Today's models and ensembles maintain good agreement and
continuity for the expected pattern over the next seven days. 
High pressure to the north of the state will maintain brisk to
strong trades for most of the period, though with the potential
for some moderation of wind speeds by next Tuesday-Wednesday as
the high trends a little weaker.  Expect windward/mountain focus
for showers that could occasionally stray to other locations, with
rainfall tending to be in the lighter half of the spectrum per
guidance consensus. An area of greater moisture passing by to the
north and brushing the northwestern islands may enhance totals a
bit around Friday-Saturday.  Otherwise guidance generally keeps
precipitable water values below climatology.  With the westward
departure of an upper low, ridging (or at least fairly high
heights) should prevail through the weekend. The next upper level
feature of interest will be a low which guidance agrees should
approach from the east by next Wednesday.
