Synopsis: Atlantic high pressure will remain positioned just south of the northeast Florida waters through Tuesday. A cold front will approach the Georgia waters from the northwest by late Wednesday, and winds could reach caution levels with the front. This front will then stall near the Georgia and Florida border late this week while dissipating. High pressure building over the Middle Atlantic and New England late this week will wedge down the U.S. eastern seaboard, resulting in light onshore winds developing by late Thursday.
