An upper low northwest of Hawaii should weaken by later this week,
but combination of energy with another low to its west should keep
a lingering trough west/northwest of Hawaii into next week. Models
do continue to show good agreement that the better moisture and
heaviest rainfall should stay west of the main islands though,
some some enhanced showers could make it to Kauai depending on
exactly how close the trough sets up to the west. Surface high
pressure building north of Hawaii this weekend and next week will
maintain a more typical easterly trade wind pattern, supporting a
mainly windward and sea breeze focus for showers with some locally
breezy trades at times. A cold front approaching the western
islands later next week may allow for trades to shift more
southeasterly.
