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. High pressure will move further offshore today as a warm front lifts away from the region. A surface trough will linger west of the waters near the Blue Ridge Mountains this afternoon before drifting southeastward across the waters tonight into Thursday. This trough may ignite multiple rounds of showers and thunderstorms. 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.
