Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 317 AM EDT Sat Oct 23 2021 Valid 00Z Sun Oct 24 2021 - 00Z Sun Oct 31 2021 Trade winds should gradually strengthen through this weekend and drier air re-establishing across much of the state into early next week in a more stable upper pattern. Any showers should be limited to windward terrain areas as high pressure builds and bridges to the north of the islands. The guidance continues to suggest that upstream upper ridge amplification over the west-central Pacific may allow a rounding upper trough to dig southeastward towards Hawaii mid to later next week. This could bring a cold front towards the islands later next week increasing moisture chances and disrupting trades. Santorelli
