.SYNOPSIS...

Weak high pressure at the surface will ridge across the northern
Gulf of Mexico for the next several days. This will allow for
mainly light onshore flow and low seas. Through the next several
days, scattered to numerous showers and thunderstorms can be
expected each day. Coverage looks to be best across the coastal
waters through the morning hours. Elevated winds and seas will be
possible in the vicinity of the thunderstorms.
