SYNOPSIS FOR NEW ENGLAND WATERS
A reinforcing cold front will move S across the waters tonight followed by another cold front or low pressure trough Tue. A strong high pressure ridge will build E toward the region late tonight, move offshore Tue, and then weaken over the waters Tue and Tue night. Low pressure will develop and pass S of the waters Tue night, strengthen to the SE and E of the waters Wed, and then move well E of the area Wed night and Thu while intensifying. High pressure will slowly build E over the region late Wed and Wed night, and then weaken while shifting E of the area Thu into Thu night. Yet another low will develop S of the waters Thu and Thu night while tracking NE towards Georges Bank. The low will pass just SE of the waters Fri, and move off to the E of the area Fri night as a high pressure ridge builds E towards the coast. Another low is expected to develop off the SE United States Fri night, remain to the S and SE of the area early Sat, and then strengthen Sat and Sat night while moving off to the NE.
