The episode as NWS MFL wrote it up.
As a surface frontal boundary pushed southward through the southeastern United States, winds began to veer south-southeast bringing moist, warm air into South Florida. This supported the development of numerous showers and thunderstorms across the area throughout the day.
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 Sep 3, 1:50 PM EST, 2 hours 17 minutes earlier.
Area Forecast Discussion National Weather Service Miami FL 250 PM EDT Tue Sep 3 2024 ...New LONG TERM... .SHORT TERM... (Rest of today through Wednesday) Issued at 1238 PM EDT Tue Sep 3 2024 A stationary frontal boundary will remain stalled across northern Florida through the mid-week period, keeping abundant moisture pooled across the entire state of Florida. From an overall pattern point of view, South Florida sits underneath a mid-to-upper level ridge centered over the Caribbean, which is favoring continual deep moisture advection that becomes trapped south of the front. The latest ACARS soundings highlight the expected high moisture content with PWATs between 2.3-2.5 inches. In addition, there is plenty of instability (generally around 2000 J/kg SBCAPE and 3000 J/kg MUCAPE) for storms to grow. The 12Z MFL sounding showed highly similar values as well. Therefore, even with a large high pressure influence from the ridge, diurnal effects and the aforementioned parameters in place will lead to another day of numerous showers and thunderstorms. A steady east-southeast flow will occur underneath the ridge, favoring the heaviest and strongest storms towards the Gulf coast and western interior where the strongest convergence occurs. Between slow storm motions, high rainfall rates, and saturated grounds, localized flooding will again be a concern today particularly for poor drainage areas. Heading into Wednesday, the large scale pattern will remain similar. The ridge will begin to shift further west and is expected to strengthen the easterly flow, which should force some of the excess moisture out of the area and drop PWATs to the 1.8-2.1 inches range. However, around 2 inches still shows that plenty of moisture will be leftover and another day of scattered showers and thunderstorms will occur. The low level easterly flow will once again favor Gulf coast and western interior areas with chances again for localized flooding concerns. Temperatures for today are expected in the upper 80s to around 90 with heat indices expected below advisory levels due to rain and cloud cover. On Wednesday, temperatures should rise a few degrees and hit the low 90s across the region. With slightly drier conditions likely on Wednesday, heat indices could rise to advisory levels particularly for west coast and interior portions of South Florida. && .LONG TERM... (Wednesday night through next Monday) Issued at 249 PM EDT Tue Sep 3 2024 A mid-level ridge building over the Florida Peninsula will be the dominant synoptic feature for the end of the week, supporting a warming and slight drying trend through Friday. A minor intrusion of Saharan dust during this period will drop PWAT values to around 1.75-2", which will still support scattered to numerous showers and thunderstorms each day. Moderate southeast flow in the low to mid-levels will generally lead to a pattern of isolated showers or storms over the Atlantic waters and East Coast metro in the morning, becoming scattered and focusing over the interior and Gulf Coast by the afternoon. Heat will likely be a bigger concern than the storms during this period, with high temperatures in the low to mid 90s, and peak heat indices ranging from 105-111 each day. Over the weekend and into next week, mid-level troughing will drop across the Eastern US, kicking the ridge east, out over the Caribbean. A frontal boundary associated with the trough will push through the Southeast US, but stall out over North-Central Florida. This will cool things off a little bit, but keep a moist airmass pooled over South Florida, supporting elevated rain chances. Low-level flow still looks like it will be out of the southeast, with a convective pattern that typically looks like isolated overnight showers, with scattered to numerous showers and storms from late morning to afternoon focused over the interior and Gulf Coast. Temperatures will be a bit more seasonable during this period, with highs in the upper 80s, and peak heat index values around 100-105. && .AVIATION... (18Z TAFS) Issued at 1238 PM EDT Tue Sep 3 2024 Showers and thunderstorms will increase in coverage this afternoon, likely focusing more towards KAPF with time. That said, scattered showers and isolated thunderstorms will still be possible for east coast terminals all afternoon. Brief flight restrictions are possible in and around stronger storms. SE winds around 10kts are expected this afternoon and evening. && .MARINE... Issued at 1238 PM EDT Tue Sep 3 2024 Moderate east-southeast winds will continue across most of the local waters through the middle portion of the week. Seas across the Atlantic waters will remain at 3 feet or less while seas across the Gulf waters remain at 2 feet or less. Scattered to numerous showers and thunderstorms will be possible each day. Winds and seas could be locally higher in and around showers and storms. && .BEACHES... Issued at 1238 PM EDT Tue Sep 3 2024 There is a moderate risk for rip currents for the Atlantic coast today with steady onshore flow in place. The rip current risk will continue to be elevated through most of the week as onshore flow continues. && .PRELIMINARY POINT TEMPS/POPS...
