Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
146 PM EST Thu Jan 22 2026
.SYNOPSIS...
High pressure positioned over coastal Georgia will weaken today as a
a frontal boundary slowly pushes towards the southeastern states.
Meanwhile, coastal troughing is situated offshore, but will weaken
by Friday. Patchy fog with visibility of 1 NM or less is forecast
along nearshore waters late tonight and Friday morning. Arctic
high pressure will build northwest of the area on Friday and push
the frontal boundary southward, crossing our local waters on
Friday night. Northeast winds will briefly surge in the wake of
this frontal passage on Saturday with a small craft advisory
possible north waters. Meanwhile, a winter storm developing over
Texas and the lower Mississippi Valleys on Saturday and Saturday
night will shift northeast, lifting a warm front northward across
our local waters on Saturday night. Winds will shift to south and
then southwest on Sunday ahead of another cold front, which could
be accompanied by a few thunderstorms on Sunday afternoon and
night. Another Arctic high pressure center will then build into
the southeast states in the wake of this cold frontal passage
early next week, with Small Craft Advisory conditions expected as
breezy northwest winds shift to north while strengthening further
on Monday night.
