.SYNOPSIS...

A brief period of light offshore winds or variable winds will be
found over the coastal waters through tomorrow as a weak surface
boundary is over the coastal waters. This boundary will dissipate
with weak surface high becoming reestablished by mid week. This
will allow for light onshore winds to resume. There will be a
daily chance for isolated to widely scattered thunderstorms.
