Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 815 AM EDT Mon Oct 12 2015 Valid 00Z Tue Oct 13 2015 - 00Z Tue Oct 20 2015 During Mon-Tue an initial surface trough and band of enhanced deep moisture should gradually weaken/dissipate. This will likely support a lighter trend for shower activity tending to focus along sea breeze boundaries given the light prevailing winds. An upper trough passing by to the north of the state will help to push a weak front through the area Tue-Wed. Trailing high pressure moving steadily eastward along 30N latitude will then bring north-northeasterly winds turning more easterly by next weekend. Trade flow should focus the best organized shower activity over windward terrain from Wed onward. Also by next weekend latest guidance has trended toward more of an upper level weakness developing just west of the state and greater potential for some enhanced moisture to move into the area from the east. Some of this moisture may originate from T.S. Nora, for which the Central Pacific Hurricane Center is currently issuing advisories. Based on the 0900 UTC CPHC advisory, Nora is forecast to weaken to tropical depression status by Fri night with a track reaching 149.5W longitude at that time. Rausch
