.MARINE... A brief period of southerly channeling may return to the middle and open waters of the Chesapeake Bay this afternoon and evening with sub-SCA level winds over most of the waters. Overall sub-SCA level winds are expected through Wednesday. Wind speed and direction are a bit uncertain Thursday and Friday as a cold front gradually pushes through the area. While winds appear to be mostly sub-SCA at this time, there could be an enhanced northwesterly surge once the front does push through. Outside of the background winds, expect daily shower and thunderstorm chances are each afternoon and evening through upcoming workweek. Special Marine Warnings may be needed to encompass any stronger thunderstorms that may form especially today through Thursday. Damaging wind gusts and frequent cloud-to-ground lightning will be the main threats between 18z-01z/ 2-9pm. Update as of: 234 AM EDT Mon Aug 10 2026
