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

A weak frontal boundary will remain stalled along the coast of
Louisiana through Wednesday. This will keep a persistent east wind
of 10 to 15 knots and slightly higher seas of around 2 feet in place
through the mid-week. A much stronger front will push through the
waters Wednesday night and winds will shift to the north. A drier
surface high will then settle in for Thursday and Friday with very
low rain chances. This high will begin to move to the east on
Saturday allowing for a light southerly flow to develop. Offshore
shower and thunderstorm activity will also increase a bit as
moisture feeds back into the area.
