.SYNOPSIS FOR MID ATLC WATERS...A series of weak low pressure
troughs will meander across the central and S portions tonight
into Thu, while high pressure persists across the N areas. The
high will shift E early Thu ahead of an approaching cold front
from the NW. The front will move slowly into the N portions by
later Thu, then stall Thu night. Low pressure will develop along
the stalled boundary late Thu night into early Fri, just offshore
the Mid-Atlantic coast, then track E and NE along the front Fri
night. The low will clear well E into the N Atlantic Sat, pulling
the cold front slightly further S later Sat, before stalling
again across the central and S areas late Sat through Sun night.
High pressure will build across the N portions Sun and Sun night.
