952 PM EDT Wed Apr 29 2026
.SYNOPSIS...
A cold front will enter the southeastern states tonight with
showers and thunderstorms after midnight, mainly across the
Georgia waters through Thursday morning. This front will then
stall across the northeast Florida waters from late Thursday
through Friday, with scattered showers and thunderstorms possible
throughout our local waters. A wave of low pressure will then
develop over the Gulf by late Friday night or Saturday, with
widespread showers and possibly a few strong thunderstorms
overspreading our local waters on Saturday, with activity expected
to continue into Sunday morning. Small Craft Advisory conditions
may develop on Saturday afternoon as southwesterly winds increase
ahead of this approaching wave of low pressure. The front will
shift south of the northeast Florida waters late on Saturday
night, resulting in winds shifting to northwesterly and then
northerly on Sunday morning. Breezy northeasterly winds are then
expected on Sunday afternoon and night as high pressure builds
into the southeastern states.
