The episode as NWS MFL wrote it up.
Cold air aloft coupled with afternoon heating led to the development of sea breezes which focused strong to severe thunderstorms over SW Florida during the afternoon.
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 Aug 3, 1:26 PM EST, 3 hours 6 minutes earlier.
Area Forecast Discussion National Weather Service Miami FL 226 PM EDT Wed Aug 3 2022 ...New SHORT TERM, LONG TERM, AVIATION, MARINE... .SHORT TERM... (This evening through Thursday) Issued at 224 PM EDT Wed Aug 3 2022 An expansive surface ridge of high pressure remains in firm control of our weather pattern as persistent southeasterly flow continues to prevail across our area. Ample insolation and diurnal heating will allow for the continued development of shower and thunderstorm activity throughout the afternoon and early evening hours. Interestingly enough, several parameters hint at robust convective development later this afternoon which could support the potential of a few storms on the stronger side. The latest 12z RAOB MFL sounding from earlier this morning. The observed 500mb temperature on the 12z sounding was -8.5C with an environmental freezing level of 15,117 feet. This indicates the presence of a pool of colder air aloft, which when coupled with decent mid level lapse rates support the aforementioned potential of strong storms across inland areas and the Gulf coast today. CAPE and DCAPE parameters from modified soundings indicate the potential for wet microbursts to occur as convective columns collapse and downdrafts arrive at the surface. The lack of mid-level steering winds, also illustrated by a sluggish and lackluster 6kts on the corfidi upshear and downshear parameter also indicate the potential for slow moving shower and thunderstorm activity, which could result in localized flooding occurring later today. Another interesting piece of the puzzle for todays forecast is the presence of a diluted plume of Saharan Dust. NASA's Dust Aerosol Optical Thickness Model and the NRL Aerosol Model both indicate Saharan Dust continuing to persist across our area today, which also line up with current satellite imagery observations. This has acted to create a weak capping inversion across our area this morning, which will act to suppress vertical motion until it is eroded with enough diurnal heating. This capping mechanism may act to enhance convection as developing updrafts are able to tap into a much more favorable environment once they are able to break through the cap. In spark notes terms, various parameters are pointing to the potential of a few storms on the stronger side later this afternoon across the western half of South Florida. While most activity should remain below severe thresholds, wet microbursts may lead to some gusty to strong winds across affected areas. There is also the potential for localized flooding to occur as overall steering remains light, especially across areas that receive repeated rounds of heavy rainfall. High temperatures today will range from the upper 80s along the immediate east coast to widespread low 90s across much of the rest of the region. Locations that experience heavy rainfall and the cooling impacts of convection may see rapid temperature fluctuations as rain cooled air filters down to the surface. CAMs and forecast soundings indicate the potential of a new surge of moisture advecting into South Florida during the early morning hours of Thursday. Shower and thunderstorm activity will likely increase over the Atlantic waters during the overnight hours before activity pivots to the eastern half of South Florida during the mid to late morning hours. While some mesoscale models have trended on the higher side for this time period, I have capped PoPs in the 40-50% range along the east coast at this time to account for uncertainty. Shower and thunderstorm chances will then transition inland and towards the Gulf coast due to the prevailing southeasterly flow. Gusty winds, heavy rainfall, and frequent lightning remain potential hazards with thunderstorm activity on Thursday afternoon. High temperatures will be similar in nature to today with highs in the upper 80s to low 90s across the region. && .LONG TERM... (Thursday night through next Tuesday) Issued at 224 PM EDT Wed Aug 3 2022 Mid/Long range model guidance continues to reveal a prominent western Atlantic ridge that should maintain deep east/southeasterly flow across South Florida for the end of the week and through the weekend. This regime should present an environment characterized by seasonable moisture values, with models parsing precipitable water indices around 1.6 to 2.0 inches. A few subtle inverted low-level troughs could allow for localized moisture convergence that sparks bursts of convection through the weekend/early next week. The nature of this pattern may allow for showers and thunderstorms that do not align with the typical diurnal cycle; however impacts should be limited to lightning and locally gusty winds. Sunday/Monday may present a more robust environment for storms - characterized by cold temperatures aloft (-8/-9C) and steepened mid-level lapse rates (7 C/km) - as an upper level TUTT low lingers over the western Atlantic waters. Latest NBM guidance appears too aggressive on PoPs (not accounting for intermittent advection of drier air), and thus PoPs have been capped up to 50-60 across much of the region through Sunday. Nature of winds and general flow continues to favor greatest activity over the western half of the CFWA. By early next week, the continuance of east/southeasterly flow regime should allow deep tropical moisture to overspread the region. The flow regime will continue to favor convective activity over the interior/west coast region, primarily during the afternoon and evening hours. Locally elevated wind gusts and lightning remain as the primary hazards to consider through this period. Maximum temperatures should remain seasonable to seasonably warm, with the warmest temperatures expected over the western half of the region. Daily afternoon maximum temperatures should range from the upper 80s/lower 90s along the east coast, and low/mid 90s elsewhere across the region. && .AVIATION... (18Z TAFS) Issued at 224 PM EDT Wed Aug 3 2022 SHRA/TSRA will continue to increase in aerial coverage across inland areas of South Florida over the next several hours. While most of the activity should remain across the interior, a few SHRA/TSRA could potentially affect KAPF later today. Thus, have handled with VCTS for now but TEMPOs may be needed later if confidence increases. Southeasterly flow through the early evening hours before L/V conditions overnight. && .MARINE... Issued at 224 PM EDT Wed Aug 3 2022 Winds outside of showers and thunderstorms are expected to be mainly east around 10 knots through Thursday, then increase later in the week and weekend to around 15 knots as the high pressure strengthens over the Atlantic and increases the pressure gradient across South Florida and the local waters. Showers and thunderstorms will be most numerous in the Gulf waters during the late afternoon and evening, while over the Atlantic waters most of the activity will be in the night and morning hours throughout the period. && .PRELIMINARY POINT TEMPS/POPS...
