The 21/00Z forecast cycle maintained a sufficiently consistent
forecast across the Pacific Ocean basin---to recommend either
deterministic ECMWF/GFS solution --- and/or some blend of both
through 27/12Z (mid-point day 6).

There seemed to be enough difference with the location of the
Subtropical  High ---to the northeast of Hawai'i (at 27/12Z) to
edge in favor of the 21/00Z GFS --- for tradewind intensity trends
during the latter portion of the medium range period (day 6-7).
