Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 304 AM EDT Tue Sep 05 2023 Valid 00Z Wed Sep 06 2023 - 00Z Wed Sep 13 2023 A preferred composite of still reasonably compatible model and ensemble guidance indicates that upper troughing will shift gradually westward from the state and vicinity in the short term in a pattern with lightened island trades. A guidance composite is preferred to mitigate smaller scale differences consistent with predictability. Below normal moisture should overall limit shower activity for much of the state, but deeper tropical moisture is expected to lift into the southern islands Wednesday/Thursday to fuel some localized downpours over the Big Island. Trades may slowly return to moderate levels this weekend into early next week. Otherwise, expect slow to rise heights in the wake of upper trough passage into late week and next weekend along with a return to below normal moisture availability and shower activity. Schichtel
