Models and ensembles continue to be very similar for most aspects
of the forecast during the next seven days.  Continued
southwestward motion of the upper low/surface reflection initially
crossing the state on early Wednesday will allow a more typical
trade pattern to become established through the middle of next
week.  A well-advertised band of moisture will cross the state
from east to west during Thursday/Friday and could enhance the
windward-focused showers somewhat.  Once this moisture departs,
most guidance anticipates precipitable water values declining to
about one inch during the early-mid week time frame--helping to
keep rainfall totals on the lighter side of the spectrum.  Fairly
brisk trades from the east-southeast late this week should trend
more easterly by the weekend or early next week.  Winds may become
a little stronger and east-northeasterly toward midweek as high
pressure migrates across the central Pacific.
