AMZ400-141045- Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm- 223 PM EST Thu Feb 13 2025 .SYNOPSIS... A cold front will cross our local waters late this afternoon and early this evening, accompanied by showers and a few embedded thunderstorms. Winds will shift to northerly later this evening as strong high pressure builds eastward towards the Ohio and Tennessee Valleys. Northerly winds will then strengthen overnight, resulting in Small Craft Advisory conditions developing throughout our local waters during the predawn hours. Strong high pressure will then progress eastward towards the Mid-Atlantic coast by Friday evening, with this feature briefly wedging down the southeastern seaboard on Friday, creating strong northeasterly winds that will continue into the early evening hours, with occasional gusts to Gale Force possible offshore. Winds will shift to easterly during the overnight hours and then southeasterly by Saturday morning as high pressure shifts off the Mid-Atlantic coast. This weather pattern will allow a warm front to lift northward from the Florida peninsula, with showers developing on Saturday and Saturday evening as this boundary lifts northward. Elevated seas will keep Small Craft Advisory conditions in place offshore this weekend, while Advisory level seas near shore continue through Saturday afternoon. Meanwhile, low pressure developing over the lower Mississippi Valley on Saturday afternoon will strengthen as it accelerates northeastward across the Tennessee Valley and the southern Appalachians, with this storm system's cold front approaching our local waters on Sunday afternoon. Southerly winds will gradually strengthen on Saturday night and will shift to southwesterly on Sunday, with Small Craft Advisory conditions redeveloping near shore. Showers and a few embedded thunderstorms will cross our area on Sunday afternoon and evening, followed by winds shifting to northwesterly in the wake of the frontal passage before midnight. Arctic high pressure will then spill into the Plains states early next week, with strong northerly winds keeping Small Craft Advisory conditions in place for the offshore waters through at least Monday afternoon. .GULF STREAM...
