.SYNOPSIS FOR MID ATLC WATERS...High pressure over the far NE
waters will shift E of the area today. Low pressure will approach
the southern and central waters from the W today while pulling a
strong cold front over the area, then move NE along the coast
tonight into Thu as the front continues E through the waters. A
low pressure trough will move E across the region Wed night and
Thu. A high pressure ridge will build E and NE over the area Thu
night into Fri, then shift NE of the region late Fri. Weak low
pressure will approach the area from the W Fri, and move NE
across the northern waters Fri night while pulling a weak cold
front over the region. The low will pass N of the area Sat as the
front continues slowly E over the waters. Another weak cold front
will move SE over the northern waters Sat night as high pressure
builds W of the area.
