The episode as NWS MLB wrote it up.
Local wind shift boundaries collided and resulted in persistent heavy rain from thunderstorms from south central Orange County southward to western Osceola County. Quarter sized hail fell in St. Cloud.

NWS Melbourne, FL wrote its last area forecast discussion before the first event at Jun 14, 2:40 PM EST, 4 hours 10 minutes earlier.
Area Forecast Discussion National Weather Service Melbourne FL 340 PM EDT TUE JUN 14 2016 .DISCUSSION... ...Hot and Humid into this evening with scattered storms... Currently-Tonight...Scattered showers and lightning storms are expected to continue to develop along the west coast sea breeze moving into Lake county during the late afternoon with also continued development along the east coast sea breeze which is moving only slowly inland...west of I-95 from MLB south and closer to the coast across Volusia county. Should see boundary collisions into the evening hours from inland Volusia across metro Orlando into Osceola county before diminishing into late evening. Steering winds will be from S-SW with a chance of some storms making it to Volusia county coast into the late evening. Will keep highest pops in the high scattered range from 40-50 over mainly the interior with lowest pops along far south cstl sections (~20 pct). Light south flow is forecast with winds becoming sw toward morning. Lows in the mid 70s with some lower 70s across the srn interior. Wed...Deep layer SW flow on Wednesday is expected as low lvl ridge axis slips south of the FL peninsula. Increasing moisture levels (to 1.8 to 1.9 inch precipitable water values) are fcst across nrn sections where active west coast sea breeze should move into nrn sections by late afternoon. Across the Treasure coast...GFS indicates much drier airmass with PWATS around 1.5 inches. Will favor highest rain chances across nrn areas to around 40 pct and 20- 30 pct across the far south. The sea breeze will likely be pinned near the Volusia coast but should move slowly inland south of Melbourne with isolated to scattered convection along it. Highs will reach the lower 90s along the coast and near 94 across the interior. Thu...Mid level trough will extend from the Carolinas into the northeast Gulf of Mexico with sfc low pressure moving east from the NC coast. Tightening pressure gradient will produce WSW flow to near 15 mph and not allow the east coast sea breeze to develop. Will keep rain chances in the 40-50 pct range with diurnal convection moving from the interior toward the Atlantic from late morning through the afternoon hours as a diffuse west coast sea breeze pushes across the central peninsula twd east central Florida. With the offshore flow...high should reach the lower 90s near the east coast with around 90 across Lake county. Previous Extended Discussion...Fri-Mon...a center of low pressure should form in vicinity of the Carolinas Fri and move seaward but trail an elongated trough. A secondary center is forecast to develop over the Carolina waters on Sat with additional lowering of pressure over the NE Gulf of Mexico per GFS. The ECMWF generally agrees with the development of the secondary low but ejects it northeast from the area more readily. Thus some uncertainty in the upcoming weekend's local conditions and flow regime. Regardless, banded moisture will need to be dealt with as tapped by afternoon heating and diabatic release. Sct-Lkly pops will suffice but will need to monitor flow trends for convective distribution. Max temps U80s/L90s. Min temps L/M70s. && .AVIATION... Scattered TSRA will affect interior terminals 20z-23z as activity converges on interior portions of e central FL with inland moving sea breezes. Isold-sct activity behind the sea breeze boundary should push inland from cstl terminals but may affect KDAB-KTIX corridor thru 23z. Expect diminishing trend to shra/tsra coverage by 01z-02z with VFR conditions expected from late evening and overnight. && .MARINE... Tonight...S-SW winds will increase to 10-15 knots overnight and then decrease some toward morning. seas to 2 ft nearshore and building to 2-3 ft offshore. Wed...Southwest winds early will become southerly through the day with seas to 2-3 ft offshore early decreasing into the afternoon. Chance of storms affecting the intracoastal waters late in the day mainly north of Melbourne. Thu-Sun...Strengthening offshore flow is forecast into late week as a series of low pressure systems push off the mid Atlantic coast. Winds may reach SCEC level Friday with seas up to 5 ft offshore. A frontal boundary is forecast to drop south toward the area late Saturday and move through the waters by Saturday night. Higher storm chances are forecast with the approaching front Saturday and possibly continuing across the srn waters into Sunday. Wave models forecast larger NE swells reaching the waters by Sunday with a long fetch of stronger NE-ENE winds north of the area behind the front over the weekend. && .PRELIMINARY POINT TEMPS/POPS...
