.SYNOPSIS FOR THE TIDAL POTOMAC AND MD PORTION OF THE CHESAPEAKE BAY...
High pressure will gradually build in from the Ohio River Valley
today, then move offshore tonight as a cold front approaches from
the Great Lakes. The cold front will cross the Mid-Atlantic
Thursday, then linger nearby Friday into the weekend as one or more
waves of low pressure ride along the front stalled near the coast.
