.Synopsis For High Island to the Matagorda Ship Channel Out 60 NM
including Galveston and Matagorda Bays.
Light to moderate onshore flow should continue through Thursday along
with Gulf seas of 2 to 4 feet. As patchy fog develops inland for
the next couple of nights, some of that fog may drift across the
upper portions of the Bays during the late night to early morning
hours. A weak frontal boundary will sag close to the coast late
Friday into Saturday then wash out. This boundary should serve as
a focus for some scattered showers and thunderstorms and also
result in some directionally variable winds on Saturday.
