Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
915 PM EDT Tue May 24 2022

SYNOPSIS

Atlantic high pressure will remain positioned off the southeastern
seaboard through Wednesday night, resulting in a prevailing
southeasterly wind flow. Meanwhile, a stalled frontal boundary
positioned across the Carolinas will lift northward as a warm
front on Thursday as a cold front pushes into the southeastern
states by Thursday evening, resulting in strengthening southeasterly
winds. This frontal boundary will then slow its forward progress
as it approaches our local waters on Friday, bringing increasing
chances for showers and thunderstorms. This front will weaken over
our coastal waters during the Memorial Day weekend, resulting in
decreasing chances for showers and thunderstorms as a weak
pressure pattern prevails.
