SYNOPSIS
A cold front will move S across the waters tonight and Tue while weakening. High pressure will build E into the region Tue and Tue night, then move S across the S waters Wed and Wed night before shifting S of the region Thu and Thu night while maintaining a ridge across the far S waters through Sat night. A warm front will extend E off the Mid- Atlantic coast Wed and Wed night as low pressure tracks E along the boundary. The low will pull a cold front over the region Wed through Thu night. A secondary cold front will move S over the area Thu night and Fri, before the front stalls over the central waters Fri night through Sat night as low pressure tracks E along the boundary. A high pressure ridge will build SE over the N portion Fri night into Sat night.
