.SYNOPSIS...

High pressure wedged down the southeastern seaboard will remain
through Tuesday. Gusty easterly winds and Small Craft Advisory
conditions with rough, elevated seas will also continue. High
pressure will shift offshore of the Mid-Atlantic coast by Tuesday
night and Wednesday, allowing coastal troughing and associated winds
to weaken. An approaching cold front will shift slowly southward
across our local waters by Thursday night and Friday. Strong
northeasterly winds will then redevelop late this week as another
high pressure center building over New England wedges down the
southeastern seaboard.
