.SYNOPSIS...
High pressure at the surface will continue to ridge across the
northern Gulf through the remainder of the weekend into early
next week, resulting in light to moderate onshore flow, low seas,
and dry conditions. Winds and seas begin to pick up a bit by
Tuesday as a front approaches from the north, tightening the
pressure gradient overhead and eventually bringing our next chance
of rain by early Wednesday.
