Surface high pressure rebuilds northwest of the state near 30-35
degrees north through early in the week, with mainly ENE trade
wind flow expected, and then the high becomes centered north of
the state by Thursday into Friday, with good overall model
agreement across the Hawaii domain.

In terms of rainfall prospects, mainly trade wind induced showers
can be expected most days across the windward terrain. The
ensemble means suggest an upper trough could develop near 150
degrees west by midweek, and this may result in a slightly greater
coverage of showers during this time, but nothing major expected.
