...A wetter pattern for the islands...

Guidance agrees in showing a fairly benign weather pattern for
Hawaii in the short term with disrupted trades and limited
rainfall chances. Winds veered from the south then southwest will
increase through the western islands with midweek frontal approach
as an amplified upper trough slowly passes to mainly to the north
of the state later this week. With this transition, expect
enhanced rain chances over the state as moisture pools within a
well defined and slow moving deep plume to fuel local activity.
Trades increase later week as high pressure re-bridges to the
north of the islands in an expected transition to a more windward
terrain focusing rainfall pattern with lingering pooled moisture.
Trades may slacken a bit by next weekend into early next week as
emerging troughing aloft settles over/just east of the islands.
