Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-

.SYNOPSIS...
A weakening frontal boundary will stall across the southeastern
states on Friday afternoon, while a weak trough preceding this front
shifts southward across the northeast Florida waters. This trough
may develop widely scattered afternoon and evening thunderstorms,
mainly over the northeast Florida waters. The frontal boundary will
dissipate on Saturday as Atlantic high pressure lifts its axis to
the north of our local waters, resulting in a prevailing onshore
wind flow that will continue through next week. Only isolated to
widely scattered showers and thunderstorms are forecast across our
local waters during this time frame.
