Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 353 AM EDT Wed Jun 25 2025 Valid 00Z Thu 26 Jun 2025 - 00Z Thu 03 Jul 2025 Above normal moisture is in place across much of Hawaii Wednesday, while a weak upper trough aloft allows for a raised inversion. This will equate to a wet trade wind pattern as moderate to breezy trades are in place. Showers should be passing across most islands but linger for Kauai where the moisture and troughing are maximized. Into late week, moderate trades should continue but drier conditions are expected. An upper ridge will drift over the eastern islands and eventually build to the west by this weekend. Thus showers should decrease but a few showers over windward and mauka areas are still possible. Will continue to monitor the pattern into next week, but currently it appears that early to midweek another upper trough axis could develop northwest of the islands, while the surface pressure gradient could weaken and decrease trades, especially for Kauai/Oahu.
