Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 819 AM EDT Fri May 24 2019 Valid 00Z Sat May 25 2019 - 00Z Sat Jun 01 2019 Expect trade winds to return tonight, lasting through next week, keeping the Hawaii forecast rather quiet. Models continue to show very good agreement on a nearly stationary front well to the northwest of the main islands weakening as surface high pressure expands north of the state and into the subtropical eastern Pacific. This pattern would favor mainly windward and mountain showers for Hawaii, with leeward areas remaining mostly dry. Santorelli
