Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
724 PM EST Tue Jan 19 2021

.SYNOPSIS...
High pressure centered over the northeast Florida waters this
evening will sink southward on Wednesday as a weak and dry cold
front passes southward through our region during the afternoon
hours. Weak low pressure developing over Texas late on Thursday
will move rapidly eastward across the Deep South on Friday, 
resulting in strengthening west southwesterly winds over our local
waters on Thursday night. This low pressure center will then move
across the southeast Georgia waters on Friday evening, pushing a 
cold front and showers into our region. This cold front will move 
south of our local waters by early Saturday, with winds becoming 
onshore by Saturday evening as high pressure shifts southeastward 
from the Upper Midwest into the Ohio Valley. High pressure will 
then wedge down the southeastern seaboard as it weakens on Sunday,
and a warm front will then lift northward from the Florida 
peninsula by Sunday night.
