST BREEZE EARLY THIS EVENING...INLAND FROM THE COAST BUT EAST OF ORLANDO. AND IT IS HERE WE EXPECT THE STRONGEST STORMS OF THE DAY IN EC FL TO DEVELOP. SW FLOW WILL STEER ALL STORMS TOWARD THE NE AND ACROSS THE INTRACOASTAL AND ATLC WATERS. PRIMARY CONCERN REMAINS EXCESSIVE LIGHTNING STRIKES (12+ CG/MIN) WITH STRONG WIND GUSTS OF 40-50 MPH IN THE STRONGER CELLS. 60 MPH WINDS (SEVERE) ARE ALSO POSSIBLE BUT WILL BE ISOLATED. WARM TEMPS ALOFT (-6C AT H5 ACCORDING TO 11AM CAPE SOUNDING) DO NOT SUPPORT LARGE HAIL. TORRENTIAL RAIN ALSO WILL OCCUR WITH POTENTIAL FOR TEMPORARY ROAD FLOODING BUT STORM MOVEMENT IS A BIT FASTER TODAY. TUE...THE SEMI-PERMANENT ATLANTIC RIDGE WILL STRENGTHEN...WITH THE RIDGE AXIS REMAINING POSITIONED SOUTH OF THE FORECAST AREA. MEANWHILE...A FRONTAL BOUNDARY WILL MOVE OUT OF THE PLAINS AND INTO THE MID-MISSISSIPPI VALLEY. BETWEEN THESE SYSTEMS AND OVER THE FORECAST AREA...FLOW WILL INCREASE OUT OF THE SOUTHWEST TO AROUND 15-20 KT BETWEEN 2K AND 4K FT. THIS SHOULD BE STRONG ENOUGH TO PREVENT THE FORMATION OF THE SEA BREEZE ACROSS MUCH OF THE FORECAST AREA. THE ONLY EXCEPTION MAY BE ALONG THE IMMEDIATE TREASURE COAST...WHERE WINDS WILL BACK LATE IN THE AFTERNOON. INCREASING MOISTURE WILL ADVECT OUT OF THE SOUTHERN GOMEX REGION AND INTO THE CWA. WIDESPREAD CONVECTION WILL LIKELY DEVELOP AHEAD AND ALONG OF AN EASTWARD RACING WEST COAST SEA BREEZE. WITH BEST MOISTURE TO THE NORTH...WILL FOLLOW MAV POPS CLOSELY. RELATIVELY WARM TEMPERATURES ALOFT WILL CONTINUE TO RESULT IN THUNDERSTORMS WITH MAIN THREATS BEING HEAVY RAIN...FREQUENT LIGHTNING AND STRONG WIND GUSTS. WED-THU...THE MIDWEEK PERIOD LOOKS SLIGHTLY DRIER...CLOSER TO CLIMATOLOGICAL NORMS. DEEPEST MOISTURE AND STRONGEST CONVERGENCE WILL BE FOCUSED ACROSS THE NORTH...CLOSER TO THE STALLED FRONTAL BOUNDARY ACROSS THE SOUTHEAST. HOWEVER...SLIGHTLY COOLER CONDITIONS ALOFT MAY RESULT IN STRONGER STORMS. OFFSHORE FLOW WILL AGAIN TAKE CONVECTION TOWARDS THE EAST COAST LATE EACH AFTERNOON. FRI-MON...RIDGE AXIS WILL BEGIN A SLOW TRANSITION BACK TO THE NORTH. EXTREMELY WEAK FLOW WILL RESULT IN ACTIVE SEA BREEZE COLLISIONS ACROSS THE INTERIOR COUNTIES. SUFFICIENT MOISTURE WILL LEAD TO THE DEVELOPMENT OF STORMS...MAINLY ACROSS THE NORTHERN ZONES. FLOW WILL RETURN TO ONSHORE EARLY NEXT WEEK AS THE AXIS OF THE WESTERN ATLANTIC RIDGE MOVES NORTH OF THE CWA. && .MARINE...CONDITIONS WILL CHANGE VERY LITTLE THROUGH THE UPCOMING WEEK. WINDS AROUND 10 KT WILL GENERATE 1 TO 2 FT SEAS WILL LITTLE TO NO SWELL COMPONENT. MAIN HAZARDS WILL BE FREQUENT LIGHTNING AND LOCALLY STRONG WINDS AND ROUGH SEAS IN STORMS MOVING OFFSHORE. && .PRELIMINARY POINT TEMPS/POPS...

