The episode as NWS MFL wrote it up.
Morning storms once again developed along the east coast with the Atlantic seabreeze, with numerous storms across the interior and Gulf coast as seabreezed moved west and collided with the Gulf breeze along the Gulf coast during the afternoon hours. Shower and storm development along these boundaries was enhanced by a lingering upper level low across the northern Florida and the eastern Gulf of Mexico, allowing several strong storms to develop. Hail and a funnel cloud were reported in Palm Beach County with the morning activity, along with a lightning-induced fatality in Broward County. Hail was reported in Collier County during the afternoon hours.

Area Forecast Discussion...UPDATED National Weather Service Miami FL 938 AM EDT Mon Jun 11 2018 ...Some Strong Storms Are Possible Today Across South Florida... .UPDATE... The ridge of high pressure will remain over Western Atlantic waters while a mid to upper level low remains over the eastern Gulf of Mexico today. There is also a mid level short wave that will be moving northward across South Florida this afternoon from the Florida Keys. This weather pattern will allow for an light southeast wind flow along with scattered to numerous showers and thunderstorms over South Florida today. The best coverage should be over the interior and west coast metro areas this afternoon, due to the southeast wind flow, but the east coast metro areas will still see some showers and a few thunderstorms. The 500 mb temperatures this morning from the MIA sounding was still around -10C. These cool temperatures will remain in place over South Florida today allowing for some of the storms to become strong with gusty winds, hail, frequent lightning strikes, and locally heavy rainfall. Therefore, the HWO package will continue to mention the strong thunderstorm wording for South Florida today. Rest of the forecast looks good at this time, and no other changes are planned. && .UPDATE...54/BNB .PREV DISCUSSION... /issued 800 AM EDT Mon Jun 11 2018/ AVIATION... Light winds until 14Z east coast taf sites, then east/southeast winds 5 to 10 knots from 14Z until 00Z. KAPF winds light until 18Z, then westerly around 10 knots from 18Z until 00Z. VCSH until 14/15Z, then VCTS until 18/19Z, then back to VCSH until 00Z for east coast taf sites. KAPF taf site, could see a few showers this morning, but not enough coverage to put into forecast VCTS from 18Z until 00Z KAPF. Ceiling and vis should remain in VFR conditions, but could fall into MVFR or even IFR conditions with showers or thunderstorms. Tempo group will be added when showers or thunderstorms are near the taf sites. && AVIATION...54/BNB PREV DISCUSSION... /issued 421 AM EDT Mon Jun 11 2018/ DISCUSSION... Latest water vapor loop continues to show very weak cyclonic flow from an upper level low pressure system, centered over the central and northern portion of the peninsula. Abundant mid and upper level moisture can be seen streaming northward over Southern Florida, originating from the tropics. According to satellite derived PWATs, values average around 2.0" across the southern portion of the peninsula, indicating a very moist atmospheric column. As with the last few mornings, NWS radar displays relatively benign conditions, with only a few light showers passing over the waters. A couple lightning strikes can't be ruled out off the Atlantic coast, but not expecting anything of significance. For the remainder of today, surface high pressure near Bermuda will keep flow light and east southeasterly or southeasterly across the peninsula. This will allow for both the Atlantic and Gulf breezes to develop by late morning. The HRRR and WRF models prog shower and thunderstorm activity to develop by late morning or early afternoon as diurnal heating increases, then propagate in random directions, as outflow boundaries collide. Models are keeping the cooler air aloft over our CWA this afternoon, generally ranging from -9C to -10C at 500 mb, which should enhance thunderstorm updrafts. Dime to nickel sized hail, marginally severe wind gusts, heavy rain, and cloud to ground lightning will be the main threats with this activity. Precipitation should diminsh during the evening as diurnal heating wanes. Maximum temperatures are once again forecast in the mid to upper 80s, a few degrees below seasonal norms. Tuesday through Thursday: Surface high pressure in the general region of Bermuda will maintain the weak south or southeast flow pattern, which is typical of the wet season. Deep moisture is expected to advect over the area, as GFS forecast PWAT values reside above 1.75". Though sea breeze and diurnally driven activity will dominate, isolated nocturnal activity can not be ruled out as well. Maximum temperatures through the period are forecast in the upper 80s along the easter half of the peninsula, with lower 90s further west. Friday into the weekend: Both the GFS and ECMWF show upper level ridging sitting stagnant over the southeast CONUS. These models hint at a weak back door front staged to drop southward over the peninsula, which may act to enhance precip chances. However, the timing and strength of this feature are highly uncertain. No matter the solution, sufficient moisture and light flow pattern should keep the daily chance of showers and storms in the forecast through the extended. MARINE... A Bermuda high is forecast to generally maintain light east to southeast wind across the region well into the week. Showers and thunderstorms will be possible through the forecast period. Seas are forecast to be 2 feet or less through the end the week for both the Gulf and Atlantic waters. However, locally rough seas will be possible with and gusty showers or thunderstorms. AVIATION... Similar setup to Sun, with isold ATLC SHRA/TSRA developing through remainder of overnight, potentially close enough for VC at times. Light offshore flow should keep most activity off coast initially, but may need to include TEMPO groups as activity develops. VCSH for all east coast sites after 10Z, then VCTS developing east coast sites 15Z-17Z with east coast seabreeze. Due to outflow threat under light winds, will keep mention in through sunset, but best chances will shift west towards KAPF after 20Z. && .PRELIMINARY POINT TEMPS/POPS...

This hazardous weather outlook is for South Florida. .DAY ONE...TODAY AND TONIGHT Thunderstorms: Scattered to numerous thunderstorms are expected again across South Florida today. Activity is expected along the east coast metro through the early afternoon hours, with the highest coverage once again across the interior and Gulf coast this afternoon and evening. The primary threats are lightning, hail, gusty winds, and localized minor flooding. Waterspouts: Conditions are favorable for the development of several waterspouts over the nearshore Atlantic waters this morning, with more isolated waterspouts possible over the remainder of the Atlantic waters. Isolated waterspouts will be possible across the remainder of the South Florida waters through the rest of the day. Wind: The strongest thunderstorms will be capable of producing strong wind gusts to around 60 mph, mainly across the interior and Gulf coast with boundary collisions later today. Hail: Nickel to quarter sized hail is possible with the strongest storms today, especially over the interior and west coast metro areas. Flooding: Slow moving thunderstorms will bring the threat of minor flooding of streets and poor drainage areas, especially for urban locations across South Florida. .DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY Scattered thunderstorms are expected each day, generally along the east coast during the overnight and morning hours, and across the interior and Gulf coast during the afternoons and evenings. The primary threat will be lightning, although gusty winds and locally heavy rain are also possible. .SPOTTER INFORMATION STATEMENT... Widespread spotter activation is not anticipated, however individual spotters are encouraged to report high wind, hail and flooding to the National Weather Service forecast office in Miami.
