The episode as NWS MFL wrote it up.
A stationary frontal system positioned over the southeastern United States led to plentiful moisture and instability which resulted in conditions for numerous showers and thunderstorms throughout the day across southern Florida.
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 8, 1:44 PM EST, 1 hour 31 minutes earlier.
Area Forecast Discussion National Weather Service Miami FL 244 PM EDT Thu Jun 8 2023 ...New LONG TERM... .SHORT TERM... (Rest of today through Friday) Issued at 110 PM EDT Thu Jun 8 2023 Latest analysis shows surface high pressure over the central Atlantic, and a frontal boundary over the SE states with several areas of low pressure riding along the front. At the upper levels, there is low pressure over upper New England and a trough to our west over the Gulf. With the surface high to our east, the low level flow will be S/SW today, and plenty of moisture is streaming into South FL from the SW ahead of the trough in the Gulf. PWAT values off the 12Z MFL sounding are already 1.9 inches and should remain in that region today. One weak disturbance is moving through the area early this afternoon with a round of convection, and then additional convection is expected to move mainly from west to east later this afternoon into this evening. While storms will be efficient rain makers today, the progressive nature of storms will limit the flooding potential, however some isolated instances will still be possible over the east coast metro if boundary interactions cause training of storms over the same area. With DCAPE values once again around 1000 J/kg today and effective shear of 30-40 kts, a few strong to borderline severe storms can't be ruled out, with strong wind gusts the primary threat. Convection wanes this evening with the loss of daytime heating, however scattered showers and storms will remain along the coasts and far southern peninsula. It'll be another warm and muggy evening, with low temps around 70 near the lake, and mid to upper 70s across the metro. On Friday the frontal boundary over the SE states will slowly slide south towards northern FL and the upper level trough axis over the Gulf will move closer to the area. A W/SW flow is expected across the area, albeit a bit weaker than today. Convection will again favor interior and SW FL earlier in the day and then favor the east coast metro later in the day. With the weaker flow, an Atlantic breeze will try to make a push in the afternoon across the metro. Severe and flooding threat again looks limited, with the best chances likely occurring along the sea breeze and any boundary interactions. High temperatures will range from the upper 80s to lower 90s. && .LONG TERM... (Friday night through next Wednesday) Issued at 232 PM EDT Thu Jun 8 2023 Fairly unsettled long term period as strong mid-upper level troughing will dominate the longwave pattern across the eastern CONUS. A frontal boundary associated with a strong upper level cyclone over the Northeast will be stalled across northern Florida to open the period keeping the Southern Florida under a south- southwesterly regime through the majority of the weekend as this boundary lingers and fizzles to the north. With enhanced moisture transport, PWATs will remain in the 1.6 to 2 inch range which is above average for this time of year. This will favor scattered showers and thunderstorms across the interior and eastern portions of South Florida each afternoon through the weekend. By the end of the weekend, another upper level cyclone begins to deepen across the Great Lake States by early Monday morning. This system will drift east-southeast and will bring another frontal boundary towards the Florida peninsula keeping the area under enhanced south- southwesterly flow through the beginning portion of next week. This should keep above-average PWATs across our area and support scattered (to perhaps numerous at times) showers and thunderstorms favored across interior and eastern South Florida. Towards the end of the long term period, the Bermuda high begins to strengthen and surface flow will subsequently try to veer more east to southeasterly by late Wednesday although depending on how this feature evolves, we may not return to an easterly regime until later on in the month. High temperatures will range from the upper 80s to lower 90s each afternoon with heat indices potentially approaching 100. && .AVIATION... (18Z TAFS) Issued at 110 PM EDT Thu Jun 8 2023 Scattered thunderstorms today will result in brief flight restrictions and erratic winds. Outside of storms, SW winds 10-15 kts relaxing to 10 kts or less overnight. Additional showers and storms are expected on Friday which may result in additional brief restrictions. && .MARINE... Issued at 110 PM EDT Thu Jun 8 2023 Generally benign conditions will be present into the end of the week. However, there will continue to be daily chances of scattered showers and thunderstorms, which could result in locally chaotic seas and gusty winds at times. Outside of convection, seas in the Atlantic generally 3 ft or less and 2 ft or less in the Gulf through Friday. && .BEACHES... Issued at 110 PM EDT Thu Jun 8 2023 There is a moderate risk of rip currents today for the Palm Beaches due to a slight NE swell. The swell dissipates later today, and with predominately off-shore flow through the end of the week, the rip risk will decrease. High tides the next two evenings will remain elevated however are expected to crest below minor flood stage along the coasts. Tide levels will continue to decrease this weekend. && .PRELIMINARY POINT TEMPS/POPS...
