Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 826 AM EDT Wed Oct 01 2014 Valid 00Z Thu Oct 02 2014 - 00Z Thu Oct 09 2014 The 1/00 UTC GFS/GEFS and ECMWF/ECENS were very much in mass field agreement heading into the weekend, then depart invof the central Aleutians--46N 173W by early next week with the depth of shortwave energy at mid latitudes. The surface trough migrating south-southeastward into the Subtropics along 30N 160W remains generally on track to be northwest of Kauai around the 5/12z time frame (day 4). The 1/00Z deterministic ECMWF depicts this surface trough as a slow-moving but organized surface low (1012mb ish) while the 1/00z deterministic GFS maintains more of a 'washed-out' stationary front. Recommend the more pessimistic approach with this wave...with the 1/00 UTC ECENS and GEFS means handling the pattern aloft in the north central Pacific beyond day 5. Overall, a sultry...more humid weather pattern over the entire region is expected this forecast period. Vojtesak
