A late season frontal boundary moved slowly south across north Florida, while south of the boundary strong westerly flow was observed across central Florida. Deep moisture was in place across the area, and with cool temperatures aloft and daytime heating, conditions became favorable for the development of scattered to numerous showers and thunderstorms in the afternoon. Some showers and storms formed across the interior counties early in the afternoon and pushed east towards the coast where a few intensified. One severe thunderstorm produced strong to severe winds along the Brevard County Coast. A second thunderstorm produced strong winds along the St. Lucie County coast.
