The upper trough that is currently situated over Hawaii along with
the adverse weather is forecast to slowly lift out of the region
by Monday, with a col remaining within the broader subtropical
ridge through midweek.  At the surface, the core of the surface
high should move eastward between 30-35 degrees north, maintaining
steady east-northeasterly trades through the end of the week, with
perhaps some veering to the east-southeast by next weekend.  The
ensemble means are in good agreement on the overall weather
pattern.

In terms of precipitation, rainfall intensity is forecast to
diminish by later Sunday, with mainly terrain enhanced showers for
the typical locations on the Big Island and Maui, and lighter
showers across the northwestern Islands.  No major events are
appearing on the horizon for the upcoming week.
