.SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...
Surface high pressure will slide a little farther east allowing
southerly flow to increase a touch Thursday and Friday ahead of a
weak front that will likely not even reach the coast on Saturday.
This would keep light onshore flow over the region heading into next
week. Winds through the forecast should remain below adv criteria
with the main concerns being scattered showers and a few
thunderstorms late Friday and throughout the weekend.
