Models and ensembles continue to show good agreement on an upper
level low developing well north of Hawaii this weekend, which
should drive a cold front through the island chain. Guidance
suggests the axis of deepest moisture associated with this feature
should remains primarily east of Hawaii, so any showers should
favor windward areas into early next week. By the middle of next
week, as the upper level system pulls away, models show consensus
that upper ridging from the west-central Pacific should begin to
build back east across the state. As the resulting surface high
pressure builds to the north, this should allow for resumption of
more typical light to moderate trade winds. This pattern should
continue through the remainder of the week and into next weekend.
