The core of the subtropical high is expected to be nearly anchored
in place around 35N/145W through the upcoming week, and the
Islands will be on the southwestern periphery of this high with
good agreement among the ensemble means for this scenario.  This
will also be co-located with a building upper level high in the
same general region.  There may be a weak upper level trough that
passes by for the middle of the week, but it should not have a
noticeable effect on the local weather for most locations.  A
stronger disturbance approaches the far northwestern Islands by
next weekend, but the effects of that will likely stay well out to
sea.

In terms of sensible weather, low level trades should generally be
out of the east with some occasional ESE component at times, with
moderate flow velocities expected.  Most of the terrain enhanced
showers should be across the Big Island, and lighter QPF across
the other Islands.  No major surges of tropical moisture are
expected over the next week.
