Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
942 PM EDT Wed Apr 8 2020

.SYNOPSIS...
Showers and a few strong thunderstorms containing gusty winds,
frequent lightning strikes and downpours will continue over the
waters north of St. Augustine through around midnight. Otherwise,
breezy west-southwesterly winds will continue well ahead of a 
cold front that will dive into the southeastern states on Thursday
morning. This front will cross our local waters from north to 
south after midnight Thursday night, with a brief period of Small 
Craft Advisory conditions and showers expected on Friday morning 
as north-northwesterly winds surge in the wake of this departing 
front. High pressure will then build into the southeastern states 
on Friday evening, allowing for winds and seas to briefly subside.
High pressure will move off the Carolina coastline by Saturday 
evening, with light onshore winds resuming on Saturday followed by
steadily increasing southeasterly winds Saturday night as 
Atlantic high pressure strengthens downstream of a developing 
storm system over the southern Plains states. Strong southerly 
winds will prevail Sunday through Monday, with Small Craft 
Advisories likely and increasing chances for showers and 
thunderstorms.
