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

A late summer front stalls over Southeast Texas this weekend,
enhancing shower and thunderstorm activity through the holiday.
Winds over the weekend are expected to generally be light and
variable. However, locally stronger winds in the vicinity of
thunderstorms are likely. Winds are expected to turn back to being
broadly onshore later next week as the front drifts south and
dissipates. While rain chances should dwindle inland, daily isolated
to scattered showers and storms may persist over the Gulf.
