Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 830 AM EDT Wed Sep 04 2019 Valid 00Z Thu Sep 05 2019 - 00Z Thu Sep 12 2019 A favored composite of the latest models and ensembles indicates that high pressure cells bridging and building to the north and northeast of the islands will allow trades to increase up to moderate to locally breezy levels over the next week. This should support a pattern with mainly windward terrain focusing showers as enhanced with periodic passage of a series of deeper pockets of tropical moisture. The first passes over the region today/Thursday and a second in the Sunday-Tuesday timeframe. Schichtel
