The 4/00Z ECMWF and GFS and their ensemble means remain in good
agreement with the primary sensible weather features this 7-day
Hawai'i forecast period.

During the next 48 hours, the sensible weather pattern will be
tied to a slow-moving mid-latitude long wave trough and mid-level
low migrating eastward along 30 N latitude. This trough will press
slowly eastward to ~145W-140W around 6/12Z---then lift
northeastward towards the Mainland.

A mid-level southwest flow---with origins in the Equatorial
central Pacific should add additional cyclonic flow and moisture
to the base of the trough. 

Behind the trough, deep-layered ridging continues to be 'progged'
to build-in from the northwest and migrate eastward early next
week---extending across much of the Subtropical Pacific by the end
of this particular forecast period.

This deep-layered ridge is expected to generate a moderate to
brisk statewide tradewind pattern.
