.SYNOPSIS FOR MID ATLC WATERS...A stationary front extending E
across the N waters will pass N of the area today. A cold front
will approach the Mid-Atlantic coast late today, then pass E and
SE over the region tonight into Wed night while weakening. In
association with the front, widespread thunderstorms are expected
to move offshore late today and tonight. Mariners should use
caution for gusty winds and rough seas in and near the heavier
thunderstorms. Developing low pressure will move off the northern
Mid-Atlantic coast Wed night, then track NE across the northern
portions later Wed night into Thu while a secondary cold front
moves E and SE across the waters. High pressure will build slowly
E to the coast Thu night through Fri night.
