Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 804 AM EDT Wed Sep 28 2016 Valid 00Z Thu Sep 29 2016 - 00Z Thu Oct 06 2016 Models and ensembles reasonably agree to develop and maintain an amplified mean trough position over the eastern Pacific through the weekend. This favors broad and moderately strong high pressure in its wake that should sustain moderate trades back across the islands. As the trades persist, remnant moisture from Hurricane Ulika is forecast by the Weather Prediction Center and National Hurricane Center to spread across the islands Sunday to Tuesday, leading to an increase in localized heavier rain potential.
