.SYNOPSIS FOR NEW ENGLAND WATERS...A high pressure ridge over the
Georges Bank this evening will shift E of the area early 
tonight. A warm front will lift N across the waters tonight as 
weak low pressure tracks E and NE over the Gulf of Maine while 
pulling a cold front over the region. Another cold front will 
move across the area Mon, then pass SE of the waters Mon night. 
The front will stall S of the area Tue into Tue night as low 
pressure forms along the boundary, then slowly weaken Wed into 
Thu night. Strong high pressure will build slowly SE over the 
region Mon night into Wed night, then slowly shift E of the area 
Thu and Thu night as a weak cold front moves slowly SE over the 
waters. The front will dissipate over the area Fri and Fri night 
as another high builds SE over the region.
