A moisture axis along an old front will continue to focus west of
the islands as drier air slowly works into the state as trades
slowly back from east to east-northeast. In this pattern,
lingering moisture will support some windward/mauka showers over
the next couple of days. Trades should weaken later week with
gradual frontal approach that will lead to more of a daylight sea
breeze and overnight land breeze pattern. Models and ensembles
seem in a bit better agreement in showing deep closed low/trough
development to the north of the state this weekend that will help
drive the front underneath and force onset of deeper moisture and
heavier precipitation threat for the state, with post-frontal
conditions working in for early next week.
