.SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...
Surface high pressure will generally remain east of the local area
through most of the week. This will keep flow oriented onshore and
fairly light through mid week. Late week, the pressure gradient will
tighten as a surface low develops over West Texas and moves through
the southern portion of the Central Plains. Onshore winds will
strengthen in response to this. Guidance suggests at least
15-20 knots in open Gulf waters Thursday and Friday with seas
3-6 feet. Model consistency falls off a bit after that. The last few
days they suggested a decent from coming in from the west to NW, now
models are showing the upper low driving this will be opening and
flattening out as it moves across the mid section of the country
which will result in a much weaker cold front that lays over as it
reaches the local coastal waters.
