.SYNOPSIS...
A frontal boundary will stall south of the forecast waters today and
into tonight. A wave of low pressure will then develop along
this front just south of the northeast Florida waters late
tonight with widespread rainfall and a few embedded thunderstorms
overspreading our local waters early Sunday into Sunday night.
Low pressure will move offshore on Sunday night, resulting in
strengthening northwest winds. High pressure will then build
over the southeast states early next week, creating strengthening
northerly winds and Small Craft Advisory conditions from Monday
through Tuesday evening.
