Synopsis: A coastal trough will persist over the offshore waters early this morning, then move slowly eastward and weaken by this afternoon. Scattered showers will be possible along and east of the coastal trough. Areas of dense fog will remain over the bays and nearshore coastal waters through the morning hours today. The onshore flow will gradually increase tonight with areas of dense sea fog expected again along the coast. The onshore flow will become weak to moderate on Sunday ahead of the next cold front. This front will move through the Middle Texas Coastal Waters Sunday night into Monday morning. This will result in a chance for showers ahead of the boundary, and a moderate offshore flow in the wake of the front on Monday. The offshore flow will diminish Monday night, as high pressure builds into Texas. Weak to moderate onshore flow will resume on Tuesday as the high moves east. Another weak cold front is expected to move through the area Wednesday resulting in a moderate northeast flow.
