Synopsis: High pressure will remain over the waters over the next couple of days with light east to southeast winds shifting onshore in the afternoon due to the seabreeze. A cold front will move across the northern waters late Wednesday into Thursday, turning winds to the southwest. Moisture pooling ahead of this front may allow for periods of sea fog, especially over the northern waters and near the Florida Big Bend, though some potential will also exist further south. High pressure will fill in behind the front with light winds and seas 2 feet or less expected into the weekend.
