winds and rough seas in and near locally heavy tstms over the

drift E while passing N and then NE of the area Sun night into
Tue as a series of secondary cold fronts or low pressure troughs
move E and SE over the N and central areas. A weak high pressure
ridge will build S and SE over the region later Tue and Tue night
as a warm front extends E off the SE coast. The warm front will
lift N across the area Wed and Wed night. A developing low
pressure area will approach from the W and SW, and then move NE
along or just off of the Delmarva or New Jersey coast Wed night.
The developing low pressure will move N of the area by early Thu
with a trailing cold front moving E and SE across the waters Thu
