.SYNOPSIS FOR MID ATLC WATERS...Strengthening low pressure just E
of the northern waters will move NE away from the waters tonight
as a cold front moves offshore over the northern waters. Weak
high pressure will persist over the central and S waters tonight
into Sat. The front will move E of the N waters Sat as high
pressure expands from the central into the northern waters, as
weak low pressure develops along a stationary front over the far
southern waters. The low will move E and NE over the far S waters
Sat night into Sun as the high retreats N to the N waters. The
low will move NE and pass E of the southern and central waters
Sun night into Mon as the high retreats N to the New England
waters. A ridge associated with the high to the N of the area
will develop over the inner waters Mon night into Tue as the low
moves off to the E and NE of the area. Weak high pressure will
cover most of the N and central waters Tue night into Wed as a
front to the S of the waters begins to return N as a warm front.
The front and a developing low pressure area will lift N over the
southern waters Wed night as the ridge dissipates.
