Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 805 AM EDT Thu Aug 11 2016 Valid 00Z Fri Aug 12 2016 - 00Z Fri Aug 19 2016 The 11/00Z forecast guidance --- including the deterministic GFS/ECMWF continue to build a strong ridge to the northeast of Hawai'i through day 6 (next Wednesday). Seasonal trades and sensible weather are anticipated. And across the tropical southeast Pacific, both pieces of deterministic guidance suggests some embedded mid-level wave propagation (in a ese-to-wnw fashion) heading towards the Big Island next Tuesday. The 11/00Z ECENS and GEFS means are slower than their deterministic counterparts with the wave propagation --- suggesting the lead mid-level is invof 140W and 20N on/around 17/12Z. Vojtesak
