Detailed Forecast


Synopsis: High pressure will be east northeast of region through Saturday. With warm air passing over the cooler western Atlantic waters, patchy to areas of sea fog are expected through Saturday, especially across the Georgia near shore waters. A cold front will cross area waters from the northwest late Sunday with a round of showers expected. High pressure will build to the northwest behind this front into Monday, and to the northeast Tuesday. A period of advisory criteria conditions are expected Sunday night into Monday, due to enhanced pressure gradient between departing cold front and building high. As the high moves more to the east, areas of low pressure will track east across region late Wednesday through Friday with scattered showers and possible thunderstorms
