Synopsis for Lower Atchafalaya River LA to High Island TX out
60 NM including Sabine and Calcasieu Lakes and Vermilion Bay
917 PM CST Mon Feb 19 2018

.SYNOPSIS...

Tight pressure gradient across the region will persist into
Tuesday with a surface low over the Plains and high pressure just
off the Atlantic coast. The result will be moderate and gusty
south winds. With warm moist air moving over relatively cooler
Gulf shelf water, there will be the potential for at-least patchy
 sea fog again tonight through Wednesday morning over the near
shore waters. A cold front will near the coastal waters late
Wednesday into Thursday with south winds decreasing slightly as
the pressure gradient relaxes. The front will also bring a chance
 for showers and a few thunderstorms.
