Scattered thunderstorms developed after the east and west coast sea breezes collided in western Orange County. Cooler temperatures in the mid to upper atmosphere supported one storm that became severe, which produced large hail and some tree damage.

NWS Melbourne, FL wrote its last area forecast discussion before the first event at Jul 19, 1:09 PM EST, 4 hours earlier.
Area Forecast Discussion National Weather Service Melbourne FL 209 PM EDT Fri Jul 19 2019 .DISCUSSION... Current-Tonight...The WC/EC sea breezes are moving steadily inland this afternoon. Convection across the Treasure Coast and Okeechobee County expected to increase in coverage/intensity northward and further into the interior through the afternoon and early evening where additional boundary collisions will occur. Storm threats remain frequent cloud to ground lightning, gusty winds, torrential downpours leading to nuisance/minor flooding thanks in part to weak steering flow, and perhaps some small hail possible as well. The storm threat will diminish thru the evening over the interior. SChc shra/tsra overnight over the coastal waters with SChc for showers along the Treasure Coast. Will opt for pre-first period wording in afternoon ZFP. Overnight lows generally in the L-M70s and U70s for some coastal sites. Cloud debris to thin thru the night. Winds will become light/variable to calm. Previous Extended Forecast Discussion... Weekend...No notable change in position and strength of Bermuda ridge over the peninsula this weekend will keep a forecast of coastal and inland PoP separation with higher pcpn chcs inland due to mid-late afternoon boundary collisions, with SE-S component steering level winds. PoP chcs about 25 to 30 percent coastal zones and 35 to 45 percent inland. Expect highs in the L-M 90s with heat indices 101-105 inland from the immediate coastline, and overnight lows in the M70s. Next Week...A more promising chc for areawide rains will develop by Tue as weakening of local ridge is indicated due to a notable trough moving into the across the SE states. This wl act to displace the Bermuda ridge south of the forecast area into the latter part of next week. Higher rain chcs begin to develop by Tue and persist through midweek, and this looks to improve the dry conditions, especially along the immediate coast, where many places have not had measurable rainfall in a week. && .AVIATION...A few storms will linger near the coastal terminals through around 20Z before transitioning inland. As the east and west coast sea breezes continue to move inland showers and storms will increase in coverage with main impacts for interior terminals in the 19Z to 00Z/01Z time frame. Convection will gradually wind down from sunset onward with most if not all precipitation over by 02Z this evening. VFR overnight into Saturday morning, but there could be some showers near FPR and SUA by the mid morning hours. && .MARINE...Afternoon-Tonight...Weak pressure gradient continues over the local coastal waters. General onshore flow near the coast and S/SE further over the open Atlc. A degree of variability in wind direction this evening with winds near the coast gradually becoming offshore again and a southerly component over the Gulf Stream. Wind speeds 6-12 kts or even lighter at times for some. SChc remains for showers and lightning storms, especially over the Gulf Stream. Seas 1-2 ft. Previous Extended Marine Forecast Discussion... Weekend...Favorable winds and seas with dominant surface ridge over the marine area. Winds largely 6-12 kts, or less with seas 1-2 ft. Extended...Early next week shows continuation of favorable open water conditions with S-SE winds becoming more southerly, and then developing some offshore component by Wed. Seas averaging 2-3 ft, with 1-2 ft near the coast Tue-Wed. && .PRELIMINARY POINT TEMPS/POPS...
