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 warm front overhead will lift slowly northeastward across the region through tonight. A cold front approaching from the upper Ohio Valley will follow for Monday. High pressure will build in from the Midwest Tuesday, then another cold front will approach from the west Wednesday into Thursday. A Small Craft Advisory may be needed for portions of the waters Wednesday night.
