Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 259 AM EDT Sun Jul 09 2023 Valid 00Z Mon Jul 10 2023 - 00Z Mon Jul 17 2023 Surface high pressure north of Hawaii should keep a persistent trade wind pattern in place through this week and next weekend. A pocket of increased moisture looks to move through the state (associated with former Tropical Cyclone Adrian) early this week leading to better chances for windward and mountain shower coverage. Otherwise, drier conditions and modest trades should persist through next weekend. Models continue to have a good handle on the overall pattern for the next week, with some uncertainties in the details. Santorelli
