.SYNOPSIS FOR MID ATLC WATERS...A secondary cold front or surface
trough will approach from the NW tonight and move through the 
northern waters tonight and Sat. Otherwise, high pressure will 
build over the southern waters. A cold NW flow will then be in 
place Sat night through Mon with a ridge extending northwest- 
to- southeast over the southern waters. A surface front will 
develop off the Carolina coast on Mon, remaining nearly 
stationary through Tue with lows moving E along the front. High 
pressure then builds S Tue night into Wed as a cold front moves 
south of the waters. Developing low pressure occurs near the SE 
U.S. coast Wed night. Mariners should monitor later forecasts for
updates on the strength and timing of conditions associated with
the low later next week.
