Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 751 AM EDT Tue Sep 27 2016 Valid 00Z Wed Sep 28 2016 - 00Z Wed Oct 05 2016 Models, including most ensemble members, have clustered toward greater agreement for an amplified longwave trough forming across the eastern Pacific by the end of this week, which then favors a broad and moderately strong high pressure in its wake that should sustain moderate trades across the islands through next weekend. As the trades persist, moisture from T.D. 19 may spread across the islands anytime from Sunday into next Tuesday which is the current solution spread, leading to an increase in rain chances. The consensus of the models shows the eastern Pacific trough weakening by early next week, which if correct, would allow the trades to weaken then. James
