450 PM EST Wed Dec 3 2025

.SYNOPSIS...

High pressure will build over the southeastern states tonight and
Thursday. Low pressure will then organize along the northern Gulf
coast on Thursday night, with a warm front lifting northward across
our local waters on Friday, accompanied by an increasing coverage of
showers. Weak low pressure will move northeastward across
southeastern Georgia on Friday evening, with this storm system`s
cold front then crossing our local waters on Friday night and
Saturday morning. A wave of low pressure will then develop along
this front just south of the northeast Florida waters on Saturday
night, keeping showers and a few embedded thunderstorms over our
local waters through Sunday. Low pressure will then strengthen as it
moves offshore on Sunday night and Monday, resulting in
strengthening north northwesterly winds as rainfall ends.
