The east coast sea breeze as well as outflow boundaries from other storms collided with a southwest to northeast oriented boundary over northern portions of East Central Florida. The result was a number of clusters of storms which produced sub-severe hail.

NWS Melbourne, FL wrote its last area forecast discussion before the first event at Jul 9, 2:03 PM EST, 1 hour earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MELBOURNE FL 303 PM EDT MON JUL 9 2012 .DISCUSSION... TONIGHT...COVERAGE OF EAST COAST SEA BREEZE STORMS HAS BEEN GREATER THAN PREVIOUS DAYS DUE TO A LITTLE MORE MOISTURE AND COOLER TEMPS ALOFT. ACTIVITY ALSO BROKE OUT IN ZONE OF WEAK LOW LEVEL CONVERGENCE INLAND TO LAKE COUNTY. WILL CARRY A CHANCE FOR STORMS OVER THE NORTH INTERIOR AND A SLIGHT CHANCE FOR STORMS OVER THE INTERIOR SOUTH UNTIL ABOUT SUNSET. INCREASING MOISTURE FROM THE SOUTHEAST SHOULD BRING A SLIGHT CHANCE FOR SHOWERS TO THE TREASURE COAST DURING THE OVERNIGHT. TUE-WED...A LOW-MID LEVEL RIDGE WILL BECOME ESTABLISHED OVER THE ATLANTIC WHICH WILL LEAD TO A DEEPER LAYER OF SOUTHEAST WINDS. THIS WILL INCREASE MOISTURE AS THE MODELS HAVE BEEN SHOWING FOR THE PAST SEVERAL DAYS. HAVE NOT MADE MUCH CHANGE TO THE PREVIOUS FORECAST...WHICH RETURNS SCATTERED POPS TO ALL OF THE AREA. WITH THE HIGHER MOISTURE AMOUNTS...THE MAIN THREATS FROM STORMS SHOULD TRANSITION TO FREQUENT-EXCESSIVE LIGHTNING AND PONDING WATER FROM 2-3 INCH DOWNPOURS. HIGH TEMPS MAY STILL NUDGE INTO THE MID 90S ACROSS THE NORTH INTERIOR BUT WITH MORE SHOWERS/STORMS AROUND...THERE WILL BE SOME RELIEF BY MID-LATE AFTERNOON. THU-WEEKEND...(PREVIOUS DISCUSSION) RIDGE AXIS CONTINUES TO BUILD NORTHWARD FROM LATE WEEK INTO THE WEEKEND WITH LOW LEVEL E/SE FLOW MAINTAINING A MOIST INFLOW...KEEPING RAIN CHANCES GENERALLY AROUND CLIMO (40-50%). TEMPS CHANGE LITTLE WITH VALUES NEAR TO SLIGHTLY ABOVE NORMAL. && .AVIATION... AFTERNOON SHOWERS/STORMS ARE STILL SCATTERED BUT A FEW COULD IMPACT TERMINALS AND REQUIRE A SHORT TEMPO GROUP OVER THE INTERIOR. OVERNIGHT WE ARE EXPECTING VFR. A SMALL CHANCE FOR MVFR SHOWERS EXISTS ALONG THE SOUTHEAST COAST...KSUA TO ABOUT KFPR. HIGHER MOISTURE ON TUE SHOULD BRING AN EARLIER START TO SHRA/TSRA CHANCES...PARTICULARLY KSUA-KMLB WHICH COULD HAVE VICINITY ACTIVITY IN THE MORNING HOURS. THIS EARLIER CONVECTION WILL HAVE A NORTHWEST TO NORTH MOVEMENT/PROPAGATION UP THE PENINSULA AND THE INTERIOR TERMINALS COULD REQUIRE TEMPO GROUPS TOWARDS 16Z-17Z. && .MARINE... TONIGHT-TUE...AXIS OF ATLANTIC RIDGE WILL EXTEND ACROSS THE AREA WITH CONTINUED SOUTHEAST/SOUTH FLOW AROUND 10 KNOTS. AN INCREASE TO 10-15 KNOTS IS POSSIBLE IN THE NORTH DURING THE EVENING/OVERNIGHT. MARINERS CAN ALSO EXPECT SCATTERED SHOWERS AND ISOLATED STORMS TO OCCUR IN THE SOUTHERN WATERS AND SLOWLY WORK FARTHER NORTH ON TUE. WED-SAT...THE AXIS OF THE ATLANTIC RIDGE IS SHOWN SHIFTING NORTH OF THE WATERS. THIS WILL BRING A SOUTHEAST TO EAST WIND FLOW WITH THE LATEST MODEL RUN SHOWING SPEEDS BUMPING UP A LITTLE...TO 10-15 KNOTS. THE GFS SHOWS BANDS OF MOISTURE MOVING THROUGH SO EXPECT A FEW PERIODS WITH SCATTERED SHOWERS AND ISOLATED STORMS. && .PRELIMINARY POINT TEMPS/POPS...

