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

High pressure building in from the east will keep winds out of the
south or southeast through Sunday. For the early portion of the new
week, the center of the high may move west of the area, producing
light northerly winds. An easterly wave moving across the northern
Gulf will increase the threat of thunderstorms at midweek,
potentially as early as Tuesday night, and continuing through the end
of the week.
