.SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...

Surface high pressure will generally remain centered east of the
local area through Thursday with light onshore flow. Friday, a

trailing cold front moving near the area late Friday and Saturday.
Slightly stronger onshore winds will occur in response to the
surface low and approaching front. However, confidence is low that
we may need headlines this weekend.