HAZARDOUS WEATHER OUTLOOK NATIONAL WEATHER SERVICE MELBOURNE FL 1130 AM EDT MON JUN 21 2004 AMZ550-555-570-575-FLZ041-044>047-053-054-058-059-064-141-144-147- 212100- BREVARD-INDIAN RIVER-LAKE-MARTIN-OKEECHOBEE-ORANGE-OSCEOLA-SEMINOLE- ST. LUCIE-VOLUSIA-FLAGLER BEACH TO JUPITER INLET OUT TO 60 NM- 1130 AM EDT MON JUN 21 2004 THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA. .DAY ONE...TODAY AND TONIGHT: ...THUNDERSTORM IMPACT... DEEP TROPICAL MOISTURE WILL REMAIN IN PLACE ACROSS EAST CENTRAL FLORIDA TODAY. SCATTERED SHOWERS AND LIGHTNING STORMS WILL DEVELOP ALONG THE LOCAL SEA AND LAKE BREEZE BOUNDARIES THROUGH THE MID AFTERNOON. DEEP LAYER SOUTHWEST FLOW OF MODERATE STRENGTH WILL AGAIN DELAY ONSET OF THE EAST COAST SEA BREEZE AND KEEP IT PINNED WITHIN ABOUT 10 MILES OF THE COAST THIS AFTERNOON. IT WILL ALSO ALLOW THE WEST COAST BREEZE TO MOVE QUICKLY ACROSS THE INTERIOR AND INTO THE THE EAST COAST COUNTIES BY LATE AFTERNOON AND EARLY EVENING. STORM COVERAGE IS EXPECTED TO BE HIGHEST NEAR THE COAST...ESPECIALLY FROM CAPE CANAVERAL NORTH TO ORMOND BEACH...FROM MID AFTERNOON INTO EARLY EVENING...WITH MUCH OF THE ACTIVITY PUSHING OFFSHORE INTO THE ATLANTIC BETWEEN 600 AND 900 PM. STORM MOTION WILL BE FASTER AND LESS ERRATIC THAN IT WAS DURING THE PAST SEVERAL DAYS...TOWARD THE NORTHEAST AT 15 TO 20 MPH. THE MAIN HAZARDS WILL BE FREQUENT TO EXCESSIVE LIGHTNING STRIKES AND STRONG GUSTY WINDS. THERE IS EVEN A THREAT FOR COIN SIZED HAIL AND AN ISOLATED TORNADO ALONG BOUNDARY COLLISIONS...ESPECIALLY NEAR THE EAST COAST. SEEK SHELTER IN AN ENCLOSED BUILDING OR AUTOMOBILE IF YOU ARE CAUGHT OUTSIDE AS A LIGHTNING STORM APPROACHES. PICNIC SHELTERS AND CONVERTIBLE AUTOMOBILES OFFER...NO PROTECTION...FROM THE DANGERS OF LIGHTNING. IF YOU FEEL YOUR SKIN TINGLE OR YOUR HAIR STAND ON END... LIGHTNING IS ABOUT TO STRIKE NEARBY SQUAT LOW TO THE GROUND ON THE BALLS OF YOUR FEET. PLACE YOUR HANDS ON YOUR KNEES WITH YOUR HEAD BETWEEN THEM. MAKE YOURSELF THE SMALLEST TARGET POSSIBLE...AND MINIMIZE YOUR CONTACT WITH THE GROUND. ...FLOOD IMPACT... THE THREAT FOR LOCALLY HEAVY RAINFALL AMOUNTS IS EXPECTED TO BE A LITTLE LOWER OVER THE INTERIOR...HOWEVER A COLLISION BETWEEN THE SEA BREEZES OVER THE COASTAL COUNTIES DURING THE LATE AFTERNOON OR EARLY EVENING COULD LEAD TO RAINFALL AMOUNTS UP TO AROUND THREE INCHES... WHICH WOULD CAUSE TEMPORARY INUNDATION OF SOME STREETS...CULVERTS... PARKING LOTS...INTERSECTIONS...AND OTHER LOW LYING AND POORLY DRAINED AREAS. ...MARINE THUNDERSTORM GUST IMPACT... SINCE THE SEA BREEZE WILL BE HELD NEAR THE COAST TODAY...THERE IS THE CHANCE FOR STRONG STORMS NEAR THE INTRACOASTAL AND NEAR SHORE ATLANTIC WATERS ALL AFTERNOON...WITH THE THREAT INCREASING DURING THE LATE AFTERNOON AND EARLY EVENING AS THE GULF BREEZE APPROACHES FROM THE WEST. ...WATERSPOUT IMPACT... THE COMBINATION OF MODERATE SOUTHWEST LOW LEVEL WINDS AND A LATE DAY SEA BREEZE CIRCULATION WILL CREATE A FAVORABLE LOW LEVEL SHEAR PROFILE CONDUCIVE FOR THE FORMATION OF WATERSPOUTS IN SOME OF THE STRONGER MARINE STORMS...ESPECIALLY OVER THE INTRACOASTAL AND NEAR SHORE ATLANTIC WATERS. .DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY: MOISTURE AND INSTABILITY LEVELS ACROSS FLORIDA WILL REMAIN HIGH ENOUGH TO ALLOW SCATTERED THUNDERSTORMS TO FORM EACH AFTERNOON. .SPOTTER INFORMATION STATEMENT... SPOTTERS ARE REQUESTED TO MONITOR THE WEATHER AND SELF ACTIVATE IF NEEDED. CRISTALDI/KELLY
