Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 824 AM EDT Mon Mar 09 2015 Valid 00Z Tue Mar 10 2015 - 00Z Tue Mar 17 2015 The 9/00Z forecast cycle---including the deterministic guidance---appeared to be in very good agreement into day 6 (15/12z). This agreement included the passage of another mid-level trough and a 'fresh' mid-latitude Pacific airmass intrusion on day 3 (12/12Z). The differences between the 9/00Z deterministic GFS, ECMWF and Canadian are minimal for Hawai'i and the Subtropical Pacific. There are some subtle differences across the northern Pacific---but those differences should not alter the flow pattern scenario through the day-7 Hawai'i sensible weather forecast. The 9/00Z ECENS/NAEFS remains a solid baseline forecast---and the 9/00Z ECMWF-GFS deterministic runs appeared reasonable solutions---up to day 6. Vojtesak
