322 AM EST Tue Dec 9 2025

.SYNOPSIS FOR NEW ENGLAND WATERS...High pressure will build E
across the waters today. The high will shift E tonight as weak 
low pressure develops and moves NE along the Maine coast, pulling
a weak warm front NE across the area. Another warm front will 
lift N across the waters Wed ahead of a stronger area of low 
pressure moving E into northern New England. A strong cold front 
associated with this system will sweep E and SE over the area 
Wed night into Thu, followed by a secondary cold front or low
pressure trough Thu night into Fri. High pressure to the S will 
build E and extend a ridge across the waters Fri night into Sat. 
Another trough will cross the area Sat as the ridge shifts E and
weakens. During Sat night, developing low pressure with a warm 
front extending E from the low will approach from the SW. A cold
front will approach the coast from the W late Sat night.

.SYNOPSIS FOR MID ATLC WATERS...Strengthening low pressure just E
of the southern waters early this morning will move E and NE 
away from the area today as high pressure builds into the 
northern and central portions. The high will shift E of the area

Wed, move E and SE across the waters Wed night, then clear E of 
the area Thu. High pressure will move E across the area Thu night 
into Fri, then persist into Sat while weakening. Developing low 
pressure and associated warm and cold fronts will approach the 
waters late Sat. The warm front will lift across the northern 
waters Sat night as the developing low and cold front approach 
the coast or begin to move just offshore.
