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

The next cold front will move across the area tonight. Ahead of the
front, expect decreasing winds and gradually lowering seas along with
some showers and thunderstorms and some patchy fog. Increasing and gusty
north to northeast winds and building seas can be expected behind the
front along with possible rain Thursday through Friday. Over the weekend,
northeast to east winds will swing around to the southeast and south
and strengthen. Seas will remain elevated, and also look for increasing
shower and storm coverage, especially Saturday night through Sunday
night. Fog is possible too. Lower rain chances and possible fog will
be in the forecast Monday through Monday evening as winds shift to the
southwest. The next cold front moves across the area Monday night, and
anticipate strengthening north winds and building seas to develop in
its wake. Caution flags and Small Craft Advisories can be expected
through much of this forecast period.
