Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 802 AM EDT Mon Apr 25 2016 Valid 00Z Tue Apr 26 2016 - 00Z Tue May 03 2016 Models and ensembles agree on upper ridging maintaining its presence in the central tropical/sub-tropical Pacific. For most of this week, the upper high will be bridged to the NW/N/NE of the state but will be interrupted by a brief weakness this weekend (as a system tracks south of the Aleutians). Ensembles indicate building heights again near the Dateline that should push into the NW islands by next Monday. Trades should remain modest through the period, but locally breezy. Precipitable water values should remain between about 0.75-1.40 inches as waves of moisture pass through the region. Precipitation is forecast to be light to perhaps locally moderate in the generally quiet pattern. Fracasso
