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 powerful cold front will approach from the Ohio Valley this evening, then cross the Mid-Atlantic late tonight into Thursday morning. Another strong but mainly dry cold front will cross the region Friday night. A warm front will approach from the south Sunday. Small Craft Advisories will likely be needed Friday morning through Saturday morning, with gales possible Friday afternoon. Additional advisories may be needed Sunday.
