 .SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...
 
 Surface high-pressure axis over the southern Gulf is being absorbed
 by the Bermuda ridge. The low-level pressure gradient may tighten
 slightly Friday into the weekend as surface high pressure becomes
 better established over the eastern Gulf while lower pressures
 persist over the southern Plains and lower Mississippi Valley. This
 will alter flow to more of a south to southeast direction Thursday
 and then southeasterly to easterly through the weekend. Speeds
 should generally remain around 5 to 10 knots, although periods of
 10 to 15 knots will be possible over the outer waters as an easterly
 fetch becomes better established late in the week. Seas will
 generally remain 1 to 2 feet through Thursday.
 
 Increasing Gulf moisture will also bring a gradual increase in
 showers and thunderstorms beginning Thursday and continuing through
 the weekend and into early next week. Convection will be most
 common, in typical summertime fashion, over the coastal waters
 during the overnight and morning hours. Then activity shifts inland
 with the developing sea breeze during the afternoons.
