.DISCUSSION...High pressure building off the coast will bring a
warming and drying trend across Northwest California through
Tuesday. Today, winds will trend northwest in the afternoon and
some of the winds will make it down to the valleys. This pattern
is expected to continue into Tuesday. Winds will trend easterly
overnight the next few nights. Temperatures are expected to warm
by around 10 degrees today. Wednesday afternoon or overnight an
upper low has the potential to bring a shower or thunderstorm to
the site, but confidence is low on this. There is less than a 10
percent chance for this. This will also bring slightly cooler
temperatures.
