Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 716 AM EST Sat Jan 16 2016 Valid 00Z Sun Jan 17 2016 - 00Z Sun Jan 24 2016 No appreciable changes seen --- for the Hawai'i forecasts are in rather good agreement with the 16/00Z model cycle and their sensible weather projections. The subtle differences are located across the mid-latitude north central Pacific --- where the deterministic GFS is a slower---more compact solution at 500 millibars. This in turn makes for a slight slower mid-level trough progression into the Subtropics and for Hawai'i. Medium range overview --- still prefer a solution closer to the 16/00z deterministic ECMWF and ECENS means through next Wednesday-Thursday in the Gulf of Alaska. A 16/00Z GEFS/ECENS blend on/after Thursday for the north Pacific is a reasonable depiction --- at that time frame --- for the deep cyclone migrating east of --- and across the Dateline heading into day 7 (Friday). This system will be the next mid-latitude system that attempts to spread a mid-level trough into the Subtropics. Vojtesak
