Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 400 AM EDT Wed Apr 13 2022 Valid 00Z Thu Apr 14 2022 - 00Z Thu Apr 21 2022 Surface high pressure north of Hawaii through the period should keep easterly trade winds moderate to locally breezy over the next week. This should result in just mainly some light showers favoring the typical windward locations the next couple of days. Beginning this weekend, models continue to show agreement on an upper shortwave settling east of or over Hawaii, bringing an extended period of higher moisture, especially across the Big Island and Maui. Expect an increase in rainfall across these islands into early next week when the shortwave should weaken/lift north as upper ridging tries to build back in over Hawaii. Santorelli
