.SYNOPSIS...

this morning while weakening, allowing for winds and seas to
diminish. This high pressure center will shift southward over the
Florida peninsula this evening and Saturday, allowing for light
south to southwest winds to develop. Another Arctic cold front
will enter the southeastern states on Saturday afternoon, crossing
our local waters on Sunday morning. This front will be accompanied
by showers through the early afternoon hours on Sunday.
Northwesterly winds will strengthen by early Sunday morning, with
Small Craft Advisory conditions likely through Sunday evening
throughout our local waters. Arctic high pressure will remain
centered to the west of our region early next week, keeping breezy
northwest to northerly winds and elevated seas in place. High
