Breezy trade winds over Hawaii should weaken and shift towards the
southeast on Thursday, as a cold front pushes through much of the
island chain from Northwest to Southeast Thursday-Friday. Models
show good agreement that any deeper ITCZ moisture pulled northward
should stay east of the state, resulting in merely modest showery
activity with the frontal passage. The front should weaken over
the state by Saturday, with breezy to gusty easterly winds
returning by Sunday and lasting through much of next week as high
pressure builds to the north and east. Expect precipitation to
favor windward facing coastlines. Models show signs of an upper
level low lingering east of the island chain next week, which may
bring the potential for deeper moisture to be drawn up towards
Hawaii. Confidence in the details of this is low at this point in
time.
