.SYNOPSIS FOR MID ATLC WATERS...A cold front will stall across 
the S waters tonight and will dissipate Sun. A secondary cold 
front will move into the area tonight, and then stall and weaken 
across the northern waters Sun. High pressure will quickly move 
SE across the waters Sun and Sun night, and will maintain a ridge
over the southern zones into Mon. A warm front will lift N over 
the N waters Sun night into Mon. Low pressure will form over the 
southern waters Mon night, then move N across the outer waters 
Tue as another low pressure moves E off the northern Mid- 
Atlantic coast. The two lows will merge over the northern waters 
Tue night, and then move E Wed and Wed night. The low will then 
pass E of the waters Thu and Thu night as another ridge builds SE
towards the region. Another cold front will move E off the SE 
coast Thu and Thu night.
