.SYNOPSIS FOR HIGH ISLAND TO MATAGORDA SHIP CHANNEL OUT 60 NM...
Fairly modest winds and seas are expected through the period with
light to occasionally moderate south to southwest winds over the
weekend. A weak cold front will attempt to push off the coast on
Tuesday and Wednesday leading to light variable winds followed by
northeasterly winds. Exact timing and location of this front
remains uncertain. The front will lead to an increase in shower 
and thunderstorm activity. Locally higher winds and seas are 
expected in and near thunderstorms. The front washes out by the
end of the week leading to another period of onshore flow.
