The episode as NWS MFL wrote it up.
Deep tropical moisture with light wind flow across the region. A stalled front across north central Florida and a mid-upper level shortwave moving through the region with cold temperatures aloft. 500 mb temperatures were around -8C, this allowed for some robust convection to be able to develop across the east coast metro. Storms produced hail across Miami-Dade and a brief tornado in Palm Beach County.

NWS Miami, FL wrote its last area forecast discussion before the first event at Jul 25, 12:37 PM EST, 38 minutes earlier.
Area Forecast Discussion National Weather Service Miami FL 137 PM EDT Thu Jul 25 2019 .AVIATION... Convection has already initiated across South Florida and should continue through the afternoon and early evening hours. The east coast sea breeze is having difficulty developing, which may lead to cells becoming slow moving to stalled along the Atlantic metro areas. Some of the TS may become strong to near severe. Some isolated downbursts may exceed 45kts this afternoon, and possibly reach to near 55kts. Convection should begin to move offshore in the late evening hours. && .PREV DISCUSSION... /issued 843 AM EDT Thu Jul 25 2019/ UPDATE... Updated forecast with latest Hi res models. Most of the models are already placing chance PoPs across the area, even though there is little to no activity on Radar at this time. So, kept no to low PoPs through the morning hours, and increase the quickly early this afternoon, especially over the east coast. The wind fields are hinting that there could be some convergence over the east coast metro area today. this could lead to some training, or slow moving to staled convective cells over the metro area. this could lead to some urban street flooding, mainly due to poor drainage and in low laying areas. 500 mb temps this morning are at -7.5C with 700-500mb lapse rates at 6.3. this would support the unstable nature of the atmosphere today. The NCAPE is only .13 today. However, modifying the sounding so todays forecast high temperature, the NCAPE goes up to .28. This would indicate good vertical velocity with the storms, which would be able to support cores at higher levels, allowing for a better chance of some downburst winds which would be at least SPS level (45mph+) this afternoon. Also, there may be a non zero chance of an isolated downburst at severe levels. However, this again is unlikely, but not impossible today. PREV DISCUSSION... /issued 300 AM EDT Thu Jul 25 2019/ .A FEW STRONG STORMS POSSIBLE INTERIOR/EAST COAST AREAS THIS AFTERNOON... .MORE OF A TYPICAL SUMMER WEATHER PATTERN RETURNS THIS WEEKEND INTO NEXT WEEK... DISCUSSION... TODAY AND TONIGHT... A stationary front located over North Central Florida will remain nearly stationary through tonight allowing for the south/southwest wind flow to remain over South Florida. However, the weak synoptic flow in the low levels will be less than 10 knots today allowing for the east coast sea breeze to push further into the metro areas than yesterday. This in turn will allow for more coverage of the showers and thunderstorms over the interior and east coast metro areas this afternoon compared to Wednesday coverage. Therefore, POPs will remain in the scattered to numerous range over the interior/east coast metro areas with mostly scattered POPs over the west coast metro areas for today. The storms should slowly dissipate this evening as the heating of the day is lost, but could continue over the local waters through the night hours. The mid levels will also remain on the cool side over South Florida today as the 500 temps will be around -8C. This will allow for a few of the storms over the interior and east coast areas to become strong this afternoon into early this evening with gusty winds, small hail, frequent lightning strikes, and locally heavy rainfall. FRIDAY INTO THIS WEEKEND... Friday will be a transition day over South Florida as the winds will swing more to a southeast direction, due to the high starting to build into the Florida Peninsula from the Western Atlantic waters. This will focus the best showers and thunderstorms over the interior areas, but the metro areas could still see some showers and thunderstorms. The high will remain over the Western Atlantic waters this weekend keeping the steering flow easterly over South Florida. This will allow for a more typical summer weather pattern with late night/morning showers and thunderstorms over the east coast metro areas shifting to the interior/west coast metro areas in the afternoon and evening hours. EXTENDED FORECAST... The weather pattern will not change much over South Florida next week, as the high will remain over the Western Atlantic waters keeping the easterly wind flow in place. Therefore, the weekend weather pattern will continue into next week for South Florida. MARINE... The winds will remain south/southwest over South Florida waters today into tonight before swinging to more of a easterly direction this weekend. The wind speeds will remain at 10 knots or less over all of the local waters of South Florida. This will keep the seas at 2 feet or less in both the Atlantic and Gulf waters through the weekend. Therefore, mariners can expect good conditions outside of any showers or thunderstorms through this weekend. AVIATION... Scattered to numerous thunderstorms are expected this afternoon and evening. The greatest storm coverage is forecast across east coast area TAF sites -- reflected by VCTS mention given uncertainty in storm impacts at any specific site. Higher- confidence thunderstorm mention may be needed for specific TAF sites in later forecasts if confidence improves. Strong winds, and visibility and ceiling restrictions, are possible with storms. Otherwise, occasionally breezy south to southwest winds and VFR conditions are expected. && .PRELIMINARY POINT TEMPS/POPS...

Storm potential will continue into the overnight hours over the South Florida waters. The greatest coverage of thunderstorms is expected to be across the east coast metro areas and vicinity, including the adjacent coastal Atlantic waters. Thunderstorms will be capable of producing strong winds, heavy rain, and frequent lightning. Waterspouts: The potential for isolated waterspouts will exist over the South Florida waters for today and tonight. Wind: The strongest thunderstorms could produce wind gusts of 45 to 55 mph. An isolated severe thunderstorm capable of producing damaging winds could occur, especially over the east coast metro areas and vicinity. Flooding: Localized flooding will be possible, especially where multiple storms move over the same locations. This potential is highest across the east coast metro areas. Temperatures: Heat indices are forecast to reach around 100 to 106 degrees this afternoon, with the highest of these readings expected over interior sections of South Florida. .DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY Scattered thunderstorms are expected each day through the period across the outlook area. Frequent lightning, locally heavy rain, and gusty winds will be the main hazards with these storms. This activity will have a general tendency of focusing over interior and western sections of South Florida through the period. Additionally, heat indices could reach around 100 to 107 degrees each afternoon through the period, with the highest of these readings expected over interior South Florida. .SPOTTER INFORMATION STATEMENT... Widespread spotter activation is not anticipated, however individual spotters are encouraged to report high wind, waterspouts, and flooding to the National Weather Service Forecast Office in Miami.
