.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.
