Models and ensembles reasonably agree in showing a generally fair
weather pattern for Hawaii through the weekend with disrupted
trades and ridging aloft. Winds are forecast to gradually in
response to a stalling front to the northwest of the state.
Overall, these southerly mean winds should be weak to allow
land/sea breezes.

Southerly wind speeds may increase by Monday in the western
islands and Tuesday for most areas, ahead of another cold front.
This front has a better chance to reach the western islands around
midweek, supported by amplified upper trough approach and slow
passage to the north and increasingly over the state with time.
These features could increase and enhance rain chances as moisture
pools along the slow to progress front. Post-frontal winds will
increase later next week as high pressure re-bridges to the north
of the islands in an expected transition to a more windward
terrain focusing rainfall pattern to tap a lingering pooled
moisture plume.
