.SYNOPSIS FOR MID ATLC WATERS...A stationary front extending E
over the waters from near Cape Fear will persist today, and then
return N as a weak warm front tonight into Mon. Meanwhile, high
pressure across the waters behind the front will shifts E today
and tonight. Low pressure moves to near Long Island late tonight,
then tracks slowly E across waters just N of the area Mon
through Tue, before clearing NE of the area Tue night into Wed.
The low pulls a cold front across the N portions Mon and Mon
night, with the front stalling over the central waters Tue
through Wed night while slowly weakening. The front will slowly
return N as a weak warm front Thu, reaching the N waters Thu
night.
