1008 AM EDT Sat Nov 1 2025

.SYNOPSIS...

High pressure positioned over our area this morning will weaken
this afternoon as a cold front enters the southeastern states.
Coastal troughing will develop ahead of this approaching front
over our local waters tonight, with this feature sharpening on
Sunday and likely developing into a weak low pressure center off
the southeastern seaboard by Sunday night. Meanwhile, the cold
front will cross our local waters on Sunday night, accompanied by
scattered showers. Weak low pressure organizing over the Gulf
Stream waters may develop a few thunderstorms offshore by Monday
afternoon. Northerly winds will strengthen in the wake of the
frontal passage on Monday and Monday night, with Caution
conditions expected near shore and Small Craft Advisory conditions
possible offshore. High pressure will then build into the
southeastern states on Tuesday and Wednesday, with northeasterly
winds expected to gradually subside on Tuesday night across our
local waters.
