 .Synopsis For High Island to the Matagorda Ship Channel Out 60 NM
 including Galveston and Matagorda Bays.
 
 Patchy, dense fog will continue in the Bays this morning, and
 then redevelop late this evening into early Sunday morning as
 warmer air overspreads the cooler waters. Light onshore winds and
 low seas will generally prevail until the next cold front and
 associated scattered showers and isolated thunderstorms pass
 through the bays prior to sunrise Sunday. This will bring an end
 to the fog threat, but gusty north and northeast winds and
 building seas will fill in behind the front. Gusts close to gale
 are possible in the Gulf. Winds and seas gradually diminish Monday
 morning, and return to a southeast direction by Monday night.