LUCIE-MARTIN-COASTAL VOLUSIA- SOUTHERN LAKE-NORTHERN BREVARD- 1210 PM EDT MON JUL 9 2012 THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA. .DAY ONE...THIS AFTERNOON AND TONIGHT. .THUNDERSTORM IMPACT... A SLIGHT INCREASE IN MOISTURE ACROSS THE REGION TODAY WILL ALLOW ISOLATED SHOWERS AND LIGHTNING STORMS TO DEVELOP ALONG THE EAST COAST SEA BREEZE EARLY THIS AFTERNOON. ACTIVITY IS EXPECTED TO DEVELOP JUST INLAND FROM THE COAST ACROSS VOLUSIA COUNTY AND THE TREASURE COAST. COVERAGE WILL INCREASE OVER THE INTERIOR SECTIONS LATE THIS AFTERNOON AS THE SEA BREEZE PUSHES INLAND AND COLLIDES WITH THE WEST COAST SEA BREEZE AND ANY LOCAL LAKE AND OUTFLOW BOUNDARIES. THE HIGHEST COVERAGE IS EXPECTED TO BE ALONG AND NORTH OF THE I-4 CORRIDOR IN THE LATE AFTERNOON. CONDITIONS ARE FAVORABLE FOR SUCH STORMS TO PRODUCE STRONG DOWNBURST WINDS...HAIL AND FREQUENT CLOUD TO GROUND LIGHTNING. DAMAGING WINDS NEAR 60 MPH AND LARGE HAIL WILL BE POSSIBLE IN ONE OR TWO OF THESE STORMS LATE THIS AFTERNOON. STORM MOTION WILL REMAIN SLOW AND ERRATIC. .FLOOD IMPACT... STORM MOTION WILL REMAIN WEAK THIS AFTERNOON...ALLOWING ANY ORGANIZED STORMS TO PRODUCE UP TO 3 INCHES OF RAIN IN A COUPLE HOURS OVER PORTIONS OF THE NORTH INTERIOR...INCLUDING INTERIOR VOLUSIA...LAKE...SEMINOLE AND ORANGE COUNTIES. SUCH HEAVY RAINFALL WOULD CAUSE TEMPORARY FLOODING OF SOME ROADS AND POOR DRAINAGE AREAS...BUT IMPACTS WOULD REMAIN VERY LOCALIZED. .MARINE THUNDERSTORM GUST IMPACT... A FEW LIGHTNING STORMS MAY AFFECT THE INTRACOASTAL WATERS ACROSS VOLUSIA COUNTY AND THE TREASURE COAST EARLY THIS AFTERNOON...BUT HIGHER COVERAGE IS EXPECTED OVER THE INTERIOR LATE THIS AFTERNOON. THIS WOULD INCLUDE SOME OF THE LARGER INLAND LAKES SUCH AS LAKE GEORGE...LAKE APOPKA AND AROUND LAKE OKEECHOBEE. STORMS WILL BE SLOW MOVING AND ONE OR TWO WILL BE CAPABLE OF PRODUCING STRONG DOWNBURST WINDS OF 35 TO 45 KNOTS... HAIL AND FREQUENT CLOUD TO WATER LIGHTNING. .RIP CURRENT IMPACT... A SMALL LONG PERIOD EAST SWELL WILL PRODUCE AN ELEVATED THREAT FOR RIP CURRENTS AT THE BEACHES OF EAST CENTRAL FLORIDA. ALWAYS SWIM WITHIN SIGHT OF A LIFEGUARD. .DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY. AN ELEVATED RIP CURRENT RISK WILL PERSIST MUCH OF THIS WEEK. INCREASED MOISTURE IS FORECAST TO LIFT NORTHWEST ACROSS CENTRAL FLORIDA MID WEEK AND BRING HIGHER RAIN AND STORM CHANCES MORE TYPICAL FOR THIS TIME OF YEAR. SCATTERED LIGHTNING STORMS ARE EXPECTED EACH AFTERNOON FOCUSED OVER THE INTERIOR SECTIONS WITH THE COLLISION OF THE EAST AND WEST COAST SEA BREEZES. .SPOTTER INFORMATION STATEMENT... SPOTTERS ARE REQUESTED TO MONITOR THE WEATHER AND SELF ACTIVATE IF NEEDED. KELLY/MOSES
