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

As high pressure approaches from the Great Lakes, winds become
northeasterly through tonight before becoming southerly Tuesday as
this high slowly exits to the east. However, wind gusts remain below
 Small Craft Advisory Levels. Ahead of a cold front, winds increase
on Wednesday into Thursday which may necessitate some Small Craft
Advisories.
