The main subtropical high north of Hawaii will generally move
eastward around 32 degrees north through the end of the week, with
a col in the ridge developing over the far northwestern Islands by
Friday as a trailing front from a low pressure system well to the
north approaches, and this boundary will likely persist in that
general region through the weekend.  Meanwhile, an upper ridge
builds east of the Big Island by next weekend with good support
from the ensemble means. 

In terms of sensible weather, mainly scattered showers and typical
terrain enhancements are expected across the Islands with winds
generally out of the east at 10-20 mph on most days, with perhaps
some ESE flow at times.  No organized major heavy rainfall events
are anticipated over the next week as deep tropical moisture
remains generally south of 15 degrees north through the period,
and moisture near the previously mentioned front likely stays
northwest of most of the Islands.
