.MARINE... High pressure dominates across the region today into tonight. Winds will be light today through Thursday as a cold front slowly sags south over the waters. Numerous thunderstorms are likely to move across the area, and these will pose a threat to mariners from gusty winds and lightning strikes. Small Craft Advisories are likely on Friday as northerly winds gust 15 to 20 knots over the waters. Small Craft Advisory conditions may linger into Saturday for portions of the waters in northeasterly flow. Lighter east winds are forecast Sunday as high pressure slides by to the north.
