The latest models and ensembles generally agree upon the overall
weather flow pattern effecting the Hawaiian Islands for much of
the next week and a composite solution seems reasonable. High
pressure
to the north then northeast of the state should support moderate
to locally breezy trades into early next week before easing a bit.
In this pattern, periods of banded moisture over the islands
underneath a lingering mean weakness aloft should combine with
trades to produce some windward terrain enhanced showers, with
some activity working leeward on the smaller islands. Additional
troughing aloft from the northwest midweek could support more
showers, followed by some uptick again of later week trade flow as
supporting high pressure becomes re-established in the wake of
trough passage, but moisture may be reduced.
