.SYNOPSIS FOR MID ATLC WATERS...A cold front over the central and
N waters will stall and weaken over the central waters later
today and tonight then dissipate Mon . Low pressure along another
stationary front across the far S waters will move NE today then
pass E of the southern waters tonight. This low moves well NE of
the NE waters Tue night. High pressure will builds in, while to
the S, the low will continue to slowly move E along the front,
farther offshore. The low will be followed by a series of weak
lows that develop along the meandering front and also move NE
through Wed. With high pressure returning over the N waters by
Wed, the front to the S should start to move N as a warm front
Wed night. The high over the N waters shifts E on Thu. The front
then moves slowly N over the area Thu and Thu night attached to
low pressure moving N along and near the east coast.
