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 to strong winds
through about Monday, followed by somewhat lower wind speeds next
week as the upper high shifts a little to the northwest of Hawaii
and upper troughing approaches from the East. Precipitable water
values should remain mostly below normal, helping to keep
primarily windward/mountain focused showers on the lighter side
most of the time. Models show good overall agreement on this
pattern, but some continued timing uncertainty with the upper
trough/low east of Hawaii. The 00z GFS is 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.
