A stronger low will develop and move E along the stalled front Mon into Tue, before passing E of the region late Tue and Tue night. Mariners should closely monitor the latest forecast and consider avoidance routing as the low has the potential to become intense as it moves E over the southern portion of the waters Mon night into Tue. Otherwise, a high pressure ridge will move over the waters Tue night and Wed, then shift E of the region Wed night. A weakening cold front will move SE over the N portion Wed, stall Wed night, and begin to return N as a warm front later Wed night. The warm front will lift N across the northern Mid-Atlantic and New England waters Thu into Fri night, while a high pressure ridge slowly shifts N across the southern waters.
