Generally persistent high pressure north of Hawaii through much of
this week will allow for a fairly typical easterly trade wind flow
pattern with moderate to locally breezy speeds. This should
support mainly windward/mountain-focused showers along the eastern
facing terrain. An upper trough or cut-off closed low to the
northeast of Hawaii later this week should cause trades to shift
more northeasterly this weekend, and briefly back to the east by
early next week. An approaching trough from the north however by
mid next week could result in another north-northeasterly shift of
the trades, with some increase in speed as well. The latest models
and ensembles show very good agreement through much of the week on
this overall pattern, with lingering uncertainties still on the
approaching trough late in the period. The better consensus right
now suggests it should stay far enough away with minimal to no
impacts expected.
