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

High pressure builds over New England, while an area of low pressure
will likely pass by to the south. This system eventually evolves
into a coastal low across the Atlantic Ocean later this evening
before tracking out to sea. High pressure briefly builds over the
area this weekend while a stronger cold front crosses the waters by
late Sunday. A strong area of Canadian high pressure builds over
the region on Monday into Tuesday. Small Craft Advisories will
likely be needed on Monday, and possibly again on Tuesday.
