.Synopsis For High Island to the Matagorda Ship Channel Out 60 NM
including Galveston and Matagorda Bays.

Light onshore winds and low seas are expected going into the overnight
hours. We may see some fog redevelopment later this evening ahead
of a cold front that will be pushing into the bays between 3-6am.
Fog will lift, and precipitation will taper off, with the frontal
passage...but strong, gusty north and northeast winds and building
seas will fill in behind the front. Gusts to near or above gale 
are likely...especially in the Gulf. Winds and seas gradually 
diminish Monday morning, and return to a southeast direction by 
Monday night.
