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

A broad surface ridge extending across the Southeast continues to
settle southward toward the northern Gulf Coast. As the ridge moves
closer, the pressure gradient will relax further and winds will
remain generally light, gradually becoming more onshore. Shower and
thunderstorm coverage should increase somewhat Monday as moisture
returns and upper-level subsidence weakens. Any thunderstorm could
produce locally higher winds and seas, but widespread marine hazards
are not anticipated. Surface high pressure should remain close
enough to the northern Gulf Coast through much of the week to
maintain a relatively weak gradient. A somewhat more persistent
northeast to east flow may develop by the middle to latter part of
the week as high pressure builds to the north.
