The Hawaii domain will be under an upper level high this weekend,
and this should break down going into early next week.  An upper
low slowly approaches the far northwestern Islands through the
middle of the week, and a second closed low develops well to the
northeast of the state.  The ensemble means suggest that both of
these lows should remain well away from the main Islands through
the upcoming week.

Trade wind flow should generally be from the east most days, and
since the main surface high and its stronger pressure gradient
should be well north of the state, winds should be light to
moderate most days.  In terms of precipitation prospects, no major
rainfall events appear likely over the next 7 days, with good
overall agreement between the GFS and ECMWF on this scenario.
