.SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...
As high pressure continues to shift eastward, a moderate onshore
flow of 10 to 15 knots will persist through the end of the week. A
strong cold front will move through the coastal waters Saturday
night into Sunday morning with high pressure building in again
behind it. The combination of a tight pressure gradient and cold air
advection will cause winds to strengthen and turn offshore again
Saturday night with small craft advisories likely necessary through
at least Sunday evening.
