Synopsis for High Island to the Matagorda Ship Channel out 60
nautical miles including Galveston and Matagorda Bays
606 AM CST Fri Jan 19 2018

.SYNOPSIS FOR HIGH ISLAND TO MATAGORDA SHIP CHANNEL OUT 60 NM...
Winds will gradually veer to the southeast today and strengthen in
response to a developing coastal trough near the lower Texas coast.
This system will help to enhance the chances for showers  and
isolated thunderstorms the next few days. The return of onshore
winds will also bring increased moisture and warmer  temperatures
through the weekend. This pattern will be favorable for the
development for sea fog starting tonight and persisting  into Sunday
evening, when the next cold front is expected to push  off the
coast.
