The episode as NWS MLB wrote it up.
A weak cold front located across north central Florida moved slowly south into east-central Florida during the day. Increasing wind shear, strong daytime heating, ample moisture and cold temperatures in the middle atmosphere led to the development of numerous strong thunderstorms across the Florida peninsula. West to southwest winds pushed these storms towards the east coast. One thunderstorm developed in northeastern Palm Beach County and quickly became severe as it crossed into southeastern Martin County. There the storm produced wind damage, mainly at Jonathan Dickinson Park.

Be on the lookout for storms approaching rapidly from the west today. Move indoors for safety away from windows if skies begin to look threatening, or if you hear thunder. .MARINE THUNDERSTORM GUST IMPACT... There is a high likelihood for at least a few of today's storms to produce wind gusts of 35 knots or greater and frequent lightning strikes on area lakes, as well as the Intracoastal Waterway and adjacent Atlantic waters. .DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY. Scattered to numerous showers and lightning storms are expected again on Tuesday, with slightly higher chances from Lake Kissimmee and Melbourne south to Lake Okeechobee and Tequesta.
