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

Fog will remain through much of each day and widespread overnight
into the end of the week which will likely bring additional marine
dense fog advisories, especially right along the coast. This fog may
not lift in many areas near the coast, but as land heating gets
going, we should see some erosion over water bodies that can move
this air over the water. The next front is due into the region early
next week. This will definitely move the fog issue away. Look for
winds to be on the increase very late in the period with this
feature as well which should produce headlines.
