The episode as NWS MLB wrote it up.
An area of low pressure and a weak cold front moved across central Florida sparking numerous showers and thunderstorms across the area. Deep moisture was in place across the area, and instability had increased through the day due to daytime heating. The instability, combined with lift associated with the approaching cold front and cold temperatures in the middle part of the atmosphere, allowed a few thunderstorms to become severe. In Volusia County, a strong storm produced nickel sized hail. In Seminole County, damaging winds caused numerous trees to be uprooted. In Brevard County, a severe thunderstorm produced a strong wind gust at the Cape.

NWS Melbourne, FL wrote its last area forecast discussion before the first event at Apr 9, 9:25 AM EST, 5 hours earlier.
Area Forecast Discussion National Weather Service Melbourne FL 1025 AM EDT Tue Apr 9 2019 .DISCUSSION... The Atlc hi pres ridge has retreated into the NW Carib ahead of a weak storm system advancing thru the Deep South. The attending H100- H70 frontal trof extends to the Yucatan Peninsula and will advance toward the SErn seaboard today under the influence of an 80-100KT H30-H20 jet streak lifting acrs the Carolinas and the FL Big Bend region. The 09/12Z RAOBs showed enhanced instability aloft over central/south FL with CAPE values generally btwn 1500-2000 J/KG.

H50 temps btwn -10C/-11C, while mid lvl omega/upr lvl div fields show moderate to strong dynamic support. Mid lvls are moderately unstable as well with H85-H50 lapse rates running btwn 6.0-6.5C/KM. Biggest inhibitor of the day will be sfc heating as dense cloud cover suppresses temps. Sat imagery does show some clearing over the west central peninsula and ern GOMex, but so far clouds have been slow to clear over east central/south FL. S/SW flow overhead will allow temps to warm quickly once the clouds clear...both the 6KM WRF/HRRR models indicate this happening by early aftn.

Scattered lightning storms are forecast to move quickly eastward across east central Florida and offshore during the afternoon and early evening hours. A few stronger storms may occur, with the main threats being frequent lightning strikes, strong wind gusts up to 40 to 50 mph and small hail. Any areas that experience multiple rounds of heavy precipitation could see localized heavy rainfall. This may cause minor ponding of water on roadways and poor drainage areas. .MARINE THUNDERSTORM GUST IMPACT... Scattered lightning storms moving quickly eastward around 25 to 35 knots will have the potential to produce wind gusts in excess of 34 knots across inland lakes, and as they push offshore the east central Florida coast through the afternoon and early evening hours. .WIND AND SEA IMPACT... South to southwest winds of 15 to 20 knots will occur over the open Atlantic into tonight. Small craft should exercise caution if venturing offshore into the evening and overnight hours for these poor boating conditions. .DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY. An elevated risk of rip currents will continue along the beaches of east central Florida through the remainder of this week. .SPOTTER INFORMATION STATEMENT... Spotters are requested to monitor the weather and self activate if needed. Pendergrast
