962 FXHW01 KWNH 100637 PMDHI Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 237 AM EDT Fri Oct 10 2025 Valid 00Z Sat 11 Oct 2025 - 00Z Sat 18 Oct 2025 Model and ensemble solutions seem reasonably well clustered, bolstering overall forecast confidence. Expect land/sea breeze conditions today with scattered showers focusing over those convergence areas under a favorable weakness aloft and moisture. Winds should back to a more typical and light easterly trade direction this weekend. An upper low is forecast to dig south to the state early next week and then linger into later next week. This would act to further pool moisture as winds respond/shift southeastward. A rising inversion and increasing lift should further yield increased rain/downpour chances in a wet period. Schichtel $$
