.DISCUSSION...
Northeast winds continue overnight and through Sunday. Winds
should continue to calm through Sunday morning, and wave heights

lingering wave swell may persist. There is a 20 percent chance for
an isolated rain shower, and some lightning could be possible
(around a 5% chance in any shower that develops). The best
chance for any precipitation is around midnight, decreasing
through the early morning hours. Water surface temperatures should
