.Synopsis for the Long Island and Connecticut coastal waters...
A frontal system impacts the waters late tonight through Saturday
evening. High pressure builds to the west during Sunday, and over
the area Sunday night through Monday. The high pushes off the
Mid- Atlantic Coast Monday night which allows a warm front to
approach and then lift north Tuesday night. This will be followed
by a cold frontal passage Wednesday. High pressure then builds in
from the northwest through Wednesday night, pushing off Thursday.
This will allow another frontal system to approach and affect the
area at the end of next week.
