SYNOPSIS
High pressure will build E over the region today, then shift SE of the waters later today and tonight as a warm front lifts N over the area. A cold front will move E across the waters Thu into Thu night, followed by a secondary cold front Thu night into Fri. Another high will pass S of the region Fri, before a stronger cold front crosses the area late Fri into Fri night. High pressure will build NW and N of the region Sat and Sat night, then shift N Sun and Sun night. Low pressure will develop S of the area Sat night, then slowly track N into the S waters late Sun and Sun night. Mariners are advised to monitor the latest OPC forecasts for this potential developing system.
