.SYNOPSIS FOR HIGH ISLAND TO MATAGORDA SHIP CHANNEL OUT 60 NM...
Showers and thunderstorms off the Louisiana coast are expected to
expand westward this afternoon, but should also be more
isolated/scattered in nature. A tightened onshore pressure
gradient will generate slightly higher wind speeds the next couple
of days, especially overnight. Winds will slacken for the middle
and late week as an area of high pressure develops over the
central Gulf.
