Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 725 AM EDT Mon Jun 23 2014 Valid 00Z Tue Jun 24 2014 - 00Z Tue Jul 01 2014 Latest models and ensembles still reasonably agree that high pressure building/bridging to the north of the state should favor a tendancy for increased island trades this week in a pattern with mainly scattered windward terrain based showers. Trades may be effected by the weekend by approach of an upper low/trough with a favored composite guidance solution position held northeast of the state. Guidance is now in better agreement with this feature, bolstering forecast confidence. Schichtel
