.SYNOPSIS FOR MID ATLC WATERS...A stationary front oriented SW to
NE will persist over or just E of the outer waters tonight
through Thu night as a series of weak low pressure centers track
NE along the frontal boundary. Weak high pressure will build E
across the northern waters late Wed into Thu night before
shifting E of the area by Fri. The stationary front over the far
outer waters will lift N as a weak warm front Fri into Fri night
as a weak low pressure trough develops over the far S waters. A
cold front will approach the coast from the W and NW Sat, move
offshore over the northern and central waters Sat night, and then
move slowly E and SE over the area Sun into Sun night as high
pressure builds over New England and the northern mid-Atlantic
states.
