753 FXHW01 KWNH 130700 PMDHI Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 300 AM EDT Mon Oct 13 2025 Valid 00Z Tue 14 Oct 2025 - 00Z Tue 21 Oct 2025 Model and ensemble solutions continue to seem reasonably well clustered, bolstering overall forecast confidence. Light south- easterly trades over the next few days should increase mid-later week into next weekend as high pressure settles to the northeast and north of the state. Meanwhile, an unsettling upper low/trough remains forecast to dig south toward the state early week and then linger in vicinity mid-late week before shifting slowly westward. Pooling moisture and increasing lift favor increased chances for heavier rains and a few thunderstorms in a wet period to monitor. Schichtel $$
