Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 326 AM EDT Tue May 21 2024 Valid 00Z Wed May 22 2024 - 00Z Wed May 29 2024 An upper low northwest of Hawaii should weaken by later this week, with models continuing to show good agreement the better moisture and heaviest rainfall should stay west of the main islands. By late week/next weekend, surface high pressure looks to build north of Hawaii and a more typical easterly trade wind pattern should prevail over at least the next week. This supports a mainly windward and sea breeze focus for showers with some locally breezy trades at times. Santorelli
