.SYNOPSIS FOR MID ATLC WATERS...A series of surface troughs will
continue to move S across the N waters early this morning around
broad low pressure over Atlantic Canada, as high pressure will be
located over the S waters. A warm front should emerge off of the
central waters today under overall weak, broad high pressure. The
warm front will move N tonight while a cold front approaches from
the NW. The cold front should sweep quickly E over the N waters
by Sun afternoon and through the S waters overnight Sun and into
Mon. While high pressure will then build over the S waters,
around persistent, broad low pressure over SE Canada, another
series of surface troughs will pass from NW to SE over the N
waters Mon through Tue night. High pressure then gradually builds
E over most of the waters Wed and Wed night. However, a surface
front may develop off of the Carolina coast late Tue night with
weak low pressure possibly moving E along the front and off of
the coast Wed night.
