.SYNOPSIS...

High pressure aloft will continue to weaken into the weekend,
allowing for another day of diurnally driven showers and
thunderstorms today. Convective coverage looks to 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 next couple of days. Winds and seas will
begin to increase by Sunday as the pressure gradient begins to
tighten over the coastal region.
