1229 AM EST Thu Dec 4 2025
.SYNOPSIS...
High pressure will build over the southeastern states today with low
pressure organizing along the northern Gulf coast tonight, 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.
