front emerges off of the Carolina coast Tue night. Low pressure
will move ENE along the front, moving slowly offshore Wed and
then gradually moving ENE farther offshore through Thu night
before finally moving well out into the N Atlantic Fri. High
pressure briefly builds over the waters Fri. A cold front
approaching from the NW late Fri will move over the N waters Fri
night and early Sat, gradually moving through the central waters
Sat and into the S waters Sat night. High pressure will build SE
over the N waters behind the front Sat and Sat night. Low
