As that low moves quickly NE and then N away from the area, a cold front extending S from the low will move SE across the northern and central waters tonight and Fri, reaching the southern waters Fri night. On Sat, a new weaker area of low pressure will develop W of the waters. It will move E into the northern waters Sat night into Sun before weakening into a trough Sun night. The low will drag a cold front across the central and southern waters Sun night through Mon night. An additional weak and broad area of troughing will extend S from broad low pressure N of the area and will move E across the northern waters Mon into Tue. The low should dissipate later Tue into Tue as weak ridging builds across the area.
