Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 318 AM EDT Wed Oct 09 2024 Valid 00Z Thu Oct 10 2024 - 00Z Thu Oct 17 2024 An upper trough over Hawaii will weaken as it ejects northeastward with upper ridging becoming reestablished the rest of this week and lasting well into next week. This should allow for a more stable weather pattern and moderate to locally breezy trades. Showers should generally favor windward locations. A cold front approaching and dissipating north of the islands late this week and into the weekend should allow some weakening again of the trades before trades trend stronger next week with surface high pressure building to the north.
