Dense Fog Advisory

.SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...
Light southwesterly winds of around 10 knots or less and seas of
2 feet or less will be in place through Wednesday. Wednesday night
and a surface low will begin to take shape and deepen over the OK
and TX panhandles and move across the southern and central Plains
during the day. At the same time high pressure dominating the Gulf
will slide northeast and this will cause the winds to increase and
become more southerly. Moderate onshore flow will continue through
Friday night until a cold front moves through Saturday with a window
of strong offshore winds. There will likely need to be some
headlines behind the cold front with either an SCY or SCS needed.
Rain chances will begin to increase Thursday however, Friday and
Friday night into Saturday morning will have the greatest potential
for rain with the best chance of thunderstorms some likely strong
Friday night and early Saturday.
One last impact to mention. With days of onshore flow prior to the
cold front we will have a rather well set up fetch out of the south.
With winds quickly veering around to the north-northwest immediately
behind the cold front there will be a window of what is called
confused seas. The greatest potential appears to be in the outer
waters (20-60nm) and west of the mouth of the MS River.
