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. Brief high pressure will return to the waters today with a warm front set to cross late tonight into Wednesday morning. A cold front will cross the waters Wednesday into Thursday with an area of low pressure passing to the south Thursday night into early Friday. High pressure returns for the weekend with a stronger front early next week. Additional Small Craft Advisories may be needed at times for portions of the waters during this period.
