.SYNOPSIS...

High pressure aloft will begin to weaken overhead tomorrow and
Friday, allowing for the return of normal diurnally driven showers
and thunderstorms. Coverage looks to again be fairly scattered
tomorrow, but may become more widespread over the weekend as
ridging overhead fully breaks down.

Light to occasionally moderate onshore flow and low seas will
prevail through the remainder of the work week. Winds and seas
will begin to increase late Saturday into Sunday as a pressure
gradient begins to tighten over the coastal region.
