Latest guidance is consistent in showing trades of varying
strength through the first part of next week.  Windward/mountain
locations will see the best focus for showers though some sea
breeze influence may occur during periods when trades are
relatively lighter.  Expect most rainfall to be on the light side.
 An area of somewhat increased moisture passing through late this
week and/or weekend followed by a weakness aloft could increase
amounts a bit during the latter few days of the period.

Through midweek the trades will be of moderate to brisk strength
while upper ridging will help to keep rainfall amounts light. 
Winds will ease somewhat late in the week, followed by a potential
for gradual strengthening from the weekend into next week as
eastern Pacific high pressure expands southward.  There is still
some degree of spread for how much added moisture passes through
the main islands Friday through the weekend and exactly when, with
an average of latest guidance preferred as the ECMWF/ECMWF mean
remain somewhat higher with precipitable water values than the
GFS/GEFS mean.  Drier air should move in early next week but the
consensus (excludes the 00Z GFS) shows the arrival of a weakness
aloft and that could serve to offset the moisture trend to some
degree.
