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 Melbourne, FL wrote its last area forecast discussion before the first event at Aug 17, 8:29 AM EST, 5 hours 1 minute earlier.
Area Forecast Discussion National Weather Service Melbourne FL 929 AM EDT Mon Aug 17 2020 .DISCUSSION... Mostly sunny to partly cloudy skies were observed across east central FL this morning. Local Doppler radars were already indicating storms reaching the western coast of FL but dissipating along the coastal counties. Forecast remains on track as we expect showers and thunderstorms developing this afternoon over the interior. The east coast sea breeze will have a chance to develop and move past I-95. These will combine to produce strong storms that will generate gusty winds, lightning strikes and heavy rain. && .AVIATION... VFR for rest of the morning. Then SHRA/TSRA will develop over west central FL and/or interior and move generally to the northeast. TAFs already have mention of TEMPOs and these will be amended as necessary. && .MARINE... Winds generally from the south to southwest will persist today at 5-10 kt. Storms developing over land will then reach the coastal waters later today and produce gusty winds and localized higher seas. Otherwise, seas 1-3 ft are expected. && .PRELIMINARY POINT TEMPS/POPS...
