1228 AM EST Thu Nov 13 2025

.SYNOPSIS...

High pressure positioned over the Florida peninsula will continue to
slowly weaken and slide southward on Thursday as a dry and weak
frontal boundary pushes southward towards the Georgia waters. Breezy
westerly winds offshore with shift to northwesterly after midnight,
with speeds gradually weakening ahead of the frontal passage on
Thursday afternoon. Another high pressure center will build over the
southeastern states on Friday in the wake of the frontal passage,
resulting in a brief period of northeasterly winds. High pressure
will then weaken as it settles directly over our local waters on
Friday night and Saturday. This feature will then shift southward on
Saturday night and Sunday, resulting in strengthening southwesterly
winds ahead of the next dry frontal passage that is expected on
Sunday night or early Monday morning.
