Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 709 AM EDT Fri Apr 22 2016 Valid 00Z Sat Apr 23 2016 - 00Z Sat Apr 30 2016 The 22/00Z forecast cycle maintains good consistency across the Pacific Ocean basin --- with a broad Subtropical Ridge to prevail along 30N latitude for much of the forecast period. A mid-latitude surface front produces some weakening of the ridge axis along 30N 160W during the day7 period (the 29th) --- and may result in a slackening of the persistent trades across Kauai. Otherwise, little if any change is foreseen. Either 22/00Z deterministic ECMWF/GFS solution --- and/or some blend of both through 28/12Z (mid-point day 6) should provide good results. A 50/50 blend of the GEFS/ECENS means should hold the pattern in place for day 7. Vojtesak
