&& .MARINE... Latest sfc analysis shows a cold front over the OH Valley with high pressure centered well offshore. The front crosses the area late tonight into Monday morning. Previous headlines remain in the place over the next couple days, with winds/waves/seas ramping up tonight as the pressure gradient increases just ahead of the front, then further into Mon/Mon night with another CAA surge. Expect 15-25 kt winds over the Bay/Sound/Lwr James with waves over the Bay up to 4-5 ft. For the ocean, winds may gust up to ~30 kt at times with seas up to 6-9 ft, highest over southern cstl wtrs. High pressure then slides into the area late Tue leading to improving marine conditions, with just some lingering 5-6 ft seas over southern cstl wtrs.
