...SMALL CRAFT ADVISORY IN EFFECT THROUGH LATE TONIGHT...

Synopsis: Coastal troughing continues to strengthen over the Gulf waters this evening before slowly moving eastward and weakening on Saturday. Strengthening onshore flow and increasing seas over the offshore waters have lead to SCA conditions which is expected through the overnight hours. Scattered to numerous showers along with isolated thunderstorms through Saturday are expected. Patchy to areas of sea fog are expected across the bays and near shore waters late tonight into Saturday morning. Weak to moderate onshore flow will occur 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 and isolated thunderstorms 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. Onshore flow will resume on Tuesday as the high moves east.
