Hawaii will generally be on the southern periphery of a large
surface high that will northeast of the state through the week
and into the weekend. The ensemble means suggest a col will 
develop within the subtropical ridge axis by next weekend north of
the far northwestern Islands with a weakening cold front 
approaching that region by next Sunday, but that front stays west
of the main Islands.

Low level trade wind flow should generally be out of the east most
days, with perhaps some ESE component next weekend. The usual
terrain enhanced showers can be expected most days across the
Islands, with perhaps a slight increase in showers by next Monday
across the northwestern Islands, but no major rainfall events are
expected over the next week.
