The weakened remnants of a cold front are expected to drift across
the state on Friday, with PWs sufficient for scattered windward
showers. By the weekend, models and ensembles continue to show
good agreement on an upper level low developing well north of the
state, and the approach of another cold front towards the islands.
Guidance suggests the axis of deepest moisture associated with
this feature should remain primarily east of Hawaii, though
showers may be present across eastern portions of the state as the
front stalls across the region. 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 Hawaii. As the resulting surface high pressure builds
north of the state, this should allow for resumption of more
typical light to moderate trade winds which are expected to
continue through the remainder of next week.
