The radar
The Miami radar (KAMX), 32 km from the middle of the area, began a volume at 19:10 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.
Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.
Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.
The nearest sounding before it
Miami, FL (KMFL), launched 12:00Z, 7.1 hours before the alert went out and 6 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

CohenWhat forecasters said that day
The local office's own words before this severe thunderstorm warning went out, 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 this severe thunderstorm warning went out at Apr 18, 2:36 PM EDT, 32 minutes earlier.
Area forecast discussion, Apr 18, 2:36 PM EDT, 32 minutes before
Area Forecast Discussion National Weather Service Miami FL 236 PM EDT Sat Apr 18 2020 .Short Term... Late Afternoon Through Sunday night... A low amplitude wave, now evident in moisture channel imagery, will progress through the Southeast CONUS this afternoon and evening. A 60 kt mid-level wind max will accompany the wave, as a thunderstorm complex now over the eastern Gulf of Mexico moves across the Florida Peninsula. Satellite derived precipitable water values this morning show a reservoir of available moisture (values at or above 2 inches) which will advect into the northern and eastern portions of the NWS Miami CWA this afternoon. While the greatest mid-level height falls, jet-level divergence, and cyclonic vorticity advection, and deep layer shear will remain to our north (closer to the advancing shortwave), there are a few factors suggesting that a severe weather and/or flooding risk may exist across northern and eastern portions of our area today. First, analysis of the 18.12z MFL sounding suggests surface based instability is already on the order of 1000 J/kg, with little inhibition. Capping aloft is negligible with plentiful insolation, suggesting a favorable environment for thunderstorm development with additional warming/moistening today. While model forecast mid-level lapse rates appear modest, heating within the lower troposphere is forecast to boost low-level (0-3 km) lapse rates over 8 C/km this afternoon. The aforementioned warming/moistening suggests plentiful buoyancy today as MLCAPE rises to around 2 kJ/kg. Additionally, a pinned east coast sea breeze should serve as a low-level focus for ascent, with outflow boundaries providing an additional focus after convective initiation. Given forecast theta-E differentials and 900 J/kg of DCAPE strong to locally damaging downburst winds appear to be a primary hazard with sufficient precipitation loading taking place within the more robust thunderstorm updrafts. Hail is also possible in the taller cores. There is also a secondary (albeit more conditional) concern for a tornado or two given potential boundary collisions along with the localized backing of the low- level winds associated with the sea breeze boundary. The areas most likely to see strong to severe storms this afternoon appears to align well with the recently updated Day 1 Outlook from the Storm Prediction Center, which places a slight risk for severe thunderstorms across the eastern half of Palm Beach County, with a marginal risk continuing south across eastern Broward and into northeast Miami- Dade Counties. Given antecedent rainfall on the order of 2-3 inches over portions of Palm Beach County, flooding is also a concern should convection repeatedly affect any of these areas. The pinned sea breeze suggests we'll also need to watch coastal/metro Broward and Miami-Dade Counties for flooding potential as well. Showers and thunderstorms should gradually diminsh over land areas this evening as the upper wave departs, but may continue for a time over the Atlantic waters tonight. Patchy fog is possible over inland areas late tonight into Sunday morning. Warm weather continues on Sunday, with highs in the 90s away from the coasts. Scattered showers and a few thunderstorms are possible, with the greatest chances from the Lake region towards Palm Beach County. .Long Term... Monday through Friday night... Monday will start off with a 500mb short wave well to the north of the area. Associated with this short wave is a surface low, which should be off the Mid-Atlantic coast by Monday at 12z. A cold front associated with this low should be stretched back to the east southeast, over Central Florida. just ahead of this front, the models are showing the weather to be quiet the first half Monday. As the front slides to the south, showers and thunderstorms moving into the wester lake region by Monday afternoon. The front continues to push south Monday night, allowing for more widespread chance PoPs for Monday night. On Tuesday, the front stalls somewhere over South Florida, but begins to wash out, as the actual low moves well away from the CONUS. This would allow for some chance PoPs, especially over the eastern half of the CWA on Tuesday. By Tuesday night, high pressure builds to the north, allowing for quieter weather Tuesday night through Thursday morning. Thursday morning will see a 500 mb short wave moving well north of the area once again. At the surface, an area of low pressure is associated with the short wave. This will push the high well to the east, allowing for a more unstable atmosphere over South Florida for Thursday, allowing for some slight chance PoPs for much of South Florida on Thursday. Thursday night, a surface trough, ahead of the cold front, develops, and moves into the area. This could potentially keep showers and thunderstorms going through the overnight hours and into early Friday morning. && .Marine... Scattered showers and thunderstorms are expected over the local waters today and remain possible on Sunday. Lightning, strong gusty winds, and waterspouts are possible with these storms. Cautionary to hazardous marine conditions are possible by early next week as winds and seas increase. && .Aviation (18Z TAFS)... Shower/thunderstorm chances increasing for the eastern terminals through 22-23z, then decreasing. Gusty and erratic winds, along with sub-VFR conditions expected if a storm directly impacts a terminal. Outside of this mainly SSW winds, but the near-coast sites could briefly see SSE with the sea breeze just slightly inland at the moment. Rain chances diminish tonight with winds becoming more SSE on Sunday. && .Beach Forecast... There is a moderate risk for rip currents for the Palm Beaches today. Showers and thunderstorms are likely for the Atlantic beaches today with strong winds and lightning possible. && .Preliminary Point Temps/PoPs...
