The local office's own words before this special weather statement went out, 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 this special weather statement went out at Jul 18, 9:24 AM EDT, 4 hours 31 minutes earlier.
Area forecast discussion, Jul 18, 9:24 AM EDT, 4 hours 31 minutes before
East Central Florida Forecast Discussion National Weather Service Melbourne FL 924 AM EDT MON JUL 18 2016 .DISCUSSION... A deep layer onshore flow pattern will continue early this week with lower than average precipitable water than one would expect in this regime, especially over the next 24H. The main feature is an apchg upper TUTT presently moving across the FL Straits toward ECFL. Mid level drying evident on ltst WV imagery will overspread the forecast area during the remainder of the day and this combined with a rapidly onshore moving sea breeze boundary will largely eliminate the coastal zones from measurable pcpn chcs. The current forecast is in good shape, reserving the interior zones for iso-sct showers and some thunderstorm potential from early through mid afternoon. Isolated showers over the marine area will potentially move through the hostile sea breeze circulation zone and bring a sprinkle or two to locations mainly south of Cape Canaveral. Little change in high temperatures is indicated with mid 90s inland and around 90 at the coast. && .Climate...Melbourne's low temperature this morning was only 83 degrees. If this holds through 1 AM tonight it will equal the all- time warm minimum for any date. && .AVIATION...Isolated Atlantic showers will cross the coast mainly S of KCOF very brief and localized MVFR. Coverage is too low for any tempo mention. The same goes for interior terminals where small shower/storm chances exist mainly in the mid-late afternoon. && .MARINE... Today-Tonight...(prev disc) High pressure ridge axis to our north will produce an easterly wind flow. Speeds look to be 5-10 knots north and 10-15 knots south. Seas will be 2-3 feet and up to 4 feet well offshore. Westward moving showers or storms will continue to have a low coverage. && .MLB Watches/Warnings/Advisories... FL...None. AM...None. && JP/WU
