The episode as NWS MLB wrote it up.
Several severe thunderstorms developed within a moist environment due to interactions of numerous sea breeze and outflow boundaries. One early afternoon storm near the coast downed several large tree limbs. A collision of the east coast and west coast sea breeze boundaries across the central Florida interior resulted in several severe storms which produced large hail, up to golf ball size over Orange and Seminole Counties during mid evening.

ATMOSPHERE REMAINS RELATIVELY MOIST WITH MORNING SOUNDING PWATS COMING IN AT 1.8" AND 1.6" AT KXMR AND KTBW RESPECTIVELY. SLIGHTLY MORE MOISTURE WILL LIKELY MEAN EARLIER INITIATION ALONG EAST COAST SEABREEZE...ESPECIALLY FOR SOUTHERN BREVARD AND THE TREASURE COAST. SOUTH-SOUTHWEST FLOW INTO THE MID LEVELS WILL DELAY THE INWARD PROGRESSION OF THE EAST COAST SEABREEZE...ESPECIALLY ALONG THE VOLUSIA COUNTY COAST INTO MID AFTERNOON. LIFT PROVIDED BY INLAND PROGRESSION OF SEA BREEZE BOUNDARY WILL SERVE AS AN AFTERNOON MECHANISM FOR DEVELOPMENT OF DEEP CONVECTION WITH ADDITIONAL SFC BOUNDARIES PROMOTING DEVELOPMENT OF STORMS INTO THE EVENING AS THEY DRIFT TOWARD THE EAST COAST. STRONGER STORMS THIS AFTERNOON WILL BE POSSIBLE ALONG ANY BOUNDARY COLLISIONS WITH WIND GUSTS UP TO 50MPH...FREQUENT LIGHTNING AND SMALL HAIL. EARLY EVENING SEABREEZE COLLISION EXPECTED AGAIN JUST EAST OF THE ORLANDO METRO IN THE ST JOHNS RIVER BASIN.

SCATTERED LIGHTNING STORMS WILL DEVELOP DURING THE EARLY AFTERNOON ACROSS EAST CENTRAL FLORIDA AND MOVE NORTHEAST.

A MERGER OF EAST AND WEST COAST SEA BREEZE BOUNDARIES LATE THIS AFTERNOON COULD LEAD TO THE DEVELOPMENT OF STRONG STORMS. THE PRIMARY HAZARDS WILL BE THE POSSIBILITY OF FREQUENT LIGHTNING...WIND GUSTS TO 50 MPH AND SMALL HAIL. ...FLOOD IMPACT... SOME STORMS WILL BE CAPABLE OF PRODUCING TWO TO LOCALLY THREE INCHES OF RAIN IN A RELATIVELY SHORT PERIOD LATE THIS AFTERNOON AND THIS EVENING. THE POTENTIAL FOR HEAVY RAIN WILL BE HIGHER MAINLY SOUTH OF THE INTERSTATE FOUR CORRIDOR. STANDING WATER ON ROADWAYS AND LOW SPOTS WILL MAKE DRIVING HAZARDOUS.
