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.

A cold front will surge southward tonight. An area of low pressure will traverse the boundary Friday as it stalls across the Ohio Valley and Carolinas. A second wave of low pressure will drive a stronger cold front across the area Sunday night into Monday. Small Craft Advisories may be needed Saturday. Advisories will likely be needed Sunday night into Monday. Gale conditions are possible Monday into Monday night.
