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

A weak frontal boundary will remain stalled along the coast of
Louisiana through tonight. This will keep a persistent east wind of
10 to 15 knots and slightly higher seas of around 2 feet in place. 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.
