Synopsis for Lower Atchafalaya River LA to High Island TX out
60 NM including Sabine and Calcasieu Lakes and Vermilion Bay
1049 AM CDT Mon Oct 15 2018

.SYNOPSIS...
Showers and thunderstorms will return today, then linger through
Tuesday as a cold front moves into the coastal waters. A modest
offshore flow is expected over the northwestern Gulf by this
evening in the wake of this front. Rain and a few thunderstorms
will linger through mid-week as warm and moist flow aloft
overrides the cooler surface air north of the front. Winds are
forecast to strengthen further by mid to late week as high
pressure traverses the Ohio Valley and the gradient over the
northwest Gulf tightens. Winds will decrease Friday as the
gradient relaxes.
