A cold front extending southward from the intense surface low over
the Gulf of Alaska is expected to approach the northwestern
Islands through Sunday and then gradually wash out.  The
relatively weaker Trades that have been over the state this
weekend are expected to become slightly stronger from the east as
high pressure briefly builds near 30 degrees north.  By mid-week,
a col develops in the subtropical surface ridge as another cold
front approaches to the northwest of the Islands from another
strong North Pacific system, and this will cause surface winds to
veer to the southeast and weaken some, before gradually increasing
again by the end of the week as the high to the north builds again.

This will equate to a relatively uneventful weather pattern for
Hawaii this week with no significant moisture surges or rain
events expected.  There will be the typical windward showers
across the eastern Islands, and perhaps some sea/land breeze
induced showers.  Some enhanced swells from the North Pacific
storm systems will likely affect the northern coasts.
