The 5/00Z ECMWF and GFS and their ensemble means are very
agreeable with the overall flow pattern across the Pacific Basin.
A deep-layered ridge builds west-to-east along 30N next
week---bringing a fresh Tradewind flow pattern to the Islands.

Of note---the 5/00Z GFS/ECMWF deterministic guidance both generate
a closed 500mb vorticity center in the day 3-4 period invof 35N
140W. It becomes entrained in the Subtropical easterlies and
migrates westward towards the Islands between days 5 and 7. May
not be a significant sensible weather feature---but worth
mentioning since the feature (if it develops as 'progged') may
become a localized region of turbulent flow for aviation concerns
heading southwest from the Mainland.
