Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 425 AM EDT Wed Oct 1 2025 Valid 00Z Thu 02 Oct 2025 - 00Z Thu 09 Oct 2025 A band of clouds and showers is expected for today and into the overnight hours primarily for windward and mountain locations. Tradewinds will gradually reduce across the region as the sub- tropical high weakens. An approaching cold front will cause the flow to become more southeasterly, which should allow for an increase in diurnally driven convection for the end of the week. Campbell
