.SYNOPSIS...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 or
weak cold front 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.
