The episode as NWS MFL wrote it up.
Nearly stationary upper level troughing over the region helped keep deep moisture in place to produce widespread convection. Strong thunderstorms developed along the pinned east coast sea breeze. One thunderstorm produced a wind gust that knocked down a power line in Broward 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 Aug 3, 3:12 PM EST, 7 minutes earlier.
Area Forecast Discussion National Weather Service Miami FL 412 PM EDT Sat Aug 3 2019 ...COASTAL FLOOD STATEMENT IN EFFECT FOR THE EAST COAST BEACHES OF SOUTH FLORIDA THROUGH 0400 AM SUNDAY MORNING... ...HEAVY RAINFALL IS STILL POSSIBLE OVER SOUTH FLORIDA REST OF THIS WEEKEND INTO EARLY NEXT WEEK... .DISCUSSION... TONIGHT AND SUNDAY... A mid to upper level trough of low pressure will remain nearly stationary over the Eastern Gulf of Mexico tonight and Sunday as high pressure remains over the Central Atlantic Waters. At the same time, a low level trough over the Bahamas will be moving west northwest towards South Florida tonight and into South Florida on Sunday. This weather pattern will keep the south/southwest steering flow in place along with the deeper tropical moisture over South Florida. Therefore, scattered to numerous showers and thunderstorms should develop over the region on Sunday first affecting the west coast metro areas in the morning then affecting the interior and east coast metro areas in the afternoon and evening hours. The PWAT values will also remain in the 2 to 2.2 inch range on Sunday which is in the 90th percentile range for this time of year leading to possible heavy rainfall with the thunderstorms. More on this in the hydro section below. EARLY NEXT WEEK... The mid to upper level trough of low pressure will slowly shift to the northeast from the Eastern Gulf of Mexico into the Southeastern United States as the low level trough moves northward into Central Florida from South Florida. This will allow for the steering flow over the region to slowly shift from the south/southwest direction on Monday to more of a southerly direction on Tuesday and Wednesday focusing the best coverage of shower and thunderstorm activity from the eastern areas on Monday to more around the Lake Okeechobee region by Tuesday into Wednesday. However, the deeper tropical moisture will still remain in place over South Florida for early next week with the PWAT values around 2 inches which is still around the 90th percentile for this time of year. This will still lead to some heavy rainfall over the region each day. EXTENDED FORECAST... High pressure over the Atlantic waters should slowly build back westward late this week into next weekend, as the mid to upper level trough continues to move slowly northeast away from the region. This will allow for the steering flow to be more south/southeast over South Florida focusing the best coverage of showers and thunderstorms over the interior and Lake Okeechobee region. However, scattered showers and thunderstorms are still possible over the metro areas for late next week into next weekend. && .MARINE... The wind flow will remain in a south/southwest direction tonight through Monday before swinging to more of a southerly direction for middle of next week. The wind speeds will remain at 15 knots or less over all of South Florida waters through middle of next week. The seas will remain at 2 feet or less in both the Atlantic and Gulf waters of South Florida rest of this weekend into early to middle of next week. && .AVIATION... Scattered to numerous SHRA/TSRA are organizing along the eastern terminals. Storm outflow interaction and cell training will extend periods of MVFR/IFR through most of the afternoon. Brief downpours may drop visibilities between 1/2SM - 1SM, and wind gusts up to 30-35kts are possible, particularly at the northern terminals. Winds will be mostly out of the S/SE, with a VRB shift overnight around 01-03Z. && .BEACH FORECAST... The Coastal Flood Statement has been extended for the east coast beaches of South Florida through 0400 AM Sunday morning as there is still about half a foot to one foot above normal water levels being reported from the high tide this morning. These higher water levels will still take some time to come down and there could still be some minor street flooding and dock flooding from the higher water levels at the next high tide late this evening. && .HYDROLOGY... The combination of widespread rainfall and above normal tides will continue to bring the potential for localized flooding and/or minor coastal flooding tonight into Sunday. At this time, total rainfall accumulation of up to 1 inch over the west coast of South Florida to 1 to 3 inches over the eastern half of South Florida will be possible through Sunday with localize higher amounts. The latest short range models are also showing that there could be some training of showers and thunderstorms over some areas of South Florida through at least Sunday evening. If a training convective pattern were to become established, then a localized flooding potential could materialize. At this time, the confidence is too low to have a flood watch for the area, but if confidence were to increase then a flood watch may be needed in later forecast packages. The excessive rainfall risk should continue over South Florida through at least Sunday. A Hydrologic Outlook (ESFMFL) provides more detail regarding potential flooding threats over south Florida. && .PRELIMINARY POINT TEMPS/POPS...
