.SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...
A warm front located near the coast will move inland today as a cold
front approaches from the west. Ahead of the cold front, expect
scattered showers and thunderstorms across the coastal waters
beginning late tonight. A tightening pressure gradient will also
cause winds to strengthen and exercise caution headlines have been
issued for portions of the outer waters late tonight. The front will
finally move through the coastal waters Tuesday night, with high
pressure building over the area in its wake. 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.
