Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 728 AM EST Mon Nov 06 2017 Valid 00Z Tue Nov 07 2017 - 00Z Tue Nov 14 2017 Models and ensembles generally agree that upper ridging over the region will weaken and shift westward this week and will likely be replaced by troughing this weekend into next week, centered along 150W. This supports a fairly quiet pattern with generally light windward/mauka showers on via modest trades. Precipitable water values are forecast to remain near to below average for early November until next week with any surface boundary likely staying north of the region. Fracasso
