Guidance overall remains reasonably well clustered this week in a
pattern with seemingly above normal predictability. A favored
model composite supports quite breezy trades with surface high
pressure building and bridging to the north of the state. Showers
are likely to favor typical windward/mauka areas this week, but
may occasionally spill into leeward areas.

A consistent recent forecast signal continues to show deep
moisture advecting into at least the Big Island by later this
weekend into early next week with origins 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. System proximity in this
scenario could favor a much wetter and windy period along with
potential maritime hazards.
