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 Jun 7, 2:12 PM EST, 1 hour 47 minutes earlier.
Area Forecast Discussion National Weather Service Melbourne FL 312 PM EDT Wed Jun 7 2023 ...New DISCUSSION, MARINE, AVIATION, HYDROLOGY... .DISCUSSION... Issued at 310 PM EDT Wed Jun 7 2023 ...A Few Strong to Marginally Severe Storms Possible Through Late Afternoon and Early Evening... Currently-Tonight...Had a little earlier start to convection across northern portions of east central FL, with additional isolated to scattered showers and storms moving E/NE through the area ahead of the west coast sea breeze. The east coast sea breeze has formed near to south of the Cape, and will struggle to make it too far inland with opposing low level SW flow. An increase in showers and storms, with a few strong to marginally severe storms still expected through remainder of the afternoon, especially toward the coast with sea breeze boundary interactions later today. Main threats continue to be strong to locally damaging wind gusts of 40-60 mph, hail up to an inch in diameter, frequent lightning strikes, and heavy rainfall of 1-3 inches. A brief tornado also can not be ruled out along the coast as storms push offshore. This activity will largely shift offshore by early this evening, with decreasing rain chances through tonight. Lows tonight will fall into the upper 60s to low 70s. Thursday-Friday...Subtropical ridge axis remains south of the area, as a frontal boundary shifts into the southeast U.S. into late week. This will continue a moderate offshore flow through the period. Model guidance hints that offshore flow may be a tad stronger into tomorrow, which may prevent east coast sea breeze development completely, with W/SW flow decreasing once again into Friday as front moves closer to the area. PW values generally range from 1.6- 1.8 inches across the area between the GFS which is a little drier then the ECMWF. This will still be sufficient, combined with the offshore flow, to focus scattered showers and storms across east central FL into the afternoon and early evening, with stronger to isolated severe storms possible, especially into Friday toward the coast with any sea breeze boundary interactions. Highs reaching the upper 80s to low 90s. Muggy and mild mornings are forecast with temperatures to start each day in the upper 60s to low 70s. Saturday-Tuesday...(Previous Discussion) A surface front briefly stalls across east central Florida Saturday morning before more quickly lifting north Saturday afternoon and night as a warm front. Weak and variable surface flow will be conflated by a more organized east coast sea breeze. A collision of the west and east coast breezes is expected moreso over the interior Saturday, and with sufficient PW of 1.6 to 1.8 inches, more scattered convection is forecast for Saturday afternoon. Copy and paste for Sunday, plus a resumption of light southerly flow, with similar daytime thunderstorm chances around 40 to 50 percent. Mid level trough axis energy swings across the state Monday, providing some additional lift for convective development. Both Monday and Tuesday will see an increase in southwest flow, leading to sea breeze collisions and perhaps slightly higher rain chances closer to the Atlantic coast. Temperatures this weekend into next week really heat up. Highs from Sunday onward will range through the low 90s, with models hinting at a chance to solidly reach the mid 90s midweek next week. Morning lows will remain mild, warming into the mid 70s for some locations next week. && .MARINE... Issued at 310 PM EDT Wed Jun 7 2023 Tonight...Main concern to boaters will continue to be scattered to potentially numerous offshore moving storms through the remainder of the afternoon into early this evening. A few strong to isolated severe storms will be possible, producing gusty winds, frequent lighting strikes, hail, and possible a waterspout or two. This activity will continue to push farther offshore through late evening and likely east of the coastal waters overnight. Otherwise, S/SE winds become SW into this evening and W/SW overnight with winds increasing up to 10-15 knots. Seas 2-3 feet. Thursday-Sunday...(Previous Discussion) Offshore flow is expected through much of the period with daily attempts at developing an east coast sea breeze. Development may be suppressed or held to the east coast with a more active west coast breeze anticipated, at least through Friday. Winds speeds 10-15 kts, closer to 17 kts far offshore. Surface flow becomes more variable Saturday in the presence of a weak frontal boundary, which quickly lifts back north as a warm front into Sunday, allowing for a return to southerly flow. Seas generally 2-3 ft with briefly higher seas in or around lightning storms. Isolated to scattered lightning storm chances will persist through this forecast period, generally maximized from mid afternoon through the evening hours. && .AVIATION... (18Z TAFS) Issued at 310 PM EDT Wed Jun 7 2023 VCTS conditions across ECFL this afternoon and into tonight, with increasing coverage of showers and storms expected over the next several hours. TEMPOs in place for VIS/CIG reductions down to MVFR/IFR conditions due to TSRA at all terminals, generally between 18-23Z. Conditions improving after 02Z across all terminals, with SW winds around 5 knots. Tomorrow, winds pick up around 13Z out of the SW near 10 knots, with VCTS starting up again as early as 17Z. && .HYDROLOGY... Issued at 310 PM EDT Wed Jun 7 2023 The river level at Astor on the Saint Johns River has fallen below Minor Flood stage and will continue a slow decline through Action Stage through Thursday night. River levels should then fall below Action Stage by late week. && .PRELIMINARY POINT TEMPS/POPS...

