Coastal Waters Forecast

National Weather Service Baltimore MD/Washington DC

FOR THE TIDAL POTOMAC AND MD PORTION OF THE CHESAPEAKE BAY.

Tidal Potomac River and Maryland portion of Chesapeake Bay. Forecasts of wave heights do not include effects of wind direction relative to tidal currents. Expect higher waves when winds are blowing against the tidal flow. Waves flat where waters are iced over. A surface trough will linger near the Chesapeake Bay today. Scattered showers and thunderstorms are possible mainly late this afternoon and evening. A cold front brings potential for more widespread strong thunderstorms Friday into Friday night. Small Craft Advisories may be needed in the wake of the front Friday night into Saturday morning. High pressure looks to return for at least the first half of this weekend resulting in lower rain chances before another frontal system approaches early next week. Small Craft Advisories may be needed in southerly channeling Sunday, though there is uncertainty in the timing of the arrival of the next front. Gusty winds and rain chances could return Sunday afternoon.
