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 Jun 6, 9:30 AM EDT, 4 hours 43 minutes earlier.
Area forecast discussion, Jun 6, 9:30 AM EDT, 4 hours 43 minutes before
Area Forecast Discussion National Weather Service Melbourne FL 930 AM EDT Wed Jun 6 2018 .DISCUSSION... Areas of light rain from earlier decaying convection has largely diminished across the I-4 corridor this morning. Mid level S/W trough across north Florida into the NE Gulf of Mexico will combine with a moist airmass across the area (PW values 1.8-1.9") to produce high coverage of showers and storms into the afternoon, with rain chances up to 60-70 percent. Northern areas are already seeing some breaks in the cloud cover this morning. This will allow for plenty of daytime heating and instability for numerous showers and storms to develop along and ahead of the west coast sea breeze. pushing eastward across the area and toward the coast and offshore through late day. Slight cooling of temperatures aloft and lingering dry air in the mid levels will keep a threat for strong to isolated severe storms across the area. Main threats will continue to be strong to locally damaging wind gusts, small hail and frequent lightning strikes from this activity. Greater cloud cover across northern areas should keep highs limited to the mid 80s today, while farther south temperatures should be able to reach the upper 80s to around 90 degrees, especially along the coast. && .AVIATION... Localized IFR/MVFR cigs in stratus will continue into late morning before cigs gradually lift with daytime heating. Also, a few showers and isolated storms may move across northern terminals into late morning. However, best potential for tempo IFR/MVFR conditions due to convection will be into the afternoon as numerous showers and storms develop and push eastward toward the east coast of Florida and offshore through late day/early evening. Isolated gusts to 35-45 knots possible in any stronger storms. && .MARINE...Main marine concern today will continue to be offshore moving showers and storms into the afternoon producing strong gusty winds. Otherwise, offshore flow will be at or below 10 knots with seas around 1-2 feet. && .PRELIMINARY POINT TEMPS/POPS... DAB 84 71 87 70 / 70 50 50 30 MCO 87 71 90 72 / 70 40 60 40 MLB 89 72 87 71 / 60 40 60 40 VRB 89 70 87 71 / 70 40 60 40 LEE 85 72 90 73 / 70 50 50 30 SFB 87 72 90 72 / 70 40 60 30 ORL 87 72 90 73 / 70 40 60 30 FPR 90 71 88 70 / 70 40 60 40 && .MLB WATCHES/WARNINGS/ADVISORIES...

Increasing moisture ahead of a stalled frontal boundary, coupled with westerly winds will produce numerous showers and lightning storms across east central Florida today. From early afternoon onward, expect storm coverage to increase farther south and inland, along and ahead of the west coast sea breeze. There is potential for the east coast sea breeze to develop along the immediate coast, with a late afternoon collision possible. Today's storms will move east at 20 to 25 MPH, and will be capable of producing strong win gusts in excess of 40 MPH, small hail, and torrential rainfall of 1 to 3 inches in a 60 to 90 minute period. Move indoors to safety if skies look threatening, or you hear thunder. .MARINE THUNDERSTORM GUST IMPACT... Storms will have the potential to produce wind gusts of 35 knots or greater, small hail and frequent cloud to water lightning today over inland lakes, and especially near the coast, and over the intracoastal and near shore Atlantic waters. Boaters should be on the lookout for storms approaching rapidly from the west, and move to safe harbor in advance of deteriorating weather. .DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY.
