The models agree well with a rather strong surface high situated
to the northeast of Hawaii through Saturday, with a tight pressure
gradient over the state and resulting in windy conditions with
winds generally out of the east.  The high should gradually weaken
some going into Sunday, and the pressure gradient weakens going
into the being of next week.  The ensemble means differ some with
a cold front north of the state, with the ECENS a little quicker
to bring the boundary closer to the state by midweek.  In any
case, there will likely be a col in the subtropical surface ridge,
and thus lighter winds going into the early to middle part of next
week.

In terms of precipitation prospects, there will likely be more
trade wind based showers across the east-facing terrain through
the weekend, especially across the Big Island.  Other than that,
not major heavy rainfall events appear likely over the next seven
days.
