Synopsis for Lower Atchafalaya River LA to High Island TX out
60 NM including Sabine and Calcasieu Lakes and Vermilion Bay
936 AM CST Sun Dec 17 2017

.SYNOPSIS...
A brief bout of light offshore flow this morning with winds
turning back out of the southeast overnight as a front lifts back
to the north as a warm front. Some patchy marine fog has already
developed this morning south of Vermilion bay and this fog is
likely to expand and become more dense overnight tonight. This fog
layer could potentially persist through early Wednesday. The
nearly stalled frontal boundary will continue to provide a focus
for widespread showers and a few thunderstorms Monday into Tuesday
before the next cold front pushes through the area Wednesday
morning.
