Today's guidance agrees fairly well for the overall pattern
evolution through late next week.  Expect flow around the
southwest periphery of eastern Pacific high pressure to support
southeasterly low level winds on average from late this week into
the weekend, with some land/sea breezes possible at times. 
Precipitable water values will tend to be near to slightly above
normal.  An upper ridge building over/northwest of the main
islands during the weekend may lead to a gradual decrease in
rainfall from shower activity.  Next week should see a return to
more typical trades, but mostly on the light side as a front
settles down to 25-30N latitude.  Wind speeds may increase a bit
by late in the week as the front weakens and high pressure tracks
over the central Pacific.  Models and ensemble means signal a
decrease in precipitable water values relative to the weekend,
with the driest air likely to be over the southeastern islands. 
Low-predictability small scale impulses could provide localized
enhancement but otherwise expect most showers to be on the light
side during next week.
