The episode as NWS MFL wrote it up.

The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Miami, FL wrote its last area forecast discussion before the first event at Jun 13, 1:46 PM EST, 1 hour 44 minutes earlier.
Area Forecast Discussion National Weather Service Miami FL 246 PM EDT Tue Jun 13 2023 ...New LONG TERM... .SHORT TERM... (Rest of today through Wednesday) Issued at 116 PM EDT Tue Jun 13 2023 The set up for South FL the next couple of days features upper level high pressure over the western Gulf and central Atlantic, and an upper low over the Great Lakes region. Several weak impulses will pass across the area today and tomorrow which may aid in some convective development, however convection is expected to be primarily diurnally driven peaking during the afternoon and early evening hours each day. Morning 12Z MFL sounding showed weak effective shear and lapse rates, however those lapse rates should improve this afternoon during peak heating. HREF guidance from 12Z shows MUCAPE values of 2500-3000 J/kg and DCAPE values around 1000 J/kg this afternoon. This suggests that a few stronger storms may be possible today, with strong wind gusts the primary threat. Weak steering flows will also present a localized flooding risk, especially across the east coast metro. With high temps in the lower 90s and dew points in the mid to upper 70s, heat index values will be in triple digits and will hit criteria in some locations, but not long enough and over a large enough portion of the counties to warrant an adv today. Regardless though, those with heat sensitivities will want to limit outdoor activities through early this evening. Convection dissipates this evening with partly cloudy skies expected overnight. It'll be another very mild night with low temps in the lower 70s around the lake, to upper 70s across the metro. The flow becomes more southerly on Wednesday which will allow dew points to tick up another degree or two. There's a better chance for heat adv criteria to be met, although timing and coverage of convection will play a role in how much of the area can actually achieve criteria for at least a couple hours. Afternoon high temps will range from 90- 95 across much of the area. && .LONG TERM... (Wednesday night through next Monday) Issued at 246 PM EDT Tue Jun 13 2023 The expanding high over the Western Atlantic and mid-to-upper level ridging over the Gulf of Mexico extending into the Florida Peninsula, Thursday and Friday should see a break from convective showers and thunderstorms across the region. Moisture availability will generally be around average, so there will remain the possibility for a few pulse showers and storms caused by the sea breezes and peak heating. However, these should be short lived due to large scale subsidence. Low-level winds will continue to be out of the S/SW both Thursday and Friday and thus it will become very hot with the ridging, southerly winds and clearer skies. Temperatures are expected to reach the mid 90s with dew points in the 70s and thus heat indices have a good chance to reach advisory criteria both days. As we enter the weekend, long term guidance is hinting at our next shortwave trough advecting through the area and providing a source of lift for the hot, moist and unstable air. As a result, potential for more widespread showers and storms that lead to heavy rain, localized flooding, gusty winds and frequent lightning will be possible this weekend. After that, early next week is much more uncertain but active weather looks to continue. && .AVIATION... (18Z TAFS) Issued at 116 PM EDT Tue Jun 13 2023 SCT thunderstorms this afternoon through early this evening may result in brief flight restrictions and erratic winds. Southerly winds 10-15 kts becoming light and variable overnight. Additional showers and storms are expected on Wednesday, mainly during the afternoon into early evening. && .MARINE... Issued at 116 PM EDT Tue Jun 13 2023 Generally benign conditions will be present through the end of the week as high pressure remains in control. South to southwest winds 5- 15 kts through Friday. Seas generally 2 ft or less. Scattered thunderstorms possible each day which may result in locally hazardous winds and seas. && .PRELIMINARY POINT TEMPS/POPS...
