.SYNOPSIS...

A weakening frontal boundary over Georgia will continue shifting
southward into the local Georgia waters tonight. The boundary will
stall tonight into the holiday weekend bringing waves of showers and
thunderstorms. An area of weak low pressure will develop along the
frontal boundary and move over the coastal waters on Friday. The low
will linger over the coastal waters this weekend potentially
bringing Small Craft Advisory conditions before lifting northward by
early next week. NHC is currently monitoring this system to see if
the low will become a tropical or subtropical depression.
