984 FXHW01 KWNH 070733 PMDHI Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 333 AM EDT Wed May 7 2025 Valid 00Z Thu 08 May 2025 - 00Z Thu 15 May 2025 Initial upper ridging over the main islands should get displaced by upper troughing just to the east of Hawaii around Thursday. This may support higher moisture and some increase in windward/mountain- focused showers. Regardless, a general easterly trade wind pattern will maintain over the state for at least the next week. Initial weaker wind speeds will increase to moderate or breezy as surface high pressure builds to the north of Hawaii later this week and weekend. Santorelli
