.SYNOPSIS...
Strong low pressure off the mid-Atlantic coast will track further

through this evening, ending small craft conditions. High pressure
will shift over the region Sunday and Monday with prevailing west to
southwest winds, turning southeasterly in the afternoon nearshore
from the Atlantic seabreeze circulation. High pressure will shift
east of the waters midweek with southerly winds, turning easterly in
the afternoon over the nearshore waters from seabreeze circulation.
Increasing moisture will bring a return of scattered showers and
isolated thunderstorms over the waters by midweek.
