.Synopsis for Lower Atchafalaya River LA to High Island TX out
60 NM including Sabine and Calcasieu Lakes and Vermilion and Cote
Blanche Bays...

A weak frontal system will stall near the coast and wash out over 
the next day. This will keep light onshore winds along with a warm 
and moist air mass over cooler shelf waters to allow for the 
development of sea fog especially at night and during the morning. A 
low pressure system will develop on Saturday over the Southern 
Plains that will bring breezy southerly winds over the coastal 
waters along with building seas. Scattered showers and thunderstorms 
are expected late Saturday into Saturday night as the low pushes a 
Pacific cold front across the coastal waters. Breezy offshore winds 
will then develop behind the front for Sunday.

.Synopsis For High Island to the Matagorda Ship Channel Out 60 NM
including Galveston and Matagorda Bays.

A very weak front is nearly stationary near the coast. Winds are 
light, and from variable directions along this boundary. Therefore, 
patchy to areas of fog cannot be ruled out through mid-late morning. 
A slightly more favorable environment for fog is expected tonight 
into Friday morning with lighter east and southeast winds. Winds and 
seas will be on an upward trend beginning Friday in advance of the 
next weather system and front expected to pass across the waters 
Saturday afternoon and night. Showers and scattered storms will 
probably accompany this Pacific frontal passage.

.SYNOPSIS FOR THE MIDDLE TEXAS COASTAL WATERS...

A generally onshore light to gentle breeze (BF 2-3) can be expected 
through Thursday before increasing to moderate to fresh (BF 4-5) 
levels Thursday night through Sunday ahead of and behind our next 
cold front. The increase of wind coupled with wave heights between 4-
6 feet could lead to the issuance of a Small Craft Advisory closer 
to time. Precipitation is also expected with this frontal passage, 
with medium to high (40-80%) chances over area waters through the 
day Saturday. Winds will be more northerly post-front before 
returning to an onshore direction with gentle to moderate (BF 3-4) 
conditions by the start of next week. Patchy to areas of fog cannot 
be ruled out tonight, but slightly more favorable Thursday night and 
Friday morning with lighter east and southeast winds.
