.Synopsis For High Island to the Matagorda Ship Channel Out 60 NM

Patchy fog may briefly spill into portions of the bays early this
morning. Light onshore winds today will shift to a more northerly
direction later today and this evening behind the passage of a
weak, dry cold front. Onshore flow returns on Thursday, eventually
resulting in an increase risk of fog Friday through Sunday
morning. The best chance of fog will be during the overnight and
morning hours. Some uncertainty regarding how widespread the fog
will be. The next front arrives Sunday, bringing a chance of
showers and gusty northeast winds in its wake. Small Craft
