The episode as NWS MFL wrote it up.
A warm and moist S to SW wind flow combined with low pressure aloft over the SE United States led to the development of afternoon showers and thunderstorms across SE Florida, some of which were severe over Miami-Dade County.
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 19, 11:37 AM EST, 1 hour 23 minutes earlier.
Area Forecast Discussion National Weather Service Miami FL 1237 PM EDT Mon Jun 19 2023 ...New SHORT TERM, AVIATION, MARINE... .SHORT TERM... (Rest of today through Tuesday) Issued at 1232 PM EDT Mon Jun 19 2023 Showers and thunderstorms dominate the sensible weather across South Florida for the next couple of days. Deep mid to upper level troughing remains dominant across the eastern CONUS. A deep upper level trough is pushing away from the Northeast states while an additional upper low is deepening and pushing towards the Southeast this afternoon. As a result, surface flow across South Florida remains west to southwest through the period, keeping abundant moisture through the boundary layer. Shower and thunderstorm development is likely once again later this afternoon as the sea breezes push inland. Convective initiation will likely occur across the Everglades and push to the east-southeast through the evening hours. With more of a westerly component to the winds today, a greater concentration of showers and storms over the metro areas is expected. With PWATs of about 2 inches, ample moisture is in place for any slow-moving or training activity to cause localized flooding issues across portions of the eastern metro areas. A few of these storms may become strong to severe with damaging wind gusts being the primary hazard in any stronger activity that develops. Tuesday is an almost identical forecast to today. Surface flow remains southwesterly with a round of isolated to scattered showers and thunderstorms expected to develop in the mid-afternoon hours. A mid-level dry air intrusion may be able to limit coverage for the afternoon hours tomorrow although there should still be enough moisture and instability for at least a few thunderstorms. High temperatures will be in the lower 90s today and tomorrow with heat indices pushing into the lower 100s. && .LONG TERM... (Tuesday night through Sunday) Issued at 305 AM EDT Mon Jun 19 2023 A continued plume of tropical moisture and a stalled surface frontal boundary to the north of our region will keep elevated rain chances across our area during the remainder of the work week. From a synoptic standpoint, the primary feature of influence will be a cut- off low meandering over the northern GOM region, which may finally lift north-northeast by the end of the period. However, as mentioned in previous discussions the predictability of such a pattern is low. This is highlighted by the fact that the current consensus evolution, i.e. the low opening up and lifting N-NE late week, was not the consensus solution only a couple model cycles ago. As the low lifts out, ridging from the western Atlantic will build towards the area late in the week. However, strengthening southerly-southwesterly flow aloft between the ridge and departing low may funnel additional moisture into the area late week into this weekend. Overall, Wednesday is looking qualitatively similar to Tuesday although some slight westward progression of the low may focus the best rain chances slightly further north than Tuesday. Forecast uncertainty wanes in the Thursday-Saturday period, as much will depend upon the cut-off low`s evolution as well as the potential tropical moisture surge into the area. Above normal precipitation chances look probable regardless of solution, but the amount of rainfall will be dependent upon exactly where the slug of deep moisture orients itself. Regardless, generally higher moisture will result in greater cloud cover which will bring temps/heat indices closer to seasonal normals. && .AVIATION... (18Z TAFS) Issued at 1232 PM EDT Mon Jun 19 2023 VFR conditions will prevail through the period with west-southwest winds across all sites. TEMPOs for thunderstorms for eastern sites through 23Z. Short fuse amendments may be necessary as convection develops later this afternoon. L/V winds and dry conditions expected overnight. && .MARINE... Issued at 1232 PM EDT Mon Jun 19 2023 A generally moderate to robust south to southwesterly flow is expected to continue across the Atlantic marine zones and the Gulf waters through the majority of the week. Expect seas mainly around 2 feet or less over the Gulf waters and 3 feet or less over the Atlantic waters. Scattered to numerous showers and thunderstorms will be possible each day. Any thunderstorms that form could produce brief periods of rough seas and gusty winds. && .PRELIMINARY POINT TEMPS/POPS...
