A developing surface low near 30 degrees north will continue to
lift northeastward over the next couple of days with a weakening
cold front approaching the Islands by Saturday.  High pressure
builds in north of the state this weekend followed by another
weakness in the subtropical ridge by early next week.  There are
significant differences between the 12Z ECENS and 00Z GEFS mean by
Sunday and beyond, with the ECENS stronger
with the next storm system passing north of the state.

This will equate to a relatively uneventful weather pattern for
Hawaii through early next week with no significant moisture surges
or rain events expected.  There is some hint in the guidance for
some more widespread rainfall by Wednesday as an upper trough
approaches.  There will be the typical windward showers across the
eastern Islands, and perhaps some sea/land breeze induced showers,
although this activity should mainly be light.
