Synopsis for Lower Atchafalaya River LA to High Island TX out
60 NM including Sabine and Calcasieu Lakes and Vermilion Bay
1110 PM CST Fri Dec 15 2017

.SYNOPSIS...
An upper trough will approach the area late Saturday into Sunday
resulting in widespread showers and thunderstorms. East and then
southeast winds are forecast to increase as an associated weak
area of low pressure develops and tracks northeast along the
Texas coast into the Sabine River Valley. The south winds will
aid in  transporting very moist air northward atop relatively
cool  nearshore shelf waters, so there is some potential for
marine fog  starting late Saturday night and possibly persisting
for a few  days. A second upper trough follows Monday keeping
rain chances  elevated for the early part of next week.
