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

Low pressure will track from West Virginia east over the waters

farther south Thursday as high pressure briefly builds from the Ohio
 Valley to New England. The front will then return north as a warm
front Friday night into Saturday as the high moves offshore and low
pressure moves from the Midwest to the Great Lakes.  A Small Craft
Advisory may be needed for a portion of the waters  Friday into
Friday night.
