Hawaii Extended Forecast Discussion
NWS Weather Prediction Center College Park MD
418 AM EDT Wed Aug 27 2025

Valid 00Z Thu 28 Aug 2025 - 00Z Thu 04 Sep 2025

Predominantly zonal flow aloft will promote a relatively quiet
period across Hawaii over the next week. Light rain is expected
across the state with potential for isolated heavier rainfall over
Maui and The Big Island this weekend. The latest GFS and Euro
have continued to trend drier over these areas. The Euro has a
signal for a surge of tropical moisture to advect northward
toward the islands ahead of an approaching upper trough early
next week. Trade winds will likely persist and gradually weaken
over the next week.
