.SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...
A weak cold front will near the region overnight tonight and during

thresholds later tonight through around midday Friday. Additionally,
ahead of the front, very moist warm air will override cooler MS

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.
