Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
1048 AM EST Wed Feb 12 2025

.SYNOPSIS...

Low pressure organizing over the lower Mississippi Valley this
afternoon will strengthen as it accelerates north-northeastward
tonight, reaching the eastern Great Lakes by early Thursday.
Southerly winds will strengthen this afternoon well ahead of this
developing storm system. This storm system`s trailing cold front
will approach our local waters on Thursday afternoon, accompanied
by showers and possibly a few thunderstorms. Strong high pressure
building into the Tennessee and Ohio Valleys in the wake of this
frontal passage will result in winds abruptly shifting to
northerly towards midnight on Thursday night, followed by gusty
northeasterly winds and Small Craft Advisory conditions throughout
our local waters on Friday and Friday night. High pressure will
then shift offshore of the Mid-Atlantic coast by Saturday morning,
resulting in winds shifting to southeasterly early in the day and
then southerly by the afternoon hours as a warm front lifts
northward from the Florida peninsula, possibly accompanied by a
few showers.

Another low pressure center will develop over the Tennessee and
Ohio Valleys on Saturday evening, with this storm system
strengthening as it accelerates northeastward, reaching New
England by Sunday afternoon. Southwesterly winds will strengthen
late Saturday night and Sunday ahead of this storm system`s
approaching cold front, which will be accompanied by showers and
possibly a few strong thunderstorms during the afternoon and
evening hours. Small Craft Advisory conditions are expected
offshore on Sunday and Sunday night, with strong northwesterly
winds overspreading our local waters in the wake of this frontal
passage towards midnight.
