Conditions given represent the highest within that period.

.SYNOPSIS FOR MID ATLC WATERS...A high pressure ridge will
persist across the S waters today through Thu night. A stationary
front will linger along the N and central mid-Atlantic coast
today and tonight. Low pressure along the front will move E
today, passing E of the area tonight into Wed. A low pressure
trough will strengthen inland and over the N and central
mid-Atlantic coast Wed and Wed night, with a warm front
developing and lifting NE and passing N of the waters Wed night.
A cold front will approach from the W and NW Thu, then move
offshore Thu night into Fri. The cold front will stall as it
moves SE over the central waters Fri, then dissipate by Fri night
as high pressure builds over the mid-Atlantic and S parts Sat and
Sat night.