Daytime heating, an increase in moisture, and an active west coast sea breeze will promote scattered lightning storms across the interior this afternoon. The east coast sea breeze will develop this afternoon, but inland movement will be minimal due to a greater depth of offshore flow. An increase in coverage and intensity of showers and storms will occur later this afternoon and early evening with the larger sea breeze collision across the eastern peninsula and additional mesoscale outflow boundary interactions. Storm motion will be toward the east or northeast at 15 to 20 mph. A few storms could become strong to marginally severe. Primary storm threats include occasional to frequent lightning strikes, gusty winds of 40 to 55 mph, with one or two storms potentially up to 60 mph, small hail up to possibly quarter-size, and torrential downpours. A brief tornado may occur from developing storms near the coast late in the afternoon and early evening as they move off of the coast. .RIP CURRENT IMPACT... A Moderate risk of life-threatening rip currents exists at all central Florida Atlantic beaches today. If heading to the beach, check with local beach patrol for additional information about ocean hazards. Remember to swim only within sight of a lifeguard, and never enter the ocean alone. .MARINE THUNDERSTORM GUST IMPACT... Isolated to scattered afternoon and evening lightning storms may produce wind gusts up to 35 knots over the local Atlantic waters and Intracoastal Waterway, including over inland lakes. Storm motion will be toward the east to northeast at 15 to 20 knots. .WATERSPOUT IMPACT... Marine interests should also be alert for the potential of waterspouts late today and this evening, especially near the coast and across the near shore Atlantic waters. .RIVER FLOOD IMPACT... The river level at Astor on the Saint Johns River has fallen below Minor Flood stage and will continue a slow decline through Action Stage through Thursday night. River levels should then fall below Action Stage by late week. .DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY. Coverage of lightning storms will continue to increase into Thursday and Friday, with continuation of scattered coverage into the weekend and early next week. A few strong to isolated severe storms will remain possible. Lightning strikes, gusty winds, and heavy downpours will continue to be the main threats. A Moderate risk of dangerous rip currents is expected to continue through the rest of the work-week. .SPOTTER INFORMATION STATEMENT... Spotters should monitor the weather and self activate if needed.

2 thunderstorm wind, 1 tornado. Local standard time, as filed.
The Cape Canaveral Space Force Station Skid Strip KXMR ASOS measured a 53 knot wind gust from the west-northwest.
A National Weather Service Melbourne damage survey confirms that an EF-1 tornado impacted the South Patrick Shores community just south of Patrick Space Force Base. The tornado touched down initially in the Lighthouse Landing subdivision near the intersection of Lighthouse Landing St. and South Patrick Dr. The circulation continued on an east-northeast trajectory across the South Patrick Shores community before emerging into the Atlantic near Ocean Blvd. and SR A1A. The tornado was on the ground for approximately 1.0 mile, had a maximum width of approximately 300 yards, and peak winds estimated between 90-100 mph.
Brevard County Emergency Management conducted a damage assessment and noted numerous homes were affected with at least some damage, 25 homes with minor damage, and 10 with major damage. NWS meteorologists documented impacts on both the north and south sides of the tornadic circulation in an area bounded by SE 1st St. to the south and NE 2nd St. to the north. Numerous homes in this area experienced at least partial losses of their carports and awnings. Additionally, several homes lost portions of their roof, a few trees were uprooted, and between 6-10 power poles were snapped in this area.
The Leesburg International Airport ASOS measured a 50 knot wind gust from the southwest.
