Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 754 AM EDT Tue Jun 02 2015 Valid 00Z Wed Jun 03 2015 - 00Z Wed Jun 10 2015 Diffuse upper-level troughing across the central Pacific is supported by a surface trough and high-amplitude flow in the Gulf of Alaska through much of this forecast period. The 2/00Z deterministic forecast guidance suggested that the persistence of a higher-amplitude wave pattern in the eastern Pacific will eventually spawn a cutoff 500mb circulation beyond the day 6 period --- and nestle this feature along 25N 160W. If this cutoff resembles the feature currently invof Kauai---then not much of a forecast concern beyond day 6--- and the going forecast looks on track for Hawai'i --- i.e. a persistent tranquil weather pattern.
