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

The actual front will finally move through the coastal waters
Wednesday morning as deepening comma low rolls into the Great Lakes
Region. The combination of cold air advection over the relatively
warm waters, and the pressure gradient between the high and low will
cause winds to strengthen into the 20-25kt range and Small Craft
Advisories will likely be needed Wednesday afternoon through at
least midday Thursday. As the high settles into the area later in
the week, winds will ease and turn back to the southeast as the high
shifts east of the area by Saturday.
