.SYNOPSIS FOR MID ATLC WATERS...A broad low pressure area just E
of the northern waters, centered about 330 nm SE of Nantucket,
will move slowly E away from the area today and tonight. A cold
front extending SW across the SE portion of the waters will move
slowly S today, as a series of weak low pressure centers form and
move E along the boundary. The front will pass S of the area
tonight and Tue while high pressure builds S into the northern
waters. The high pressure ridge will slowly drift S Tue night
through Thu while weakening, and then will shift S of the waters
Thu night where it will persist through Fri night. A cold front
will approach the northern Mid-Atlantic coast Thu night and early
Fri, with the front crossing the northern waters later Fri and
Fri night.
