Latest model and ensemble solutions remain reasonably well
clustered for much of the coming week in a pattern with seemingly
above normal predictability. A favored guidance composite
indicates that island trades will strengthen and maintain breezy
levels as surface high pressure builds and bridges to the north of
the state. Through the period, some showers are possible favoring
typical windward/mauka areas, but occasionally spilling into
leeward areas. Showers may be supported by nearby mid-upper level
troughing and periodic moisture over the next few days, but
widespread heavy rain is not expected in this period.

However, guidance signals are growing that deep moisture could
advect into at least the Big Island later weekend into early next
week from possible tropical low/convective developments now being
monitored well to the southeast of the islands by the National
Hurricane Center and Central Pacific Hurricane Center.
