A weak cold front entering the southeastern states will nudge southward today, crossing the Georgia waters tonight and then becoming stationary over the northeast Florida waters by Friday evening before dissolving during the weekend. Meanwhile, strong high pressure building over the eastern Great Lakes in the wake of this cold front will shift eastward over New England on Friday, with this feature then wedging down the southeastern seaboard from Friday afternoon through early Sunday. Onshore winds will strengthen beginning on Friday afternoon, with speeds and seas likely reaching Small Craft Advisory levels from early Saturday evening through at least Sunday morning for the offshore waters adjacent to northeast Florida, while Caution conditions are forecast for the near shore waters adjacent to northeast Florida. High pressure will then gradually weaken as it shifts southward late this weekend, with this feature then becoming anchored off the Carolina coast by early next week. Onshore winds and seas will gradually diminish throughout our local waters late this weekend and early next week. .GULF STREAM...
