Latest guidance continues to show a typical easterly trade wind
pattern through the next seven days, supported by high pressure
meandering to the north of the state. Expect brisk winds through
about Monday or Tuesday, followed by somewhat lower wind speeds
later in the week as the upper high weakens and upper troughing
approaches from the East and eventually moves over or just north
of Hawaii. Through much of the week, windward/mountain focused
showers should stay on the lighter side but some increase in
moisture is possible with the upper low approach next weekend.
Models show good overall agreement on this pattern, but some
continued timing uncertainty with the upper trough/low east of
Hawaii. The GFS remains on the faster side, tracking the upper low
through Hawaii earlier than the better model consensus. Either
way, not much is expected in terms of sensible weather from this
feature besides overall lighter/weak wind speeds and some
increased showery activity.
