Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 659 AM EST Sat Dec 26 2015 Valid 00Z Sun Dec 27 2015 - 00Z Sun Jan 03 2016 An upper trough axis is expected to linger over the state through the holiday weekend and early next week. A favored guidance composite supports increased island trades and some pooling moisture/showers for this period as high pressure bridges to the north of the state. Expect weakening trades and more limited moisture through mid-later next week. Deeper mid-upper level trough passage to the north of the state may then force a surface front with enhanced showers toward the northern islands to ring in the New Year. Schichtel
