.SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...
A broad surface high centered over the Tennessee Valley encompasses
the southeastern US. This ridge will slightly weaken while tracking
southward, becoming centered across the northern Gulf Coast Sunday.
Local winds will respond to this by weakening and becoming more
onshore. Weaker winds will persist throughout the remainder of the
forecast period as that ridge remains nearby.
