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.
