Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
937 PM EDT Fri May 29 2026
.SYNOPSIS...
A stationary frontal boundary over the local waters Tonight,
will lift slowly to the north as a warm front on Saturday.
Meanwhile, high pressure building over the Great Lakes will drive
a cold front into the southeastern states on Saturday afternoon,
with this front stalling near the Florida and Georgia border on
Sunday. Showers and thunderstorms will continue through the
upcoming weekend and into Monday evening. A stronger cold front
will then sweep southward across our area on Tuesday, with this
boundary likely stalling south of our local waters by midweek.
High pressure will wedge down the southeastern seaboard in the
wake of this frontal passage, creating breezy northeasterly winds
beginning on Tuesday evening and likely persisting through at
least Thursday evening.
