Strong high pressure centered over the Ohio Valley and the eastern Great Lakes will continue to wedge down the southeastern seaboard, creating strong northeasterly winds through the weekend and early portions of next week. Meanwhile, coastal troughing taking shape over the near shore waters adjacent to northeast Florida will generate occasional showers beginning this afternoon and continuing through early next week. Small Craft Advisory conditions will remain ongoing offshore, with a surge in wind speeds late this afternoon and evening bringing Small Craft Advisory conditions to the near shore waters. Seas are expected to build to Small Craft Advisory levels near shore beginning on Saturday night, with elevated winds and seas expected near shore through Monday. High pressure will then weaken as it settles southward on Tuesday and Wednesday, allowing for winds and seas to gradually subside. .GULF STREAM...
