Strong high pressure to the north will be the dominant
surface feature influencing the weather over the coastal waters with
gusty east-northeast winds reaching small craft advisory level at
times over the next couple of days. A cold front approaches the area
next week shifting winds and seas from the south by the Monday ahead
of the front and rain/storm chances will be on the increase. Winds
will further shift to the north-northwest by the middle of next week
in the wake of this front. Drier air and decreasing rain chances
expected into next week.
