The episode as NWS MLB wrote it up.
Central Florida was sandwiched between the Atlantic ridge to the south and a weak low pressure system to the north. This continued the pattern of southwest winds and deep moisture across the Florida peninsula. In the middle atmosphere, a weather system was moving across the eastern U.S. and that provided enough energy to create an unstable atmosphere capable of producing severe thunderstorms. With plenty of daytime heating, showers and thunderstorms developed along the west coast sea breeze in the morning and pushed across the peninsula through the afternoon. As one storm moved over the Orlando Metro area it became severe and produced a wind gust over 60 mph. Later in the afternoon, another thunderstorm became severe as it moved across central Brevard County where two reports of winds over 60 mph were received from Merritt Island.

Area Forecast Discussion National Weather Service Melbourne FL 1012 AM EDT Wed Jun 12 2019 .UPDATE... The synoptic setup has east central Florida in between Atlantic high pressure ridge and low pressure trough extending from the Great Lakes into the northern Gulf of Mexico. This has the area in a fairly deep layer of southwesterly flow and will provide another day of west coast breeze dominant convection. This morning's satellite- derived precipitable water (PWAT) shows 1.7" to 1.8" NW of the I-4 corridor to slightly lesser values of 1.6" to 1.7" south and east, supporting scattered to numerous showers and storms this afternoon, some of them becoming strong. A few showers and storms were already being observed along the western side of the peninsula as of 10 am, and this activity could push into Lake county as early as 11 am. However, the main timing window for showers/storms across interior locations and Volusia county will be similar to yesterday being the early to mid afternoon hours and mid afternoon to early evening closer to the coast. Also similar to yesterday, will keep mention of a chance of storms into the evening hours as a few mesoscale models are showing some redevelopment. Gusty winds of 40-50 mph will be possible within stronger convection today along with frequent lightning. Torrential downpours are also possible, but quicker storm motion of 20 to 25 mph should keep any flood threat minimal. && .AVIATION... VFR conditions outside of showers and storms. Highest shower/storm chances will spread from west to east again today initially near the interior terminals and DAB from early to mid afternoon and then the coastal terminals from TIX-SUA from mid afternoon into early evening. Showers/storms will be capable of IFR visibilities and also wind gust of 35-40 kts in the stronger storms. Some redevelopment of showers and storms is possible during the evening so will keep mention of VCSH through 00-01Z but may need to put in VCTS later on. && .MARINE... Previous forecast in good shape with no changes required for this morning's update. Today-Tonight (previous)...A gentle to moderate south-southwest breeze will persist for the next day or so. Current data from buoys across the area show seas are around 1-2 feet, thus have capped the forecast for seas at 2 feet for much of the waters with perhaps some 3 foot seas well offshore the Volusia/Space Coast late tonight. Expecting another round of showers and storms this afternoon and evening, with the main threats being dangerous cloud to ground lightning strikes and wind gusts to 35 knots. && .PRELIMINARY POINT TEMPS/POPS...

Scattered to numerous showers and lightning storms are expected this afternoon and evening across east central Florida, some of them strong with an isolated severe storm possible. The Storm Prediction Center has placed areas from Kissimmee to Titusville northward in a marginal risk of severe weather. By noon through the early afternoon, expect an increase in coverage and intensity of storms as they approach the I-4 corridor and also across interior locations south of I-4 with showers and storms reaching the coast by mid to late afternoon. Frequent and deadly cloud to ground lightning strikes will be the main hazard with all thunderstorms that develop. Additionally, wind gusts to 40-50 mph will be possible with strong storms and up to 60 mph in a severe storm. If you hear thunder in the distance or see lighting, seek shelter in a sturdy building. Remember: When Thunder Roars, Go Indoors! .FLOOD IMPACT... Some storms may produce torrential downpours, with amounts ranging from 1 to 2 inches over a 1 to 2 hour period at some locations. The locally heavy rainfall of the past several days has increased the threat for temporary flooding of urban, low lying, and poorly drained areas, especially across Lake, Volusia, Seminole, Orange, and northern Brevard Counties. Don't drive where water covers the road. the depth may be too great to allow your vehicle to pass safely. .MARINE THUNDERSTORM GUST IMPACT... Scattered to numerous storms will move over the nearshore Atlantic waters, including the Intracoastal and also over inland lakes. Some strong storms could produce wind gusts in excess of 35 knots this afternoon and evening. Mariners should keep an eye on the sky and watch for approaching storms from the southwest later today. .DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY. Scattered to numerous showers and lightning storms are expected across east central through this weekend. The heaviest rain and strongest storms will briefly shift to the western side of the peninsula Saturday, but should begin to shift back eastward once again early next week. The main concerns will continue to be deadly cloud to ground lightning strikes, and an increasing threat of poor drainage flooding. Locally gusty winds will also be possible. .SPOTTER INFORMATION STATEMENT... Spotters are requested to monitor the weather and self activate if needed. Please report any rainfall amounts of 2 to 3 inches or more, or flooding of roads or property to the National Weather Service in Melbourne. Combs/Rodriguez
