.SYNOPSIS...
Arctic cold front will approach the region this afternoon and
evening with prevailing southerly winds. Showers will overspread our
local waters as this front passes through late tonight and Sunday
morning. Northwesterly winds will strengthen after midnight,
reaching Small Craft Advisory levels on Sunday morning. Arctic high
pressure will remain centered to the west or northwest of our region
early next week, keeping breezy northwest to northerly winds and
elevated seas in place through midweek. High pressure will then
weaken over the southeastern states on Wednesday, allowing for
onshore winds to develop across our local waters. Weak low pressure
traversing the northern Gulf coast on Wednesday night and Thursday
may spread a round of scattered showers through Thursday night,
mainly for the northeast Florida waters.
