A weak surface trough moved south along the east coast of Florida, which kept light surface winds across central Florida. The east and west coast sea breezes developed, with the west coast sea breeze dominating. Initially showers and thunderstorms developed along the collision of the sea breezes across eastern Orange County south through Lake Okeechobee. Then, additional storms formed along the collision of numerous outflow boundaries produced by the first round of storms. Eventually, the storms merged into a line that pushed towards the Brevard County coast. There, one storm produced strong winds along the intracoastal waters in north Brevard County.

The main flow across central Florida was from the west-southwest due to a frontal trough moving across the mid-Atlantic states, and the axis of the Bermuda High Pressure situated across south Florida. Moisture was high across the area with Precipitable Water values around 1.80 to 2.00 inches. Temperatures aloft at 500 mb were around -6 to -7 degrees Celsius. The atmosphere was favorable for showers and thunderstorms to develop along the east and west coast sea breezes. Due to the stronger west winds, the west coast sea breeze was dominant, and the main collision between the two sea breezes occurred closer to the east central Florida coast. After storms developed, they pushed towards the Brevard Coast where one storm produced a strong wind gust along the intracoastal waters.
