The episode as NWS MFL wrote it up.
Mid-level troughing over the Florida Peninsula combined with sea breeze boundaries and plentiful moisture led to another afternoon and evening of scattered showers and thunderstorms on May 29th.
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 May 29, 1:56 PM EST, 1 hour 54 minutes earlier.
Area Forecast Discussion National Weather Service Miami FL 256 PM EDT Wed May 29 2024 ...New LONG TERM... .SHORT TERM... (Rest of today through Thursday) Issued at 124 PM EDT Wed May 29 2024 Scattered to numerous showers and thunderstorms will develop along the sea breeze boundaries this afternoon, with chances for localized flooding, gusty winds and small hail possible across southeast FL. Data from the MFL 12z sounding and ACARS flights depict an atmosphere primed for convective activity and potential thunderstorm impacts, with MUCAPE > 2000 J/kg, surface lapse rates > 6 C/km, DCAPE > 1000 J/kg and PWATs > 1.65 inches, which could result in damaging wind gusts and small hail with some of the stronger thunderstorms. At this time, the limiting factor for hail development are the mid level temperatures which remain above -10C. The above-average PWAT values, combined with modest westerly- northwesterly steering flow aloft, could result in an enhanced flooding threat for East Coast metro areas late this afternoon as storm clusters form and propagate from northwest to southeast. Temperatures will remain hot and humid day (prior to convective initiation) with highs ranging from the low 90s near the immediate coasts to the upper 90s in the Interior, along with widespread peak heat indices of 100-105 degrees. The main change to the setup for Thursday will be the synoptic flow gradually trending more easterly, favoring convective progression towards the Interior and eventually west coast (as opposed to the last few days) Thursday afternoon. Once again gusty winds will remain the main threat with any storms, although a widespread organized severe threat looks unlikely (and any heavy rainfall threat will be tempered by antecedent dry conditions). One impact of the more notable easterly flow will be the start of a slight cooling trend for the east coast, with highs dropping a couple degrees relative to Wednesday (albeit still above normal), although temperatures likely remain similar over the Interior/west coast. && .LONG TERM... (Thursday night through next Tuesday) Issued at 255 PM EDT Wed May 29 2024 The setup for Friday will be similar to Thursday with light easterly synoptic flow prevailing, favoring the highest rain chances over the Interior and west coast and similar temperatures to Thursday. Heading into the weekend high pressure north of the area will build southward, likely pushing the previously-stalled front through the area as a weak backdoor cold front. This will usher in a shift to a moderate easterly regime Saturday which should persist into the start of the upcoming workweek. A drier (particularly at the mid- lvls) and more stable airmass will filter in behind the boundary which will limit thunderstorm chances (particularly for the east coast), with any rain likely of the shallower quick-moving shower variety. Temperatures will also come down a few degrees with highs in the mid to upper 80s over the east coast, and lower 90s over the Interior and west coast, with dewpoints also coming down a bit to keep heat indices depressed relative to the recent very high values. This setup looks to largely remain in place through the beginning of next week as surface high pressure remains situated off the Carolina coast and the Gulf. As a result, further daily convection will be limited to sea and gulf breeze development each afternoon. Temperatures will begin to slowly increase by a degree or two each day as well. && .AVIATION... (18Z TAFS) Issued at 124 PM EDT Wed May 29 2024 Periods of MVFR/IFR conditions with VCSH/VCTS for East Coast TAF sites this afternoon which could require short-fuse TEMPOs. Otherwise, VFR conditions will generally prevail through the period. SE winds around 10kt along the Atlantic sites, with the westerly Gulf breeze at APF. Winds go light and variable overnight. && .MARINE... Issued at 124 PM EDT Wed May 29 2024 Mostly benign boating conditions will continue as light sea-breeze- induced flow prevails across all local waters (ESE over the Atlantic waters, W over the Gulf waters). Seas will remain at or below 3 feet. Isolated to scattered showers and storms each afternoon could result in localized higher seas and winds. Winds will increase out of the east late this week into the upcoming weekend with increasing seas over the Atlantic waters by the weekend. && .PRELIMINARY POINT TEMPS/POPS...
