.SYNOPSIS...

A frontal boundary will remain stalled south of the coastal waters
tonight continuing light showers. A wave of low pressure will then
develop along this front and move south of the northeast Florida

thunderstorm Sunday into Sunday night over the Florida waters. Low
pressure will move offshore on Sunday night, resulting in breezy
north-northwest winds. Northerly winds then strengthen to Small
Craft Advisory levels early next week as high pressure builds over
the southeast states.
