Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
216 PM EDT Thu Jun 20 2024

.SYNOPSIS...

Strong high pressure will sink southward over the western Atlantic
waters east of the Mid Atlantic coast through tonight with small
craft advisory conditions continuing over the local waters. Weak
troughing over the area waters will help to bring occasional light
showers across the waters through early this evening. Tonight, a
weak low currently northeast of the Bahamas will move westward as
the high to the northeast shifts more eastward into the western
Atlantic. The weak low will move onshore early Friday morning and
then exit to the west through the day towards the northeast Gulf
of Mexico. The pressure gradient between the high to the northeast
and the low moving through the region will continue small craft
advisory conditions through much of Friday before the pressure
gradient relaxes due to the low departing and the high weakening.
Seabreeze circulations will create increasing coverage of showers
and thunderstorms along the coast and local waters this weekend
as light southeast flow prevails. A cold front will approach early
next week with winds becoming more southerly and elevated chances
for showers and thunderstorms.
