.SYNOPSIS FOR NEW ENGLAND WATERS...Low pressure over New Jersey
early tonight will track N and NE near the New England coast
later tonight into Thu, and then move over Maine by later Thu.
The low will pull a warm front N into the region tonight, then
pull a cold front E over the waters later tonight into Thu. A
low pressure trough will pass E through the waters later Thu and
Thu night before weak high pressure quickly moves E over the
area Fri. Weak low pressure will approach from the SW by Fri
night, and move NE over the area Fri night into early Sat as
another cold front approaches the waters from the NW. The cold
front will move SE over the area Sat night, followed by a
secondary cold front late Sun. High pressure will build SE over
the eastern states Sun night, and persist to the SW of the
waters Mon and Mon night.
