Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 317 AM EDT Fri Jul 11 2025 Valid 00Z Sat 12 Jul 2025 - 00Z Sat 19 Jul 2025 Surface high pressure north of the state into Saturday will drift more northward by Sunday and next week. This should allow for trade winds to weaken into early next week, with some strengthening again mid to late week as high pressure starts to build back westward north of the state. Clouds and showers through the next week will generally favor the typical windward locations. Santorelli
