Synopsis for Baffin Bay to Rio Grande out 60 nm-
402 AM CDT Tue Jun 27 2017

.SYNOPSIS...Light winds and slight seas will continue to be
supported by broad high pressure extending across the Western Gulf
of Mexico that meets a weak trough of low pressure anchored along
the Lower Texas coast through Wednesday. An upper level
disturbance in the area will continue to produce scattered to
numerous showers and a few thunderstorms. The high will move off
the southeast U.S. coast and strengthen Wednesday night and
Thursday while low pressure deepens across the southern Plains.
The high will remain stationary through Saturday while a general
trough of low pressure continues in west Texas. The gradient
between these systems will increase winds and seas Wednesday night
and Thursday, continuing through Saturday. Small Craft Advisories
may be needed for portions of the waters Thursday night through
Saturday.
