.SYNOPSIS...
Broad influence from a high pressure situated near Bermuda through
the weekend and at least through the middle of next week. The
western axis of high pressure will be north of the local waters
resulting in southerly winds, that will increase during the
afternoon hours as the sea breeze develops. Seas will build to 4 to
5 feet during the enhanced southeasterly winds behind the sea breeze
and small craft should exercise caution. Only isolated to widely
scattered showers and thunderstorms are expected across our local
waters, with increasing chances possible towards the middle portion
of next week.
