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 cold front will slowly approach from Pennsylvania today as a warm front approaches from the Virginia Tidewater and Delmarva Peninsula. Multiple weak waves of low pressure along these boundaries will ignite scattered to numerous showers and thunderstorms. Some storms may be severe particularly east of the Blue Ridge and Catoctin Mountains, and especially across the Interstate 95 corridor toward the Chesapeake Bay. This frontal system is expected to stall near or just southeast of the Mid-Atlantic, and additional ripples of low pressure riding along it may result in periodic showers and a few thunderstorms at times through the upcoming weekend.
