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 28, 3:00 PM EST, 2 hours 36 minutes earlier.
Area Forecast Discussion National Weather Service Miami FL 400 PM EDT Thu Jun 28 2018 .DISCUSSION... Latest WPC analysis shows a thermal trough over the peninsula. With light flow in place, this feature will continue to allow a light sea breeze to penetrate inland a couple miles. Satellite derived PWAT currently depicts values near 2.1" over a majority of our CWA, indicating a high moisture content, even for early summer in Florida. Mostly sunny skies have led to strong diurnal heating, destabilizing the atmosphere. These factors will help to maintain scattered thunderstorms activity into this evening, which should slowly drift southward, pushed by light northerly flow in the mid levels. Although highest storm coverage is expected to be over the interior, isolated coverage may develop elsewhere. This slow moving convection could produce training cells with heavy rain, leading to minor flooding and ponding of water on the roads. This mornings MFL RAOB sounding indicated CAPE values well above 2000 J/KG, which was even higher when modified. Thus, strong up and down drafts could allow for small hail to reach the ground and gusty erratic winds associated with this activity. Short term models prog these showers and storms to diminish by around 8pm, becoming isolated, with the loss of diurnal heating. Friday into this weekend: On Friday, surface high pressure near Bermuda begins to become more dominant, with its influence pushing further west towards the Florida peninsula. However, light flow remain in place with forecast PWAT values again above 2.0". Thus, expecting similar coverage of PoPs, when compared to today, with scattered showers and thunderstorms developing areawide by Friday afternoon. Maximum temperatures will be in the low 90s, typical for this time of year. By early Saturday, southeast flow becomes more established, along with a SAL layer advecting over South Florida. This layer may act to slightly dry and stabilize the atmosphere, leading to less convection. None the less, enough moisture will still exist for showers and storms to develop over the interior in the early afternoon and push towards the northwest, away from the east coast metro. Heat index values in the 100-105 range are likely over Collier County and portions of southwest Florida. Early next week: On Monday, east to southeast low-level flow will continue, quite similar to the weekend weather under the influence of weak low- level ridging. Moisture is likely to gradually increase to near normal levels for this time of year Tuesday and beyond with southeast or easterly flow. && .MARINE... Weak high pressure over the region will continue to create light and variable winds through through the rest of this afternoon with seas less than 2 feet across the Atlantic and Gulf waters. A southeasterly wind flow will then prevail on Friday afternoon through the upcoming weekend with seas around 2 feet. Scattered showers and thunderstorms are possible each day. Locally higher winds and seas will be possible in and around and showers or thunderstorms. && .AVIATION... SHRA/TSRA developing on seabreezes currently, with coverage picking up through remainder of afternoon. Prevailing light NW flow likely to keep east coast seabreeze near TAF sites, so have kept VCTS for all sites through 00Z with tempo conditions as satellite shows increasing cloud development. Gusts up to 30kts possible near any convection. Debris SHRA may linger along east coast sites through 02Z-03Z, then VFR with light/vrb winds overnight. Similar conditions again on Fri, though coverage may be a little lower. && .PRELIMINARY POINT TEMPS/POPS...
