Hawaii Extended Forecast Discussion
NWS Weather Prediction Center College Park MD
756 AM EDT Wed Sep 10 2014

Valid 00Z Thu Sep 11 2014 - 00Z Thu Sep 18 2014

Upper ridging should meander near the dateline and 30N, leaving
Hawai'i in relative but weak troughing through the period.
Ensembles indicate PW values to slowly climb from just below climo
values to just over climo values by early next week, especially
over the northern islands as some mid-upper level moisture sinks
southward. A 00Z GFS/ECMWF compromise should suffice.
Precipitation should be light amid relatively weak trades,
allowing local effects to drive the rainfall patterns.
