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

A weak cold front moves through the are tonight and during the day
on Friday. In conjunction with the front winds will increase to
Small Craft Advisory thresholds later tonight through around midday
Friday. Ahead of the front, very moist warm air was overriding
cooler MS Sound waters which led to the development of sea fog this
afternoon. With increasing winds tonight the sea fog is expected to
dissipate by midnight. High pressure spreads into the region this
weekend allowing for more favorable marine conditions to take shape
on Saturday before more moderate winds and seas develop early next
week.
