This low pressure center will then move across the southeast Georgia waters on Friday evening, pushing a cold front and showers into our region. This cold front will move south of our local waters by early Saturday, with winds becoming onshore by Saturday evening as high pressure shifts southeastward from the Upper Midwest into the Ohio Valley. High pressure will then wedge down the southeastern seaboard as it weakens on Sunday, and a warm front will then lift northward from the Florida peninsula by Sunday night. .GULF STREAM...
