Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 822 AM EDT Wed Oct 26 2016 Valid 00Z Thu Oct 27 2016 - 00Z Thu Nov 03 2016 Models and ensembles reasonably agree that a weakening surface boundary will move through the islands today through Thursday will bring light showers to the region. After that, high pressure will build to the north of the islands in the wake of system passage. Expect a period of moderate to locally breezy trades and windward terrain based showers later this week into early next week under a weakness aloft. Schichtel/Fanning
