.SYNOPSIS FOR THE TIDAL POTOMAC AND MD PORTION OF THE CHESAPEAKE BAY...

Upper level disturbances will track across the area today  leading
to additional cold blustery winds. Surface high pressure  builds
well to the south through Wednesday. A progressive frontal  system
pushes through the waters late Wednesday before high pressure
returns by late in the week and into the weekend. Small Craft
Advisories will likely need to be extended from tonight through
Thursday as a result.
