area moves to near Long Island late tonight, then tracks slowly E
over the S waters while strengthening Mon into Tue, with the

weaken. Weak high pressure will build E into the area Wed, and 
slide off to the E Wed night as a weak cold front moves off the 
coast. The front will move SE over the waters Thu, and pass S and
E of the area Thu night. High pressure will build E over New 
England Thu night, and move E and NE over the waters Fri into Fri
