Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 712 AM EST Wed Jan 06 2016 Valid 00Z Thu Jan 07 2016 - 00Z Thu Jan 14 2016 It is still evident that a mainly transitional pattern will prevail through early next week as strong westerlies north of the islands slow down...amplify...and split across the eastern Pacific due to the strong downstream block. The result will be periodic frontal passages and/or slow-downs north of the island...including Friday...this weekend...and again possibly early next week. This should produce disruptions in the trades as well as periodic increases in modest rainfall chances. A composite guidance solution is generally preferred that emphasizes more deterministic guidance early and ensemble guidance late. Schichtel
